Multicenter Randomised Prospective Study for External Support Mesh VEST of Venous Coronary Grafts on the Right Territory

Multicenter Randomised Prospective Study for External Support Mesh VEST of Venous Coronary Grafts on the Right Territory: Mid-term Clinically Driven Re-rivascularization Events Comparison Between Sites Treated With VEST, Sites Treated With Bare Vein, Sites Treated With Other Conduits and de Novo Lesions on the Native Vessels

Multicentre randomised prospective study aimed at verifying medium-term patency of venous grafts on the right coronary artery territory, by clinical and/or instrumental follow-up with particular attention to clinically driven re-revascularisation events regarding the site of new lesions (granularly comparing sites already treated with VEST, sites treated with bare vein, sites treated with other conduits, de novo lesions on the native).

Inclusion Criteria:

• combined or isolated interventions
• adequate vein calibre
• adequate graft flowmetry

Exclusion Criteria:

• inability to implant due to calibre disparity or inadequate flowmetry
