Letter to Editor: Acute left main coronary artery occlusion following TAVI and emergency solution

Transcatheter aortic valve implantation (TAVI) is an alternative therapy in patients with severe aortic stenosis(AS) and high surgical risk (1). TAVI have high procedural mortality rate such as valve embolization, stroke, perforation and the obstruction of coronary ostia (2). We present a TAVI case complicated acute left main coronary artery (LMCA) obstruction after TAVI. An 85 years old female was admitted with hypertension, atrial fibrillation, COPD and known severe AS that was refused for surgery in the past. Echocardiography demonstrated a severe calcified AS with valve area 0.3 cm2, mean gradient 45 mmHg and left ventricular ejection fraction 65%. Coronary angiography was almost normal. The patient was underwent transfemoral TAVI procedure with calculated EuroSCORE 18%.
