Clinical Characteristics and Determinants of Ventricular Arrhythmias After Self‐Expandable Pulsta Valve Implantation in the Native Right Ventricular Outflow Tract

Woo Young Park, Gi Beom Kim, Sang Yun Lee, Mi Kyoung Song et autres

BACKGROUND: Ventricular arrhythmias (VA) after percutaneous pulmonary valve implantation (PPVI) have been mainly reported with balloon-expandable valves. Data on VA following self-expandable valves, particularly the Pulsta valve, remain limited. AIMS: To evaluate the incidence, clinical characteristics, and predictors of clinically significant VA …

Predictive Echocardiographic Parameters for Persistent Mitral Regurgitation Following Percutaneous Closure of Patent Ductus Arteriosus in Pediatric Population

Walaa Adem, Eun Young Bae, Gi Beom Kim, SangYun Lee et autres

Background Hemodynamically significant patent ductus arteriosus (hsPDA) leads to left‐sided chamber dilatation and mitral valve (MV) annular stretching, potentially resulting in mitral regurgitation (MR). While transcatheter PDA closure often improves MR, persistent MR may be associated with adverse outcomes. This study aimed …
