Journal of Cardiology
|December 13, 1997
Summary
This study evaluated catheter techniques for transcatheter closure of ventricular septal defects (VSDs). The Judkins right coronary catheter proved most effective for crossing various VSD types, aiding in VSD closure procedures.
Area of Science:
- Cardiology
- Interventional Cardiology
- Pediatric Cardiology
Background:
- Transcatheter closure of ventricular septal defects (VSDs) is a developing field.
- Optimal catheter selection is crucial for successful VSD closure procedures.
Purpose of the Study:
- To assess the success rate of different catheter tips for crossing various VSD types.
- To identify the most suitable catheter for transcatheter VSD closure.
Main Methods:
- Retrospective analysis of 18 consecutive patients with diverse VSD types.
- Evaluation of catheter passage (angiographic balloon, Judkins right coronary) antegradely or retrogradely.
- Defect characterization using two-dimensional echocardiography.
Main Results:
- Catheter passage was successful in 16 out of 18 patients (89%).
- The Judkins right coronary catheter demonstrated the highest success rate for crossing VSDs.
- Failure to cross occurred in two patients with small defects (1.0-2.0 mm).
Conclusions:
- The Judkins right coronary catheter is the preferred choice for crossing VSDs during transcatheter procedures.
- Successful VSD crossing is achievable in most VSD types with appropriate catheter selection.
- Further research can optimize transcatheter VSD closure techniques.
