Percutaneous closure should be given a chance in patent ductus arteriosus with severe pulmonary hypertension

Angiographic determination of morphological structure plays an important role in device selection during transcatheter patent ductus arteriosus (PDA) closure1. PDA can be closed surgically and percutaneously1-4. Unless irreversible pulmonary vascular disease develops, it is recommended to close the defect to protect the patient from possible infective endocarditis, even if the shunt is small2. However, in patients with high irreversible pulmonary arterial pressure, response to selective vasodilator therapies for pulmonary arterial hypertension should be reevaluated for closure2-3. Today, the most commonly used methods for PDA closure are coil and PDA closing devices (exp ADO1 and ADO-II)2,3.
