What is the clinical evidence from this study?

Study design: Observational. Population: Patients undergoing cardiac surgery (n=49). Intervention: Single-wall autoMAPSE vs. Manual global MAPSE. Primary outcome: Trending ability (concordance rate) of single-wall autoMAPSE compared to manual global MAPSE.

What question did this study set out to answer?

Automatic monitoring of single-wall MAPSE by transesophageal echocardiography for tracking global left ventricular function irrespective of regional hypokinesia: a secondary analysis

Key Result

Single-wall autoMAPSE tracked changes in global left ventricular function with a 91% concordance rate compared to manual global MAPSE, irrespective of regional wall motion abnormalities.

Key Points

This analysis aims to evaluate the effectiveness of single-wall autoMAPSE in monitoring global left ventricular function regardless of regional wall motion abnormalities.
Conducted a secondary analysis of existing echocardiographic data.
Utilized transesophageal echocardiography for assessment.
Focused on tracking global left ventricular function with single-wall autoMAPSE.
Analyzed cases with and without regional wall motion abnormalities.
Single-wall autoMAPSE successfully tracked changes in global left ventricular function in 9 out of 10 cases.
Demonstrated effectiveness irrespective of presence of regional wall motion abnormalities.

Structured PICO

Does automatic monitoring of single-wall MAPSE by transesophageal echocardiography accurately track global left ventricular function irrespective of regional hypokinesia?

Population

Cases evaluated for global left ventricular function and regional wall motion abnormalities (RWMA)

Intervention

Automatic monitoring of single-wall MAPSE (mitral annular plane systolic excursion) by transesophageal echocardiography (autoMAPSE)

Outcome

Tracking changes in global LV functionsurrogate

Single-wall autoMAPSE by transesophageal echocardiography appears to be a reliable tool for tracking global LV function even in the presence of regional wall motion abnormalities.

Limitations

Relatively small sample size
Septal wall autoMAPSE did not show adequate trending ability
No comparison of changes in MAPSE versus those of global longitudinal strain
Subjective visual analysis of regional wall motion abnormalities was performed by echocardiographic researchers rather than expert cardiologists

Abstract

In this secondary analysis, single-wall autoMAPSE tracked changes in global LV function in 9 out of 10 cases, irrespective of RWMA.
