Feasibility Trial Evaluating Efficacy and Safety of Solitaire™ Thrombus Retrieval Device in the Management of Refractory Thrombus in Patients With Acute Coronary Syndrome (Solitaire)
Studienübersicht

Intervention / Behandlung
Detaillierte Beschreibung
We hypothesize that Solitaire device could be effectively and safely used as an adjunctive interventional technique in ACS patients found to have refractory thrombus during PCI.
- Primary Objectives To evaluate intra-procedure efficacy of using Solitaire in ACS patients with refractory thrombus.
- Secondary Objectives To evaluate clinical efficacy of using Solitaire in ACS patients with refractory thrombus, up to one year post-procedure.
To evaluate safety of using Solitaire in ACS patients with refractory thrombus.
The target enrolment is 51 patients diagnosed with STEMI, NSTEMI or UA and found to have refractory thrombus during PCI. Eligible patients will be identified at the ED or Inpatient ward of the 5 participating hospitals. The projected enrolment period is for two years and follow up for one year. A screening log will be maintained at each site to keep record of patients who were eligible for the study but not enrolled, to establish any selection bias.

After consent has been obtained, interventional cardiologist selects the proper solitaire device size per device-specific instructions for use.
Adjunctive intervention with Solitaire will be done with a maximum of 2 device deployments.
Do not perform more than three recovery attempts in the same vessel using the devices (Maximum of 2 attempts per device per subject).
Do not reposition each device more than two times.
TIMI flow, thrombus grade and myocardial blush grade will be assessed immediately upon completion of procedure.
If recanalization is deemed inadequate by the interventional cardiologist, rescue treatment will follow as per current clinical practice.
All other procedures followed will be as clinically indicated.
