About this study

Official title: A Multi-Center Single Arm One Year Prospective Follow-Up of Patients Treated With the CryoLife CardioGenesis Holmium:YAG Laser System for Transmyocardial Revascularization (The TMR 365 Study)

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.
Read the detailed description

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

Secondary Endpoints:

  • All-cause mortality at 30-day and 1-year.
  • Rates of major adverse cardiovascular events (MACE) at 30-days and 1-year, defined as the incidence of cardiac-related death, myocardial infarction (Q-wave and non Q-wave), congestive heart failure, cerebrovascular accident, and serious arrhythmia.

The definitions for MACE events are as follows:

  • Cardiac-related death: any death that is not clearly attributable to a non-cardiac cause, and includes death due to any of the following: acute myocardial infarction, heart failure, cardiogenic shock, pulmonary edema, cardiac tamponade, arrhythmia, or post-procedural complications (i.e., bleeding).
  • Q-wave myocardial infarction: the appearance of new Q waves of 40 or more milliseconds in 2 or more contiguous leads and elevation of CK-MB.
  • Non Q-wave myocardial infarction: the elevation of total CK more than twice normal with elevated CK-MB.
  • Congestive heart failure: Symptoms of pulmonary vascular congestion or a low output state that is due to left ventricular failure and is new in onset or results in re-hospitalization.
  • Cerebrovascular accident: Any sudden development of neurological deficits due to vascular lesions of the brain such as hemorrhage, embolism, or thrombosis that persists for > 24 hours.
  • Serious arrhythmia: Supra-ventricular or ventricular arrhythmias that require sustained intravenous pharmacologic treatment, temporary or permanent pacing, or immediate electrical cardioversion or defibrillation. Arrhythmias resulting in syncope, myocardial ischemia, or death are also classified as serious.
  • Any other serious operative complications related to the procedure: example: major bleeding requiring transfusion.

Study groupRoleWhat they receive
Registry GroupPatients previously enrolled in the ANGINA RELIEF Registry who are eligible for a 1-year, prospective follow-up (date of ANGINA RELIEF Registry TMR procedure performed within 12-18 month follow-up window).
Prospective GroupA group of up to 100 new, prospectively enrolled patients from active centers that receive TMR with the CardioGenesis Laser System and complete a 30-day and 1-year follow-up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Canadian Cardiovascular Society (CCS) Angina Class from Baseline (Class IV) at 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.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Class IV Angina, run by CryoLife, Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Canadian Cardiovascular Society (CCS) Angina Class from Baseline (Class IV) at 1 Year. (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2021.
