Case series demonstrates successful transcatheter closure of atrial septal defect using a suture-assisted technique, indicating safety and efficacy.

To report initial cases of closure of superior sinus venosus atrial septal defect using a suture-assisted technique.
Three patients selected for the technique; one excluded due to high pulmonary venous pressure.
Bilateral femoral venous and right internal jugular access were used.
Covered CP stent deployed via a two-balloon strategy.
Both procedures were technically successful with precise stent positioning.
Complete defect closure and unobstructed pulmonary venous drainage achieved.
Early follow-up confirmed stability and preserved pulmonary flow.

Dowaikh et al. (2025) studied this question.
