Abstract
Severe regurgitation of the atrio-ventricular valve and borderline pulmonary vascular resistance are risk factors for failure of univentricular repair. We believe that fenestration in the Fontan pathway plays an important role in avoiding postoperative catastrophes- immediate and late, in such high-risk substrates. Rarely, the intra-operative circumstances compel the surgeon to opt for an unconventional method of fenestration. We report an interesting case of high-risk univentricular repair, had previously undergone pulmonary artery banding and bidirectional Glenn shunt, who now required a simultaneous repair of the regurgitant atrio-ventricular valve compelling the creation of an unconventional fenestration during Stage III palliation.

This is a sagittal view of contrast-enhanced computerized tomography scan showing widely patent superior cavo-pulmonary connection (short arrow) and banded main pulmonary artery (long arrow). One can appreciate the absence of interventricular septum, and the tiny collateral vessels around the heart. Ao Aorta; MPA Main pulmonary artery; SV Single ventricle; SVC Superior vena cava.

) This is an intraoperative photograph taken from the head-end of the patient, showing the heart in diastolic cardioplegic arrest and ascending aorta cross-clamped. The right atrium is opened and retracted with stay sutures. The right atrioventricular (AV) valve is being repaired (arrow). Pericardial adhesions can be noted.

This is another intraoperative photograph taken from the right side of the patient, showing the extracardiac expanded polytetrafluoroethylene conduit anastomosed to the distal open end of the inferior vena cava. Kreutzer’s technique of fenestration (arrow) has been performed, wherein the proximal open end of the inferior vena cava is sutured to an opening made in the adjacent part of the extracardiac Fontan conduit.

Postoperative echocardiography (2-dimensional and colour doppler) in short axis view showing well-functioning and competent both atrioventricular (AV) valves and good flow in the Kreutzer’s fenestration communicating to the Fontan conduit. The absence of interventricular septum amounting to a single ventricle also can be appreciated in this view
