    Abstract:
    OBJECTIVE: Pulmonary venous obstruction (PVO), the major postoperative complication in patients with infracardiac total anomalous venous connection (TAPVC), compromises the surgical outcomes of TAPVC repair. Here, we report our experience using a right-sided approach to the left atrium to repair this anomaly variant. METHOD: Eleven patients with infracardiac TAPVC underwent this surgical modification from September 2005 to December 2009. After a medium sternotomy, bicaval venous cannulation was performed for cardiopulmonary bypass (CPB). By adequate exposure of the surgical field, incision of the left atrium was located and anastomosed to the corresponding incision in the pulmonary venous confluence through the right side. Medical records consisting of preoperative and postoperative data were retrospectively reviewed to analyze the efficiency of this strategy. RESULTS: Total correction was achieved in all 11 patients and there were no operative deaths. Postoperative low cardiac output persisted in six patients (54.5%), including five patients with preoperative PVO. No late deaths were noted in a mean follow-up of 26.7 months (range, 1 to 51 months). Both residual atrial shunt and severe anastomotic obstruction were excluded by transthoracic echocardiography. Moderate residual obstruction was confirmed in one patient. At the end of the follow-up, all patients had normal biventricular function and were in New York Heart Association (NYHA) Functional Class I. CONCLUSION: The right-sided approach for repair of infracardiac TAPVC contributes to produce favorable outcomes. This modified technique is useful for enhancing exposure during surgical repair and providing adequate patent anastomosis.
