Balloon Uncrossable Left Main Coronary Artery Dissection: A Case Report and Literature Review.

ABSTRACT: Coronary artery dissection presents a high-risk scenario, particularly when complicated by severe calcification. We report a complex case of a balloon-uncrossable lesion encountered during percutaneous coronary intervention (PCI) of a calcified ostial-to-mid left anterior descending (LAD) artery lesion extending into the LMCA. A 54-year-old male with type 2 diabetes and exertional angina underwent coronary angiography revealing severe calcified LAD disease. Despite successful initial balloon pre-dilatation, a drug-eluting stent (DES) could not cross the lesion. Withdrawal attempts resulted in a large LMCA-to-LAD dissection flap, preventing further device passage. Urgent multidisciplinary consultation was initiated.
