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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>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\u2005mm defect in the septal leaflet of the tricuspid valve. A residual membranous septal aneurysm (MSA) extending from the subaortic region to the septal annulus of the tricuspid valve without residual shunt, and a small atrial septal defect (ASD) were also identified. The cardiac team performed closure using Konar-MF VSD Occluder No. 6\/8\u2005mm via a retrograde right femoral arterial approach, advancing the catheter through the left ventricle and across the defect. A well-positioned device with minimal residual central shunt and without peripheral leakage were confirmed from the post-procedural TEE. Clinical evaluation immediately after procedure and at 3-month follow-up demonstrated good results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
