A Rare but Deadly Complication of Transcatheter Aortic Valve Replacement.

We present a rare case of delayed coronary artery obstruction following a transcatheter aortic valve replacement (TAVR). Interestingly, the patient did not meet the criteria for traditionally recognized risk factors for delayed coronary obstruction. This case piques interest as to whether the severity of calcification on aortic valve leaflets plays any role in coronary obstruction post transcatheter aortic valve replacement. There is no consensus as to the optimal approach to investigation and revascularization in patients with delayed coronary obstruction. We report a case with successful emergent revascularization of the left main coronary artery following transcatheter aortic valve replacement.
