To investigate the potential of Mitral Annular Plane Systolic Excursion (MAPSE) as a bedside surrogate for monitoring ventriculoarterial (VA) coupling in critically ill patients.
Approach:
Study Review: The article reviews findings from Valenzuela et al. regarding the unpredictability of VA coupling responses in critically ill patients and the inadequacy of conventional assessment methods.
Correlation Analysis: Exploratory analysis of correlations between MAPSE and non-invasive VA coupling estimates using both manual and AI-based approaches.
Key Findings:
VA coupling responses correlate weakly with changes in cardiac output, stroke volume, and left ventricular ejection fraction, as reported by Valenzuela et al.
MAPSE has been validated and is recognized in critical care guidelines according to Cavefors et al.
Cavefors et al. reported that MAPSE showed strong prognostic value in critically ill patients, potentially exceeding that of left ventricular ejection fraction and global longitudinal strain.
Correlations between MAPSE and VA coupling estimates were found (rho = -0.73 for manual calipers, rho = -0.61 for AutoMAPSE) in exploratory analyses.
Limitations:
Current findings require confirmation through additional analyses as noted in the source material.
Clinical implementation of MAPSE needs to clarify how it can direct and track therapeutic effects, as highlighted by Cavefors et al.
Conclusion:
Further exploratory analyses are needed to assess the concordance of MAPSE changes with VA coupling and other hemodynamic parameters, as suggested by Valenzuela et al.
An aortic dissection occurs when a tear develops in the inner layer of the aorta, the body’s largest artery. Blood can force its way between layers of the vessel wall, compromising circulation to vital organs or causing catastrophic internal bleeding.
