A 23-year-old basket-ball player was referred to the cardiology examination because of recurrent transient ischemic attack (TIA). The patient was asymptomatic, with no history of cardiovascular risk factors or previous heart disease. Clinical and electrocardiography parameters were unremarkable. Echocardiography showed a sack-like aneurysm of the membranous ventricular septum (AMS), approximately 15 x 9 mm in size, protruding into the right ventricle. Color Doppler revealed blood flow directly from the left ventricular cavity into the AMS through ventricular septal defect (VSD), approximately 2-3 mm in diameter. There were no signs of right ventricular outflow tract obstruction, infection or thrombosis. A spontaneous echo-contrast in the AMS was detected, suggested AMS as a most likely source of emboli responsible for recurrent TIA. Cardiac magnetic resonance (CMR) confirmed echocardiography findings. Complete resection of AMS and closure of VSD was done by a pericardial patch. Two years after surgical repair no other neurological event has occurred. AMS develops as a consequence of partial or complete spontaneous closure of a VSD, during various periods from the neonatal to 6 years of age. Large, hemodynamically significant, membranous VSD in infancy progresses to a functionally smaller defect with aneurysm formation later in childhood. In the most cases formed aneurysms completely close VSD. Due to that reason, AMS is generally asymptomatic and clinical examination fail to expose its presence. Therefore, in adult patients AMS is the most frequently detected accidentally, during echocardiography which is, generally, the only method needed for definite diagnosis. Computed tomography or cardiac magnetic resonance imaging can help delineate the extent of the AMS, its relationships to surrounding cardiac structures, and AMS thrombosis or inflammation. Clinical importance of AMS stems from potentially severe or fatal complications (e.g. tricuspid or aortic valve insufficiency, right ventricular outflow tract obstruction, rupture, thromboembolism, infectious endocarditis). Therefore, AMS should be operated on soon after diagnosis, even in asymptomatic patients. The only recommended surgical option is complete AMS resection and VSD closure with a patch.
