Echocardiography is routinely performed for the evaluation of valvular regurgitation. Different applications of Doppler echocardiography have been successfully applied to detect and quantify valvular regurgitation. Recent advances in color Doppler made possible the study of the dynamic behavior of the regurgitant orifice and, along with continuous wave Doppler, can provide data on the regurgitant volume and fraction. Doppler echocardiography can also be used to follow serial changes in these hemodynamically important parameters after medical or surgical therapy.

Prevalence and Prognostic Significance of Malnutrition Risk in Patients With Valvular Heart Disease.
JACC Adv
January 2025
Department of Cardiology, The Third-Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China.
Background: Previous studies on the prevalence and prognosis of nutritional status in valvular heart disease (VHD) were primarily limited to aortic stenosis. The nutritional status of other types of VHDs remained an underexplored area.
Objectives: This study aimed to evaluate the prevalence of malnutrition risk in different types of VHD and investigate the association between malnutrition risk and adverse clinical events.
Prevalence and predictors of left atrial thrombus in patients with rheumatic atrial fibrillation undergoing cardiac surgery: a cross-sectional study.

Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital Fudan University, Shanghai, China.
Background: Unlike non-rheumatic atrial fibrillation (AF), where left atrial thrombus (LAT) is predominantly confined to the left atrial appendage (LAA), a significant proportion of LAT in rheumatic AF occurs within the left atrial cavity (LAC). However, LAC thrombosis in rheumatic AF has not been extensively studied. This study aimed to evaluate the prevalence of LAT and its subtypes and identify potential predictors of LAT.

Aortic regurgitation (AR) is more prevalent in male, although cellular and molecular mechanisms underlying the sex differences in prevalence and pathophysiology are unknown. This study evaluates the impact of sex on aortic valve (AV) inflammation and remodeling as well as the cellular differences in valvular interstitial cells (VICs) and valvular endothelial cells (VECs) in patients with AR. A total of 144 patients (27.

Article Synopsis
- The study focuses on the outcomes of aortic valve replacement (AVR) in young Moroccan patients with severe aortic regurgitation and impaired left ventricle function.
- A total of 42 out of 110 patients with significant aortic regurgitation and an ejection fraction of ≤35% underwent AVR, showing a low immediate postoperative mortality rate of 4.7%.
- Long-term follow-up indicated a high survival rate of 86.8% after 15 years, along with significant clinical improvements and increased left ventricle ejection fraction post-surgery.
Atrial Functional Mitral Regurgitation: Definition, Mechanisms, and Treatment Perspectives.
Curr Cardiol Rep
January 2025
Hasselt University, Faculty of Medicine and Life Sciences / Limburg Clinical Research Centre, Agoralaan, Diepenbeek, Belgium.
Purpose Of Review: This review aims to explore the complex interplay between atrial functional mitral regurgitation (AFMR), atrial fibrillation (AF), and heart failure with preserved ejection fraction (HFpEF). The goal is to define these conditions, examine their underlying mechanisms, and discuss treatment perspectives, particularly addressing diagnostic challenges.
Recent Findings: Recent research highlights the rising prevalence of AFMR, now accounting for nearly one-third of significant mitral regurgitation cases.
