Key result
Transthoracic echocardiography detected impaired left atrial deformation parameters in patients with moderate to severe mitral stenosis, with 83.5% showing increased maximal left atrial volume.

LA deformation assessment may aid mitral stenosis evaluation; leaves open its prognostic role and impact on management.
Objectives: to assess the left atrial deformation parameters in patients with moderate to severe mitral stenosis by transthoracic echocardiography. Methodology: this study was conducted on 30 patients with moderate to severe mitral stenosis presented to Cardiovascular Department in Minia University Hospital from 1/11/2018 to 30/10/2019, Left atrial (LA) volume parameters (maximum, minimum and pre atrial contraction) were measured. Results: 25 patients (83.5%) in this study had increased maximal left atrial volume (>34 ml indexed to body surface area) and 5 patients (16.7%) had normal maximal volume (<34ml/BSA) with median LA MAX volume (61.5 ml/BSA) and for minimal left atrial volume 26 patients (86.7%) had increased minimal left atrial volume (>14 ml/BSA) and 4 patients (13.3%) had normal minimal LA volume (<14 ml/BSA). Conclusion: left atrial deformation parameters were impaired in patients with moderate to severe mitral stenosis detected by transthoracic echocardiography.

Sayed et al. (2020) conducted an observational in Moderate to severe mitral stenosis (n=30). Transthoracic echocardiography was evaluated on Left atrial volume parameters (maximum, minimum and pre atrial contraction). Transthoracic echocardiography detected impaired left atrial deformation parameters in patients with moderate to severe mitral stenosis, with 83.5% showing increased maximal left atrial volume.
