What echocardiographic findings differentiate acute pulmonary embolism and chronic pulmonary hypertension?
2023, American Journal of Emergency MedicineWhat are the echocardiographic findings of acute right ventricular strain that suggest pulmonary embolism?
2021, Anaesthesia Critical Care and Pain MedicineCitation Excerpt :However, when pulmonary hypertension is present, the flow will demonstrate a transient decrease in velocity during the pulmonary arterial systolic flow cycle, resulting in the appearance of biphasic flow (Fig. 9b). This is referred to as pulmonary artery mid-systolic notching [88–93]. This finding has been hypothesized to be caused by impedance of flow against elevated PAP [92,94,95], in that the reflected pressure waves return prematurely due to their faster propagation in the non-compliant pulmonary vessels [96].

2018, Journal of the American Society of EchocardiographyCitation Excerpt :The flowchart of the screening process is presented in Figure 2. Eventually, 21 articles published between 1983 and 2016, representing a total of 1,280 patients, were included in our systematic review.4,13,16-33 The main characteristics of the trials included in the systematic review and retained for meta-analysis are summarized in Table 1 and Supplemental Table 1 (available at www.onlinejase.com).
