At Medipol Bahçelievler Hospital, Balloon Atrial Septostomy is performed using specialized catheter-based cardiac techniques and comprehensive pre-procedure assessment. Established in 2022, this JCI accredited hospital in Istanbul, Turkey has 441 beds and offers advanced pediatric and congenital interventional cardiology services.

Balloon Atrial Septostomy may be considered for newborns with certain cyanotic congenital heart conditions in which restricted blood flow between the atria results in inadequate mixing of blood. A catheter with a small balloon at its tip is introduced through a blood vessel and guided into the heart. The balloon is passed through the atrial opening, inflated, and withdrawn to enlarge the opening and improve blood mixing. Echocardiography and other cardiac imaging techniques help guide the procedure.
