Closure of (PDA) Patent Ductus Arteriosus by Pericardial Patch through Pulmonary Artery Incision, Heart Beating with Stand-By Cannulated Heart: A Case Report

Echocardiography revealed significant large patent ductus arteriosus 10 mm in diameter with bidirectional shunt due to high pulmonary pressure. The left ventricle within normal size with good contractility. The pulmonary artery is dilated with secondary pulmonary regurgitation, right ventricle is dilated, and right ventricle pressure is elevated with flattening of the interventricular septum and secondary tricuspid regurgitation. Due to the age of patients and large size of PDA, the best approach was sternotomy not left thoracotomy. After exploring the real site and size of PDA, which was deep and short neck, we decided the best approach was through pulmonary incision and closed by pericardial patch with intentionally leaving shunt.
