SummaryMalfunctioning of the left atrioventricular valve has always been, and remains, the major incremental risk factor in the repair of atrioventricular septal defect. Now that the cardiac surgeon has ample time to assess the anatomy and function of the left valve, results have improved, but are still less than ideal. On the presumption that the anterior leaflet of the mitral valve is “cleft” in this anomaly, it used to be common practice to close the “cleft”. Currently, a substantial number of surgeons employ this technique, often irrespective of the individual anatomy, and in the majority of cases with success.

Atrioventricular septal defects represent a class of congenital cardiac malformations that vary in presentation and management strategy depending upon the severity of the particular lesions present. We present the case of a premature neonate who had a partial atrioventricular septal defect and an accessory mitral (or left atrioventricular) valve leaflet. The latter caused severe left ventricular outflow tract obstruction and severely depressed left ventricular function. We found only one other report of this atrioventricular valve abnormality in association with atrioventricular septal defect. To our knowledge, our patient (at a body weight of 1,800 g) is the smallest to survive corrective surgery of an accessory mitral valve leaflet with severe left ventricular outflow tract obstruction. In addition to our patient's case, we discuss the relevant medical literature.
