简要总结
The purpose of this study it to collect real world 30-day and 1-year follow-up data for patients undergoing TMR with the CardioGenesis Holmium:YAG Laser System either as a sole therapy procedure or in conjunction with coronary artery bypass graft (CABG) surgery.
The primary objective of this study is to provide ongoing clinical data regarding the characteristics of the patient population undergoing TMR in community practices. Secondary objectives include rates of postoperative mortality and MACE at 30-days and 1-year, and benefit of sustained improvement in angina at 30-days and 1-year.
The study includes two patient populations:
- Registry Group: Patients from selected centers who previously participated in the ANGINA RELIEF Registry and are eligible for a one-year, prospective follow-up;
- Prospective Group: Up to 100 new, prospectively enrolled TMR patients from selected centers.
详细描述
The study objectives are as follows:
- Track "real world" performance outcomes and physician experience using the CardioGenesis Laser System;
- Further define the disease characteristics of the population being treated;
- Examine transmyocardial revascularization (TMR) usage characteristics, including surgical procedure information, and 30-day and 1-year outcomes;
- Further assess the risk factors for adverse events at 30-days and 1-year;
- Further define MACE rates and angina scores at 30-days and 1-year. To limit the potential for bias, all patients eligible for TMR treatment who meet the Inclusion and Exclusion Criteria will be offered the opportunity to enroll in the study at participating centers.
Primary Endpoint:
- 1-year Canadian Cardiovascular Society (CCS) angina class

结局指标
主要结局
Change in Canadian Cardiovascular Society (CCS) Angina Class from Baseline (Class IV) at 1 Year.
时间窗: 1 year
Class I: Ordinary physical activity does not cause angina, such as walking and climbing stairs. Angina with strenuous or rapid or prolonged exertion at work or recreation; Class II: Slight limitation of ordinary activity. Walking or climbing stairs rapidly, walking uphill, walking or stair climbing after meals, or in cold, or in wind, or under emotional stress, or only during the few hours after awakening. Walking more than two blocks on the level and climbing more than one flight of ordinary stairs at a normal pace and in normal conditions; Class III: Marked limitation of ordinary physical activity. Walking one or two blocks on the level and climbing one flight of stairs in normal conditions and at normal pace; Class IV: Inability to carry on any physical activity without discomfort, anginal syndrome may be present at rest.
次要结局
- Rate of all cause mortality(30 days, 1 year)
- Rates of Major Adverse Cardiovascular Events (MACE)(30 days, 1 year)
