Mitral regurgitation (MR) is one of the most common valvular heart diseases worldwide. Echocardiography remains the first line and most effective imaging modality for the diagnosis of mitral valve (MV) pathology and quantitative assessment of MR. The advent of three-dimensional echocardiography has significantly enhanced the evaluation of MV anatomy and function.

Background: Functional mitral regurgitation (MR) is a common form of mitral valve dysfunction that often persists even after surgical intervention, requiring reoperation in some cases. To advance our understanding of the pathogenesis of functional MR, it is crucial to characterize the cellular composition of the mitral valve leaflet and identify molecular changes in each cell subtype within the mitral valves of MR patients. Therefore, we aimed to comprehensively examine the cellular and molecular components of mitral valves in patients with MR.

Purpose: Bacteremia is a well-known complication to surgery and may result in infective endocarditis (IE). Transurethral resection of the prostate (TUR-P) may give rise to bacteremia, but the associated risk of IE is not well described. We aimed to examine risk of infective endocarditis following TUR-P.

Background: Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear in moderate MR. We therefore explored the prognostic impact of both moderate and severe MR within the large National Echocardiography Database Australia cohort.
Methods: Echocardiography reports from 608 570 individuals were examined using natural language processing to identify MR severity and leaflet pathology.

We conducted a high-risk redo mitral valve replacement through a right mini-thoracotomy without rib spreading (redo-MICS MVR) under systemic hyperkalemia combined with circulatory arrest to circumvent complications associated with cardioplegia delivery. The patient, a 75-year-old man, had a predicted mortality rate of 20%. Initial antegrade cardioplegia successfully induced cardiac arrest, which was administered every 30 min.

Background: The precise etiology of hypoplasia of the posterior mitral valve leaflet (PMVL) remains incompletely elucidated; however, it has been hypothesized to stem from genetic mutations occurring during fetal development. Herein, we present the anatomical characteristics of the mitral valve and associated cardiac pathologies in patients with hypoplastic PMVL.
Methods: This single-center retrospective study involved patients who presented between 2015 and 2021 at a tertiary healthcare facility.

Background: Catheter ablation is a common treatment for atrial fibrillation (AF), but recurrence rates remain variable. Predicting the success of catheter ablation is crucial for patient selection and management. This research seeks to create a machine learning model to forecast the early recurrence of atrial fibrillation following catheter ablation.

This study aims to compare 1-year outcomes after transcatheter aortic valve replacement (TAVR) between patients with moderate-severe MR and severe MR preoperatively using the Japan Transcatheter Valve Therapy (J-TVT) registry. Patients undergoing TAVR for aortic stenosis between August 2013 and December 2019 with preoperative mitral regurgitation of moderate-severe (group MR3) or severe (group MR4) were included. Patients with a history of valve surgery and dialysis patients were excluded.

Background: The optimal treatment for ischemic mitral regurgitation (IMR) in patients of non-ST elevation myocardial infarction (NSTEMI) is a debated topic.
Objective: To evaluate the long term outcome on patients with NSTEMI and IMR, particularly emphasizing the comparison of treatments in those with moderate to severe MR.
Methods: We enrolled patients with NSTEMI and classified non/trivial to mild regurgitation as insignificant IMR and moderate to severe regurgitation as significant IMR.

Background: Mitral regurgitation (MR) is the most common form of valvular heart disease (VHD), and the accurate assessment of MR severity is critical for clinical management. However, the quantitative assessment of MR is intricate and time-consuming, posing challenges for physicians in ensuring the precision of the results. Thus, our objective was to create an automated and reproducible artificial intelligence (AI) system.

Background: The management of ventricular septal defect (VSD) alongside mitral regurgitation (MR) in pediatric patients remains a contentious issue due to the intricacies of cardiac surgery and the need to minimize ischemic time. Despite observations of MR regression following VSD closure, definitive guidelines for this patient subset are lacking, particularly concerning the management of the subgroup of patients with moderate MR. The objective of the study is to explore the factors influencing the choice between surgical intervention and conservative management for the mitral valve (MV) in VSD patients with moderate MR.

Background: Coronary air embolism (CAE) is a complication that can lead to catastrophic outcomes, including myocardial infarction, stroke, and death. It is reported to occur during cardiac catheterization, within a few hours after cardiac surgery, or as a result of chest trauma. This is a case report of delayed coronary air embolism following cardiac surgery.

Background: The prevalence and impact of right ventricular dysfunction (RVD) in degenerative mitral regurgitation (DMR) is unknown. We aimed to determine whether RVD assessed by echocardiography in routine clinical practice is independently associated with mortality in patients with DMR.
Methods And Results: We used data from the MIDA-Q (Mitral Regurgitation International DAtabase-Quantitative) registry, which included patients with isolated DMR due to mitral valve prolapse from January 2003 to January 2020 from 5 tertiary centers across North America, Europe, and the Middle East.

To evaluate the clinical outcomes of combined complete preservation of chordal structure mitral valve replacement (C-MVR) with total anatomical arterial myocardial revascularization (TACR) in coronary patients with moderate-to-severe or severe ischemic mitral regurgitation (IMR). This is a retrospective multi-center case series study. Data were retrospectively collected from 127 patients with coronary artery disease with moderate to severe or severe IMR who received TACR with C-MVR from July 2015 to April 2024 in 13 hospitals in China.

Introduction: Acute valvular emergencies, a time-sensitive diagnosis, are nearly impossible to diagnose without ultrasound, and missing the diagnosis can significantly impact patient outcomes. Many emergency physicians lack access to echo technicians and may be uncomfortable performing the ultrasound themselves. Approaching the paucity of review articles, none of which are focused for the emergency physician, can be quite daunting, even for those with extensive ultrasound training.

Background: A small mitral valve area (MVA) is one of the challenging anatomies for transcatheter edge-to-edge repair (TEER) for mitral regurgitation, but the relationship between baseline MVA and clinical outcomes remains unknown. This study aimed to evaluate the association of baseline MVA with procedural and clinical outcomes in patients undergoing TEER with MitraClip from the OCEAN-Mitral registry (Optimized Catheter Valvular Intervention-Mitral).
Methods: A total of 1768 patients undergoing TEER were divided into 3 groups according to baseline MVA: group 1: <4.
