Study summary

A prospective observational study to evaluate the safety and effectiveness data of catheter-directed therapy (CDT) including percutaneous mechanical thrombectomy (PMT) for treatment of acute pulmonary embolism (PE)

Read the detailed description

The primary objective of this study is to capture high quality patient safety and effectiveness data on CDT for acute PE. The goal will be achieved by capturing a concise set of immediate and short-term functional and clinical outcome data for PE patients undergoing CDT.

Secondary study objectives include the following:

- To assess and benchmark clinical practice patterns (patient selection, optimal technique, use of procedure worldwide)

These objectives will be achieved through the capture of selected process data for patients included in the registry. Data collected in this study may also be used to develop and refine standards of care for use of CDT for PE and to facilitate the design of randomized clinical trials

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jan 2010 to primary completion in Jan 2020, 120 months.

Of 122 non-industry observational studies under Pulmonary Embolism, half reached primary completion within 53 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 120. This study's 120 months is above that.

Counting every sponsor, half of 145 studies reached it within 48 months; a quarter within 23 and three quarters within 105.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 8, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
