Abstract
Background/aimThis study aimed to evaluate the effect of successful percutaneous mitral balloon valvuloplasty (PMBV) on left ventricular systolic functions using strain and strain rate echocardiography in moderate–severe mitral stenosis (MS) patients with normal left ventricular systolic function confirmed by conventional echocardiography. Materials and methodsPatients with moderate–severe MS who had undergone successful PMBV were included. Conventional echocardiographic parameters were evaluated before and after PMBV. Peak systolic strain and strain rate values of basal, mid, and apical segments of the left ventricular anterior, inferior, septum, and lateral walls were determined. ResultsAfter PMBV, significant decreases were determined in the peak and mean gradients of the mitral valve and pulmonary artery pressure, but a significant increase in the mitral valve area. Significant increases (improvement) were determined in the peak systolic strain and strain rate in the basal, mid, and apical segments of the left ventricular septum, lateral, anterior, and inferior walls and in the left ventricular global peak systolic strain (–17.32 ± 0.58% vs. –12.38 ± 1.06%) and strain rate (–1.65 ± 0.07 vs. –1.22 ± 0.12). ConclusionStrain and strain rate echocardiography can be used for quantitative evaluation of the effect of PMBV on the left ventricular systolic functions in moderate–severe MS patients.

Summary
Mitral stenosis (MS) is a valvular heart disease that remains as an important cause of morbidity and mortality worldwide, in developing countries. It generally appears as a late term complication of acute rheumatic fever [1]. Mitral stenosis leads to hemodynamic disorders by inhibiting left ventricular filling. Depending on the patient’s status, percutaneous intervention or surgery is recommended for the treatment of moderate–severe MS patients (mitral valve area
