TCT-680 Validation of Virtual to Coronary Distance in Native Transcatheter Aortic Valve Replacement

Iatrogenic coronary obstruction remains a devastating complication of transcatheter aortic valve replacement (TAVR). Recent studies demonstrated that a valve-to-coronary distance (VTC) <4 mm in valve-in-valve cases predicted coronary obstruction risk. The aim of our study was to apply this method
