Equipoise between radial artery and right internal thoracic artery as the second arterial conduit in left internal thoracic artery-based coronary artery bypass graft surgery: a multi-institutional study

摘要

OBJECTIVES: Multiple arterial coronary artery grafting (MABG) improves long-term survival compared with single arterial CABG (SABG), yet the best second arterial conduit to be used with the left internal thoracic artery (LITA) remains undefined. Outcomes in patients grafted with radial artery (RA-MABG) versus right internal thoracic artery (RITA-MABG) as the second arterial graft were compared with SABG.
