What is Atrioventricular Septal Defect (AVSD)?
Atrioventricular Septal Defect (AVSD) is a congenital heart condition caused by abnormal development of the heart’s atrial and ventricular septa and the atrioventricular (AV) valves. It leads to abnormal communications between the heart chambers and improper valve function, which causes mixing of oxygen-rich and oxygen-poor blood.
AVSD presents in two forms:
- Complete AVSD – a single common AV valve and large holes between chambers
- Partial (or incomplete) AVSD – separate valves with defects in either atrial or ventricular septum
Key symptoms often appear in infancy and include poor feeding, fatigue, breathing difficulties, and failure to thrive. It is frequently associated with Down syndrome. Without treatment, AVSD can lead to heart failure, pulmonary hypertension, and long-term complications.
Treatment typically involves:
- Open-heart surgery to patch the septal defects and repair or divide the common valve
- Medication (prior to surgery) to manage symptoms like fluid retention or heart failure
Surgical repair is usually recommended between 3–6 months of age, with a high success rate (approx. 95%). Timely intervention is crucial to prevent irreversible damage to the heart and lungs.
Why Choose India for Atrioventricular Septal Defect (AVSD) Surgery?
India is a preferred destination for AVSD surgery due to its combination of advanced paediatric cardiac care and cost-effectiveness. Tier 1 hospitals like Fortis Escorts Heart Institute, Medanta–The Medicity, Apollo Hospitals (Delhi), and Max Super Speciality Hospital offer:
- Internationally trained paediatric cardiac surgeons and cardiologists
- Advanced diagnostics and surgical techniques, including 3D mapping and minimally invasive options
- High success rates, particularly for early paediatric interventions
- Dedicated international patient coordinators for visa, travel, and recovery planning
- Comprehensive post-operative support, including rehabilitation and cardiac follow-up
India’s affordability and clinical expertise make it a top choice for families seeking expert, life-saving treatment for congenital heart defects like AVSD.
