Modified approach for transcatheter correction of superior sinus venosus atrial septal defect: a case series.

Transcatheter correction of SVASD with PAPVD was performed without any complications. The follow-up period was 7.8, 13.6, and 29.8 months, respectively. During follow-up, no mortality, stent embolization, or obstruction of pulmonary venous drainage occurred. The TOE-guided modified transcatheter approach for correction of SVASD with PAPVD is safe and feasible with excellent post-procedural results and represents an alternative to surgical treatment in a pre-selected patient cohort.
