Congenital heart disease with ductal-dependent pulmonary circulation requiring a modified Blalock Thomas Taussig shunt (MBTTS) for palliation. These include defects such as pulmonary atresia, severe pulmonary stenosis, tricuspid atresia, and other single-ventricle or biventricular malformations that result in inadequate blood flow to the lungs and low oxygen levels after birth. The study focuses on infants and children who underwent MBTTS at Siriraj Hospital between 2010 and 2020. It aims to d
