Outcomes of Total Arterial Coronary Artery Bypass Grafting (MOZART)

July 9, 2020 updated by: Cristiano Spadaccio, University of Glasgow

Multicentric Registry Database of Total Arterial CABG

"real-life" retrospective multicentric database for the analysis of the long term outcomes of total arterial CABG in comparison to saphenous vein based CABG

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This aim of this registry is to create a multi centric database for the analysis of basic long term outcomes and immediate postoperative outcomes of total arterial CABG in comparison to saphenous vein based CABG. The registry will include both on pump and off pump surgery. The registry is intended to capture the "real-life" picture of the CABG scenario among centers worldwide

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Survival
Time Frame: data collection every year up to 5 years after operation/entry in the registry
Long term survival
data collection every year up to 5 years after operation/entry in the registry
MACCEs
Time Frame: data collection every year up to 5 years after operation/entry in the registry
Major cardiac events (myocardial infarction, stroke, readmission for CHF)
data collection every year up to 5 years after operation/entry in the registry
target vessel revascularization
Time Frame: data collection every year up to 5 years after operation/entry in the registry
readmission for revascularization due to graft failure
data collection every year up to 5 years after operation/entry in the registry
Wound infection

Readmission for wound infection (superficial sternal wound infection, deep sternal wound infection, saphenous vein related wound infection, need for VAC therapy, need for surgical debridment, need for prolonged antibiotic therapy)
data collection every year up to 5 years after operation/entry in the registry

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
