Introduction:

Percutaneous balloon mitral valvuloplasty has flourished as a mainstream therapy (mostly in developed countries) for treating patients with medical indication and those suffering from rheumatic mitral stenosis. This procedure is performed at the Cardiocentro in Santiago de Cuba since July 2008.

Objectives:

To describe the results of percutaneous balloon mitral valvuloplasty in the study participants.

Methods:

A descriptive, single-centered and observational study including 91 patients treated by this procedure was conducted at the Cardiocentro in Santiago de Cuba from July 2008 to June 2019. Clinical/epidemiological, echocardiographic and hemodynamic variables were assessed, as well as immediate procedure outcomes.

Results:

Young individuals (60.4% between 15-44 years), female (86.8%), with a history of rheumatic fever (48.4%), NYHA (New York Heart Association) functional class III (64.8%) and sinus rhythm (86.8%) predominated. An average increase in valve area of over double (0.99 vs. 2.12 cm2) the initial value and a reduction in atrial pressure of more than 50% (25 vs. 11.76 mmHg) was achieved; thus evidencing that the treatment was effective in 95.6% of the patients. A significant association (Fisher Test ≤ 0.05) was identified between Wilkins score ≤ 8 and satisfactory outcome of the procedure.

Conclusions:

The results of percutaneous balloon mitral valvuloplasty in the medical center were successful and consistent with those achieved nationally and internationally.
