Expanded Polytetrafluoroethylene Patching for Recurrent Pulmonary Venous Obstructions.

Recurrent postoperative pulmonary venous obstruction after total anomalous pulmonary venous connection repair is a challenging complication. Here, we present such a case that required 4 reoperations, focusing on a sutureless method with an expanded polytetrafluoroethylene patch for the fourth reoperation. The use of artificial patch materials to reconstruct the atrial septum and neoatrial roof could be a promising alternative approach of this method to expand its applicability.
