Pulmonary vascular disease & thromboembolism

Randomized controlled trial of mechanical thrombectomy vs catheter-directed thrombolysis for acute hemodynamically stable pulmonary embolism: Rationale and design of the PEERLESS study

Am Heart JPublished Randomised controlled trial

Study context

Population
Hemodynamically stable pulmonary embolism (PE) patients with right ventricular (RV) dysfunction and additional clinical risk factorsplanned
Participants
550 patients
Planned comparison
Large-bore mechanical thrombectomy vs catheter-directed thrombolysis
Primary endpoint
Hierarchical win ratio composite:
  1. All-cause mortality
  2. Intracranial hemorrhage
  3. Major bleeding
  4. Clinical deterioration and/or escalation to bailout
  5. ICU admission
  6. Length of stay
Follow-up
Hospital discharge or 7 days post procedure, whichever is sooner
