Delayed presentation of left main coronary artery dissection due to catheter ablation in a patient with bicuspid aortic valve. Coincidence or manifestation of inherent vulnerability?

ABSTRACT: Left main coronary artery (LMCA) injury is an uncommon complication of catheter ablation. Due to the large myocardial area at risk, its presentation is usually acute with a dramatic course and life-threatening sequelae. Increased susceptibility to spontaneous coronary artery dissection has recently been implied in patients with bicuspid aortic valve (BAV). We present the first case of iatrogenic coronary dissection in a BAV patient, with an atypically delayed manifestation. The patient sustained ablation catheter-induced mechanical damage of LMCA due to its inadvertent penetration during the attempts to cross the aortic valve. After three days of recurring chest pain, he was readmitted with anterior myocardial infarction and imminent cardiogenic shock, and underwent emergent coronary stent
