Abstract: Balloon rupture during transcatheter aortic valve replacement (TAVR) is a rare but serious complication. Here, we present two cases of balloon rupture in patients with severe aortic stenosis and type 0 bicuspid aortic valves. Three-dimensional models based on pre-procedure cardiac CT angiography were used to investigate these cases post hoc. The models revealed asymmetrical distribution of calcifications with sharply spiked features in the bicuspid aortic valves. The narrow calcified orifices resulted in uneve… Show more
