Summary

Balloon aortic valvuloplasty offers encouraging immediate and intermediate results for aortic stenosis, with minimal complications. Further research is needed to confirm long-term effectiveness and refine techniques for pediatric patients.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pediatric Cardiology

Background:

  • Balloon aortic valvuloplasty (BAV) has been utilized since 1983 for aortic stenosis.
  • It is applied in infants, children, and adults.
  • BAV shows promising immediate and intermediate-term outcomes.

Purpose of the Study:

  • To review the effectiveness and safety of balloon aortic valvuloplasty.
  • To compare BAV outcomes with surgical valvotomy.
  • To identify indications and potential complications of BAV.

Main Methods:

  • Review of existing literature on balloon aortic valvuloplasty.
  • Analysis of immediate and intermediate-term results.
  • Evaluation of complication rates and follow-up data.

Main Results:

  • BAV demonstrates encouraging results with minimal complications, comparable to surgical valvotomy.
  • Key indications include gradients >80 mmHg or >50 mmHg with symptoms/ECG changes.
  • Restenosis is a concern, necessitating risk factor management; Echo-Doppler is vital for follow-up.

Conclusions:

  • BAV is a viable option for aortic stenosis, with potential for subaortic stenosis treatment.
  • Long-term (5-10 year) follow-up data is crucial for assessing durability.
  • Technique refinement and system miniaturization are needed to enhance safety and efficacy, especially in pediatric cases.
