ABSTRACT

Objective:
As a part of point-of-care ultrasound (POCUS), the rapid assessment of cardiac systolic function using tricuspid annular plane systolic excursion (TAPSE) and mitral annular plane systolic excursion (MAPSE) are thought to be valuable tools during a cardiac emergency. This article is an untact pilot experiment before the clinical application of these procedures in an emergency room.
Method:
Totally, 206 video samples from YouTube concerning echocardiograms of a normal heart, ischemic heart disease, congestive heart failure, cardiomyopathy, pulmonary hypertension, and pulmonary embolism were extracted and analyzed with free programs opened in internet services.
Results:
The values of MAPSE, TAPSE, and TAPSE+MAPSE ranged between 13.3±2.3 mm, 23±2.8 mm, and 36±4.5 mm, respectively, in the normal echocardiogram versus 7.8±2.5 mm, 16.5±5.0 mm, and 24.2±6.4 mm, respectively, in an abnormal echocardiogram (P<0.05). Positive correlations were obtained between MAPSE and TAPSE, MAPSE and TAPSE+MAPSE, and TAPSE and TAPSE+MAPSE (R²=0.346, R²=0.687, and R²=0.871, respectively). MAPSE ≤ 7.7 mm, TAPSE ≤18.5 mm, and TAPSE+MAPSE ≤27.7 mm show 100% sensitivity, and the specificities for an abnormal echocardiogram at these values are 51.8%, 63.3%, and 71.7%, respectively. At TAPSE ≤18.5 mm and TAPSE/(TAPSE+MAPSE) ≤0.61, the sensitivity of pulmonary hypertension containing a pulmonary embolism is 81.2%, and the specificity is 81%. It is presumed that the lower these values, the higher the emergency.
Conclusion:
In a cardiac emergency, differentiating left or right systolic heart failure is probably useful by checking not only MAPSE or TAPSE using POCUS, but also determining the ratios MAPSE/(MAPSE+TAPSE) or TAPSE/(MAPSE+TAPSE). However, further retrospective or prospective studies in an emergency room are required for a specific disease diagnosis.
