A case of direct congenital Gerbode defect misdiagnosed as left to right
ventricle shunt and literature review
Abstract
The direct congenital Gerbode defect was a rare type of ventricular
septal defect (VSD) causing a communication between the left ventricle
(LV) and right atrium (RA). In this case, only LV-to-right ventricle
(RV)shunt was found preoperatively. But in operation, the defect was
located at the interventricular septum between the tricuspid (TV) and
mitral valves (MV) where the shunt was from LV to right atrium (RA) and
septal TV dysplasia was found. The shunt might be LV-to-RA and the blood
flow into the RV through the defect of TV. This article discussed why
the preoperative ultrasound misdiagnosed this type of shunt and reviewed
the literature of Gerbode defect.
