Is it better to use the radial artery as a composite graft? Clinical and angiographic results of aorto-coronary versus Y-graft1

Abstract

The RA provides the same clinical and angiographic results both as aorto-coronary and composite Y-graft with the left ITA. When the RA is used as Y-graft the procedure is more technically demanding and a greater number of distal coronary anastomoses is possible. RA grafts to targets with stenosis < or = 70% appear to be at risk of failure.
