OBJECTIVES: The 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.
METHODS: A retrospective review of patients operated on between January 2005 and December 2011 was carried out.
RESULTS: Thirty 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 16-150 months) and median weight of 23 kg (range 11-46 kg). Aortic cross-clamping was used in 10 patients, with a median cross-clamp time of 40 min (range 23-99) and a median cardiopulmonary bypass (CPB) time of 135 min (range 76-179 min). The remaining 20 patients were operated on without aortic cross-clamping. Their median CPB time was 104 min (range 78-139 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%). One patient developed sinus bradycardia in association with sinus pauses 2 months after discharge. One patient developed pericardial effusion 1 month after discharge. A computational fluid dynamic study was performed in one patient. The computational fluid dynamic study showed that DCPC may have a better power efficiency.
CONCLUSIONS: Superior and inferior DCPCs to create a Fontan circulation in appropriately selected patients with functionally univentricular hearts can be performed with a low risk and a low rate of reinterventions. The midterm results are favourable.
