Traumatic right ventricular rupture: Case report and brief review of the literature

Rupture of the right ventricular (RV) myocardium is associated with serious morbidity and mortality. Under very rare conditions, a tear in the ventricular wall can lead to the formation of a pseudoaneurysm: an external outpouching of the ventricle that is stabilized by the pericardium, thrombus formation, and/or adhesions. Here, we present a 75-year-old man with RV free wall rupture with pseudoaneurysm following a motor vehicle collision. With concerns for blunt cardiac trauma, initial CTA chest revealed focal outpouching and extension of contrast outside of the confines of the RV chamber, compatible with pseudoaneurysm formation. In this case, conservative management of the pseudoaneurysm was preferred over surgical management, due to the thin RV free wall and present comorbid conditions. We highlight how CTA chest offers a reliable tool for tracking the stability of pseudoaneurysms in the RV and can guide clinical management through directing treatment strategies and appropriate follow-up intervals.
