Further study details as provided by Silesian Centre for Heart Diseases:

Primary Outcome Measures:
  • 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. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Postprocedure and follow up angiographic measurements as patency of grafts and restenosis in revascularized segments [ Time Frame: 1 year ]
  • Assessment of quality of life of alive study participants according to SF-36 Health Survey version 2 [ Time Frame: 1 year ]
  • Cost-effectiveness defined as a cost of revascularization procedure and costs of hospitalizations in both groups. [ Time Frame: 1 year ]

Enrollment: 200
Study Start Date: November 2009
Study Completion Date: October 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Hybrid revascularization 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
Active Comparator: Coronary Artery Bypass Grafting Procedure: Coronary Artery Bypass Grafting
Coronary artery bypass grafting with sternotomy on or off the pump at discretion of the operator.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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
