Summary
Rapid ventricular pacing effectively stabilizes balloons during balloon aortic valvuloplasty in pediatric patients. This technique improves outcomes for aortic valve stenosis, reducing complications like aortic regurgitation.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Aortic valve stenosis (AS) is a significant congenital heart defect in children.
- Balloon aortic valvuloplasty (BAV) is a common treatment for AS.
- Achieving balloon stability during BAV is crucial for procedural success and minimizing complications.
Purpose of the Study:
- To evaluate the efficacy and safety of rapid ventricular pacing (RVP) during BAV.
- To determine if RVP can enhance balloon stability and reduce procedural risks.
Main Methods:
- A prospective study involving ten pediatric patients with AS undergoing BAV.
- Placement of a bipolar pacing catheter in the right ventricle.
- RVP initiated at 150 bpm, gradually increased to achieve a 50% drop in systemic pressure before balloon inflation.
Main Results:
- RVP successfully achieved balloon stability in all patients during BAV.
- Mean systolic gradients decreased significantly post-BAV (68.5±20 mmHg to 19.7±8.3 mmHg).
- Only one patient developed mild aortic regurgitation, suggesting a potential decrease in complications.
Conclusions:
- Rapid ventricular pacing is an effective and safe adjunct for stabilizing balloons during BAV.
- This method may reduce the incidence of aortic regurgitation following BAV in pediatric patients.
