The clinical significance of pulmonary embolism (PE) limited to the subsegmental pulmonary arteries, so called isolated subsegmental pulmonary embolism (SSPE), remains controversial. Whether isolated SSPE represents "true" PE, a clinically more benign form of PE, a physiologic lung clearing process, or a false positive result (artifact) is currently unclear and hence, whether patients with isolated SSPE benefit from anticoagulant treatment is uncertain. Despite growing evidence from observational studies that withholding anticoagulation may be a safe option in selected patients with isolated SSPE (i.e., those without concomitant deep vein thrombosis, cancer, etc.), most patients with isolated SSPE receive anticoagulant treatment, which is associated with an increased risk of bleeding. The overall objective of the randomized controlled SAFE-SSPE trial is to evaluate the efficacy and safety of clinical surveillance without anticoagulation compared to anticoagulation treatment in low-risk patients with isolated SSPE.

Pulmonary Embolism

There are many available treatments for pulmonary embolism (PE), but the best treatment for this condition is not known. The HI-PEITHO study will compare two treatment options that are both available on the market for the treatment of PE. Patients will be randomized 1:1 to receive either blood thinners (anticoagulation) or blood thinners (anticoagulation) in combination with a device called the EkoSonicTM Endovascular device to dissolve blood clots. Patients will be followed for 12 months after randomization and have assessments while in the hospital as well as at 7 days, 30 days, 6 months and 12 months after randomization. The study will try to find out if one of these treatments is better than the other at reducing the risk of death and other serious problems.

Catheter-directed Thrombolysis in Intermediate-high Risk Acute Pulmonary Embolism

Pulmonary Embolism

Background: Intermediate-high risk acute pulmonary embolism (PE) remains associated with substantial mortality despite standard anticoagulation therapy. Previous efforts to decrease mortality in these patients via administration of systemic thrombolysis have failed due to an increased rate of major bleeding complications. Catheter-directed thrombolysis (CDT) has already shown some promising results in terms of efficacy and safety, including the results of our randomized pilot study. However, large randomized trials with clinical endpoints comparing catheter-directed local thrombolysis versus standard anticoagulation therapy are still lacking, thus the treatment of intermediate-high risk acute PE patients has not changed for decades. Hypothesis: Catheter-directed local thrombolysis is superior to standard anticoagulation therapy in the treatment of intermediate-high risk acute pulmonary embolism, with no additional safety concerns. Statistical considerations: Estimated incidence of the primary endpoint of 1.5% in the CDT group and 6.0% in the standard anticoagulation group, 80% power for each arm with a 2-sided alpha of 0.05. Five hundred fifty-eight should provide the requisite number of events. Statistical Analysis - Intention to Treat. Methods and Results: A Multicentre, Randomized Trial of Catheter-directed thrombolysis in intermediate-high risk acute pulmonary embolism (PRAGUE-26) is a noncommercial, multicentre, randomized, controlled parallel-group comparison trial. The trial plans to include 558 patients with intermediate-high risk acute PE. Patients will be randomized in a 1:1 ratio to CDT or to standard anticoagulation therapy. The primary outcome of the study is a clinical composite of all-cause mortality, PE recurrence or cardiorespiratory decompensation, within 7 days of randomization. Secondary objectives cover all bleeding complications, functional and patient-reported outcomes over a follow-up period of 24 months and cost-effectiveness analysis.

Catheter-interventional Treatment of Pulmonary Embolism

Pulmonary Embolism

Recent evidence supports the use of catheter-interventional techniques for the treatment of intermediate-high-risk pulmonary embolism. While there is evidence supporting the use of catheter-thrombectomy and alternatively local fibrinolysis, less is known on the combination of both approaches. The investigators aim to assess the effects of a combined interventional local fibrinolysis and catheter-thrombectomy and to compare them with conventional treatment in a cohort of patients with intermediate-high-risk pulmonary embolism.
