The reason for 42 patients who received SVG for LAD revascularization
There were total 42 patients who received SVG for LAD revascularization, the reasons the LIMA cannot be used are shown in Table 4. There were 5 cases that LIMA and SVG were both used for LAD; among 5 cases, there was no difference between the SVG-LAD and LIMA-LAD in term of MGF( -vs -P=0.842),PI(( -vs -P=0.114) and DF(( -vs -P=0.315)(Table 5). There were 6 cases that LIMA was used for non-LAD arteries(DIAG); among 6 cases, there was no difference between TTFM SVG-LAD and LIMA-DIAG in terms of PI(-vs -P=0.729),MGF(P=0.154)and DF(P=0.332)(Table 5).
