Hybrid Revascularisation by Combined Coronary Artery Bypass Graft (CABG) and PCI in Multivessel Coronary Disease — HYBRID  

Coronary Artery Disease (CAD) Clinical Trial

Official title: Hybrid Revascularisation by Combined CABG and PCI in Multivessel Coronary Disease. An Observational Study.

Status Terminated

Clinical Trial Summary

The present study is designed as a prospective, single centre, open label, observational trial.

The study will collect information about the medical care patients receive during their planned procedure(s). No new testing or procedures will be done.

Patients elected for hybrid revascularization will be asked their written consent to the use of their personal data.

Left internal mammary artery to the Left Anterior Descending Coronary Artery (LIMA-LAD)surgical revascularization will be performed first, followed by percutaneous revascularization of the other vessels in the frame of the same hospitalization.

After discharge patients will attend clinic visits at 30 days and 12 months, as per usual clinical practice, and will be contacted by phone at 6 months after procedure. Angiographic follow-up will be performed in symptomatic patients, as clinically indicated.

Clinical Trial Description

Hybrid coronary revascularization integrates the positive features of both Percutaneous Coronary Intervention (PCI) and Coronary Artery Bypass Graft (CABG), combining the durability of Left Anterior Descending Coronary Artery (LIMA) coronary bypass with the minimal invasiveness and lower risk of percutaneous intervention. Thereby it might represent a better option in a sizeable proportion of patients.

Candidate patients in whom hybrid revascularization would be advantageous are several subgroups of Coronary Artery Disease (CAD) patients that are increasing in numbers: the elderly patients with a high risk of mortality and/or morbidity for CABG, patients with significant disabilities and patients in whom treatment durability is important but a significantly invasive approach is not an option.

There are several potential advantages of the hybrid procedure over conventional CABG in selected patients. These advantages include the avoidance of cardiopulmonary bypass-related morbidity, no aortic manipulation with the LIMA-LAD with the beating heart procedure, less blood loss and decreased transfusions, a shorter recovery time than after conventional CABG and patient's preference for "minimally invasive" surgery.

The investigators hypothesize that in selected patients with diffuse coronary disease, a "hybrid" approach employing a staged revascularisation procedure may allow to lower the surgical risk, increase the completeness and effectiveness of revascularisation and, hopefully, to improve immediate and long term outcome.

To test this hypothesis, a well designed, properly sized, prospective, randomized study is needed. Available data, however, do not provide sufficient information to speculate on a clinically meaningful, yet achievable, effectiveness.

Aim of this observational study is therefore to collect more information on the target population, the clinical outcomes and optimal management in order to inform the design of a comparative effectiveness trial. ;
