Total anomalous pulmonary venous connection (TAPVC) is an uncommonly encountered cyanotic congenital heart disease characterized by anomalous drainage of the pulmonary veins. Concomitant venous anomalies are rarely found in these patients. We present a case of an infra-cardiac TAPVC with an intrahepatic portosystemic shunt, where a vascular channel was seen between the middle hepatic vein and the left branch of the portal vein with fusiform dilatation of the latter, diagnosed on computed tomography angiography.

Article Synopsis
  • Surgical repair of obstructed total anomalous pulmonary venous connection (TAPVC) in infants is high-risk, and a study was conducted to evaluate surgical risk factors and outcomes at a single center.
  • The study included 41 infants with obstructed TAPVC, revealing a 19.5% in-hospital mortality rate, with significant risk factors being age under 30 days and the need for pre-operative ventilation.
  • Follow-up showed reasonable surgical outcomes, with no deaths among the survivors, although some patients developed pulmonary vein obstructions that required additional interventions.

Total anomalous pulmonary venous connection (TAPVC) is a critical congenital heart disease which is often missed on prenatal echocardiography because of the decreased pulmonary blood flow in fetal life. Improvement in technology has resulted in increasing prenatal diagnosis of this condition. We report a foetus with infra cardiac TAPVC in whom prenatal diagnosis was facilitated by the use of STIC technology.

Even today, when the surgical outcome of congenital heart disease in the neonatal period has improved, the prognosis for heterotaxy syndrome and functional single ventricle complicated with total anomalous pulmonary venous connection (TAPVC), especially the infra-cardiac type, is catastrophic. We describe a strategy that combines percutaneous ductus venosus (DV) stent placement and occlusion after TAPVC repair to ensure survival from initial surgery to bidirectional cavopulmonary shunt (BCPS) procedure and facilitate subsequent treatment. Three consecutive patients with heterotaxy syndrome and functional single ventricle complicated by infra-cardiac TAPVC treated with our own strategy were retrospectively studied.

A 28-year-old male with infra-cardiac totally anomalous pulmonary venous connection (TAPVC) repaired as new-born presented in adulthood with right heart strain and very large left atrium to portal vein vessel. Residual connections from pulmonary veins to systemic circulation are believed to represent persistent 'vertical veins' (VV) not ligated at the time of the initial surgery. In our patient, since endovascular occlusion was not judged suitable, the anomalous vessel was surgically ligated and resected.
