Core Tip
Core tip: The aim of this study was to explore the feasibility and safety of transcatheter closure of perimembranous ventricular septal defects (PmVSD) with abnormally attached tricuspid chordae tendineae using an improved PDA occluder. A total of 20 patients diagnosed with PmVSD with abnormally attached tricuspid chordae tendineae who underwent interventional treatment using the improved patent ductus arteriosus (PDA) occluder were observed. All 20 patients achieved procedure success, and no residual shunt or severe tricuspid regurgitation was observed. Our study suggested that using of the improved PDA occluder for the transcatheter closure of PmVSD with abnormally attached tricuspid chordae tendineae is a safe and promising treatment option.
