Speckle Tracking Echocardiography Analysis of Left Ventricular Myocardium After Percutaneous Intramyocardial Septal Radiofrequency Ablation for Hypertrophic Obstructive Cardiomyopathy

Hypertrophic Obstructive Cardiomyopathy Clinical Trial

Official title:
Left Ventricular Systolic Function After Percutaneous Intramyocardial Septal Radiofrequency Ablation for Hypertrophic Obstructive Cardiomyopathy: a Study Focused on Speckle Tracking Echocardiography

Clinical Trial Summary

Objective to investigate the left ventricular (LV) systolic function by speckle tracking echocardiography before and after percutaneous intramyocardial septal radiofrequency ablation for hypertrophic obstructive cardiomyopathy (HOCM). Percutaneous intramyocardial septal radiofrequency ablation (named Liwen Procedure) is a safe and effective treatment approach for HOCM and results in sustained improvement in exercise capacity and persistent in reducing left ventricle outflow tract (LVOT) gradient. However, the systolic function of the myocardial after Liwen procedure in HOCM patients is not well exploration and research. Strain evaluation using speckle tracking echocardiography is an excellent tool for assessing regional and global LV functions. In this study, the investigators aimed to characterize regional and global strain using speckle tracking echocardiography to assess LV radial, circumferential and longitudinal systolic myocardial function in patients with HOCM before and after Liwen procedure.
