Expanding pseudoaneurysm compressing the coronary arteries and causing cardiogenic shock

J Cardiovasc Comput Tomogr. 2015 May-Jun;9(3):230-1. doi: 10.1016/j.jcct.2014.12.003. Epub 2014 Dec 26.

Abstract

A 37-year-old man who recently underwent aortic valve replacement after endocarditis presented with cardiogenic shock. A large expansile pseudoaneurysm was subsequently discovered using multiple imaging modalities. Although transesophageal echocardiography is important in diagnosing valve endocarditis, coronary CT angiography of prosthetic valves is feasible and image quality is good. In this case, coronary CT angiography allowed for better understanding of transesophageal echocardiography images and earlier diagnosis of coronary involvement as cause for left ventricular dysfunction.
