Case Report: Successful transcatheter repair of left ventricle-right atrium connection following ventricular septal defect surgery.

ABSTRACT:

Background

Left ventricle-right atrium (LV-RA) connection may develop secondary to ventricular septal defect (VSD) repair, particularly when the membranous septum or tricuspid valve is affected, leading to a leaflet defect. While surgery remains the standard treatment, reports of transcatheter valve closure are limited. This highlights the importance of exploring the safety and feasibility of transcatheter approaches for LV-RA connection, especially in high-risk patients.

Case presentation

This is the first reported case of a retrograde Konar-MF closure of an LV-RA connection on a 6-year-old male patient with a history of VSD surgery. Pre-procedural transesophageal echocardiography (TEE) showed a 4 mm defect in the septal leaflet of the tricuspid valve. A residual membranous
