Limitations
Several limitations of our study should be recognized. Firstly, this
study was its descriptive nature, using a relatively small cohort of
patients at a single institution. Secondly, blood flow parameters
measured by TTFM and early prior to discharge graft patency do not
reflect the all of the advantages of the effect of the grafting
strategy; in addition, major cardiovascular and cerebrovascular adverse
events, revascularization events and the long-term graft patency can
reflect the advantage of grafting strategy to the LAD. These other
indicators were not included in this study.
