[Double chamber right ventricle. About 3 cases].
The double chambered right ventricle is a rare congenital abnormality. It creates an obstacle for the right ventricular ejection. The cardiac ultra sonography examination allows the diagnosis in most majority of cases. The angiography is performed in difficult cases. We report 3 cases of infundibular stenosis with normal interventricular septum. The diagnosis was suspected for the 3 cases by the constellation of clinical findings pointing to systolic murmur over the precordium, and the electrocardiography showing right ventricular hypertrophy. It is confirmed by the echocardiogram and the hemodynamic exploration with a trans stenotic gradient evaluated at 72,80 and 80mmHg. The 3 patients underwent surgery and had all good post operative follow up. These 3 observations allow us to recall the epidemiological, embryological, clinical and echocardiographic particularities of pure infundibular stenosis and to determin the adequate treatment and the prognosis.
