Ventricular Septal Defect (VSD) is a congenital heart condition characterized by a hole in the wall separating the two lower chambers of the heart (ventricles). This defect allows oxygen-rich blood to mix with oxygen-poor blood, leading to increased blood flow to the lungs and overload of the left side of the heart.
VSD device closure is a catheter-based, minimally invasive procedure that closes the defect without open-heart surgery, allowing faster recovery and excellent outcomes.
VSDs are classified based on their location within the ventricular septum. Among these, muscular VSDs are best suited for transcatheter device closure, while perimembranous VSDs are the most common overall.
- Perimembranous VSD – most common type
- Muscular VSD – best suited for device closure
- Subpulmonic / Outlet VSD
- Inlet VSD
- Large left-to-right shunt causing heart overload
- Early, reversible pulmonary hypertension
Who Needs VSD Device Closure?
VSD device closure is recommended in patients who develop symptoms or complications due to significant blood flow across the defect.
Indications include failure to thrive in infants, frequent respiratory infections, significant left-to-right shunt, left heart chamber enlargement, early pulmonary hypertension, and a history of infective endocarditis.
The procedure is done under general anesthesia, especially in children. A catheter is inserted through the femoral vein or artery, the defect is crossed using guidewires, and a double-disc nitinol occluder device is deployed to seal the VSD.
The procedure duration is usually between 60 and 120 minutes, depending on the size and location of the defect.
Most patients stay in the hospital for 1–2 days for monitoring and are discharged once stable.
It avoids open-heart surgery, leaves no surgical scar, reduces hospital stay, allows faster recovery, and prevents long-term complications such as heart failure and pulmonary hypertension.
