Cerebral embolism and thrombus in a membranous interventricular septal aneurysm

Tricuspid Pouch can Cause Systemic Embolization in Adulthood

“…A report of tricuspid pouch is rare because the final diagnosis of tricuspid pouch is made during cardiac surgery. Rhythm disturbances have been reported in associated with AMS, 13 but none of the reported cases of AMS with thrombo-embolism had cardiac arrhythmias, 12 nor was there evidence of atrial fibrillation or ventricular premature contraction on Holter ECG in the present case.…”

“…Thrombo-embolic complications with tricuspid pouch are very rare, but may be underestimated, as in the past with aneurysm of the interatrial septum, which was considered to be a potential cause of thromboembolism. Previous investigators have reported complications of AMS, such as cerebral infarction, [9][10][11][12] and all of these previous cases underwent surgery because there was possibility of thrombus in the future. A report of tricuspid pouch is rare because the final diagnosis of tricuspid pouch is made during cardiac surgery.…”

Clinical Significance of Incidentally Detected Aneurysms of the Membranous Ventricular Septum in Adults by Multidetector Computed Tomography

“…However, unlike in our study, in those previous studies, the thrombi were large and compactly filled almost the whole space of the AMVS. 2,4 Our study has several limitations. First, we did not estimate the real incidence of AMVS and the exact frequency of clinical events in the general population because this retrospective study was performed at a tertiary medical center with highly selective patients.…”

Aneurysm of the membranous interventricular septum demonstrated by multislice computed tomography

“…Most aneurysm of the membranous interventricular septum are asymptomatic, but it may cause cerebral embolization [3] and right ventricular outflow tract obstruction [4]. Although echocardiography is an effective tool for diagnosing aneurysm of the membranous ventricular septum [2], the detailed morphological assessment of the aneurysm is sometimes obscure.…”
