Transcatheter self-expanding stent closure of sinus venosus atrial septal defects with indigenous method of determining appropriate stent length without advanced imaging techniques -A case series of single centre experience

Transcatheter closure of sinus venous Atrial Septal Defect (SVASD) was proving to be safe and effective with accumulating evidence. We report 3 cases of successful transcatheter closure of SVASD with indigenous reproducible technique without need for advanced imagining techniques with favourable outcomes. Three patients aged 27,42 and 44 years underwent successful closure of SVASD using self-expandable Endurant™ II stent graft (Medtronic) after undergoing pre-procedure successful balloon occlusion of Superior Vena Cava (SVC) without obstructing right upper pulmonary vein (RUPV) drainage. We used fluoroscopy, Trans-esophageal echocardiography (TEE) and marker pigtail for guiding measurements to choose appropriate stent size. One patient developed cardiac tamponade requiring surgical removal of stent with surgical closure of the defect.
