Abstract

A female with chronic atrial fibrillation presented with an acute myocardial infarction. The angiogram revealed total occlusion of the right coronary artery. A combined strategy using intracoronary thrombolysis, aspiration catheter, plain old balloon angioplasty, and "Fogarty-like" procedure was performed. However, we failed to achieve good coronary flow because the thrombus was large and hard with a calcified surface revealed by intravascular ultrasound examination. Ultimately, compression of the thrombus with the AngioSculpt™ scoring balloon catheter (AngioScore, Fremont, CA) led to resolution of normal coronary flow without the need for implantation of a coronary stent. Calcified thrombus is rarely observed in a coronary artery embolism, especially one formed in the left atrial appendage. In this case, the AngioSculpt scoring balloon catheter shows efficacy in treating this calcified thrombus.
