Delayed coronary artery occlusion after transcatheter aortic valve replacement and chimney stenting: a case report

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 myocardia...

description 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. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s12872-021-02249-2.
