Under‐deployed TAVI with occluded left‐main and severe aortic regurgitation; bailout chimney‐in‐chimney stenting and aggressive postdilatation saves the day

Abstract

Abstract Narrow calcific aortic roots with low coronary heights present challenges for a successful trans‐catheter aortic valve replacement. We describe a case where pre‐emptive coronary protection and chimney stent‐in‐stent procedure was successfully performed during a cardiac arrest secondary to coronary occlusion and restricted TAVI valve deployment in such an anatomy.
