Flow of Patients Through Each Stage of the Trial One hundred fifty nine patients with acute pulmonary embolism (PE) were screened for eligibility across 22 study sites. One hundred fifty patients were eligible for enrollment. One patient died before the ultrasound-facilitated, catheter-directed, low-dose fibrinolytic procedure could be completed. One hundred fifteen patients had a within-window contrast-enhanced chest computed tomogram (CT) for measurement of change in right ventricular-to-left ventricular (RV/LV) diameter ratio. Ninety eight patients had a within-window echocardiogram to estimate 48-h pulmonary artery (PA) systolic pressure. t-PA = tissue-plasminogen activator.
