Left pulmonary artery reconstruction using cryopreserved pulmonary homograft.

Abstract

In patients with univentricular heart, the Fontan procedure is the final palliation. This is usually staged. A systemic-to-pulmonary artery shunt is performed in the presence of episodes of cyanotic spells in the neonatal period or in some patients in infancy; a bidirectional superior cardiopulmonary anastomosis is preferred early in life. This is followed by the final Fontan palliation on an elective basis later. For an effective bidirectional superior cavopulmonary anastomosis and Fontan palliation, good-sized confluent pulmonary arteries (PAs) are mandatory in addition to favorable hemodynamic data. Patients with discontinuous PAs that are small in size present a surgical challenge at initial palliation as the one described in this report.
