Challenging ASD Device Closure with Deficient IVC Rim
Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital in Rajkot, recently completed a technically demanding transcatheter atrial septal defect (ASD) closure — a case that highlights the advanced skills required in complex structural heart interventions.
About the Patient
A 26-year-old woman came in with a large secundum atrial septal defect (ASD). This is a hole in the wall (septum) between the two upper chambers of the heart. In her case, the challenge was even greater — the inferior vena cava (IVC) rim, which is the tissue edge near the large vein that brings blood from the lower body to the heart, was deficient (too thin or absent). This rim is important because it helps hold the closure device in place.
What Is Transcatheter ASD Closure?
ASD closure without open-heart surgery is done by passing a thin, flexible tube (catheter) through a vein in the leg up to the heart. A specially designed occluder device is then guided through the catheter and positioned to seal the hole. The patient avoids major surgery, recovers faster, and returns home sooner.
Why Was This Case Complex?
A deficient IVC rim makes it very difficult to anchor the closure device safely. Without adequate rim tissue on one side, the device can shift or fail to sit correctly. In this case, careful planning and precise technique were essential.
- Defect size: Large secundum ASD
- Device used: 42 mm occluder — selected carefully based on defect size and the adequacy of the remaining rims
- Approach: Transcatheter (no open-heart surgery)
Key Takeaway
This case is a clear example of why operator experience and sound clinical judgment matter so much in structural heart interventions. Not every ASD can be closed the same way. High-risk cases like this one require advanced catheterisation skills, patience, and thorough pre-procedure planning.
Successful outcomes in complex ASD closures depend on the right expertise — and the right team.
If you or a family member has been diagnosed with ASD or any other structural heart condition, please consult a qualified interventional cardiologist for a proper evaluation and personalised advice. You can book a consultation with Dr. Nikhila Pachani at Backbone Medicity Hospital, Rajkot.
