Summary
Percutaneous mitral valvuloplasty is effective for mitral stenosis. This procedure safely improved valve area and reduced pressure gradients in selected patients, even those with less ideal conditions.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Mitral stenosis is a significant valvular heart disease.
- Percutaneous mitral valvuloplasty (PMV) offers a less invasive treatment option.
Purpose of the Study:
- To evaluate the efficacy and safety of Inoue technique percutaneous mitral valvuloplasty.
- To assess outcomes in patients with varying degrees of mitral stenosis severity and prior interventions.
Main Methods:
- 83 patients underwent Inoue technique PMV between May 1991 and July 1992.
- Echocardiographic scores (Wilkins' criteria) were used for patient selection (ideal: <= 8).
- Outcomes assessed included mitral valve area, pressure gradients, and complications.
Main Results:
- Successful treatment in 97.6% of patients; 2 required surgery for severe mitral regurgitation.
- Significant increase in mitral valve area (1.1 to 2 cm2) and decrease in pressure gradient (16 to 6 mmHg).
- Patients with prior surgery had less mitral valve area increase; those with echo-score > 8 had more regurgitation.
Conclusions:
- PMV is an effective and safe treatment for selected mitral stenosis patients.
- The technique yields satisfactory results even in cases with non-ideal clinical or valvular conditions.
- Good immediate and mid-term outcomes support PMV as a viable therapeutic option.
