OBJECTIVE The aim of this article is to examine the frequency, timing of formation of aneurysm of the ventricular membranous septum (AVMS), and prognosis in patients with a perimembranous ventricular septal defect (VSD). METHODS One hundred forty-eight patients were diagnosed with a perimembranous VSD within 90 days after birth. They were classified into three groups: Group I, spontaneous closure; Group II, open; Group III, surgical closure. They were also divided into two further groups: 75 patients with congestive heart failure (CHF) and 73 patients without that. METHODS An AVMS was observed by two-dimensional echocardiography, and spontaneous closure of the VSD was confirmed by color Doppler. RESULTS An AVMS was formed in 69 (47%) of 148 patients: 50% in Group I, 66% in Group II, 15% in Group III. The timing of AVMS formation was at a median age of 6 months. In 14% of patients, AVMS was formed within 3 months of age. The frequency of AVMS at the time of the initial echocardiogram was low in patients with CHF (odds ratio, 3.23; 95% confidence interval, 1.19-8.79 p = 0.017). CONCLUSIONS We believe that AVMS formation is related to avoidance of surgical closure during early infancy in patients with a perimembranous VSD, because the frequency of AVMS during early infancy is low in patients with CHF.

D006322 Heart Aneurysm A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture. Cardiac Aneurysm,Aneurysm, Cardiac,Aneurysm, Heart,Aneurysms, Cardiac,Aneurysms, Heart,Cardiac Aneurysms,Heart Aneurysms
D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

D006345 Heart Septal Defects, Ventricular Developmental abnormalities in any portion of the VENTRICULAR SEPTUM resulting in abnormal communications between the two lower chambers of the heart. Classification of ventricular septal defects is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect.
