Official title

USAT-CDT Trial: Standard vs Ultrasound-assisted Catheter Thrombolysis for Submassive Pulmonary Embolism

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The study is an investigator-initiated trial comparing two different catheters (standard versus ultrasound assisted) for the treatment of acute high risk pulmonary embolism (blood clots in lung arteries with evidence or heart strain). Patients already planned for the procedure will be randomized to standard catheter-directed thrombolysis (CDT) or to ultrasound-assisted catheter thrombolysis (USAT). Both catheters are currently used routinely in practice for the treatment of pulmonary embolism, but it is not known if USAT is superior to standard CDT, the former being much more expensive and more commonly used. The purpose of the study is to learn about which catheter-directed therapy is more suitable for patients with pulmonary embolism (PE), who are candidates for both standard catheter directed therapy (CDT), and ultrasound-assisted catheter directed therapy (USAT), and to provide information regarding the cost effectiveness of the two different types of treatment. A total of 80 patients are planned to be recruited. All medication administration, procedures or in-hospital tests will be performed as routine clinical practice. The study will compare short term and long term outcomes: resolution of blood clots on CT scan, right ventricular size improvement, quality of life and symptoms at 3 and 12 months, and cost effectiveness.
