“…There are some reports advocating for TICS [7,18,19]. In a porcine model, Wipperman et al recommended the use of TICS instead of external occlusion devices based on acute and chronic vascular changes [13]. However, a conflicting study was published recently reporting on endothelial denudation and damage to the underlying media due to use of TICS in a porcine model [14].…”

“…Wippermann et al have shown in an animal study that intraluminal shunts cause only moderate trauma to the vessel and may therefore be superior regarding acute and chronic intimal integrity in contrast to tournique occlusion [11,12]. In contrast, some investigators revealed that intracoronary shunts might create a greater degree of endothelial dysfunction compared to extravascular devices such as bulldog clamps or double-looped Gore-Tex suture snaring.…”

Background To determine impact of intraluminal-left anterior descending shunt to prevent myocardial damage in minimally invasive coronary artery bypass. Methods 38 patients were randomly assigned to external tournique occlusion (n = 19) or intraluminal-left anterior descending shunt group (n = 19). Blood samples for cardiac troponin T were collected at 30 minutes prior to, 6 and 24 hours after surgery. Results One patient in external tournique occlusion and two patients in intraluminal-left anterior descending shunt group were excluded from futher analysis due to preoperative cardiac troponin T level above the 99th-percentile. Postoperatively, each six patients in external tournique occlusion (33.3%) and intraluminal-left anterior descending shunt (35.3%) group were above the 99th-percentile. Two patients from each group (external tournique occlusion group 11.1% vs. intraluminal-left anterior descending shunt group 11.8%) had peak values above 10-% coeficient of variation cutoff ( p = 1). There were no significant differences in between both groups at all studied timepoints. Conclusion There was no protective effect of intraluminal shunting on myocardial damage compared to short-term tournique occlusion. It is upon the surgeon's discretion which method may preferrably be used to achieve a bloodless field in grafting of the non-occluded left anterior descending in minimally invasive coronary artery bypass.

“…There are a number of key techniques available to ensure hemodynamic and electrical stability while the anastomosis is done is one on a beating heart. The use of temporary intracoronary stents during application of distal anastomoses is one of them [22,23]. Intracoronary stents are designed to ensure distal coronary blood flow during the bypass procedure.…”

“…Many surgeons are certain of the usefulness of intracoronary stents, as long as they allow for more precise bypassing [1][2][3][4][5][6][7][8][9][10]22,23,[25][26][27][28]. The right stunt that fits the corresponding coronary artery ensures hemodynamic and electric myocardial stability, dry surgical field, and prevents the risk of sewing the rear wall of the vessel.…”

The latest literature review on application of intracoronary shunts in anastomoses for myocardial revascularization in patients with coronary heart disease has been presented here. Advantages of the use of this technique (continuous myocardial perfusion, improved anastomosis location visualization, unlimited time for bypassing), which minimize any possible complications have been analyzed.
