Conventional echocardiography and RV function by TDI\u2010derived longitudinal strain and strain rate were assessed prior and 24\u00a0hours post PTMC and compared with 40 healthy age\u2010matched controls.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eighty subjects (mean age 31\u00a0+\u00a010\u00a0years, 70% females) were included. Patients with MS had significantly lower RV strain of basal and mid\u2010free wall, tricuspid annular plane systolic excursion (TAPSE), and RV fractional area change (FAC) as compared to controls. There was a significant increase in pre\u2010 and post\u2010PTMC in TAPSE (19.5\u00a0\u00b1\u00a02.7\u00a0mm vs 21.4\u00a0\u00b1\u00a03.3\u00a0mm; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), RV basal free wall longitudinal strain (\u221224.4\u00a0+\u00a06.1% vs \u221227.7\u00a0+\u00a05.8%; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), and right ventricle mid\u2010free wall longitudinal strain (\u221225.6\u00a0+\u00a05.5% vs \u221228.6\u00a0+\u00a05.1%; <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001), respectively.
