Long-Term Patency of Venous Conduits Targeting the Right Coronary Artery System-Single Is Superior to Sequential bypass Grafting.

ABSTRACT:

Objective

Little is known about the fate of bypass grafts to the right coronary system. To investigate the long-term patency of venous bypass grafts directed to the right coronary artery (RCA) based on postoperative angiograms and to identify predictors of graft occlusion.

Methods

In this single-center study, all patients who underwent coronary angiography from 2005 to 2021 after previously undergoing isolated coronary artery bypass grafting (CABG) were included. The primary endpoint was graft occlusion over a median follow-up of 9.1 years.

Results

Among a total of 1106 patients (17.0% women, 64 (57-71) years median age), 289 (26.1%) received a sequential vein graft and 798 (72.2%) a single graft. Multivariate regression revealed age (HR 1.019, CI 95% 1.007-1.032), th
