Background and Objectives: Transcatheter aortic valve replacement (TAVR) in large aortic annuli poses challenges due to limited valve-size options and increased complication risks. The aim is to evaluate the safety and performance of XL sizes (30.5 mm and 32 mm) of the Myval transcatheter heart valve (THV) for treating patients with severe aortic stenosis and large aortic annuli. Material and Methods: This retrospective observational study included consecutive patients undergoing TAVR with XL sizes of the Myval THV between December 2023 and December 2024 at a single centre. During this period, 146 TAVI procedures were performed, of which 15 patients (10.3%) with large aortic annuli (mean systolic annular area 786.5 ± 48.2 mm²) received XL valves and were included in the present analysis. Patients were followed up at discharge, 3–6 months, and 1 year. Patient evaluation included echocardiography and clinical assessments following the Valve Academic Research Consortium-3 criteria. Results: All patients were male, with a mean age of 79.1 ± 5.9 years. Technical success was achieved in 100% of cases. At discharge, none of the patients had moderate or greater paravalvular leakage (PVL); 11 patients had no PVL, while 1 had trace and 3 had mild PVL. The mean effective orifice area (EOA) improved from 0.75 ± 0.15 cm² at baseline to 2.31 ± 0.21 cm² at discharge (p < 0.0001). At the 12-month follow-up, the mean EOA was 2.4 ± 0.3 cm², and no moderate or severe PVL or major adverse clinical outcomes were observed. One patient required a permanent pacemaker implantation due to an atrioventricular block. Conclusions: The XL sizes of Myval THV showed both safety and efficacy in patients with large aortic annuli, demonstrating acceptable hemodynamic performance and low complication rates. However, large-scale studies with longer follow-ups are needed to validate these findings in diverse populations. Full article

Background/Objectives: Permanent pacemaker (PM) implantation is a well-recognized complication of transcatheter aortic valve implantation (TAVI), but its long-term prognostic impact remains uncertain. To evaluate the association between PM implantation and all-cause mortality in TAVI recipients. Methods: We performed a post hoc analysis of a prospective single-center TAVI registry (2016–2020). The primary endpoint was all-cause mortality at 1 and 5 years. Cox regression and Kaplan–Meier analyses were applied. Validation was performed using the nationwide AUTHEARTVISIT claims database. Results: Among 1114 consecutive TAVI patients (mean age 81  ±  5.8 years; 49.8% female), 120 (10.8%) had a pre-existing PM (Pre-PM), and 153 (13.7%) received a new PM within 30 days post-TAVI (Post-PM). Post-PM patients were older (p = 0.006), more often male (p < 0.001), had higher Troponin T levels (p = 0.002), more pre-existing right bundle branch block (p < 0.001), and longer QRS duration (p < 0.001) compared to patients without PM. In multivariate analysis, one-year mortality was associated with Troponin T (p = 0.002) and NT-proBNP (p = 0.002) serum levels. Pre- or Post-PM status was not associated with 1-year mortality (p = 0.455, p = 975). However, Pre-PM status was independently associated with 5-year mortality (HR 1.4, 95% CI: 1.0–1.9, p = 0.03), whereas Post-PM status was not (HR 1.2, 95% CI: 0.8–1.6, p = 0.22). Findings were confirmed in the nationwide AUTHEARTVISIT cohort. Conclusions: In this large, real-world TAVI cohort with national validation, Post-PM status was not associated with mortality at 1 or 5 years. By contrast, Pre-PM identified patients at higher long-term risk, possibly reflecting underlying cardiac disease. Full article

Background and Objectives: Patients with impaired left ventricular ejection fraction (LVEF) undergoing transcatheter aortic valve implantation (TAVI) remain at high risk for adverse outcomes despite successful procedures. Sodium–glucose cotransporter-2 inhibitors (SGLT2i) improve outcomes in heart failure, but their long-term impact after TAVI is not well established. Materials and Methods: This single-center retrospective study included patients with LVEF < 50% who underwent transfemoral TAVI between January 2015 and September 2025. Patients were stratified according to SGLT2i use. The primary outcome was a composite of all-cause mortality and heart failure (HF) hospitalization requiring intravenous diuretics. Secondary outcomes included all-cause mortality, HF hospitalization, and changes in echocardiographic parameters at 6 months. Inverse probability of treatment weighting (IPTW) based on propensity scores was applied to adjust for baseline differences. Time-to-event analyses were performed using IPTW-weighted Cox models and adjusted survival curves. Results: The study included 226 patients (78 SGLT2i users, 148 non-users) with a median follow-up of 37 months. After IPTW adjustment, SGLT2i use was associated with a lower rate of the composite outcome (32.8% vs. 50.8%, p = 0.019) and a lower crude long-term mortality (32.8% vs. 47.4%, p = 0.056). Acute kidney injury after TAVI occurred less frequently among SGLT2i users (3.4% vs. 17.4%, p = 0.013). In IPTW-weighted Cox analyses, SGLT2i use was associated with a reduced risk of all-cause mortality (HR 0.57, 95% CI 0.32–0.98) and the composite outcome (HR 0.56, 95% CI 0.33–0.96). SGLT2i users demonstrated greater reductions in left ventricular end-diastolic diameter at 6 months. Conclusions: In patients with impaired LVEF undergoing TAVI, SGLT2 inhibitor therapy was associated with improved long-term survival, better composite outcome-free survival, and lower rates of post-TAVI acute kidney injury. Larger prospective studies are warranted to confirm these findings. Full article

Background: Frailty strongly influences outcomes after transcatheter aortic valve implantation (TAVI), but conventional risk models insufficiently capture functional and cognitive vulnerability. We compared conventional surgical risk scores with multidimensional frailty assessment and a biological score. Methods: This observational registry included 528 consecutive patients with severe symptomatic aortic stenosis undergoing TAVI between January 2019 and November 2024. Frailty was assessed using the Essential Frailty Toolset (EFT), Katz Index, and cognitive screening, alongside French Aortic National CoreValve and Edwards 2 (FRANCE-2) and Age, Creatinine, and Ejection Fraction (ACEF) scores. HALP was calculated as (haemoglobin × albumin × lymphocytes) ÷ platelets. Primary endpoints were 30-day, 6-month, and 1-year all-cause mortality. Secondary outcomes included non-fatal major adverse cardiovascular events (MACE), complications, and quality-of-life improvement. Results: One-year mortality was 12.7%. EFT and Katz Index showed the strongest discrimination for 1-year mortality (AUC 0.72 and 0.75), outperforming EuroSCORE II and STS-PROM (AUC 0.66 and 0.68). After adjustment, EFT (HR 1.91, 95% CI 1.47–2.48), Katz Index (HR 0.57, 95% CI 0.47–0.70, and cognitive impairment (HR 2.24, 95% CI 1.34–3.75) independently predicted 1-year mortality. HALP was not associated with outcomes. FRANCE-2 independently predicted 1-year MACE (HR 1.24, p = 0.019). Conclusions: Functional frailty and cognitive impairment add prognostic value beyond conventional comparator models, whereas HALP does not. Brief functional and cognitive screening may help Heart Teams identify patients who need closer peri-procedural optimisation, rehabilitation planning, and discharge support rather than relying on surgical risk scores alone.

Background: Renal dysfunction remains a frequent complication after transcatheter aortic valve implantation (TAVI). Although contrast exposure and baseline renal impairment are established risk factors, the influence of structural valve characteristics, including valve diameter and prosthesis platform, on early renal outcomes is not well defined. This study evaluated whether valve size and valve platform independently affect early post-procedural renal function. Methods: This retrospective cohort study included 410 consecutive patients undergoing TAVI between 2018 and 2021 with complete pre- and post-procedural renal biomarker data. Of these, 371 patients with complete covariate data were analyzed in multivariable models. Serum creatinine and estimated glomerular filtration rate (eGFR) were assessed within 72 h before and after TAVI. Renal function change was calculated as absolute differences. Acute kidney injury (AKI) was defined according to KDIGO criteria. Correlation analyses and multivariable linear and logistic regression models were performed. Results: Median valve diameter was 26 mm (IQR 26–29). Renal function remained largely stable, with a median creatinine change of −0.06 mg/dL and median eGFR change of +4.0 mL/min/1.73 m². Valve diameter was not associated with creatinine change (ρ = −0.047, p = 0.330) or eGFR change (ρ = 0.053, p = 0.278). KDIGO-defined AKI occurred in 56 patients (13.7%) and did not differ by valve platform (p = 0.719) or diameter tertiles (p = 0.204). Conclusions: Valve diameter and platform were not independently associated with early renal outcomes after TAVI. Baseline renal function and contrast exposure were the principal determinants of post-procedural renal trajectory. Full article

Background and Objectives: Porcelain aorta is an anatomy-driven high-risk phenotype characterized by extensive calcification of the ascending aorta, which complicates surgical aortic valve replacement by increasing embolic and technical hazards during cannulation and cross-clamping. As transcatheter aortic valve implantation (TAVI) expands into younger and low-surgical-risk populations, porcelain aorta creates a distinct clinical dilemma: optimizing short-term procedural safety while ensuring durable long-term outcomes and preserving future treatment options. Materials and Methods: We performed a targeted literature search of MEDLINE/PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL), with the last search conducted on 31 January 2026. We synthesized contemporary clinical evidence on TAVI in patients with imaging-defined porcelain aorta, focusing on neurological outcomes, procedural strategies to reduce embolic risk, access considerations, valve performance, cerebral embolic protection, and implications for lifetime valve management (including coronary access and feasibility of future valve-in-valve interventions). Results: The evidence base specific to porcelain aorta in the contemporary TAVI era is limited and largely observational. Across published cohorts, TAVI avoids direct ascending aortic cannulation and cross-clamping and is generally associated with favorable early safety, with a recurring directional signal toward lower neurological risk compared with surgical strategies that require manipulation of a severely calcified ascending aorta. Interpretation is constrained by heterogeneity in porcelain-aorta definitions, patient selection, valve platforms and access routes, as well as, variability in neurological endpoint definitions and adjudication. Conclusions: In patients with porcelain aorta, TAVI is frequently favored because it minimizes ascending aortic manipulation and may mitigate neurological and procedural hazards. In younger and low-risk patients, Heart Team decision-making should incorporate lifetime management principles, including access planning, preservation of future coronary access, and procedural strategies to reduce embolic risk (with consideration of cerebral embolic protection when appropriate).

Background: Transcatheter aortic valve implantation (TAVI) is increasingly performed in fluoroscopy-intensive environments, raising concerns about occupational eye lens dose (equivalent dose to the eye lens, Hp (3)) and the risk of radiation-induced cataract, particularly after the reduction of recommended annual eye lens dose limits to 20 mSv. Purpose: To summarize evidence on eye lens radiation exposure during TAVI, identify procedural and occupational determinants, and review strategies to reduce exposure with a focus on imaging optimization. Methods: We performed a narrative review of observational and prospective studies reporting direct eye-level dose measurements or validated surrogate eye lens dose estimates (head-level, chest-level, or DAP-normalized) during TAVI and related structural heart procedures. This approach was chosen to provide a qualitative synthesis of the available evidence rather than a formal systematic review. Results: Reported operator eye lens doses typically ranged from 30 to 110 µSv per procedure, with higher exposure during transapical/transaortal access and among staff working close to the patient (e.g., anesthesiologists and circulating nurses). Additional shielding and lead-free drapes reduced normalized eye dose by approximately 25–40%, and RADPAD^® use reduced operator eye-level dose from 24.3 to 14.8 µSv per procedure (p = 0.008). At these levels, cumulative exposure may approach recommended regulatory limits after approximately 150–300 procedures, depending on role, access route, and shielding practices. Conclusion: In conclusion, Occupational eye lens exposure during TAVI is clinically relevant and strongly influenced by access route, staff positioning, and imaging-system use. Dose reduction should combine routine eye protection and dedicated eye-level dosimetry with imaging optimization (low pulse-rate fluoroscopy, minimized Digital-Subtraction-Angiography (DSA)/cine acquisitions, tight collimation, avoidance of unnecessary magnification, and correct positioning of ceiling-suspended shields and table skirts).

Background and Objectives: Over the past decade, transcatheter aortic valve replacement (TAVI) has evolved from a treatment for inoperable patients to an established option across all risk categories. In parallel, the Perceval sutureless valve has demonstrated safety and efficacy especially for minimally invasive surgical aortic valve replacement (AVR). Despite the advances of both TAVI and Perceval, robust long-term data and clear patient selection criteria are still lacking. This retrospective single-center study reports the outcomes of patients undergoing isolated AVR with the Perceval sutureless valve or with TAVI. Materials and Methods: We retrospectively reviewed consecutive patients undergoing isolated AVR at our institution between April 2013 and December 2024. Of 1006 eligible patients (424 TAVI; 582 Perceval), propensity score matching was performed for age, sex, EuroSCORE II, body surface area, and comorbidities, yielding 197 matched pairs. Primary endpoints were all-cause and cardiovascular mortality. Secondary endpoints included acute kidney injury, permanent pacemaker implantation, stroke, pericardial effusion, ICU stay, and overall hospital stay. Clinical and echocardiographic follow-up was obtained by medical-record review and routine echocardiography, with an additional prospective clinical and echocardiographic evaluation at 6–12 months. Results: Postprocedural paravalvular leak was significantly more frequent after TAVI than after Perceval AVR (23.4% vs. 2.5%; p < 0.001). At 6–12 months, TAVI was associated with greater aortic regurgitation and higher rates of para- and intra-prosthetic leak (both p < 0.001) and higher mean transvalvular gradients, particularly in small and medium valve sizes. ICU and overall hospital stay were longer after Perceval implantation (both p < 0.001). New permanent pacemaker implantation was numerically higher after TAVI (11.2% vs. 5.6%; p = 0.063). Early mortality was similar; however, 1-year mortality was higher after TAVI (16.2% vs. 9.1%; p = 0.045), and Kaplan–Meier analysis demonstrated better overall survival with Perceval (p < 0.001), while cardiovascular survival did not differ significantly (p = 0.851). Conclusions: Our study underscores the importance of meticulous patient selection when choosing between TAVI and Perceval. Perceval implantation was associated with better long-term overall survival than TAVI in the propensity-matched cohort. Paravalvular leaks were more frequent after TAVI and associated with poorer survival. Both approaches achieve excellent outcomes; however, differences in long-term survival and valve performance highlight the need for a personalized treatment strategy guided by a multidisciplinary heart team.

Background: Transcatheter aortic valve implantation (TAVI) is increasingly used across all risk groups, meaning more patients are living long-term with transcatheter bioprosthetic valves. These patients are often multimorbid and vulnerable to both thrombotic and bleeding complications. Optimal antithrombotic therapy remains uncertain due to differences in trial design, patient demographics, and procedural practices. Methods: We undertook a narrative review that included randomised controlled trials, observational studies, biomarker research, and guideline recommendations on post-TAVI antithrombotic therapy. We evaluated the available evidence for antiplatelet and anticoagulant strategies after TAVI, predictors of bleeding and thrombotic complications, to identify emerging approaches using biomarkers for personalised risk stratification. Results: Thrombotic events after TAVI are predominantly early and procedural in origin, while new-onset atrial fibrillation (AF) leads to substantial late risk. Subclinical leaflet thrombosis is frequent, but its clinical significance remains uncertain, as anticoagulation reduces CT-detected leaflet abnormalities without improving clinical outcomes. Early bleeding within the first 30 days remains a principal contributor to mortality, influenced by frailty, vascular access, comorbidity, and intensity of antithrombotic therapy. Randomised evidence consistently supports a minimalist, indication-driven regimen: single antiplatelet therapy for patients without an oral-anticoagulation (OAC) indication, and OAC monotherapy for those with AF. Routine OAC use in unselected patients carries no advantage and exposes them to harm. Biomarkers and machine-learning models show promise for future individualised risk assessment. Conclusions: Antithrombotic strategies post-TAVI should prioritise minimising bleeding while maintaining adequate thromboembolic protection. Single antiplatelet therapy for patients without an indication for OAC and OAC alone for those with AF offer the best balance of safety and efficacy. Ongoing trials may clarify the role of imaging-guided therapy and biomarker-based risk stratification and refine antithrombotic strategies. Full article

Background: Left Ventricle Myocardial Work (LVMW) has shown utility in assessing patients with aortic stenosis (AS) in recent studies. In the present study, we evaluated the predictive value and optimal cut-off values of LVMW parameters measured prior to TAVI that may be associated with increased mortality in AS patients. Methods: A total of 116 consecutive patients who were qualified for TAVI between March 2021 and November 2022 were evaluated. Pre-procedural LVMW indices (GWI, GCW, GWW, and GWE) were assessed and long-term survival was analysed. Survival and influencing factors were evaluated using univariate and multivariate Cox proportional hazard models, with significant factors subsequently included in cut-off analysis. Results: The median survival time following the TAVI procedure was 1404 (1143–1549) days, with a maximum observation period of 1721 days. All-cause mortality during the follow-up period reached 29%. Multivariate analysis revealed that EF, GLS, GWI, GWE and GCW before TAVI were independent predictors of all-cause mortality. We identified 1975 mmHg, 1497 mmHg and 85% as optimal cut-off values for GCW, GWI and GWE, which allow for significant stratification of patients according to risk. Conclusions: In this analysis, baseline-assessed parameters such as GLS, GWI, GWE, and GCW emerged as independent predictors of all-cause mortality. The proposed cut-off values clearly separated patient groups with different survival outcomes. Full article

Paravalvular leak (PVL) remains a clinically important complication after surgical or transcatheter valve implantation, presenting predominantly with heart failure (HF) and/or high-shear hemolysis. While redo surgery can be definitive, contemporary candidates frequently carry prohibitive operative risk, positioning transcatheter PVL closure as a key therapeutic alternative. However, available outcome data are largely derived from observational series and registries with heterogeneity in PVL mechanisms, prosthesis types, imaging protocols, and endpoint definitions. Standardized frameworks—such as those proposed by the PVL Academic Research Consortium—support harmonized PVL grading and clinically meaningful composite endpoints that integrate imaging/hemodynamic results with patient-centered outcomes. Across datasets, the most consistent determinant of benefit is residual PVL severity: procedural efficacy is most commonly defined as achieving ≤ mild residual regurgitation without prosthetic leaflet interference, device embolization, or major complications. This review provides a step-by-step, phenotype-driven approach to transcatheter PVL closure, emphasizing multimodality imaging (TEE and cardiac CT, with adjunct CMR and PET when appropriate), access and support planning tailored to valve position, and morphology-matched device selection—often requiring modular multi-device strategies for elongated crescentic channels, particularly in hemolysis-predominant presentations. We also synthesize evidence on complications and bailout management, with a focus on preventable high-severity events (leaflet impingement, embolization, stroke/air, vascular injury, tamponade) and standardized pre-release safety checks. Collectively, contemporary practice supports high implant success in experienced programs, with clinical improvement tightly coupled to procedural endpoint quality and careful Heart Team selection.

Objectives: Systemic inflammation, malnutrition, and immune dysregulation have emerged as important determinants of long-term outcomes after transcatheter aortic valve implantation (TAVI). The C-reactive protein–albumin–lymphocyte (CALLY) index is a novel immunonutritional biomarker that integrates these pathophysiological domains; however, its prognostic value in TAVI patients has not yet been investigated. This study aimed to evaluate the association between the CALLY index and 1-year mortality after TAVI. Methods: This retrospective observational study included 532 consecutive patients who underwent TAVI at a tertiary-care center between 2014 and 2023. Baseline laboratory parameters were obtained before the procedure, and the CALLY index was calculated as (albumin × lymphocyte count)/(C-reactive protein × 10). The primary endpoint was 1-year mortality. Receiver operating characteristic (ROC) curve analysis was performed to assess the discriminative ability of the CALLY index and conventional surgical risk scores. Multivariable regression analyses were used to identify independent predictors of mortality. Results: During the 1-year follow-up period, 85 patients (15.9%) died. Patients who died had significantly lower baseline CALLY index values compared to survivors (p < 0.001). The CALLY index demonstrated good discriminative performance for 1-year mortality (AUC: 0.797), outperforming EuroSCORE II (AUC: 0.705) and the Society of Thoracic Surgeons (STS) score (AUC: 0.619). A CALLY cut-off value of 0.45, derived using Youden’s index, was associated with a more than threefold increased risk of mortality. In multivariable analysis, the CALLY index remained independently associated with 1-year mortality, along with EuroSCORE II and more than mild mitral regurgitation. Conclusions: The CALLY index is a strong and independent predictor of 1-year mortality after TAVI and provides incremental prognostic value beyond conventional surgical risk scores. Given its simplicity and reliance on routinely available laboratory parameters, the CALLY index may serve as a practical tool for long-term risk stratification in patients undergoing TAVI.

Symptomatic severe aortic stenosis has an extremely high risk of death, ranging from 60 to 90% at five years if left untreated. This has informed the recommendation for urgent intervention upon diagnosis, especially when symptoms develop. Asymptomatic severe aortic stenosis has a four-year mortality between 30 and 50% if left untreated, which is similar to some metastatic cancers. Conservative management for patients with severe asymptomatic aortic stenosis was previously advocated, likely owing to the relative invasiveness of surgical aortic valve replacement. The advent of low-risk transcatheter aortic valve implantation with good medium-term durability has prioritized the need for a paradigm shift in the treatment of asymptomatic severe aortic stenosis towards a more proactive strategy of early intervention to reduce significant adverse events. This article provides a state-of-the-art overview of the contemporary management of patients with asymptomatic severe aortic stenosis. Full article

Background and Objectives: Transcatheter aortic valve implantation (TAVI) has become the mainstay of treatment for symptomatic aortic stenosis (AS) in patients over 70 years of age. It is also indicated for younger patients with significant comorbidities, for valve-in-valve interventions, and in selected patients with severe aortic insufficiency. We aimed to evaluate procedural and clinical outcomes of transfemoral TAVI performed over the course of 12 years by the same operators using different bioprosthetic valves. Materials and Methods: Between 2012 and 2023, 375 patients underwent TAVI in our clinic, with six types of bioprosthetic valves (Edwards Sapien XT, Medtronic Valves [CoreValve and Evolut R], Portico, Myval, Acurate Neo, and Direct Flow Medical). A transfemoral approach was used in all patients. The procedural and clinical outcomes were defined according to Valve Academic Research Consortium-3 (VARC-3) criteria. Results: The mean age of the patients was 78.4 ± 7.3, and their median STS score was 4.2 (2.9–5.9). Of the 375 patients, 361 had severe AS, 4 had severe aortic insufficiency, 5 were valve-in-valve, and 5 were valve-in-TAVI. Seven patients required a second valve implantation: four due to embolization of the prosthetic valve and three due to deep implantation of the prosthetic valve. Based on the VARC-3 criteria, the rates of technical success and device success were 90.4% and 85.3%, respectively. Major vascular complications were observed in 18 (4.8%) patients. Also, 42 (11.2%) patients required permanent pacemaker implantation. The incidence of moderate or worse paravalvular leak was 2.9%. The peri-procedural, 30-day, 1-year, and 5-year mortality rates were 5.1%, 4.3%, 15.2%, and 45.6%, respectively. STS scores (HR:1.129, 95%CI: 1.068–1.192, p < 0.001) and post-TAVI acute kidney injury (HR:3.993, 95%CI:1.629–9.785, p = 0.002) were detected as independent predictors of mortality in Cox regression analysis. Conclusions: This registry demonstrated the evolution of TAVI procedures at a single center over 12 years. A high level of collaboration between experienced operators and innovations in devices seem to be the key features for achieving high procedural success and low complication rates. Full article

Background: Sodium–glucose cotransporter 2 inhibitors (SGLT2 inhibitors), initially developed for glycemic control in type 2 diabetes, have demonstrated robust cardiovascular and renal benefits. Emerging evidence suggests that these agents may also affect valvular pathobiology, particularly in degenerative aortic stenosis (AS), through anti-inflammatory and antifibrotic mechanisms. Objectives: This study evaluated whether SGLT2 inhibitor use is associated with improved clinical outcomes in degenerative AS, including all-cause mortality and the need for SAVR or TAVR, recognizing that these endpoints represent surrogate rather than direct measures of valve hemodynamic progression. Methods: A retrospective cohort analysis was conducted using TriNetX, a federated electronic medical record-based research network. Diagnoses are captured using ICD-9/ICD-10-CM codes and medications using ATC codes. Adults with non-rheumatic AS were stratified by SGLT2 inhibitors use. Propensity score matching (1:1) was performed to balance baseline characteristics between treated and untreated groups (n = 10,912 per group). Primary outcomes included all-cause mortality, TAVR, and SAVR during follow-up. Echocardiographic parameters (AVA, Vmax, mean gradient) were not systematically available. Results: After adjustment for comorbidities, SGLT2 inhibitor use was independently associated with lower all-cause mortality (6.15% vs. 9.34% HR 0.595; 95% CI 0.552–0.641; p < 0.001), TAVR (2.81% vs. 2.89% HR 0.835; 95% CI 0.746–0.934; p = 0.002), SAVR (1.28% vs. 1.90% HR 0.514; 95% CI 0.442–0.599; p < 0.001), cardiac arrest (0.82% vs. 1.21% HR 0.71; 95% CI 0.582–0.867; p < 0.001), and end-stage kidney disease (0.40% vs. 1.0% HR 0.292; 95% CI 0.222–0.384; p < 0.001). Although these associations may suggest slower disease progression, interpretation is limited by the lack of systematic echocardiographic follow-up. Conclusions: In addition to their established benefits in heart failure and renal protection, SGLT2 inhibitors may have valve-preserving effects in degenerative AS. Because true hemodynamic progression could not be evaluated, these results should be viewed as associations with surrogate clinical endpoints. Prospective studies with standardized imaging are required to determine whether SGLT2 inhibition can directly alter the course of this currently untreatable disease Full article
