Primary Outcome Measures:
  • Major adverse cardiac and cerebral events (MACCE) [ Time Frame: One Year ]
    MACCE is defined as cardiac death, cerebrovascular accidents, myocardial infarction, serious arrhythmia and congestive heart failure

  • Mortality [ Time Frame: One Year ]
    All cause mortality

Secondary Outcome Measures:
  • Exercise Tolerance Test [ Time Frame: 3, 6 and 12 months ]
    Exercise tolerance to onset of moderately severe angina

  • Ejection Fraction [ Time Frame: 6 and 12 months ]
    Ejection fraction and areas of myocardial ischemia by cardiac MRI

Enrollment: 7
Study Start Date: October 2010
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TMR plus BMAC injection
Injection of bone marrow aspirate concentrate into reversibly ischemic myocardium with transmyocardial revascularization during the same open procedure.
Biological: Bone Marrow Aspirate Concentrate
Injection of up to 18 mL BMAC

Detailed Description:
Recently published information suggests the delivery of concentrated autologous bone marrow, in combination with transmyocardial revascularization (TMR) may provide synergistic effects for the reduction of angina in patients who are not treatable with conventional coronary artery bypass or percutaneous coronary intervention. This safety and feasibility study is intended to confirm the work previously done at one hospital in a larger, multicenter setting. Patients who are candidates for TMR will be asked to participate.

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

Inclusion Criteria:

  • Adult patient, 18 years of age or older, male or female.
  • Left ventricular ejection fraction greater than or equal to 40% (documented within 6 months of the TMR procedure.
  • Patient with medically refractory, stable, Class IV angina according to the Canadian Cardiovascular Society angina scale. Optimal medical therapy is defined as maximum tolerable and stable doses of beta-blockers, statins, anti-platelets and long acting nitrates without control of symptoms for at least 30 days.
  • Patient with at least a 15 cm² (or 15% of the surface area in the distal 2/3 of the left ventricle free wall to allow for a minimum of 15 TMR channels) documented region of the myocardium in the distal two-thirds of the left ventricle with reversible ischemia. Patients will be enrolled based on images used to determine eligibility for TMR within the previous 6 months. However, all patients will have baseline and follow-up MRIs taken per a standardized protocol and adjudicated by a core lab.
  • Has a documented left ventricular wall thickness of ≥8 mm.
  • Patient is not a candidate for treatment by direct coronary revascularization methods (i.e., CABG or PCI) as documented by an independent interventional cardiologist and an independent cardiothoracic surgeon on the Angiographic Screening Form.
  • Patient is able to perform the baseline exercise tolerance test (ETT).
  • Patient, if female, has no childbearing potential or has had a negative urine or serum pregnancy test within 7 days of the procedure.
  • Patient has a bone marrow aspirate total nucleated count of at least 15 x 106/mL at the time of harvest.
  • Patient has provided informed consent.

Exclusion Criteria:

  • Cannot undergo a surgical procedure, thoracotomy or general anesthesia.
  • Has any mechanical or prosthetic heart valve.
  • Has a history of bone marrow disease (especially Non-Hodgkin's Lymphoma and Myelodysplastic Syndrome) that prohibits autologous bone marrow derived cell transplantation.
  • Has severe, new onset or increasing angina. In addition, patients who cannot be weaned from intravenous anti-anginal medications for at least 48 hours preoperatively are to be excluded. Severe, new onset and increasing angina is defined as: Severe angina - angina occurring at rest and usually prolonged >20 minutes occurring within a week of presentation; new onset angina - angina of at least Canadian Cardiovascular Society Classification (CCSC) III severity with onset within 2 months of initial presentation; and increasing angina - previously diagnosed angina that is distinctly more frequent, longer in duration, or lower in threshold, (i.e., increased by at least one CCSC class within 2 months of initial presentation to at least CCSC III severity.
  • Has had a STEMI (ST Elevation Myocardial Infarction) or NSTEMI (Non-STEMI) within 4 weeks of the TMR procedure.
  • Has decompensated heart failure, or a diagnosis of NYHA Functional Class III/IV heart failure.
  • Has a hemorrhagic propensity that cannot be addressed with drug management.
  • Has severe or life-threatening arrhythmia (e.g., ventricular tachycardia or fibrillation) within one week prior to the TMR procedure.
  • Is unable to undergo a cardiac MRI procedure.
  • Has uncontrolled diabetes with HbA1C > 10%.
  • Has anemia defined as hematocrit < 33% in women and <39% in men.
  • Has moderate to severe renal dysfunction defined as serum creatinine >1.8 mg/dL.
  • Has moderate to severe liver dysfunction defined as> ALT/AST >5X the upper limit of normal.
  • Is unable or unwilling to return for follow-up.
  • Is participating in another clinical investigation within the prior 30 days.
