Sex-Specific Insights into Etiology, Diagnosis, Treatment, and Prognosis in Significant Tricuspid Regurgitation: A Narrative Review.

In recent decades, a burgeoning interest in tricuspid regurgitation (TR) has been prompted by a heightened awareness of its prevalence and the advent of dedicated percutaneous treatment approaches. Despite considerable understanding of its intricate anatomy and response to varying pressure and loading conditions, the impact of biological sex remains a subject of investigation. While TR typically afflicts more women, significant differences in TR etiology and post-treatment outcomes have not been conclusively established.

Metabolomic insights in advanced cardiomyopathy of chronic chagasic and idiopathic patients that underwent heart transplant.

Heart failure (HF) studies typically focus on ischemic and idiopathic heart diseases. Chronic chagasic cardiomyopathy (CCC) is a progressive degenerative inflammatory condition highly prevalent in Latin America that leads to a disturbance of cardiac conduction system. Despite its clinical and epidemiological importance, CCC molecular pathogenesis is poorly understood.

Biventricular Takotsubo syndrome complicated with cardiogenic shock and ventricular septal rupture: a case report.

Background: Takotsubo syndrome (TTS) mimics acute coronary syndromes but can lead to serious cardiac complications, emphasizing the need for improved understanding and management.

Case Summary: We describe a TTS case presented with cardiogenic shock due to ventricular septal rupture (VSR). Successful treatment involved mechanical circulatory support followed by VSR surgical closure.

Attainment of LDL-Cholesterol Goals in Patients with Previous Myocardial Infarction: A Real-World Cross-Sectional Analysis.

Background: The European Society of Cardiology guidelines recommend an LDL-cholesterol (LDL-C) < 55 mg/dL for patients with established cardiovascular disease. While the Friedewald equation to estimate LDL-C is still widely used, the newer Martin-Hopkins equation has shown greater accuracy.

Objectives: We aimed to assess: A) the proportion of patients reaching LDL-C goal and the therapies used in a tertiary center; B) the impact of using the Martin-Hopkins method instead of Friedewald's on the proportion of controlled patients.

20-year follow-up of rheumatic mitral stenosis patients after percutaneous mitral commissurotomy: invasive transmitral gradient differential as a predictor of events.

Percutaneous mitral valve commissurotomy (PMC) is a viable alternative to mitral valve (MV) surgery in the treatment of patients with rheumatic mitral stenosis (RMS). In this single-center retrospective study of consecutive patients with RMS submitted to PMC from 1991 to 2008, we analyzed clinical, echocardiographic, and hemodynamic data and events during follow-up (FUP) until December 2021. Major adverse cardiovascular events (MACE) were a combined endpoint of all-cause death, cardiovascular hospitalization, and MV re-intervention.

Parameters of the mitral apparatus in patients with ischemic and nonischemic dilated cardiomyopathy.

The mitral valve apparatus is a complex structure consisting of several coordinating components: the , two leaflets, the and the papillary muscles. Due to the intricate interplay between the mitral valve and the left ventricle, a disease of the latter may influence the normal function of the former. As a consequence, valve insufficiency may arise despite the absence of organic valve disease.

Is dyslipidemia a risk factor for trastuzumab-induced cardiotoxicity in breast cancer patients? A systematic review and meta-analysis.

Introduction: Breast cancer patients undergoing trastuzumab therapy have greater risk of cardiovascular disease. Risk factors for this effect have been proposed. However, the role of dyslipidemia is not completely understood.

Cardiovascular toxicity in breast cancer patients - contributors and role of cardioprotective drugs.

Breast cancer (BC) patients treated with anthracyclines and/or anti-HER2-targeted therapies (AHT) are highly associated with cardiovascular toxicity (CVT). Our objective was to evaluate the risk of CVT secondary to cancer treatment and the role of cardioprotective-drugs (CPD) in BC patients. We collected a retrospective cohort of females with BC treated with chemotherapy and/or AHT from 2017 to 2019.

Pretreatment with a P2Y12 receptor inhibitor and delay to coronary artery bypass surgery in patients with non-ST segment elevation acute coronary syndrome.

Background: 2020 ESC guidelines for non-ST elevation acute coronary syndromes (NSTE-ACS) recommend against the pretreatment with P2Y12 receptor inhibitors (P2Y12i) in patients undergoing early invasive management (<24 h). The rationale is, in part, to prevent bleeding complications and the delay of coronary artery bypass graft surgery (CABG) in patients with suitable coronary anatomy. This study aimed to analyze the theoretical impact of pretreatment with a P2Y12i on delay to CABG surgery in a real-world population with NSTE-ACS.

Impact of common rhythm disturbances on echocardiographic measurements and interpretation.

Transthoracic echocardiography (TTE) remains the workhorse of noninvasive cardiac imaging, allowing to easily obtain precise information on cardiac structure and function. Over time, Doppler interrogation of blood flow velocities, direction, and timing in several locations within the heart became the primary method for haemodynamic assessment, replacing cardiac catheterization in most clinical settings and providing valuable diagnostic and prognostic information on a wide spectrum of cardiac pathological processes. Abnormalities in heart rate, rhythm, and intracardiac electrical conduction are commonly encountered during the performance of echocardiographic studies.

Acute Cellular Rejection in Heart Transplant Patients: Insights of Global Longitudinal Strain, Myocardial Work, and an Exclusive Group of Chagas Disease.

Background: Echocardiographic markers associated with asymptomatic acute cellular rejection (ACR) in patients with orthotopic heart transplant (HT) are still under investigation. The aim of our study was to determine clinical and myocardial strain imaging (MSI) variables evaluated by echocardiography associated with ACR in the first year of HT. A separate analysis was performed to compare variables during the first 6 months of HT, when ACR has a prevalence in 60% of patients.

Innovative Approaches to Assess Intermediate Cardiovascular Risk Subjects: A Review From Clinical to Metabolomics Strategies.

Current risk stratification strategies for coronary artery disease (CAD) have low predictive value in asymptomatic subjects classified as intermediate cardiovascular risk. This is relevant because not all coronary events occur in individuals with traditional multiple risk factors. Most importantly, the first manifestation of the disease may be either sudden cardiac death or acute coronary syndrome, after rupture and thrombosis of an unstable non-obstructive atherosclerotic plaque, which was previously silent.

Pectoralis major muscle quantification by cardiac MRI is a strong predictor of major events in HF.

Clinical overt cardiac cachexia is a late ominous sign in patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). The main goal of this study was to assess the feasibility and prognostic significance of muscle mass quantification by cardiac magnetic resonance (CMR) in HF with reduced LVEF. HF patients with LVEF < 40% (HFrEF) referred for CMR were retrospectively identified in a single center.
