(1) The aim of the study was to reveal what differences in patients’ lipidogram, oxidative stress, and echocardiographic readings are reflected by SII, SIRI, and MHR of the patients with chronic heart failure (CHF). (2) A total of 220 patients diagnosed with CHF were investigated. They were stratified into groups according to averages of SII (neutrophil * platelet/lymphocyte count), SII ≤ 684.757 (n = 115), and SII > 684.757 (n = 62); SIRI (neutrophil * monocyte/lymphocyte count), SIRI ≤ 2.098 (n = 110), SIRI > 2.098 (n = 67); and monocyte count/high-density lipoprotein cholesterol concentration (MHR), MHR ≤ 0.5854 (n = 54), and MHR > 0.5854 (n = 64) values. The analysis of transthoracic echocardiogram, complete blood count test, C reactive protein, lipidogram, oxHDL, nitrotirozine, ditirozine, TAC, protein carbonyl, catalase, and MDA were performed; (3) Between the groups, according to SII and SIRI, there were no statistically significant differences in lipidogram, oxidative stress, and echocardiography readings. In those with higher MHR, HDL concentration was lower (0.91 (0.44; 1.45) and 1.27 (0.72; 2.69), p < 0.001). In those with higher MHR, LVEDD was higher (58.12 (10.03) and 51.53 (10.34), p < 0.001), LVMM was higher (274.92 (92.24) and 233.07 (74.84), p = 0.010), MMI was higher (130.88 (34.28; 227.97) and 114.27 (70.34; 270.00), p = 0.022), and LVEF was lower (28.5 (10.0; 55.0) and 40.0 (20.0; 55.0), p < 0.001). MHR correlated with MMI (r = 0.287, p = 0.028) and LVMI (r = 0.287, p = 0.028). Nitrotyrosine concentration was higher in those with higher MHR (4.52 (1.12; 93.58) and 3.52 (1.74; 28.32), p = 0.022). MHR correlated with protein carbonyl (r = 0.321, p = 0.013), nitrotyrosine concentration (r = 0.356, p = 0.006). SIRI correlated with carbonyl protein concentration (r = 0.321, p = 0.013); (4) 1. In CHF patients, MHR could reflect the worsening of patients’ conditions related to oxidative stress. 2. The possibility to use SII and SIRI still needs to be confirmed. Full article

Background: Patients with heterozygous familial hypercholesterolemia (HeFH) are at a high risk of atherosclerotic cardiovascular disease. The coronary artery calcification (CAC) score by the Ct-scan Agatston calcium score (ACS) > 100 classifies FH at a higher risk. The echocardiographic calcium score (ECS) evaluates aortic valve calcifications and is considered a good predictor of the atherosclerotic burden and cardiovascular outcome. Objective: To test the ECS as a predictor of ACS > 100 in a HeFH cohort. Methods: A coronary calcium CT scan with the calculation of ACS and an at rest-transthoracic echocardiogram with ECS evaluation were performed in 81 HeFH patients. Patients were divided into two groups according to the ACS: high-risk ACS patients (High-ACS) with Agatston value > 100 and low risk ACS patients (Low-ACS) with Agatston value ≤ 100. Patients were stratified according to ECS = 0 or ECS > 0. Results: High-ACS patients were older than Low-ACS patients; BMI, waist circumference, and blood systolic pressure were significantly higher (p < 0.001) in High-ACS patients. The ECS predicted an ACS > 100 with sensitivity = 0.84, specificity = 0.89, accuracy = 0.86, and precision = 0.76. Conclusions: The ECS could be a good surrogate of a coronary calcium CT scan for ACS evaluation in the specific subset of HeFH patients. Full article

Acute aortic dissection (AAD) is a critical cardiovascular emergency marked by the rupture of the aortic intima, resulting in blood infiltration into the media and the formation of a false lumen. AAD incidence varies by area, emphasizing the need for better diagnostics and epidemiological investigations. Bucharest University Emergency Hospital’s Emergency Department conducted this retrospective cohort analysis from May 2021 to May 2023. We examined 26 Stanford Type A aortic dissection patients to establish in-hospital mortality and one-year survival rates. The primary objective was to analyze demographic, clinical, and paraclinical factors and their impact on patient outcomes. A total of 57.7% of the study group was male and had a mean age of 58.2 years, and 69.2% of patients had hypertension, indicating its importance as a risk factor. Acute chest discomfort was reported by 53.8%, neurological problems by 30.8%, and syncope or hypotension by 42.3%. CT angiography and transthoracic echocardiogram (TTE) confirmed the diagnosis and assessed dissection severity. Pericardial effusion (19.2%) and moderate to severe aortic regurgitation (26.9%) were notable. Management varied by dissection intensity and location. Emergency surgery was performed in 61.5% of patients within 24 h of diagnosis, resulting in a 12.5% in-hospital death rate. Conservatively managed patients had a 60.0% in-hospital death rate. Timely intervention is crucial, since the surgical cohort had an 87.5% one-year survival rate compared to 30% for the conservatively managed cohort. Acute renal damage (25%), protracted mechanical ventilation (31.3%), and advanced supportive care infections were postoperative sequelae. Conservative care exacerbated visceral ischemia (20%) and heart failure (10%). Advanced age and hypotension upon admission were independent mortality predictors, emphasizing the need for early risk assessment and personalized treatment. Multimodal imaging, timely surgical referral, and excellent postoperative care improve AAD outcomes, according to this study. Full article

Background and Clinical Significance: Cardiac sarcoidosis (CS) is a rare but life-threatening disorder, occurring in 2–5% of sarcoidosis cases, though post-mortem studies suggest a higher prevalence. It presents diagnostic challenges due to nonspecific symptoms and the low sensitivity of an endomyocardial biopsy. Recent guidelines emphasize multimodal imaging, such as cardiac magnetic resonance imaging (MRI) and positron emission tomography (PET). Given the risk of heart failure (HF) and arrhythmias, early detection is critical. This case highlights the role of non-invasive imaging in diagnosing CS and guiding treatment. Case Presentation: A 54-year-old female with asthma, hyperlipidemia, a recent diagnosis of anterior uveitis, and familial sarcoidosis presented with dyspnea, chest tightness, and worsening cough. Examination revealed anterior uveitis, erythema nodosum, jugular venous distension, and pedal edema. The electrocardiogram (ECG) demonstrated bifascicular block and premature ventricular contractions (PVCs). The brain natriuretic peptide (BNP) was 975 pg/mL, with the transthoracic echocardiogram revealing a left ventricular ejection fraction of 25–30% with global LV akinesis. Coronary computed tomography angiography (CCTA) excluded coronary artery disease. Cardiac MRI showed late gadolinium enhancement, with PET demonstrating active myocardial inflammation, supporting a >90% probability of CS. Given her clinical trajectory and risk of further decompensation, immunosuppressive therapy was initiated without pursuing a biopsy. A dual-chamber implantable cardioverter defibrillator (ICD) was placed due to risk of ventricular arrhythmias. Bronchoalveolar lavage (BAL) showed a CD4/CD8 ratio of 6.53, reinforcing the diagnosis. She responded well to treatment, with symptom improvement and repeat imaging demonstrating signs of disease remission. Conclusions: This case underscores the growing role of multimodal imaging in CS diagnosis, potentially replacing biopsy in select cases. Early imaging-based diagnosis enabled timely immunosuppression and ICD placement, improving outcomes. Full article

Atrial fibrillation (AF) is a supraventricular arrhythmia and the most common heart rhythm disorder in the adult population worldwide with an estimated prevalence of 2% to 4% of the population. Cases of AF have shown an increasing trend in recent decades, while its frequency is expected to rise even more. Given the significant impact on patients’ quality of life, as well as its major complications, including thromboembolic events, effective rhythm control strategies other than antiarrhythmic medication have emerged, with catheter ablation (CA) being the cornerstone of these. In recent years, CA has been upgraded to a first-line treatment for selected patients. However, complications do exist and arrhythmia-free survival is not always guaranteed. The need to better identify patients more suitable for this specific therapeutic measure is crucial in improving outcomes and preventing arrhythmia recurrences. This review aims to present currently identified predictors of AF recurrence after catheter ablation based on clinical characteristics and electrocardiographic and echocardiographic parameters, in an era of increasing interventional rhythm control approaches for the management of atrial fibrillation.

The combination of hypertrophic cardiomyopathy with outflow tract obstruction, severe pre-capillary and post-capillary pulmonary hypertension, and severe primary mitral regurgitation is rare and presents distinct management challenges. Background and Clinical Significance: Pulmonary hypertension is an independent predictor of all-cause mortality in patients with hypertrophic cardiomyopathy managed medically and often precludes patients from undergoing cardiopulmonary bypass due to increased surgical morbidity and mortality. In studies specifically evaluating surgical myectomy, however, survival is favorable in patients with moderate-to-severe pulmonary hypertension. Case Presentation: We present a case of a 74-year-old male with six months of dyspnea with minimal exertion. A diagnostic work-up with transthoracic echocardiogram showed asymmetric left ventricular hypertrophy, left ventricular outflow tract obstruction with a peak gradient of 200 mmHg, right ventricular systolic pressure of 99 mmHg, systolic anterior motion of the mitral valve and flail anterior mitral leaflet. The patient was evaluated by a multi-disciplinary team and underwent extended septal myectomy and mitral valve repair with significant improvement in functional capacity post-operatively. Conclusions: While pulmonary hypertension increases the risk of morbidity and mortality during cardiopulmonary bypass, moderate-to-severe pulmonary hypertension in hypertrophic cardiomyopathy with outflow tract obstruction is a unique indication for septal reduction therapy that may not be associated with higher surgical mortality.

Background and Objectives: Resistance exercises (REs) are a type of physical activity that individuals from many age groups have been doing recreationally, both as amateurs and professionally, in their daily lives in recent years. It is crucial to understand the effects of such sports on cardiac morphology in order to maximize the benefit of training and to tailor the training content accordingly. The aim of this study was to investigate the relationship between training experience (TE) and left ventricular (LV) systolic and diastolic parameters and left atrial (LA) mechanical function in healthy subjects who regularly performed RE for different durations. Materials and Methods: Forty-five healthy adults [age = 28.91 ± 10.30 years, height = 178.37 ± 5.49 cm, weight = 83.15 ± 13.91 kg, body mass index = 26.03 ± 3.42 kg/m², TE = 7.28 ± 6.49 years] who performed RE between 1 year and 20 years were included in our study. The transthoracic echocardiograms (ECHOs) of the participants were evaluated by the cross-sectional research method, which is often used to understand the current situation in a given time period. Correlations between TE and LV systolic and diastolic parameters and LA mechanical function were analyzed. Results: As a result, interventricular septal thickness (IVS; r = 0.33, p = 0.028), the aortic diameter systole (ADs; r = 0.56, p < 0.001), and aortic diameter diastole (ADd; r = 0.58, p < 0.001) were positively correlated with TE, indicating associations with increased left ventricular (LV) hypertrophy and reduced ventricular compliance, while the aortic strain (AS; r = −0.44, p = 0.002), aortic distensibility (AD; r = −0.62, p < 0.001), and diastolic flow parameters including E (r = −0.41, p = 0.005), E/A (r = −0.38, p = 0.011), and E/Em (r = −0.31, p = 0.041) were negatively correlated with TE, reflecting impairments in diastolic function. Conclusions: This study showed that diastolic parameters were adversely affected in chronic RE. Therefore, we think that these individuals may have decreased relaxation and filling functions of the heart, which may also reduce adequate oxygen and nutrient delivery to the tissues. In this context, cohort studies are needed to analyze in detail the reasons for the decrease in diastolic parameters in these individuals. Full article

Introduction: Infectious catheter-related right atrial thrombus (CRAT) is a potentially fatal but often underestimated contingency associated with central venous catheter (CVC) in patients on hemodialysis. Management guidelines for CRAT are lacking, and its occurrence poses clinical challenges. Here, we describe the case of an infectious CRAT in a young patient on hemodialysis with peculiar clinical complications and perform a literature review. Case presentation and literature review: A 30-year-old man on hemodialysis after bilateral nephrectomy due to polycystic disease presented with hyperpyrexia resistant to broad-spectrum antibiotics. A pleural empyema caused by methicillin-resistant Staphylococcus aureus (MRSA) was diagnosed. Since fever persisted despite targeted antibiotic therapy, a transthoracic echocardiogram to exclude infective endocarditis was performed, showing a right atrial thrombus. CVC was promptly removed and the thrombus was aspirated through a percutaneous retrieval system. The thrombus cultural exam resulted positive for MRSA. After performing an extensive literature review, we could not find another case reporting the concomitance of these two rare complications. Conclusions: CRAT is a life-threatening complication in hemodialysis patients. While various treatment options exist, evidence-based guidelines are lacking, leading to individualized management strategies. Minimizing CVC use remains the best option for preventing such a complication. Full article

Among survivors of acute pulmonary embolism (PE), roughly half report persistent dyspnea, impaired functional status, and decreased quality of life. Post-pulmonary embolism syndrome (PPES) is a broad condition which has been increasingly recognized in recent years and may be due to post-pulmonary embolism functional impairment, chronic thromboembolic disease, or the most severe long-term complication of PE, chronic thromboembolic pulmonary hypertension. Despite guideline recommendations for appropriate follow-up for post-pulmonary embolism patients, PPES remains underrecognized and diagnostic testing underutilized. Patients with symptoms suggestive of PPES at follow-up should undergo a transthoracic echocardiogram to screen for the presence of pulmonary hypertension; additional testing, such as a ventilation/perfusion scan, right heart catheterization, and cardiopulmonary exercise testing may be indicated. The pathophysiology of post-pulmonary embolism syndrome is complex and heterogeneous. In chronic thromboembolic pulmonary hypertension, the pathophysiology reflects persistent pulmonary arterial thrombi and a progressive small vessel vasculopathy. In patients with chronic thromboembolic disease or chronic thromboembolic pulmonary hypertension, medical therapy, balloon pulmonary angioplasty, or pulmonary thromboendarterectomy should be considered, and in cases of chronic thromboembolic pulmonary hypertension, pulmonary thromboendarterectomy significantly improves mortality. In all causes of post-pulmonary embolism syndrome, rehabilitation is a safe treatment option that may improve quality of life. Full article

Background/Objectives: Left ventricular diastolic dysfunction (LVDD) and elevated left ventricular filling pressure (LVFP) are strong predictors of clinical outcomes across various populations. However, their diagnostic utility in embolic stroke of undetermined source (ESUS) remains unclear. We hypothesized that LVDD with elevated LVFP (based on echocardiography) was more likely to be prevalent in ESUS compared to non-cardioembolic stroke (NCE) and to be associated with atrial fibrillation (AF) on follow-up monitoring. Methods: This is a single-center retrospective study that included adult patients with a diagnosis of acute ischemic stroke between January 2016 and June 2017. LV function was assessed by inpatient transthoracic echocardiogram (TTE), and stroke etiology was adjudicated by the neurologist per the consensus criteria. Patients with cardioembolic stroke and those with indeterminate diastolic function on TTE were excluded. Baseline patient characteristics and clinical variables were compared among patients with and without LVDD and elevated LVFP. Multivariable regression models were used to assess the associations between diastolic dysfunction, ESUS, and AF detection in ESUS patients. Results: We identified 509 patients with ESUS and NCE stroke who had reported diastolic function. The mean age was 64.19 years, 45.19% were female, and 146 had LVDD with available LVFP data. LVDD was not associated with ESUS (adjusted OR: 1.43, 95% CI: 0.90–2.27, p = 0.130) or atrial fibrillation (AF) detection on cardiac monitoring (adjusted OR: 1.88, 95% CI: 0.75–4.72, p = 0.179). However, LVDD with elevated LVFP was borderline associated with ESUS (adjusted OR: 2.17, 95% CI: 0.99–4.77, p = 0.054) and significantly associated with AF detection (adjusted OR: 3.59, 95% CI: 1.07–12.06, p = 0.038). Conclusions: Our data suggest that LVDD with elevated LVFP is borderline associated with ESUS and significantly associated with AF detection on follow-up cardiac monitoring. Therefore, the presence of LVDD with an increased probability of elevated LVFP may help identify a subset of stroke patients more likely to have ESUS, potentially due to atrial cardiopathy with underlying occult AF. Further studies are needed to confirm our findings and to evaluate the safety and efficacy of anticoagulation in patients with ESUS and LVDD with elevated LVFP. Full article

Background: Cardiac arrest (CA) is a life-critical condition. Patients who survive after CA go into a defined post-cardiac arrest syndrome (PCAS). In this clinical context, the role of the echocardiogram in recent years has become increasingly important to assess the causes of arrest, the prognosis, and any direct and indirect complications dependent on cardiopulmonary resuscitation (CPR) maneu-vers. Methods: We have conduct a narrative revision of literature. Results: The aim of our review is to evaluate the increasingly important role of the transthoracic and transesophageal echocardiogram in the CA phase and especially post-arrest, analyzing the data already present in the literature. Conclusion: Transthoracic and transesophageal echocardiogram in the CA phase take on important diagnostic and prognostic role. Full article

Heartworm disease caused by Dirofilaria immitis is a serious and underdiagnosed cardiovascular condition in domestic ferrets. Hemodynamic changes caused by parasitization in ferrets cause a potentially fatal syndrome, but its clinical findings and treatment have not yet been standardized. The objective of this study was to describe the clinical case of a successful surgical extraction in a ferret infected by D. immitis. The patient was a 2-year-old, 1.5 kg asymptomatic male domestic ferret. The infection was diagnosed using a commercial test for the detection of D. immitis antigens. Subsequently, their clinical status was evaluated using serological and imaging diagnostic tests, and it was finally decided to perform surgical extraction of the adult worms. The ferret was anesthetized and placed in the left lateral decubitus position to perform a venotomy in the right jugular vein. Endoscopic extraction basket-shaped devices were used in the right atrial cavity under fluoroscopic guidance following the Seldinger endovascular surgery technique. With careful handling, two adult parasites were manually removed. A transthoracic echocardiogram performed after the procedure confirmed the absence of heartworms. The ferret recovered without complications and was discharged within 24 h. In the clinical review, 30 days after surgery, no notable alterations or symptoms were observed. This case report describes the first complete surgical removal of adult D. immitis parasites in a naturally infected ferret. Full article

Background: Clinical trials demonstrating improved cardiovascular outcomes with SGLT2 inhibitors have often had limited representation from Black and Hispanic populations. While the mechanisms of action are not well known, ethnicity- or gender-based receptor physiology may render SGLT2 inhibitors a better agent in certain populations over others. Methods: A medical records query yielded diabetic patients initiated on SGLT2 inhibitors between 2013 and 2020. Patients with coronary artery disease, cardiac arrhythmias, and heart failure were excluded. Transthoracic echocardiographic studies (TTE) before and after starting SGLT2 inhibitors were analyzed, and post-processing left ventricular global longitudinal strain (LV GLS) analysis was also performed on each echocardiographic study. Univariate outliers and patients with missing data were excluded. Results: Among 94 patients with TTE (mean age 60.7 years; 68% Hispanics, 22.3% Blacks; median follow up of 7 months), there were significant improvements in the mean LV GLS (−15.3 vs. −16.5; p = 0.01), LV mass (LVM) (198.4 ± 59.6 g vs. 187.05 ± 50.6 g; p = 0.04), and LV mass index (LVMI) (100.6 ± 26.6 g/m² vs. 94.3 ± 25.4 g/m²; p = 0.03) before and after initiating SGLT2 inhibitors but no significant change in the ratio (MV E/E’) of peak early diastolic mitral flow velocity (E) and spectral pulsed-wave Doppler-derived early diastolic velocity from the septal mitral annulus (E’) (12.5 ± 5.7 vs. 12.7 ± 4.8; p = 0.38). Changes in HbA1c (r² = 0.82; p = 0.026), LVM (r² = 0.20; p = 0.04), and LVMI (r² = 0.20; p = 0.04) were found to be independently associated with changes in values of LV GLS on follow-up echocardiograms, when compared to the pre-medication LV GLS number. Conclusion: Non-White diabetic patients receiving SGLT2 inhibitors against a backdrop of other cardioprotective medications demonstrate significant improvements in LV remodeling and LV GLS, driven in part by an improvement in glycemic control. Large, prospective studies are needed to explore the differences in the therapeutic actions of SGLT2 inhibitors among different populations. Full article

Background: Net atrioventricular compliance (C_n) can affect the accuracy of mitral valve area (MVA) assessment. We assessed how different methods of MVA assessment are affected by C_n, and if patients with abnormal C_n may be identified by clinical and/or echocardiographic parameters. Methods: We studied 244 patients with rheumatic MS. The concordance between mitral valve area (MVA) by 2D planimetry, pressure half-time (PHT), continuity equation (CE), Yeo’s index, and 3-dimensional mitral valve area assessed by transesophageal echocardiography (TEE 3DMVA) in patients with normal and abnormal C_n (C_n ≤ 4 mL/mmHg) were evaluated in the 110 patients with both transesophageal echocardiogram (TEE) and transthoracic echocardiogram (TTE). Variables that were associated with abnormal C_n were validated in the remaining 134 patients with only TTE. Results: Except for MVA by CE, concordance with TEE 3DMVA was poorer for all other methods of MVA assessment in patients with abnormal C_n. But, the difference in concordance was only statistically significant for MVA by PHT. Patients with MVA ≤ 1.5 cm² by 2D planimetry and PHT ≤ 130 ms were likely to have an abnormal C_n. (specificity 98.5%). This finding was validated in the remaining 134 patients (specificity 93%). Conclusions: MVA assessment by PHT is significantly affected by C_n. Abnormal C_n should be suspected when 2D planimetry MVA is ≤1.5 cm² together with an inappropriately short PHT that is ≤130 ms. In this scenario, MVA by PHT is inaccurate. Full article
