	Group	Frequency	Percentage(%)
Bypass method	Single bypass (Group A)	187	71.9
	Right crown sequential group (Group B)	43	16.5
	Sequential group with other systems (Group C)	30	11.5
	In total	260	100
Right crown bypass material selection	Great saphenous vein	286	92.3
	Radial artery	17	5.5
	Internal mammary artery	6	1.9
	Mix bypass^a	1	0.3
	In total	310	100
Right coronary target vessel site	Right crown trunk	90	29.1
	Post-fall	147	47.6
	Posterior left ventricular branch	72	23.3
	In total	309	100
Coronary CT bypass occlusion in the week after operation	Single bypass group	11^b	91.7
	Sequential Group	0	0
	Sequential group with other systems	1	8.3

^aThe hybrid graft is the posterior branch anastomosis after the right internal mammary artery is connected to the saphenous vein;
^bOf the 11 cases, 4 were poorly developed, 4 were occluded (grade O), 1 was moderate to severe stenosis (grade B), and 2 were moderately stenotic (grade B)
