Long-diameter sizing may suffice more often in non-circular ASDs; leaves open need for shape-adjusted protocols in transcatheter closure.
Does the balloon occlusive diameter differ relative to the long diameter in non-circular versus circular atrial septal defects during transcatheter closure?
In transcatheter ASD closure, the balloon occlusive diameter is closer to the long diameter in non-circular defects compared to circular defects, especially in those with a large long diameter.
