Incidental discovery of a membranous ventricular septal aneurysm in two dissimilar patients.

Naidu A, Ricketts M, Goela A, Shoemaker G, Li S - Case Rep Cardiol (2012)

Bottom Line: It is uncommon for a VSA to exist in the absence of a known prior ventricular septal defect.We present two cases, each highlighting an incidental intact aneurysm involving the membranous interventricular septum.Clinical implications of the condition are reviewed.

ABSTRACT
A ventricular septal aneurysm (VSA) is a rare cardiac anomaly, and an accurate statistic of its prevalence has not been reported in the literature. True incidence is likely underestimated as most patients are thought to be asymptomatic. As a result, most VSAs are discovered incidentally on echocardiography, during angiography, or at autopsy. Potential complications include rupture, bacterial endocarditis, right ventricular outflow tract obstruction, and thromboembolic disease. It has been proposed that VSAs occur in association with ventricular septal defects (VSDs) and other congenital cardiac abnormalities. It is uncommon for a VSA to exist in the absence of a known prior ventricular septal defect. We present two cases, each highlighting an incidental intact aneurysm involving the membranous interventricular septum. We discuss the contrast in the two patients with regard to their age, accompanying cardiac anomalies and cardiovascular fitness. Clinical implications of the condition are reviewed.

Mentions: An 18-year-old female track and field athlete with bradycardia was referred to a cardiologist by her family physician to rule out a cardiac defect. She underwent a 2D echocardiogram, which revealed what was thought to represent a poorly visualized aneurysm. More specifically, the abnormality was initially felt to be an aneurysm of a sinus of Valsalva; though, the lack of certainty required further imaging. A prospectively gated contrast enhanced multidetector CT (MDCT) scan of the heart was performed. CT imaging (Figure 1) confirmed the presence of an aneurysm; however, it was located at the membranous interventricular septum immediately caudal to the level of the right coronary sinus. The aneurysm measured 1.2 × 0.9 cm, stretching the septum into the right ventricle. No accompanying VSD was evident.
