A unique cause of coronary obstruction after transcatheter aortic valve replacement.

Delayed coronary obstruction is a rare but often fatal complication of transcatheter aortic valve replacement that can present within 24 hr after the transcatheter aortic valve replacement procedure. We present a case of a 77-year-old woman whose distal left main coronary artery bifurcation became obstructed by an embolized piece of native valve leaflet material 16 hours after the uncomplicated transfemoral implantation of an Edwards Sapien Ultra 23 mm aortic valve, which was successfully treated with the simultaneous kissing stent technique.
