Abstract
|
|
|
Congenital diverticula of the cardiac ventricle have been reported as arising either from the left ventricle or, rarely from both ventricles. A diverticulum arising from the right ventricle alone is very rare. Furthermore the diverticulum
associated
with double chambered right ventricle was extremely rare.
We experienced a 62 years old female of double chambered right ventricle combined with congenital right ventricular true diverticulum. She had complained intermittent chest pain and mild dyspnea on exertion during 8 months. The chest X-ray and
chest CT
showed protruded abnormal density at anterolateral side of right ventricular outflow tract.
Preoperative angiography demonstrated a double chambed right ventricle and a right ventricular diverticulum.
In operative finding, there was found a anomalous muscle band, dividing the right ventricle into an inflow and outflow portion, and a 5x6cm sized right ventricular diverticulum arised from conus region with a stenotic orifice of 1.5cm in
diameter.
The
diverticulum was open toward the infundibulum, and its orifice was approximately 1 cm in diameter. On treatment, the diverticulum orifice was closed directly and the abnormal muscle band was resected in order to widen the right ventricular
outflow
tract. The postoperative result was satisfactory and good without specific complications.
