Clinical value of 2D speckle tracking imaging in evaluating the effect of percutaneous intramyocardial septal radiofrequency ablation in patients with hypertrophic obstructive cardiomyopathy

Purpose To explore the short‐term changes after percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) in patients with hypertrophic obstructive cardiomyopathy (HOCM), using quantitative analysis of two‐dimensional speckle tracking imaging (2D‐STI). Methods This prospective self‐controlled study included 30 HOCM patients treated with PIMSRA. The study for each patient spanned over at least 1 year. Interventricular septal thickness...
