Abstract

Objectives: We aimed to evaluate the ability of emergency medicine (EM) residents to measure tricuspid annular plane systolic excursion (TAPSE) by M-Mode ultrasound. Methods: Four EM residents with prior focused cardiac ultrasound (FOCUS) experience participated in 10 hours of hands-on training and then performed TAPSE measurements in adult patients at high risk of having pulmonary emboli (PE) between December 2020 and April 2021. Patients underwent bedside echocardiography by cardiology residents, and a CT pulmonary angiogram (CTPA) was performed to confirm the diagnosis. The agreement between EM and cardiology residents was assessed by intraclass correlation coefficient (ICC). Results: Sixty-six patients were included (mean age = 58.7 ± 16.7 years), of which 28 patients (42.8%) had positive CTPA. The mean TAPSE, measured by EM residents was 16.36 ± 1.59 mm in the PE positive group and 21.68 ± 2.87 mm in the PE negative group (P-value = <.0001). The mean ± SD TAPSE, measured by cardiology residents, was 17.7 ± 1.98 mm in the PE group and 22.5 ± 3.6 mm in the PE negative group (P-value = <.0001). There was significant agreement between EM and cardiology residents in terms of measuring TAPSE (ICC = 0.91, 95% confidence interval [CI] = 0.80–0.95). The receiver operating characteristic (ROC) curves of TAPSE for diagnosing PE revealed that TAPSE, measured by EM residents, had a high level of accuracy (area under the ROC curve [AUC] = 0.93, 95% CI, 0.878–0.99). Conclusions: EM residents can perform M-Mode TAPSE measurement in suspected PE cases after 10 hours of hands-on training. TAPSE measurement should be added to routine FOCUS protocols, especially when there is suspicion of PE. © 2021 American Institute of Ultrasound in Medicine.
