Acute Effect of Treatment of Mitral Stenosis on Left Atrium Function

AIM: Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR). METHODS: Patients with severe symptomatic MS, who were referred to our...

Sumario:AIM: Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR). METHODS: Patients with severe symptomatic MS, who were referred to our echocardiographic laboratory for a diagnostic examination before cardiac surgery or PTMC from October of 2014 to October of 2015, were included in the study. RESULT: The peak systolic global LA strain improved post-PTMC (P < 0.001) and post-MVR (P = 0.012). This difference was statistically highly significant. CONCLUSION: PALS is impaired in patients with severe symptomatic MS and improved acutely after treatment and may be a good indicator of LA function and may predict the right time for intervention on mitral valve.
