Tricuspid regurgitation was assessed using two-dimensional (2D) echocardiography and classified into grades 1–4 based on vena contracta and proximal isovelocity surface area measurements.

This review discusses the implications of LA strain in patients with severe MS, its prognostic value, and potential therapeutic implications. A comprehensive narrative review was executed to report current findings in cardiovascular research.

Inclusion criteria encompassed peer-reviewed articles published in English at any time till March 2025. The results indicate that Left atrial strain analysis offers a promising tool for the evaluation of LA mechanics in individuals with severe MS.

Although considered a rare disorder, its prevalence has increased over the last decades due to increased detection, as a consequence of enhancement in imaging technologies, and population aging [&lt;span&gt;1, 2&lt;/span&gt;]. Specifically, in the US population, there was an increase in the prevalence rate (8 to 17 per 100 000 person-years) and incidence rate (18 to 55 per 100 000 person-years) from 2000 to 2012 [&lt;span&gt;3&lt;/span&gt;]. As CA is frequently undetected and portends a poor prognosis with a high mortality rate, early detection is of paramount importance in order to introduce therapies that can improve survival and quality of life [&lt;span&gt;4&lt;/span&gt;]. Unfortunately, CA is still overlooked among patients with heart failure with preserved ejection fraction.&lt;/p&gt;&lt;p&gt;Echocardiography carries a Class 1B recommendation for diagnosing CA and is the typical first cardiac imaging modality for these patients [&lt;span&gt;5&lt;/span&gt;]. In order to increase CA suspicion and diagnosis, several red flags on echocardiography were described by the The American Society of Echocardiography: increased left ventricular (LV) and right ventricular (RV) wall thickening, biatrial enlargement, increased LV wall thickness with low-voltage criteria on associated electrocardiogram, diastolic dysfunction (≥grade II) with elevated LV filling pressures, severely reduced mitral annular tissue Doppler velocities, reduced global longitudinal strain (GLS) with apical sparing, low-flow low-gradient aortic stenosis, pericardial effusion, increased atrial septal thickness, diffuse valve thickening, and preserved ejection fraction with low stroke volume index [&lt;span&gt;6&lt;/span&gt;]. However, the overlapping symptoms with other cardiac pathologies common in elderly population often result in diagnostic delays [&lt;span&gt;2&lt;/span&gt;]. Therefore, new tools to facilitate CA suspicion during echocardiography are of great importance. The paper by Lin et al.
