Summary
This study presents a simplified percutaneous mitral dilatation technique using Inoue balloon, achieving significant mitral area increase with minimal complications. The method offers a safe, cost-effective, and comfortable alternative for mitral stenosis treatment.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Catheterization
Background:
- Mitral stenosis management often requires invasive procedures.
- Percutaneous mitral balloon valvuloplasty (PMBV) is an established treatment.
- A simplified, less invasive PMBV approach is desirable for wider application.
Purpose of the Study:
- To evaluate the efficacy and safety of a simplified percutaneous mitral dilatation technique.
- To assess outcomes in a large cohort including diverse patient subgroups.
- To determine the feasibility of this method in routine clinical practice.
Main Methods:
- A simplified percutaneous mitral dilatation using Inoue balloon with progressive diameter inflations.
- Echographic control was utilized, avoiding arterial procedures.
- A total of 936 procedures were performed between 1997 and the study period.
Main Results:
- Significant increase in mitral area from 1 +/- 0.2 cm2 to 2.1 +/- 0.1 cm2.
- Low incidence of surgical mitral regurgitation (3 cases).
- Procedure time averaged 19 +/- 9 min, fluoroscopy time 6.4 +/- 3.3 min, with 1-day hospitalization in 97% of patients.
Conclusions:
- The simplified percutaneous mitral dilatation is a safe and effective technique.
- It offers significant patient benefits including reduced cost (approx. 20%) and improved comfort.
- The technique's simplicity and positive outcomes suggest a promising future for treating mitral stenosis.
