Iatrogenic aortic dissection of the descending aorta after percutaneous coronary intervention.

Abstract

Aortic dissection is a rare and potentially fatal complication of coronary angiography. We report a case of a woman in her late 80s who underwent a left femoral approach coronary angiogram for evaluation of a transcatheter aortic valve replacement (TAVR). Following the procedure, she had a cardiac arrest and was found to have a descending aortic dissection on transoesophageal echocardiogram. Autopsy showed an acute intimal tear of the descending aorta, most likely related to catheter manipulation. Patients undergoing evaluation for TAVR, who tend to be elderly with concomitant atherosclerosis, are at risk for complications following cardiac catheterisation including aortic dissection.
