A supramitral ring is a rare cause of mitral stenosis, while an isolated mitral valve cleft is a rare cause of congenital mitral regurgitation. Fortunately, both the lesions are known to have good outcomes after surgical correction. Although each is known to be associated with a variety of other structural heart defects, their coexistence has not been reported previously. We report a case of a three- and half-year-old boy detected to have a rare combination of supramitral ring producing severe mitral stenosis with a coexisting cleft in the anterior leaflet of mitral valve causing severe mitral regurgitation. The patient underwent successful surgical repair with resolution of both mitral stenosis and regurgitation.

In this study, we present the case of a neonate with obstructed infracardiac total anomalous pulmonary venous connection with severe pulmonary hypertension and a patent ductus arteriosus with right-to-left shunting. The patient had an unusual finding of pandiastolic flow reversal in the upper descending thoracic aorta. He underwent emergency surgical re-routing of the pulmonary veins to the left atrium, and postoperative echocardiography showed disappearance of the descending aortic flow reversal. We hypothesise that in severely obstructed total anomalous pulmonary venous connection the left ventricular output may be extremely low, resulting in flow reversal in the descending aorta.
