Percutaneous Transvenous Mitral Commissurotomy (PTMC) is the first line treatment for rheumatic mitral stenosis (MS). We sought to evaluate (1) changes in 2-dimensional (2D) echocardiographic and strain values and (2) differences in these values for patients in atrial fibrillation (AF) and sinus rhythm (SR) pre, immediately and 6 months post PTMC. Retrospective study of 136 patients who underwent PTMC between 2011 and 2021. We analyzed their 2D echocardiogram, Global Longitudinal Strain (GLS), Left Atrial Reservoir Strain (LAr-S) and Right Ventricle Free Wall Strain (RVFW-S) pre, immediately and 6 months post PTMC. At 6 months, mitral valve area increases from 0.94 ± 0.23 cm2 to 1.50 ± 0.42 cm2. Ejection fraction (EF) did not change post PTMC (pre; 55.56 ± 6.62%, immediate; 56.68 ± 7.83%, 6 months; 56.28 ± 7.00%, p = 0.218). Even though EF is preserved, GLS is lower pre-procedure; - 11.52 ± 3.74% with significant improvement at 6 months; - 15.16 ± 4.28% (p

BACKGROUND: Athletes have changes that can mimic pathological cardiomyopathy.
METHODS: Echocardiographic study of 50 male, female athletes (MA, FA) and non-athletes (MNA, FNA) age 18 to 30 years. These athletes participate in sports with predominantly endurance component. All participants exhibit no known medical illnesses or symptoms.
RESULTS: MA have thicker wall (IVSd) than MNA. No MA have IVSd > 1.2 cm and no FA have IVSd > 1.0 cm. Left ventricle internal dimension (LVIDd), left ventricle end diastolic volume index (LVEDVi) is bigger in athletes. None have LVIDd > 5.8 cm. Right ventricle fractional area change (FAC) is lower in athletes. (MA vs MNA, p = 0.013, FA vs FNA, p = 0.025). Athletes have higher septal and lateral e' (Septal e'; MA 13.57 ± 2.66 cm/s vs MNA 11.46 ± 2.93 cm/s, p 1.2 cm and/or LVIDd > 5.8 cm. There is no difference in GLS, RVFWS and GCS but athletes have smaller LArS and LAbS.
