There is little information in the literature about the obstruction of the coronary ostia after percutaneous aortic valve implantation. 81 TAVI sites and programs and 6688 patients in total provided information on this complication. Of all, 28 patients (0.66%) developed this complication, being more frequent for balloon-expandable prosthesis and when procedures were performed “valve in valve“. In these patients, intraoperative death was 15.9% and in-hospital death was 40.9%. 81.8% could be treated by angioplasty.
Conclusion: damage of the coronary ostia during TAVI is rare and is associated with high morbi-mortality.
