Restenosis limits repeat balloon aortic valvuloplasty (BAV2). This study evaluated BAV2 indications and outcomes, finding it significantly reduces aortic stenosis gradients and improves valve area in symptomatic patients.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Valvular Heart Disease

Background:

  • Balloon aortic valvuloplasty (BAV) is a treatment for aortic stenosis.
  • Restenosis is a major limitation of BAV, necessitating evaluation of repeat procedures.
  • Understanding indications for a second BAV (BAV2) is crucial for patient management.

Purpose of the Study:

  • To determine the limitations and indications for performing a second balloon aortic valvuloplasty (BAV2).
  • To assess the effectiveness of BAV2 in patients experiencing restenosis after an initial BAV (BAV1).

Main Methods:

  • Retrospective analysis of patients undergoing BAV1 and BAV2.
  • Group A: Symptomatic patients undergoing BAV2 due to restenosis.
  • Group B: Patients undergoing systematic catheterization to evaluate hemodynamic restenosis after BAV1.

Main Results:

  • BAV2 significantly decreased the transvalvular gradient (P < 0.001) and increased aortic valve area (P < 0.001) in both groups.
  • Group A showed a reduction in gradient from 72 +/- 22 to 33 +/- 15 mm Hg and an increase in valve area from 0.56 to 0.85 cm2.
  • Group B showed a reduction in gradient from 68 +/- 15 to 33 +/- 15 mm Hg and an increase in valve area from 0.70 to 0.90 cm2.

Conclusions:

  • Repeat balloon aortic valvuloplasty (BAV2) is effective in improving hemodynamic parameters in patients with restenosis.
  • BAV2 can be considered a therapeutic option for selected patients experiencing restenosis after initial BAV.
  • Further research is needed to fully define the long-term outcomes and optimal patient selection for BAV2.
