Summary
Percutaneous closure of interventricular septal defects (IVSD) using Amplatzer prostheses is a complex but safe and effective alternative to surgery. This initial experiment shows promising results for selected patients with muscular and perimembranous IVSD.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Devices
Background:
- Interventricular septal defects (IVSD) are congenital heart abnormalities requiring treatment.
- Traditional surgical closure can be invasive.
- Percutaneous closure offers a less invasive alternative.
Purpose of the Study:
- To evaluate the initial experience with percutaneous closure of IVSD using Amplatzer prostheses.
- To specifically assess the efficacy and safety in perimembranous IVSD (PMIVSD).
Main Methods:
- Eleven patients underwent percutaneous closure of IVSD.
- Six patients had PMIVSD, and five had muscular IVSD (MIVSD).
- Transthoracic echocardiography (TTE) was used for patient selection.
Main Results:
- Successful implantation of Amplatzer prostheses in all patients.
- No complications in the MIVSD group; one migration and one transient atrioventricular block in the PMIVSD group.
- The procedure demonstrated technical feasibility and initial success.
Conclusions:
- Percutaneous closure of IVSD with Amplatzer devices is a safe and efficient option for selected patients.
- The procedure requires specialized centers due to its technical complexity.
- It presents a viable alternative to conventional surgical treatment for IVSD.
