Recruitment information / eligibility

Status Completed
Enrollment 200
Est. completion date October 2013
Est. primary completion date May 2013
Accepts healthy volunteers No
Gender Both
Age group 18 Years and older
Eligibility Inclusion Criteria:

- Age 18 or more

- Angiographically confirmed multivessel CAD with involved LAD and critical (>70%)lesion in at least one (apart LAD) major epicardial vessel amenable to both PCI and CABG

- Indication for revascularization based upon symptoms of angina and/or objective evidence of myocardial ischaemia

- Patient is willing to comply with all follow-up visits

- Patient signed an Informed Consent

Exclusion Criteria:

- Severe congestive heart failure (class III or IV according to NYHA, or pulmonary edema, cardiogenic shock) at the time of enrollment

- Prior surgery with the opening of pericardium or pleura

- Prior stroke (within 6 months)or more than 6 months if there are substantial neurological defects

- Prior history of significant bleeding (within previous 6 months) that might be expected to occur during PCI/CABG related anticoagulation

- One or more chronic total occlusions in major coronary territories

- Left main stenosis (at least 50% diameter stenosis)

- Acute ST-elevation MI within 72 hours prior to enrollment requiring revascularization

- Planned simultaneous surgical procedure unrelated to coronary revascularization (e.g. valve repair/replacement, aneurysmectomy, carotid endarterectomy or carotid stenting)

- Contraindication to either CABG, MIDCAB or PCI/DES because of a coexisting clinical condition

- Significant leukopenia, neutropenia, thrombocytopenia, anemia, or known bleeding diathesis.

- Intolerance or contraindication to aspirin or both clopidogrel and ticlopidine

- Extra-cardiac illness that is expected to limit survival to less than 5 years e.g. oxygen-dependent chronic obstructive pulmonary disease, active hepatitis or significant hepatic failure, severe renal disease

- Suspected pregnancy. A pregnancy test will be administered prerandomization to all women of child-bearing age

- Concurrent enrollment in another clinical trial

- Patient inaccessible for follow-up visits required by protocol

Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment


Intervention

Procedure:
Hybrid revascularization
First stage: implantation of the internal mammary artery into LAD in MIDCAB/TECAB procedure Second stage: PCI with drug eluting stents in other coronary arteries qualified for revascularization within 36 hours after surgery
Coronary Artery Bypass Grafting
Coronary artery bypass grafting with sternotomy on or off the pump at discretion of the operator.

Outcome

Type Measure Description Time frame Safety issue
Primary Possibility defined by means of (1) a % of pts with complete hybrid procedure according to study protocol, and (2) a % of conversion to standard CABG. Safety defined as a occurrence of MACE such as death, MI, stroke, TVR, or major bleeding. 1 year Yes
Secondary Postprocedure and follow up angiographic measurements as patency of grafts and restenosis in revascularized segments 1 year Yes
Secondary Assessment of quality of life of alive study participants according to SF-36 Health Survey version 2 1 year No
Secondary Cost-effectiveness defined as a cost of revascularization procedure and costs of hospitalizations in both groups. 1 year No
