Mechanical Thrombectomy via Cleaner ProCleaner Pro Thrombectomy SystemParticipants will receive catheter-directed therapy via mechanical aspiration thrombectomy for the treatment of pulmonary embolism (PE) using the Cleaner Pro Thrombectomy System.
Primary Outcome Measures
NameTimeMethod
Change in Right Ventricle (RV)/Left Ventricle (LV) RatioAt 48 hours post-procedure

Change in RV/LV ratio between baseline and 48 hours post procedure assessed by CTA.

Rate of Major Adverse Events (MAEs)At 48 hours post-procedure

Rate of MAEs within the first 48 hours after the index procedure, defined as:

Device-related death Major bleeding, and Device-related Serious Adverse Events which includes clinical deterioration, pulmonary vascular injury, and cardiac injury.

Secondary Outcome Measures
NameTimeMethod
Rate of device-related SAEs and all-cause mortalityWithin 30 days of procedure

Rate of device-related serious adverse events (SAEs) and death for any cause within 30 days post-procedure.

Use of thrombolyticsWithin 48 hours of the procedure

Use of thrombolytics within 48 hours of the procedure.

Rate of device-related complications and device-related deathWithin 48 hours of the procedure

Rate of device-related complications including major bleeding, clinical deterioration, pulmonary vascular injury, and cardiac injury, and device-related death within 48 hours of the index procedure.

Rate of Symptomatic PE RecurrenceWithin 30 days of the procedure

Rate of Symptomatic PE recurrence within 30 days.

Volume of blood aspiratedAt index procedure

The amount of blood aspirated during the procedure.

Quality of Life assessed via PEmb-QoLAt 30 days post-procedure

Self-assessment of PE-related complaints and daily living limitations (including work and social). The PEmb-QoL measures 6 dimensions, with higher scores being worse.

Quality of Life assessed via EQ-5D-5LAt 30 days post-procedure

Self-assessment of activities for daily living. The EQ-5D-5L measures 5 dimensions, with higher scores being worse.

Change in Modified Miller IndexAt 48 hours post-procedure

Change in Modified Miller Index between baseline and 48 hours post-procedure assessed by CTA. This index score quantifies arterial obstruction in pulmonary embolism. The higher the score, the more perfusion is reduced.
