Aortic valve aneurysm involved in interventricular septum

ed to the outpatient department of our hospital with complaints of intermittent fever and exertional dyspnea since 2 months. On physical examination, a grade 3/6 diastolic murmur was heard. Blood cultures had persistently grown gram-positive enterococci. Two-dimensional transthoracic echocardiogram that was performed revealed a large aneurysm in the right coronary leaflet involving the basal septum (Fig. 1, Video 1) with severe aortic insufficiency and left ventricular chamber dilatation. Color Doppler echocardiography identified perforation of the aneurysm as a cause of aortic insufficiency and demonstrated diastolic aortic regurgitation from the perforation flowing into the left ventricular outflow tract (Fig. 2). Three-dimensional transesophageal echocardiography more clearly revealed the aneurysm with multiple perforations (Fig. 3, Video 2). After a regular antibiotic treatment, the patient’s blood cultures were negative, and an operation was finally performed. The same findings were observed as described above. Aortic valve aneurysms are rare. There are only a few studies reporting aortic valve aneurysms because of endocarditis. We used three-dimensional transesophageal echocardiography to examine an extremely rare large aneurysm that was involved in the interventricular septum with multiple perforations.
