Article Abstract
Background: Small cavity left ventricle (SCLV) may affect the clinical outcomes of patients undergoing mitral valve replacement (MVR). This study aims to investigate the incidence of SCLV in patients with rheumatic mitral valve stenosis undergoing MVR and analyze its effect on short-term patient outcomes.
Methods: We retrospectively examined all consecutive patients with isolated or concomitant MVR for rheumatic mitral valve stenosis in our center from 2013 to 2018. SCLV was defined as end-diastolic volume index ≤ 50 ml/m2. After inclusion and exclusion, a total of 1,437 patients were analyzed. The baseline information was collected and compared between SCLV and non-SCLV patients. Multivariate logistic regression analysis was conducted to determine the effect of SCLV on early mortality.
Results: A total of 1,437 patients were included in the study. SCLV was detected in 13.57% of the patients. Compared with the non-SCLV group, patients with SCLV were smaller-sized and primarily female. There were no significant differences between SCLV and non-SCLV patients regarding major postoperative complications, nor were there incidence of prosthesis-patient mismatch. Logistic regression analysis showed that SCLV was not a risk factor for short-term mortality (P = 0.998).
Conclusions: Our results demonstrated that SCLV was not associated with poorer early outcomes after MVR surgery in patients with rheumatic mitral valve stenosis.

Background: Long-term outcomes of transcatheter mitral valve edge-to-edge repair (TEER) are compared with medical therapy remain under investigation. This study evaluated the 3-year effects of MitraClip on mitral regurgitation (MR) severity, ventricular remodeling, and clinical outcomes in high surgical-risk patients.
Methods: A single-center retrospective cohort included 31 MitraClip patients (2016-2023) and 30 contemporaneous controls on maximally tolerated guideline-directed medical therapy.

Background: Pulmonary hypertension (PH) often coexists in patients undergoing transcatheter edge-to-edge mitral valve repair procedure (M-TEER). Its pre-procedural severity is considered a negative prognostic marker. Whether the post-procedural PH resulting from M-TEER can also serve as a long-term prognostic marker is unknown.

Background: Atrial functional mitral regurgitation (AFMR) is prevalent among patients with heart failure with preserved ejection fraction (HFpEF) and associated with adverse outcome, yet this bidirectional association remains underexplored.
Objectives: The purpose of this study was to elucidate the pathophysiological and prognostic significance of AFMR in HFpEF, both at rest and during exercise.
Methods: In this multicenter cohort study, consecutive patients with HFpEF underwent cardiopulmonary exercise testing with echocardiography, with a particular focus on mitral regurgitation (MR) severity assessment in rest and during exercise.

Objective: To compare the clinical outcomes of double-valve replacement (DVR) using bovine pericardial and porcine bioprostheses, using a nationwide administrative claims database.
Methods: Adult patients (age ≥40 years) who underwent bioprosthetic DVR between 2003 and 2018 were identified from the Korean National Health Insurance Service database. The outcomes of interest were all-cause mortality, cardiac mortality, and valve-related events, including the incidences of reoperation, endocarditis, systemic thromboembolism, and major bleeding.

Objectives: Left ventricular vortex dynamics play a crucial role in cardiac function but are significantly altered by mitral valve diseases or surgical interventions. Such hemodynamic changes may lead to maladaptive intracardiac vortices, potentially triggering pathways associated with progressive left ventricular remodeling and thrombosis. This study assessed left ventricular hemodynamics under both physiological and pathological conditions using a biohybrid in vitro platform, aiming to analyze the impact of these conditions on cardiac function.
