Background: Ventricular septal defects (VSD) are the most common form of congenital heart disease (CHD). Current guidelines recommend surveillance transthoracic echocardiograms (TTE) following surgical closure of perimembranous VSDs (pVSD); however, duration of screening is not explicitly stated. The goal of this study is to determine the utility of follow-up TTEs after uncomplicated pVSD surgical closure. Methods: Single-site retrospective analysis was conducted on patients who underwent pVSD surgical closure. Patients were excluded if diagnosed with other CHD, had complications 1 year post-repair, or lacked data 1 year post-repair. Serial TTEs were reviewed. A Kaplan–Meier curve was used to illustrate the 5-year complication-free survival. Results: A total of 117 patients met inclusion criteria. A 97% 5-year complication-free survival was observed. Four patients had complications >1 year post-repair: one non-obstructive subaortic ridge, one pulmonary vein stenosis, one pinhole residual pVSD, and one ventricular ectopy with ventricular dysfunction. Of the 113 complication-free patients, 197 TTEs were performed with no change in clinical management. Conclusions: Beyond 1 year post-repair, the occurrence of new complications following uncomplicated pVSD surgical closure is rare. Unless clinical concerns arise, the utility of routine TTEs > 1 year post-repair in this uncomplicated post-surgical cohort should be reassessed. Larger multicenter studies are needed to determine the utility of routine TTEs. Full article

Background: Post-COVID-19 condition (PCC) is a complication following acute COVID-19 infection, which may lead to long-term cardiac abnormalities. This review aimed to assess the prevalence of structural/functional deviations in echocardiography in individuals with PCC compared to patients without PCC. Methods: We searched three databases. Two reviewers independently screened articles using LASER Al and extracted relevant data using a piloted Excel sheet. We performed meta-analysis using OpenMeta and RevManWeb and a subgroup analysis based on patients’ settings during acute COVID-19. We assessed the risk of bias using the Hoy et al. tool and the certainty using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results: We included 16 studies that reported on differences in echocardiographic findings in patients with or without PCC. Individuals with PCC were more likely to have structural/functional deviations in echocardiographic readings of unclear clinical significance, particularly those who were hospitalized during acute COVID-19. The overall certainty of the evidence was very low due to the high risk of bias, indirectness, and imprecision. Conclusions: This review provides insight into the use of echocardiograms and the frequency of test deviations in individuals with PCC. Despite existing evidence, there is a need for future studies to assess the diagnostic test accuracy of echocardiograms in PCC. Full article

Background: Autoimmune rheumatic diseases (ARDs) often present diagnostic challenges, particularly in undifferentiated disease or overlap syndromes. Autoantibodies (AABs) serve as early biomarkers, but their relationship with cardiac involvement during the prodromal phase remains unclear. We hypothesized that cardiac involvement is an early, unifying feature in AAB-seropositive patients with suspected ARD/overlap syndromes but an as-of-yet unclear diagnosis. Methods: We prospectively recruited 18 treatment-naïve patients (mean age 52 ± 17 years, 94.4% women) with suspected undifferentiated ARD/overlap syndromes who were seropositive for myositis-specific (MSAs), myositis-associated (MAAs), or scleroderma-specific autoantibodies (SScSAs). All underwent comprehensive rheumatologic, pulmonologic, and cardiac evaluations, including multiparametric cardiovascular magnetic resonance (CMR) to assess myocardial inflammation, edema, and fibrosis. Results: Despite normal echocardiograms, electrocardiograms, and inflammatory biomarkers, all patients exhibited CMR evidence of cardiac involvement. Active myocardial inflammation (revised Lake Louise criteria) was confirmed in 66.7%, while subepicardial fibrosis was universal (median 5.0% of LV mass). During the 12-month follow-up, all patients with evidence of inflammation received immunosuppressive and cardioprotective therapy, leading to symptomatic improvement in all and reduced inflammation in 75% of repeat CMRs (3/4 patients). A definitive rheumatologic diagnosis was established in all cases, with 50% classified as overlap syndromes. Conclusions: Cardiac involvement is a highly prevalent disease manifestation in AAB-seropositive patients with suspected ARD/overlap syndromes and can be detected by CMR during the prodromal phase, even before diagnostic criteria are met. These findings support early CMR integration in the workup of such patients to guide timely immunosuppressive and cardioprotective interventions. Full article

Septic cardiomyopathy is recognized as an acute, transient, and reversible condition. However, septic insult may induce latent changes characteristic of cardiac remodeling, with future consequences. Therefore, the present study aimed to evaluate the morphological and functional cardiac changes in the acute and subacute phases (with 7-day follow-up) in male Wistar rats subjected to experimental sepsis using a cecal ligation and puncture (CLP) model. In the acute phase, the animals underwent echocardiographic assessment at baseline and 48 h after the induction of sepsis. In the subacute 7 days follow-up, animals were allocated in control and sepsis groups. After this period, the animals underwent echocardiographic assessment, followed by euthanasia, papillary muscle testing, and subsequent morphometric and biochemical analyses. Fecal samples from six animals per group were collected at baseline and after 7 days for microbiota analysis. In the acute phase, echocardiographic assessment revealed that, following sepsis, animals exhibited reduced systolic function. In the subacute 7 days follow-up, both echocardiogram and papillary muscles revealed cardiac dysfunction in the sepsis group. Cardiomyocyte cross-sectional area and collagen content were significantly greater in the sepsis group compared with that in the control group. Analysis of maximal enzymatic activities involved in cardiac energy metabolism and oxidative stress biomarkers revealed no significant differences between groups. Considering microbiota assessment, beta diversity analysis revealed significant differences between septic animals and controls. In conclusion, sepsis was associated with persistent systolic/diastolic dysfunction, cardiomyocyte hypertrophy, and fibrosis after 7 days. These data suggest that septic cardiomyopathy should not be considered merely an acute, transient, and reversible condition in this experimental context. Full article

Long-term transthoracic echocardiogram (TTE) follow-up guidelines after muscular ventricular septal defect (mVSD) device closure are vague. The primary goal of this study was to perform a literature search to characterize the type and timing of complications that occur after mVSD device placement. The search was performed in Medline (PubMed) with English language and publication date (1983 to 2024) filters applied. Studies were included if they reported on patients who underwent mVSD device closure. Studies were excluded if they reported on other types of ventricular septal defect (VSD) device closures, were review papers, or did not report outcomes after the device procedure. A total of 139 articles met the criteria (retrospective, n = 63; prospective, n = 10; case reports, n = 66), encompassing 1668 patient cases. Age at the time of mVSD closure was 10.6 + 2.7 years. Incidence of complications was 17.9% (299/1668). Maximum follow-up was 160 months. Most complications were residual shunts (40.8%, 122/299), followed by valve dysfunction (13.7%, 41/299) and arrhythmias (13.7% 41/299). The vast majority of complications occurred ≤12 months post-device placement 98.0% (293/299). Only 1.3% (4/299) of complications occurred at >12 months (mild tricuspid regurgitation, n = 2; left bundle branch block, n = 1; atrial fibrillation, n = 1). Time until complication was not reported in 0.7% (2/299) of patients (residual shunts, n = 2). All clinically significant complications diagnosed via TTE occurred <12 months post-mVSD device procedure. The utility of repeat TTE beyond one year after mVSD device closure should be reassessed if no clinical concerns are present. Full article

Introduction: Primary Sjögren’s (pSS) is an autoimmune disease that affects several organs, especially the heart, and raises cardiovascular risk. Investigating the associations of hemoglobin-to-red cell distribution width (RDW) ratio (HRR), vitamin D status, and cardiac function could provide valuable insights and biomarkers regarding early cardiovascular risk in patients with pSS. Method: This cross-sectional study involved 61 patients diagnosed with pSS based on ACR/EULAR criteria. Data on demographics, hematological (Hb, RDW), echocardiography, and serum vitamin D levels were collected. Echocardiograms were conducted by trained cardiologists following established guidelines, while vitamin D levels were measured using ELISA. Statistical analyses, including univariate linear regression, were performed with SPSS in order to identify whether HRR tertiles were related to cardiac function and vitamin D status. Results: A study of 61 pSS patients (mean age 59.8 years, 89% female) revealed that patients with a lower hemoglobin-to-RDW ratio (HRR ≤ 0.98) had significantly higher pulmonary artery pressures (PAPs) and lower values for the tricuspid annular plane systolic excursion (TAPSE)/PAPs ratio, contributing to poor right heart function. These associations were particularly strong in patients with insufficient levels of vitamin D (<30 ng/mL), while differences in other echocardiographic parameters remained nonsignificant between HRR groups. Conclusions: These findings underscore the clinical value of HRR as a composite biomarker that reflects the interplay between anemia, inflammation, and cardiovascular health in primary Sjögren’s disease. They also suggest that vitamin D status may be an important therapeutic consideration to mitigate cardiopulmonary risks in this population. Full article

Background: Atrial fibrillation (AF) is a common tachyarrhythmia associated with increased morbidity. AF frequently occurs alongside mitral regurgitation (MR). Although the impact of MR severity on AF is well proven, its effect on AF recurrence post-ablation is unclear and was the focus of our study. Methods: Retrospective single-center cohort of patients who underwent AF catheter ablation from 2014 to 2024. Pre-procedural transthoracic echocardiograms evaluated pre-ablation baseline MR severity. Patients with ‘significant’ MR (defined as moderate–severe or severe MR) were compared to those with ‘non-significant’ MR. Univariate Kaplan–Meier (KM) survival analysis, multivariable Cox proportional hazards models, and inverse probability treatment weighting (IPTW) method were applied to assess the association between baseline MR and AF recurrence post-ablation. Results: Among 444 patients undergoing AF ablation, 28 (6.3%) had ‘significant’ baseline MR. Over median follow-up of 19 months, 104 (23.4%) patients experienced AF recurrence. Univariate and KM survival analyses showed a non-significant trend for increased AF recurrence among patients with ‘significant’ MR. Applying KM analysis on balanced IPTW pseudo-population revealed robust association between ‘significant’ MR and AF recurrence post-ablation (HR = 2.41, 95% CI 1.80–3.22, p < 0.001). Multivariate analysis, performed on IPTW-adjusted pseudo-population, including age, gender, LA diameter, LVEF, and AF type, showed ‘significant’ MR to be independently associated with AF recurrence post-ablation (HR = 2.11, 95% CI 1.43–5.73, p = 0.003). Conclusions: Use of IPTW pseudo-population suggests a significant association between baseline MR severity, regardless of its etiology, and AF recurrence post-ablation. This association should be confirmed by future larger studies. Full article

Background/Objectives: Cardiac allograft vasculopathy (CAV) remains a prevalent and serious long-term complication following orthotopic heart transplantation (OHT), contributing substantially to graft failure and patient mortality. Given the adverse prognostic impact of extensive coronary artery involvement, this study investigates whether myocardial work (MW) indices can serve as a non-invasive tool to detect OHT recipients with a high burden of coronary disease. Methods: In this prospective study, 55 OHT recipients underwent paired evaluations with coronary computed tomography angiography (CCTA) and transthoracic echocardiography (TTE) during routine follow-up. From the echocardiograms, global longitudinal strain (GLS) of the left ventricle (LV) and myocardial work (MW) indices were derived. Patients were classified into two groups according to CCTA findings: those without extensive coronary artery disease (disease affecting fewer than four coronary segments or none, OHT < 4) and those with extensive disease (disease of four or more coronary artery segments, OHT ≥ 4). Results: CCTA revealed extensive coronary disease in 38 OHT recipients, while 17 had involvement of fewer than four segments or none. Between-group comparisons showed significant differences in global wasted work (GWW, energy expended without generating forward flow) and global work efficiency (GWE, the percentage of constructive work relative to total work). Using the Youden Index, the optimal thresholds for identifying extensive disease were GWW > 88 mmHg% and GWE < 94%. Patients exceeding these thresholds had a markedly higher probability of having ≥ 4 affected segments, with ORs of 4.61 for pathological GWW and 3.68 for pathological GWE compared to those with normal values. Conclusions: GWW and GWE demonstrated the strongest performance for identifying OHT recipients with extensive coronary disease. If confirmed in larger cohorts, these indices could offer a practical, non-invasive approach for detecting extensive CAV. Full article

Amyloidosis is characterized by the tissue deposition of insoluble fibrils derived from misfolded proteins. This case report describes a Hispanic man diagnosed with both monoclonal gammopathy of undetermined significance (MGUS) and wild-type transthyretin amyloidosis (ATTR) cardiac amyloidosis. The diagnosis was made using a combination of serological tests and multimodality cardiac imaging. The report highlights the importance of multimodality imaging in diagnosing cardiac amyloidosis, especially in cases where MGUS is also present. The patient presented with shortness of breath and was found to have cardiac abnormalities through electrocardiogram, echocardiogram, and cardiac magnetic resonance (CMR). A technetium-99m pyrophosphate (Tc-99m PYP) scan confirmed the presence of ATTR cardiac amyloidosis. Bone marrow biopsy confirmed MGUS. The patient was treated with diuretics and remained asymptomatic during follow-up. The report emphasizes the need for accurate diagnosis to differentiate between AL, ATTR, and MGUS due to their distinct clinical courses and treatments. Full article

Background and Clinical Significance: Mycotic aortic aneurysm is a rare but life-threatening vascular condition characterized by infection-induced dilation or pseudoaneurysm formation in the aorta. The condition carries a high risk of rupture and mortality, especially in individuals with underlying cardiovascular disease, who have undergone recent vascular procedures, or with immunocompromising comorbidities such as diabetes. Its diagnosis is challenging due to its non-specific symptoms and often requires a high index of suspicion, especially in patients presenting with persistent fever and negative initial imaging. Early recognition and intervention are critical, as delayed treatment significantly worsens outcomes. Case Presentation: A 68-year-old male with a history of coronary artery disease, recent stent placement, and hypertension presented with two days of fever, chills, rigors, and a mild nonproductive cough. The laboratory findings were only significant for leukocytosis. The initial chest X-ray and non-contrast CT scans were unremarkable. He was admitted for presumed pneumonia and started on intravenous antibiotics. Persistent fever prompted further investigation with contrast-enhanced CT, which revealed a distal-aortic-arch pseudoaneurysm and mild mediastinal stranding. Blood cultures grew methicillin-sensitive Staphylococcus aureus (MSSA). Transthoracic echocardiogram was negative for endocarditis. The patient was transferred to a tertiary center, where repeat imaging confirmed a 1.5 cm pseudoaneurysm and a 4 mm penetrating atherosclerotic ulcer. After multidisciplinary assessment, he underwent thoracic endovascular aortic repair (TEVAR) and completed four weeks of intravenous cefazolin. Follow-up imaging showed successful aneurysm repair with no complications. Conclusions: Thoracic mycotic aneurysm is a rapidly fatal entity despite intervention. High clinical suspicion is necessary given its non-specific presentation. It is diagnosed most practically using CTA. In addition to antibiotics, TEVAR is gaining traction as a feasible and a safe alternative to open surgical repair (OSR). Full article

Background: Treadmill exercise stress echocardiography (ESE) is both feasible and safe in the pediatric population. Although regional wall motion abnormalities (RWMAs) have limited diagnostic utility, Doppler studies frequently demonstrate significant intraventricular pressure gradients (IVPGs) during exercise. These IVPGs, which were observed in 39% of 258 previously studied adolescents, are absent at rest. Their detection provides valuable insight into exercise-related symptoms and abnormal findings on resting or stress electrocardiograms (ECGs). Purpose: To evaluate the effect of β-blocker therapy on the occurrence of intraventricular pressure gradients (IVPGs) in adolescents presenting with symptoms or abnormal findings on resting or stress electrocardiograms (ECGs). Methods: Exercise stress echocardiography (ESE) was repeated in 66 of 101 adolescents who were found to have developed intraventricular pressure gradients (IVPGs) during the initial assessment. All participants had normal resting echocardiograms, and all underwent follow-up evaluation while receiving β-blocker therapy. The study cohort included 15 females (23%) and the mean age of participants was 14.6 ± 1.7 years (range: 11–17 years). Comprehensive two-dimensional and Doppler echocardiographic assessments were performed at baseline and during β-blocker treatment. Results: During the initial ESE, the mean intraventricular pressure gradient (IVPG) was 105 ± 38 mmHg. Under β-blocker therapy, 37 adolescents no longer developed IVPGs while, in the remaining 29 adolescents, the IVPG was significantly reduced to a mean of 58 ± 32 mmHg (p < 0.0001). The mean heart rate at peak exercise decreased from 178 ± 15 bpm at baseline to 157 ± 9 bpm during the repeat ESE under β-blocker treatment (p < 0.0001). Clinical symptoms were reproduced in forty-seven adolescents during the initial ESE, but occurred in only seven adolescents during treatment (p < 0.0001). Conclusions: In adolescents presenting with symptoms or abnormal resting or stress ECG findings, and exertional intraventricular pressure gradients (IVPGs), oral β-blocker therapy either prevented the occurrence of IVPGs or significantly reduced their severity. These hemodynamic improvements were associated with the resolution of clinical symptoms in 85% of the symptomatic cohort. Full article

Objective: The association between right ventricular myocardial fiber deformation and nutrition in weightlifters has not been fully characterized. This study analyzed nutritional factors and right ventricle speckle tracking echocardiography parameters in weightlifters before and after bench press exercises. Methods: This interventional study examined the effects of bench press exercises on myocardial function. Nutritional parameters were assessed prior to exercise. Echocardiography with speckle tracking using vector velocity analysis was performed before and immediately after the bench press exercise. This study included a group of non-elite athlete weightlifters and a non-athlete control group to compare right myocardial function. In the athlete group, transthoracic echocardiograms (TTEs) were conducted before and after the exercise to assess changes in systolic and diastolic right heart function. A cohort of 30 weightlifters from 2014 who continued regular training was re-evaluated in 2024, and nutritional data were collected. Data analyses included ANOVA and Student’s T-tests, and correlation coefficients were calculated to explore associations with speckle tracking results. Results: This study involved 211 male weightlifters and a control group of 60 non-athletes. Measured values for the control group and athletes before and after bench press exercise were as follows: right longitudinal global strain (−27.31 ± 1.47, −23.55 ± 2.37, −30.98 ± 2.12); right global longitudinal strain rate (−1.79 ± 0.078, −1.48 ± 0.33, −2.88 ± 0.259 1/s), all p < 0.001; and isovolumic acceleration (2.38 ± 0.22, 3.52 ± 0.15, 6.66 ± 0.88 m/s², p < 0.001). Following exercise, right intraventricular synchrony increased, and longitudinal strain delay decreased (144.88 ± 22.52, 168.92 ± 29.35, 98.27 ± 12.11 ms, p < 0.001). The follow-up group demonstrated a similar response to exercise as the other weightlifters. Right ventricular longitudinal strain showed correlations with protein, vitamin E, and zinc levels (R² = 0.399, p = 0.021; R² = 0.378, p = 0.03; R² = 0.566, p < 0.01), and right ventricular radial velocities correlated with group B vitamins. Conclusions: Weightlifters show less right ventricular deformity before exercise compared to controls, but their strain increases significantly post-exercise. Speckle tracking values might correlate with nutrition. Full article

The mitral valve is the most susceptible to pathological alterations, such as mitral stenosis, characterized by failure of the valve to open completely. In this context, the objective of this study was to apply digital image processing (DIP) and develop a convolutional neural network (CNN) to provide decision support for specialists in the diagnosis of mitral stenosis based on transesophageal echocardiography examinations. The following procedures were implemented: acquisition of echocardiogram exams; application of DIP; use of augmentation techniques; and development of a CNN. The DIP classified 26.7% cases without stenosis, 26.7% with mild stenosis, 13.3% with moderate stenosis, and 33.3% with severe stenosis. A CNN was initially developed to classify videos into those four categories. However, the number of acquired exams was insufficient to effectively train the model for this purpose. So, the final model was trained to differentiate between videos with or without stenosis, achieving an accuracy of 92% with a loss of 0.26. The results demonstrate that both DIP and CNN are effective in distinguishing between cases with and without stenosis. Moreover, DIP was capable of classifying varying degrees of stenosis severity—mild, moderate, and severe—highlighting its potential as a valuable tool in clinical decision support. Full article

Parvovirus B19 (B19V) re-emerged across Europe in 2024, raising concerns about vertical transmission and neonatal morbidity. We undertook a prospective, single-centre cohort study to characterise the early clinical course of congenitally infected neonates born between April and December 2024. Seventy-one pregnancies with serologically or PCR-confirmed maternal infection were enrolled; seven neonates met laboratory criteria for congenital B19V infection and were followed with serial clinical, biochemical and imaging assessments through the first year of life. Troponin I and CK-MB were measured on days 1, 3, 7 and 15; electrocardiogram (ECG) and echocardiography were repeated in parallel, and cranial ultrasound (US), ophthalmologic and audiologic screening were scheduled prospectively. Mean troponin rose from 50.7 ng L⁻¹ on day 1 to a peak of 120.7 ng L⁻¹ on day 7 (p < 0.01), normalising by one month, while echocardiograms remained structurally normal, and only one transient arrhythmia was recorded. CK-MB exceeded the reference range in 29% of infants but showed no clinical sequelae. Multiple periventricular hyperechogenicities were identified in 8/70 neonates (11%), and moderate anaemia (Hb ≤ 9.8 g/dL) occurred in 2 cases. Serum PCR detected high-level viraemia (>10⁸ genome equivalents mL⁻¹) in 40% of those tested; saliva and urine were consistently negative. No instances of myocarditis or hydrops were observed. Our findings indicate that congenital B19V infection during the current outbreak is marked by transient biochemical myocardial stress and subtle neurosonographic changes rather than overt cardiac disease, supporting an outpatient-focused follow-up strategy incorporating serial biomarkers and targeted neuroimaging.

Background: The Da Silva Cone procedure for Ebstein anomaly has dramatically improved tricuspid valve competence and clinical outcomes. However, preoperative left ventricular (LV) dysfunction and immediate postoperative right ventricular (RV) systolic dysfunction are frequently observed. While excellent valve outcomes are well established, recovery of biventricular function following the Cone remains less defined. This study aimed to evaluate longitudinal changes in RV and LV function postoperatively and over a minimum of six months post-Cone operation. Methods: A single center retrospective review of 134 patients who underwent Cone repair for Ebstein’s anomaly from 2016 to 2024 was performed. Echocardiograms were analyzed at three time points: preoperative (Time 1), hospital discharge (Time 2), and ≥6 months postoperative (Time 3). RV parameters included fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), and tricuspid S′. LV parameters included left ventricular ejection fraction (LVEF), end-diastolic volume indexed to body surface area (LVEDVi), left ventricular stroke volume (LVSVi), and mitral E/E′. Subgroup analyses examined outcomes by prior Glenn, Starnes procedure, and degree of RV dilation. Paired two sample t-tests were used to compare serial measures. Results: Median age at surgery was 7.8 years (IQR: 2.3–17.7). All patients had discharge echocardiograms; 70 had follow-up studies at ≥6 months. RV function declined postoperatively with reductions in FAC (35% to 21%), TAPSE (2.0 to 0.8 cm), and S′ (13 to 5 cm/s), all p < 0.001. By Time 3, these measures improved (FAC to 29%, TAPSE to 1.3 cm, S′ to 7 cm/s) but did not fully return to baseline. LVEDVi and LVSVi increased significantly by Time 3 (LVEDVi: 47 to 54 mL/m²; LVSVi: 30 to 34 mL/m²; p < 0.001), while LVEF remained unchanged. Patients with prior Glenn or Starnes had greater Time 1 LV volumes and lower RV function, but by Time 3, most differences resolved. Moderate–severe preoperative RV dilation was associated with worse RV function at Time 2 and normalized by Time 3. Conclusions: The Da Silva Cone procedure leads to early postoperative RV dysfunction with partial recovery over the mid-term follow-up. Concurrently, LV filling and stroke volume improve, reflecting favorable interventricular interaction. These findings support echocardiographic surveillance to guide functional recovery post-Cone and inform patient counseling. Full article
