Dexeus University Hospital is a trusted healthcare provider for Balloon Atrial Septostomy, offering emergency and minimally invasive congenital heart interventions supported by experienced pediatric cardiologists, interventional cardiologists, neonatal specialists, advanced catheterisation laboratories, and intensive-care teams. Established in 1973, the JCI- accredited hospital is situated in Barcelona, Spain and has 200 beds.

Balloon Atrial Septostomy creates or enlarges an atrial communication to improve the movement and mixing of blood within the heart. This can be particularly important in congenital heart defects where adequate interatrial blood flow is necessary for oxygen delivery to the body. The procedure may provide temporary stabilization while the child is prepared for definitive surgical or catheter-based treatment. The medical team evaluates the underlying heart defect, oxygenation, circulation, and overall clinical condition before intervention.
