Tricuspid Annular Plane Systolic Excursion (TAPSE) Measurement by Emergency Medicine Residents in Patients Suspected of Pulmonary Emboli

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 =
