Crucial role of safety guidewire in transcatheter aortic valve implantation: Two cases with vascular complication.

Vascular complications increasing the rates of morbidity and mortality are among the most common complications observed during transcatheter aortic valve implantation (TAVI). Endovascular management is often life-saving. However, due to limitations of time in cases of iliac rupture and dissection, precautions taken prior to the procedure and the placement of safety guidewire in the contralateral femoral artery are crucial. Here, an 85-year-old woman and and 84-year-old man who had severe symptomatic aortic stenosis and underwent TAVI were presented. Although the valves were successfully implanted, the procedures were complicated by rupture and dissection of the right iliofemoral artery. With the use of safety guidewire, 2 self-expandable graft stents were inserted at the site of rupture and in the place of dissection in the iliofemoral artery, and the patients could be managed successfully.
