Delayed coronary artery occlusion after transcatheter aortic valve replacement and chimney stenting: a case report.
Ontology highlight
ABSTRACT: Background
Delayed coronary artery occlusion (CAO) is a rare but fatal complication after transcatheter aortic valve replacement, chimney stenting is the standard technique for established CAO or impending CAO.Case presentation
We describe a female patient who developed non-ST elevation myocardial infarction after receiving transcatheter aortic valve replacement and chimney stenting 4 months prior. An angiogram revealed delayed coronary artery occlusion with a deformed stent, which was never reported. This patient was subsequently treated with a new chimney stent.Conclusions
For self-expanding valves, the coronary ostium is protected by chimney stenting, delayed coronary artery occlusion can occur and cause catastrophic complications.
