Due to therapid development in this field, it is the therapy of choice in current era. As most of PDAs have conical shape, Amplatzer PDA occluders were designed to fit into these ducts. Closure of a short duct by this device may cause stenosis due to the device protrusion into the pulmonary artery.展开更多
