STEMI - ST Elevation Myocardial Infarction Clinical Trial
Official title:
A Randomized, Controlled, Pilot Study to Evaluate Safety and Feasibility of Pressure-controlled Intermittent Coronary Sinus Occlusion (PiCSO) Therapy in Patients With ST Elevation Inferior Wall Myocardial Infarction Presenting With TIMI 0 or 1 and Symptom Duration ≤ 12 Hours Treated Adjunct to Percutaneous Coronary Intervention (PCI) Compared to Standard PCI.
The objective of this study is to assess safety and feasibility of Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) therapy in patients with extensive ST elevation inferior wall myocardial infarction presenting with TIMI 0 or 1 and symptom duration ≤ 12 hours undergoing percutaneous coronary intervention (PCI) compared to standard PCI.
This is a multicenter, randomized (2 PiCSO :1 Control), controlled, pilot study to evaluate safety and feasibility of Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) therapy in patients with extensive ST elevation inferior wall myocardial infarction presenting with TIMI 0 or 1 and symptom duration ≤ 12 hours treated adjunct to percutaneous coronary intervention (PCI) compared to standard PCI. Patients with an ST-segment elevated inferior infarct eligible for PCI will be invited to participate in the PiCSO-AMI-V Inferior STEMI study. After consent as per approved ethics committee requirements, baseline assessments will be performed. PCI of the culprit vessel should be performed per standard practices. After TIMI flow restoration, the subjects meeting all eligibility criteria will be enrolled into the study and randomized either to PiCSO Group or Control Group. If the subject is randomized to PiCSO Group, the coronary sinus (CS) will be cannulated through the femoral vein and the PiCSO Impulse Catheter will be placed in the CS. In the event the PiCSO Impulse Catheter cannot be placed in the CS within 30 minutes, the physician should proceed with the regular PCI and the PiCSO treatment will be considered a failure. Once PiCSO Impulse Catheter is placed into CS, PiCSO treatment is started followed by stenting. The physician shall target a PiCSO treatment of 45 minutes whereas the treatment should be continued during and post stent insertion. At the end of the PiCSO treatment, the PiCSO Impulse Console is stopped and the PiCSO Impulse Catheter is removed. The patient is seen for a FU visit at 12-36 hours, 30 days, 6 months and 1 year post index procedure. 12-36 hours and 6 months post index the patient will get a echocardiogram. At every FU visit safety data and health status will be documented. ;
