[Recurrent surgery for pulmonary venous obstruction after total correction of TAPVC (IIb)]

A 15-months-old boy underwent the intra-cardiac repair with a glutaraldehyde-preserved equine pericardium for total anomalous pulmonary venous connection (Darling's type IIb). Because of rapidly progressive dyspnea, tachycardia and respiratory acidosis, he required emergent reoperation at 234 postoperative days. The pseudointima was thickened heavily and detached from glutaraldehyde-preserved equine pericardium. New channel was created with a piece of EPTFE sheet to prevent obstruction of pulmonary venous flow. However, about four months after second surgery, cough and tachycardia progressed again remarkably. Intra-atrial channel was obstructed between EPTFE sheet and the partition from pulmonary venous orifice to the atrial septal defect in the third operation. The intra-atrial channel was enlarged by cut-back method using EPTFE sheet again. His postoperative hemodynamics were satisfactory
