Choosing IRCCS Policlinico San Donato for Balloon Atrial Septostomy gives patients access to experienced pediatric cardiac specialists, advanced echocardiography and catheterization systems, neonatal intensive care, and structured post-procedure monitoring. Established in 1969, the SSN accredited hospital in milan, Italy has 430 beds and provides specialized congenital heart disease services.

Balloon Atrial Septostomy is generally performed under sedation or anaesthesia appropriate to the infant's condition. The balloon catheter is introduced through a vascular access point and carefully advanced into the heart under imaging guidance. After the balloon is positioned across the atrial opening, it is inflated and withdrawn to enlarge the communication. Following the procedure, the infant is closely monitored for oxygenation, heart rhythm, bleeding, vascular complications, and changes in cardiovascular status while further treatment is planned.
