Anomalies of the membranous portion of the interventricular septum include perimembranous ventricular septal defect and/or membranous septal aneurysm (MSA). In congenitally corrected transposition of the great arteries (L-TGA in sinus solitus), the combination of ventricular inversion and arterial transposition creates a unique anatomic substrate that fosters subpulmonic left ventricular outflo...
Unruptured right sinus of Valsalva aneurysm that causes severe obstruction of the right ventricular outflow tract is extremely rare. We describe the case of a 47-year-old woman who presented with exertional dyspnea. Upon investigation, we discovered an unruptured right sinus of Valsalva aneurysm with associated right ventricular outflow tract obstruction and a supracristal ventricular septal de...
[1] Morell VO, Wearden PD. Aortic translocation for the management of transposition of the great arteries with a ventricular septal defect, pulmonary stenosis, and hypoplasia of the right ventricle. Eur J Cardiothorac Surg 2007;31:552—4. [2] Sayin OA, Ugurlucan M, Saltik L, Sungur Z, Tireli E. Modified Nikaidoh procedure for transposition of great arteries, ventricular septal defect and left ve...
Cross sectional echocardiographic studies were assessed prospectively in 58 infants in whom right ventricular outflow obstruction was subsequently shown angiographically. A subcostal cut was used to display simultaneously the short axis of the aortic root and the long axis of the right ventricular outflow tract. This facilitated the differentiation of the common right ventricular outflow tract ...
Echocardiographic studies have demonstrated that the characteristic anatomic defect in idiopathic hypertrophic subaortic stenosis (IHSS) is asymmetric septal hypertrophy (ASH). Although echocardiographic diagnosis of ASH is extremely sensitive, occasionally adequate echocardiograms cannot be obtained. Moreover, echocardiographic assessment of the extent of the underlying cardiomyopathic process...
THE RECENT advancement of cardiac surgery with the use of whole-body perfusion makes necessary an accurate anatomic diagnosis not only of the chief cardiac malformations for which the surgical procedure may be undertaken but of associated defects as well. The problems of diagnosis and surgieal management of the combination of a defeet of the intraventricular septum and aortic incompetence have ...
Two cases are reported in which complete transposition of the great vessels was associated with an unusual form of subpulmonic obstruction. In each case, redundant tricuspid valvular tissue protruded through a ventricular septal defect into the left ventricular outflow tract, producing severe obstruction to the outflow of blood from the left ventricle. The clinical course suggested the presence...
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morro...
Discrete subaortic membranes are rare congenital abnormalities which may cause hemodynamic consequences secondary to left ventricular outflow obstruction. It may present as an isolated abnormality or may accompany other congenital abnormalities such as ventricular septal defects and bicuspid aortic valve (BAV). Two dimensional (2-D) and recently three dimensional (3-D) echocardiography is used ...
