“…Although many reports have evaluated AcT/RVET and PAP, those studies did not assess the process of recovery of RV morphology and function after treatment of APTE. [16][17][18][19][20] In the present study, PAP could not be evaluated by AcT/ RVET in patients with APTE, but our results showed that AcT/RVET could be a clinically useful index for evaluating the residual thrombus in patients with APTE after treatment following normalization of PAP. Such assessment is not only suitable for hospitalized patients, but could be also used in the outpatient clinic to assess the effect of anticoagulant therapy.…”

“…[16][17][18][19][20][21] Although several possible mechanisms of these phenomena have been proposed, the major underlying mechanism has not yet been established. The proposed mechanisms include the waveform reflecting the ejection flow in peripheral pulmonary vessel in response to increased pressure, 16 turbulent flow caused by the presence of a dilated pulmonary artery (PA), 21 increased afterload because of reduced compliance of the PA, 18,19 and involvement of the RV ejection fraction. 20 In the present study, we found a negative correlation between mPAP, TPR and AcT/RVET during the acute phase of APTE.…”

“…Back in the 1980s, it was shown that in adult patients with PAAT values <100 ms, there is a linear inverse relationship between the PAAT and the mean PAP (mPAP). [1][2][3][4][5] However, an increased heart rate (HR) is suspected to shorten the PAAT. In adults, the PAAT was shown to correlate strongly with mPAP 1 and can be measured in adults and in children.…”
