Extracardiac Fontan with direct cavopulmonary connections: midterm results

Extracardiac Fontan with direct cavopulmonary connections: midterm results OBJECTIVESThe aim of this study was to analyse the midterm results following superior and inferior direct cavopulmonary connections (DCPC) to create a Fontan circulation in patients with functionally univentricular hearts.METHODSA retrospective review of patients operated on between January 2005 and December 2011 was carried out.RESULTSThirty consecutive patients who underwent this type of operation were retrospectively reviewed. There were 18 (60) males and 12 (40) females, with a median age of 69 months (range 16150 months) and median weight of 23 kg (range 1146 kg). Aortic cross-clamping was used in 10 patients, with a median cross-clamp time of 40 min (range 2399) and a median cardiopulmonary bypass (CPB) time of 135 min (range 76179 min). The remaining 20 patients were operated on without aortic cross-clamping. Their median CPB time was 104 min (range 78139 min). Fenestration was performed in 16 patients. The associated intracardiac procedures were performed in 10 patients. The follow-up period ranged from 2 months to 6 years. Operative mortality and late mortality after discharge was zero. The major postoperative complications included supraventricular tachycardia in one patient, oliguria and peritoneal dialysis in one and chest drainage (>30 ml/day) persisting >7 days in five (20).

There were 18 (60) males and 12 (40) females, with a median age of 69 months (range 16150 months) and median weight of 23 kg (range 1146 kg).
