Key result
Transseptal occlusion with Amplatzer Vascular Plug-II successfully closes a persistent LSVC draining to the LA.
Why the study?
A persistent LSVC draining directly to the left atrium causes a right-to-left shunt and systemic desaturation, and transcatheter occlusion offers an alternative to historical surgical management.

Demonstrates the feasibility of a novel transseptal approach for transcatheter occlusion of a persistent left superior vena cava draining into the left atrium using an Amplatzer Vascular Plug-II.
A persistent left superior vena cava (LSVC) is a common venous anomaly, occurring in up to 10% of patients with congenital heart defects. Usually, a LSVC drains into the coronary sinus, then to the right atrium. The LSVC can drain directly to the left atrium, resulting in a right-to-left shunt and systemic desaturation. Historically, surgery has been used to address this lesion. Transcatheter occlusion of the LSVC is an alternative to surgery. We report the novel use of the transseptal approach to access the LSVC, and device occlusion using the Amplatzer Vascular Plug-II.

Zampi et al. (2013) conducted a case report in Persistent left superior vena cava draining to the left atrium. Transcatheter occlusion using the transseptal approach and Amplatzer Vascular Plug-II was evaluated. Transcatheter occlusion of a persistent left superior vena cava draining to the left atrium was successfully performed using a transseptal approach and the Amplatzer Vascular Plug-II.
