Deep Learning-Enabled Assessment of Right Ventricular Function Improves Prognostication After Transcatheter Edge-to-Edge Repair for Mitral Regurgitation.

Background: Right ventricular (RV) function has a well-established prognostic role in patients with severe mitral regurgitation (MR) undergoing transcatheter edge-to-edge repair (TEER) and is typically assessed using echocardiography-measured tricuspid annular plane systolic excursion. Recently, a deep learning model has been proposed that accurately predicts RV ejection fraction (RVEF) from 2-dimensional echocardiographic videos, with similar diagnostic accuracy as 3-dimensional imaging. This study aimed to evaluate the prognostic value of the deep learning-predicted RVEF values in patients with severe MR undergoing TEER.

Overweight, obesity, and cardiovascular disease in heterozygous familial hypercholesterolaemia: the EAS FH Studies Collaboration registry.

Background And Aims: Overweight and obesity are modifiable risk factors for atherosclerotic cardiovascular disease (ASCVD) in the general population, but their prevalence in individuals with heterozygous familial hypercholesterolaemia (HeFH) and whether they confer additional risk of ASCVD independent of LDL cholesterol (LDL-C) remains unclear.

Methods: Cross-sectional analysis was conducted in 35 540 patients with HeFH across 50 countries, in the EAS FH Studies Collaboration registry. Prevalence of World Health Organization-defined body mass index categories was investigated in adults (n = 29 265) and children/adolescents (n = 6275); and their association with prevalent ASCVD.

Right ventricular coupling predicts cardiopulmonary fitness in cardiac transthyretin amyloidosis.

Background: Wild-type transthyretin cardiac amyloidosis (ATTRwt) is an infiltrative disease leading to restrictive cardiomyopathy. We aimed to characterise exercise capacity in ATTRwt and to identify predictors of cardiopulmonary fitness, focusing on echocardiographic and clinical parameters.

Methods: We studied 110 ATTRwt patients from a prospective single-centre registry (2020-2024) by cardiopulmonary exercise testing (CPET).

Intracoronary stenting and additional results achieved by shockWAVE coronary lithotripsy: design and rationale of ISAR-WAVE trial.

Background: Percutaneous coronary intervention of severely calcified lesions is limited by inadequate stent expansion and poor clinical outcomes. Over the past decade, several devices and techniques have been developed for calcium modification and lesion preparation. Intravascular lithotripsy (IVL) is a novel tool in this context.

Left ventricular systolic function after percutaneous coronary intervention: patterns of change and prognosis according to clinical presentation of coronary artery disease.

Background: Whether there are differences in the left ventricular ejection fraction change (ΔLVEF) after percutaneous coronary intervention (PCI) and its association with long-term prognosis according to coronary artery disease (CAD) presentations is unknown. We assessed ΔLVEF after PCI and its association with 5-year mortality in various CAD presentations.

Methods: This study included 8181 patients with paired (before and 6-8 months after PCI) angiographic LVEF measurements: 4582 patients with chronic coronary disease (CCD), 1972 patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and 1627 patients with ST-segment elevation myocardial infarction (STEMI).
