Ventricular septal defect with aneurysm of the membranous septum and a parachute mitral valve. Echocardiographic findings.

The echocardiographic findings in a case of ventricular septal defect with aneurysm of the membranous septum and a parachute mitral valve, are analyzed. An abnormal linear echo was recorded within the left ventricular outflow tract and in the aortic root, and in close relationship with the tricuspid valve. No abnormal systolic echoes were seen neither anterior to the interventricular septum nor in the right ventricular outflow tract. The hypothesis that a parachute m. An abnormal linear echo was recorded within the left ventricular outflow tract and in the aortic root, and in close relationship with the tricuspid valve. No abnormal systolic echoes were seen neither anterior to the interventricular septum nor in the right ventricular outflow tract. The hypothesis that a parachute m. An abnormal linear echo was recorded within the left ventricular outflow tract and in the aortic root, and in close relationship with the tricuspid valve. No abnormal systolic echoes were seen neither anterior to the interventricular septum nor in the right ventricular outflow tract. The hypothesis that a parachute mitral valve without significant obstruction at the infravalvar level is not distinguishable echocardiographically from a normal mitral valve, is confirmed in this patient. This case example further clarifies the origin of the anterior cusp echo of the aorta, due to the close proximity between the membranous septum and the right aortic cusp.
