Effect of Transmyocardial Laser Revascularization on Myocardial Perfusion and Left Ventricular Structure by Cardiovascular Magnetic Resonance Imaging and Dynamic Volumetric Computed Tomography
The primary goal of this study is to better understand how Transmyocardial Laser
Revascularization (TMR) affects the functioning of the heart and, in turn, relieves angina
in individuals with coronary heart disease using Magnetic Resonance (MR) images and Computed
Tomography (CT) images in some patients.
Inclusion Criteria:
- Male or female 18 years of age or over
- Patients with medically refractory, severe, class III or IV angina based on the
Canadian Cardiovascular Society angina scale as determined by a physician
- Ejection fraction 25% or greater
- Patients with significant ischemia in the myocardium and who are NOT candidates for
treatment by direct coronary revascularization methods (i.e., CABG or PCI)
- Ability and willingness to consent and Authorization for use of PHI
Exclusion Criteria:
- Patient cannot undergo a surgical procedure or general anesthesia
- Patient not eligible for CMR study
- Severe unstable angina
- Q-wave MI within 3 weeks prior to TMR
- NQWMI within 2 weeks prior to TMR
- Decompensated heart failure (class III/IV) at the time of procedure
- Known increased bleeding risk
- Implanted pacemaker or defibrillator
- Clinically unstable arrhythmia
- Not able or willing to adhere to the study tests and procedures
- Inability or unwillingness to consent and Authorization for use of PHI
