Overview
Brief Summary
Prospective, multicenter, open label, randomized controlled clinical trial to compare the effects of an early catheter-directed treatment plus conventional care with conventional care in patients with high-risk pulmonary embolism
Investigators
Eligibility Criteria
Inclusion Criteria
- •Pulmonary embolism as confirmed by CT angiogram with high mortality risk as defined by ESC guidelines:
- •a) One of the following: i. Cardiac arrest or ii. obstructive shock (systolic BP \<90 mmHg or vasopressors required to achieve a BP ≥90 mmHg despite an adequate filling status), in combination with end-organ hypoperfusion (cold, clammy skin, oliguria or serum lactate ≥2 mmol/L) and b) Signs of right-ventricular dysfunction on transthoracic echocardiogram or CT scan
- •Age ≥18 years
Exclusion Criteria
- •Contraindications for catheter-based treatment
- •Contraindications to systemic fibrinolytic treatment or anticoagulation\*
- •Active, potentially life-threatening bleeding
- •Surgery within 24h before screening
- •Cranial or spinal surgery within 14d before screening
- •Stroke within 14d before screening
- •Intracranial tumor
- •Any condition not listed here but estimated as clinically relevant as judged by the treating investigator
- •Patients with contraindications to systemic fibrinolysis or anticoagulation can be enrolled in a third study arm (registry) and undergo catheter-directed therapy.
Arms & Interventions
conventional care
Patients in the conventional care group will receive guideline directed therapy including reperfusion treatment. If no clinically relevant hemodynamic improvement occurs, catheter-interventional treatment may be used as stated in the current ESC-guidelines
Intervention: Conventional care
Early Catheter-Interventional Treatment + conventional care
Patients in this group will undergo a catheter-interventional treatment within 60 min. after randomization. Fibrinolytic treatment will be prepared parallel to interventional treatment preparations to avoid any delay in its administration, if clinically necessary. Catheter-interventional treatment may include any certified devices for the treatment of PE including aspiration thrombectomy, local fibrinolytic therapy, local ultrasound treatment as assistance to local fibrinolysis or any combination of these. Transfemoral venous access routes will be used for any catheter-directed treatment using sheath-sizes as recommended in the IFUs by the respective manufacturers. Sheaths will be withdrawn immediately after catheter-based thrombectomy or after completion of catheter-directed local fibrinolysis, typically 5 to 10 hours after initiation. The choice of the catheter types and sizes will be left to the treating interventionalists' discretion.
