Abstract
Objective: Left ventricular (LV) systolic functions are generally depressed in Mitral Stenosis (MS). Recovery of LV systolic functions demonstrated with 2D echocardiography in some patients by mitral balloon valvuloplasty (MBV). Systolic mitral annular velocity (S') by Tissue Doppler Imaging (TDI) predicts LV systolic function. We aimed to evaluate early effects of MBV on LV systolic function by TDI. Methods: Forty-eight consecutive patients included to the study (39 female, 36±10 years). A full transthoracic echocardiographic study (TTE) including left ventricular ejection fraction assessment by teicholz method and mitral annular color TDI assessment was performed 24 hours before and after MBV in all patients. MBV performed by noue technique under guidance of TTE. Analysis of mitral lateral annular S' wave velocity was performed immediately after echocardiographic examination. Results: MBV performed successfully in 43 patients (Group A), and severe mitral regurgitation developed in 5 patients (Group B). Mitral valve area, and S' wave velocity increased, mean and maximum mitral gradient, and left atrial diameter, and systolic pulmonary artery pressure (PAP) were reduced significantly by MBV in group A patients (p
