Advancements in technology for the treatment of valvularcardiac diseases seek to provide solutions for high risk patients in the form of percutaneous valve insertion for patients with complicated valvular disease not amenable to more traditional options. Within the last decade, cardiac valves designed for percutaneous insertion have emerged rapidly as a treatment option for valvular disease. This procedure serves as an alternative to open heart surgery, which is more invasive and requires longer ICU stay. Thus, the percutaneous valve insertion procedure has been used on older, frailer patients who are poor candidates for open heart surgery. Designs for percutaneous valve insertion systems have been in development for decades, but have only recently been approved by the FDA for use. Important considerations include stent design, valve design, balloon catheter design, and deployment method.

One of the major issues encountered in patients undergoing evaluation for Transcatheter mitral valve replacement (TMVR) is the risk of Left ventricular outflow tract (LVOT) obstruction. LVOT obstruction is a catastrophic complication of TMVR, the result of displacement of the anterior mitral valve leaflet (AML) toward the interventricular septum. Several strategies to mitigate the risk of LVOT obstruction have been described and include percutaneous laceration of the anterior mitral leaflet (LAMPOON), alcohol septal ablation, trans-atrial leaflet modification (SITRAL) and Balloon Assisted Translocation of Mitral Anterior leaflet to prevent LVOT obstruction (BATMAN).

The year 2024 has witnessed substantial advancements in interventional cardiology, encompassing both coronary and structural interventions.In coronary field, trials have explored percutaneous innovations for coronary lesions, strategies for managing post‑infarction cardiogenic shock and non‑invasive approaches for guiding revascularization. The uploaded guidelines for chronic coronary syndromes emphasize individualized care, integrating modalities such as fractional flow reserve (FFR), intravascular ultrasound (IVUS), optical coherence tomography (OCT) and new teatments, including cochicine, GLP-1 receptor agonists and bempedoic acid.

Background: In developing countries evidences regarding pulmonary hypertension (PH) in rheumatic heart disease (RHD) patients are lacking, despite being responsible for significant morbidity and mortality. As a result, identifying the factors that influence PH is crucial to improve the quality of care.
Objective: To determine prevalence of pulmonary hypertension and its associated factors among rheumatic heart disease patients at the public hospitals of Bahir Dar city, Ethiopia.
Transcatheter closure of paravalvular leakage through multiple approaches after surgical mechanical valve replacements: A retrospective study.

Department of Cardiovascular Surgery, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi Province, China.
Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
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.
