Pressure-controlled Intermittent Coronary Sinus Occlusion (PiCSO) in Acute Myocardial Infraction (PiCSO-AMI-I)
Sponsor: Miracor Medical SA
Interventional Clinical Trial
Pressure controlled intermittent Coronary Sinus Occlusion (PICSO) V Conventional Therapy ie percutaneous coronary intervention (PCI).
The objective of this study is to assess efficacy and safety of Pressure-controlled intermittent Coronary Sinus Occlusion (PiCSO) therapy started post flow restoration but prior to stenting during percutaneous coronary intervention (PCI) compared to standard PCI in the setting of acute ST-segment elevation anterior myocardial infarction (STEMI).
This is a prospective, multicenter, randomized (1:1), controlled, study. Patients with an ST-segment elevated anterior infarct eligible for PCI will be invited to participate in the PiCSO-AMI-I study. After having given verbal assent, baseline assessments will be performed. PCI of the culprit vessel should be performed per standard practices. After blood flow restoration, the subjects meeting all inclusion and none exclusion criterial 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 (at minimum 30 minutes) whereas the treatment should be continued during and post stent insertion, but should not exceed a maximum duration of 90 minutes. 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 seen for a FU visit at 5 days, 30 days, 6 months, 1 year, 2 year and 3 years post index procedure. 5 days and 6 months post index the patient will get a CMR scan. At every FU visit safety data and health status will be documented and quality of life questionnaire will be completed.
