Patent Ductus Arteriosus and the Nit-Occlud PDA Device

摘要

A twelve-month-old infant is followed with a continuous murmur, and echocardiographic confirmation of a Patent Ductus Arterosus (PDA). There is left atrial and left ventricular enlargement, normal right-sided pressures, runoff from the abdominal aorta, and transcatheter closure is recommended as spontaneous closure is unlikely beyond this age. The patient weighs 8.5kg. Access to the femoral artery is made with a 4F sheath, and to the femoral vein with a 5F sheath.
