An 83-Year-Old Woman Undergoing Left Main Coronary Angioplasty: A Case Report

Document Type : Case Report


Cardiovascular Research Center, Shahid Beheshti University of Medical Sciences, Tehran, IR Iran.


Several studies have shown that during ischemia, repolarization indices such as QTC are prolonged. We describe a typical case with left main disease and prolonged QTC recovering to the normal range after angioplasty. (Iranian Heart Journal 2022; 23(4): 97-101)
