Key Points

To investigate how the presence of bilateral superior vena cava affects the transcatheter closure of sinus venosus defects.
Examined feasibility post-interrogation in cases with BilSVC
Evaluated stent diameters and stability during closure
Assessed residual leak and thrombosis rates
Feasibility of closure was lower in patients with BilSVC
Frequent need for balloon upsizing despite imaging predictions
Higher rates of thrombosis observed, impacting thromboprophylaxis

Implication

Post-interrogation findings show lower feasibility for transcatheter closure in bilateral superior vena cava, suggesting challenges in treatment.
