Traumatic ventricular septal defect: characterization with electrocardiogram-gated cardiac computed tomography angiography

Carlos A Rojas et al. J Thorac Imaging. 2012 Nov.

Abstract

Ventricular septal defects as a result of blunt trauma to the chest have not been frequently reported in the literature. In addition, the majority of these cases have been imaged with echocardiography alone. We report a case in which a ventricular septal defect caused by blunt chest trauma was characterized with electrocardiogram-gated computed tomography angiography. A review of the current literature and theories of injury mechanism are also provided.

Figures

Figure 1
Figure 1
Volume rendered CT images of a 28 year old man after blunt trauma to the chest demonstrate a contained rupture of the anterior wall of the LV (arrowheads), extending posteriorly to involve the basal anteroseptum creating an interventricular connection consistent with a traumatic VSD (black arrowhead) (A, B and C). Note the high attenuation contrast entering the “washed-out” RV (A and B), and the relationship of the left anterior descending (LAD) and diagonal (D) coronary arteries with the psuedoaneurysm and VSD (A). Ao= Aorta, LV= Left Ventricle, RV= Right Ventricle, RVOT= Right Ventricular Outflow Tract, PA= pulmonary artery.
