What is Coronary Protection to Prevent Coronary Obstruction During TAVR: A Multicenter International Registry about?

## Objectives: The aim of this study was to investigate the safety and efficacy of coronary protection by preventive coronary wiring and stenting across the coronary ostia in patients at high risk for coronary obstruction after transcatheter aortic valve replacement (tavr). ## Background: Coronary obstruction following tavr is a life-threatening complication with high procedural and short-term mortality. ## Methods: Data were collected retrospectively from a multicenter international registry between april 2011 and february 2019. ## Results: Among 236 patients undergoing coronary protection with preventive coronary wiring, 143 had eventually stents implanted across the coronary ostia after valve deployment. at 3-year follow-up, rates of cardiac death were 7.8% in patients receiving stents and 15.7% in those not receiving stents (adjusted hazard ratio: 0.42; 95% confidence interval: 0.14 to 1.28; p = 0.13). there were 2 definite stent thromboses (0.9%) in patients receiving stents, both occurring after tavr in "valve-in-valve" procedures. in patients not receiving stents, there were 4 delayed coronary occlusions (dcos) (4.3%), occurring from 5 min to 6 h after wire removal. three ca
