An alternative technique for completion of the total cavopulmonary connection.

Abstract

Total Cavopulmonary connection (Fontan) is the final palliation for patients with a functionally univentricular heart. This is commonly accomplished after a prior bidirectional Glenn on cardiopulmonary bypass (CPB) with separate cannulation of the aorta, superior vena cava (SVC), and inferior vena cava. We describe an alternative technique of Fontan completion that eliminates the need for cannulation and dissection of the SVC, and pulmonary artery dissection. Between January and October 2018, 17 patients underwent completion Fontan using an alternate technique at our institute. All operations were conducted on CPB at normothermia without cannulating the SVC RESULTS: Mean CPB time was 60 ± 16.8 minutes (range, 39-102 minutes). There were no early deaths. Mean postoperative Fontan pressures were 15.6 ± 1.2 mm Hg with no gradient between the SVC and IVC pressures. Mean duration of hospital stay was 15.6 ± 3.6 days (range, 10-22 days). No patient developed phrenic nerve paresis or palsy. Completion without cannulating the SVC is simple, reproducible, and easy to teach. It avoids the disadvantages associated with routine techniques.
