Semi Occlusion of the Coronary Sinus as an Adjunct to PCI in STEMI Patients, FIH Clinical Study
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
The Booster Balloon Catheter, while inflated, causes partial occlusion of CS blood flow and thus increases the coronary sinus venous pressure. It is hypothesized that the utilization of a long pressure plateau, without a complete occlusion of the CS, will enable prolonged and improved redistribution of the venous flow and improve the oxygenation of the border zone (penumbra) of the infarcted myocardium at risk. The improved oxygenation of the ischemic peri-infarcted area is believed to reduce infarct size and may lead to improved short- and long-term outcomes.
This is a First-In-Human study aimed to evaluate the safety and feasibility of the Booster Balloon Catheter (BBC). The study will include up to 20 patients in up to 5 centers in Israel and Europe.
After the patients sign the informed consent, all the eligibility criteria will be evaluated. If a subject is found to be ineligible, the subject will be considered a "screen failure". Subjects who meet eligibility criteria will be treated with the BBC.
The total duration of subject participation will be 30±7 days.

Genders Eligible for Study
Description
Inclusion Criteria:
Pre procedural:

Patient and physician agree to all required follow-up procedures and visits
Angiographic inclusion criteria:
- Coronary sinus diameter of 10 mm
- PCI is indicated for culprit lesion in the LAD with planned use of a stent
- Initial recanalization is successful, defined by stable culprit lesion and ≥ TIMI-2 flow and no major complications (detailed below).
Exclusion Criteria:

- Hemodynamic instability, including pulmonary edema, cardiogenic shock
- Current participation in other investigational device or drug trials that have not completed the primary efficacy endpoint follow-up parameters
- Physician discretion that the patient should not be enrolled Intra-procedural
- Coronary sinus anatomy which precludes patient from participation in the study
- Hemodynamic instability, including cardiogenic shock or treatment with inotropes or vasopressors before, or during the PCI
- Pulmonary edema

---|---|
Experimental: Booster Balloon Therapy
The Booster balloon therapy (i.e.
partial occlusion of the CS lumen with a subsequent backward pressure elevation without obstructing the CS blood flow) will start immediately after a successful PCI of the culprit coronary lesion in the LAD, with TIMI-II flow restoration.
The Booster balloon therapy will then be continued for up to 90 min, but not less than 60 min.
