Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to compare the safety and effectiveness of blood clot (thrombus) removal in subjects presenting with ST-segment elevation myocardial infarction (STEMI) with the enVast coronary system versus conventional intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A prospective, multi-center, randomized clinical trial designed to assess the safety and effectiveness of the enVast coronary thrombectomy system as an adjunctive measure to conventional intervention in subjects presenting with ST-segment elevation myocardial infarction (STEMI).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Thrombectomy Arm

enVast stent deployed at occlusion site as first measure to obtain reperfusion and withdraw the clot

Group Type EXPERIMENTAL

enVast stent

Intervention Type DEVICE

In addition to conventional treatment, the treating physician will deploy as the first measure to obtain reperfusion, a enVast stent at the occlusion site in order to withdraw the clot.

Conventional Treatment Arm

Treatment strategies may include balloon angioplasty, manual aspiration thrombectomy and/or coronary stenting.

Group Type EXPERIMENTAL

conventional treatment

Intervention Type PROCEDURE

Treatment strategies may include balloon angioplasty, manual aspiration thrombectomy and/or coronary stenting.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age ≥ 18 years
2. Chest pain for \> 20 min with an electrocardiographic ST-segment elevation ≥ 1 mm in two or more contiguous electrocardiogram (ECG) leads or an infero-lateral myocardial infarction (MI) with ST segment depression of ≥ 1 mm in ≥ 2 of leads V1-3 with a positive terminal T wave.
3. TIMI Thrombus Grade ≥ 3 in the infarct related artery. In cases where TIMI Thrombus Grade is equal to 5 (i.e. TIMI 0 flow in the infarcted artery), TIMI Thrombus Grade of at least 3 has to be re-confirmed with AWI. Patients showing TIMI Thrombus Grade of less than 3 upon AWI are no longer eligible for randomization.
4. Start of intervention within 8 h of symptom onset
5. Subject is willing and able to provide informed consent prior to the intervention

Exclusion Criteria

1. Unconscious patients
2. Infarct related artery diameter, at visual assessment, smaller than 2.5 mm
3. Presence of severely calcified plaque(s) proximal to or at the site of the culprit lesion(s)
4. Presence of extreme vessel tortuosity proximal to or at the site of the culprit lesion(s)
5. Women of child-bearing potential (e.g. below 55 years of age, who have not undergone tubal ligation, ovariectomy or hysterectomy and last menstruation within the last 12 months)
6. Stent thrombosis as culprit lesion
7. Previous myocardial infarction in the same territory (i.e. same target vessel)
8. Participation in another interventional clinical trial
