Marcin Kurzyna: New NEJM Trial Evaluates Catheter-Directed Thrombolysis in PE

Marcin Kurzyna, Chairman-Elect of Working Group on Pulmonary Circulation and Right Ventricular Function at European Society of Cardiology, shared a post on LinkedIn about a recent article by Josef Kroupa et al, published in The New England Journal of Medicine, adding:

“The next landmark trial in the field of interventional treatment of pulmonary embolism is coming from Czechia!

Catheter-directed thrombolysis (without ultrasound) versus anticoagulation alone in intermediate-high-risk PE with some additional ‘red flags’ in a prospective, multicenter, open-label trial.

Mortality/morbidity combined endpoint driven by clinical deterioration, without differences in mortality, but 4 deaths (1.4 percent) in the AC group versus 1 in the CDT group (0.36 percent, p=NS).

Two intracranial bleedings in CDT group versus none in AC (p=NS), but without increase of major bleeding in the CDT cohort.

No evidence for a more extensive reduction in the RV/LV ratio after 48 h in the CDT group.

Big kudos and congratulations to Josef Kroupa and the whole group!

Presented at ESC Congress and published simultaneously in NEJM.”
