Werndale Hospital provides specialised PDA Closure with a focus on precise ductal closure, advanced pediatric cardiac techniques, and individualised post-treatment care. Established in 1991, the accredited hospital is located in Carmarthen, United Kingdom and operates 19 beds, with modern cardiac catheterisation, surgical, and critical-care infrastructure.

PDA Closure can prevent the effects of persistent abnormal blood flow between the aorta and pulmonary artery in appropriately selected patients. The treatment approach depends on the PDA's size, shape, location, the patient's age, and associated heart conditions. A detailed evaluation using echocardiography and other cardiovascular investigations helps the cardiac team determine whether transcatheter device closure or surgical closure is appropriate and plan the patient's follow-up care.
