“…The authors suggested that a possible explanation could have been related to the lower vascular resistance of the Y graft system and to the active dilatation of the LITA. Similar findings, supporting the safety of a single LIMA inflow, were confirmed also by Gatti and colleagues [33].…”

“…Apart from such peculiar conditions, detractors of the composite arterial grafting raised doubts about the flow adaptability of the left IMA when used as the only inflow for composite arterial grafting. Nevertheless, there is ample evidence from several studies published in the past decade [29][30][31][32][33] that the left internal thoracic artery (LITA) shows a marked adaptability to flow dynamics. In particular, an elegant study by Affleck and colleagues [30] identified a consistent flow reserve in the LIMA-radial composite grafting, as demonstrated by their intraoperative flow recordings for each limb of the T graft before and after distal anastomoses in 204 patients.…”

“…Similarly there was adequate flow at rest and with maximal hyperemia throughout two years of serial study [19]. Other studies of flow adequacy in composite RA grafts have not revealed evidence of myocardial ischemia at rest or with stress [20,21]. Initial physiologic vasodilation and subsequent conduit remodeling achieve definitive flow adequacy of the RA composite graft in which the limiting link is actually the proximal left ITA which must supply both conduits and theoretically the entire myocardium if the right coronary and left main were occluded [22].…”

“…However there are data which support the hemodynamic adequacy of composite grafts which are presented below. Intraoperative and late postoperative hemodynamic studies suggest that the T-graft, with either ITA or RA, has resting flow and coronary flow reserve which is within the normal range which is the result of physiologic vasodilation and conduit remodeling [14-20]. The complexity of the T-graft versus a Y-graft is another reason why it is not favored.…”

“…A variety of noninvasive and minimally invasive techniques are available for intra-and (or) postoperative assessment of graft patency. In a surgical setting, luminal diameter and vascular flow in large and medium vessels can be estimated via X-ray angiography, Doppler ultrasonography, fluorescence imaging, and transit-time flowmetry (Balacumaraswami et al 2005;Bourassa et al 2003;Gatti et al 2005;Iaco et al 2001;Langerak et al 1999). On the other hand, tissue perfusion can be evaluated using positron emission tomography, contrast agent-aided MRI, and near-infrared (NIR) fluorescence imaging (Balacumaraswami and Taggart 2004;Muhling et al 2003;Pasquet et al 1999;Sakuma et al 1999).…”
