Anesthesia Challenges in Patent Ductus Arteriosus Stenting for Congenital Heart Disease

389 The Editor, Ductus arteriosus is communication present between pulmonary artery and proximal descending aorta. It is essential in fetal life to shunt blood from right ventricle bypassing the underdeveloped lungs. It closes functionally soon after birth and anatomically by days to few weeks. Ductal patency may be lifesaving in few cyanotic congenital heart diseases to maintain pulmonary blood flow. Typical duct‐dependent lesions include pulmonary and tricuspid atresia, critical pulmonary stenosis, and tetralogy of Fallot with pulmonary stenosis. These patients require either prostaglandin infusion for maintaining ductal patency or palliative shunt surgeries such as Blalock Taussig (BT) shunt. Patent ductus arteriosus (PDA) stenting is an attractive, less invasive procedure and equally effective as BT shunt.[1]
