Apicocaval juxtaposition (ACJ) may complicate the selection of conduit route in patients with single ventricles when total cavopulmonary connection (TCPC) is performed. We reviewed our experience of pathway selection and evaluated the clinical results. Of 128 patients who underwent TCPC at our hospital between January 2009 and April 2016, 31 with ACJ were included in this study. In 24 patients, the conduit was placed between the inferior vena cava (IVC) and the ipsilateral pulmonary artery. To avoid compression of the conduit and pulmonary veins in 5 patients, the conduit was placed between the IVC and the contralateral pulmonary artery. In 2 patients, the tube graft was anastomosed with the IVC orifice within the atrium, then guided through the atrial free wall and anastomosed with the contralateral pulmonary artery outside the heart (intra/extracardiac Fontan). Patient demographics were compared with those of patients without ACJ. The mean age and body weight at surgery were 58.5 ± 32.4 months and 16.2 ± 6.0 kg, respectively. The mean postoperative pulmonary artery pressure was 15 ± 3 mm Hg. The postoperative data did not differ significantly from that of patients without ACJ who underwent extracardiac TCPC. One patient died of overwhelming infection. The mean follow-up was 17.5 ± 15.4 months (range, 1-65 months). There were no conduit-related early or late complications. TCPC in patients with ACJ can be performed with excellent early and midterm results. The route between the IVC and the ipsilateral pulmonary artery is our preference.
