Resumo
Coronary obstruction is an uncommon and severe complication after a transcatheter aortic valve replacement (TAVR), that occurs during the procedure in the vast majority of patients. In the present case even in the absence of classic risk factors, an acute coronary syndrome occurred one day after TAVR. Selective angiography revealed a severe left main ostium obstruction by the bulky native leaflet calcification. This is the first case of delayed presentation of coronary obstruction with a transfemoral balloon-expandable valve using the Inovare bioprosthesis (Braile Biomedica, Brazil). In addition, after drug-eluting stent placement in the left main coronary, intravascular ultrasound revealed severe stent underexpansion, so that a second layer of a bare-metal stent and high-pressure balloon post-dilatation was necessary to improve the final result. The patient was discharged after 7 days, and at the 6-month follow-up remained asymptomatic. <Learning objective: This case illustrates an unusual cause of an acute coronary syndrome 24 h after a transcatheter aortic valve replacement. This is the first report of this severe complication with delayed presentation following the balloon-expandable Inovare bioprosthesis. Even in the absence of classic risk factors this complication may occur, and percutaneous coronary intervention is feasible in the vast majority of cases, often requiring various percutaneous techniques and intravascular image to improve outcomes.>
