University Hospital Quironsalud Madrid offers advanced Balloon Atrial Septostomy using modern interventional cardiology techniques and individualized congenital cardiac care plans. Established in 2006, the ISO, JCI accredited hospital is located in Madrid, Spain and has 575 beds, providing comprehensive cardiac care for local and international patients.

Balloon Atrial Septostomy is a catheter-based procedure used to create or enlarge an opening between the atria to improve the mixing of oxygen-rich and oxygen-poor blood. It is most commonly performed in critically ill newborns with certain congenital heart defects where adequate blood mixing is essential for maintaining oxygen levels. During the procedure, a balloon-tipped catheter is passed through the existing atrial opening and inflated to enlarge the communication between the atria.
