Aims Visual estimation is the most commonly used method to evaluate the degree of coronary artery stenosis prior to coronary artery bypass grafting. In interventional cardiology, the use of fractional flow reserve (FFR) to guide revascularization decisions has become routine. We investigated whether the preoperative FFR measurement of coronary lesions is associated with anastomosis function 6 months after surgical revascularization using a multiarterial grafting strategy. Methods and results In this prospective double-blind study, 67 patients were enrolled from two institutions in Europe and Canada. From these patients, 199 coronary lesions were assessed visually and with FFR at the time of the preoperative angiogram. All patients received coronary revascularization using multiple arterial grafts. A post-operative 6-month angiogram was performed to assess anastomosis functionality using a described angiographic method. The primary outcome was the association between preoperative FFR values and anastomosis function 6 months after surgery. Preoperative FFR was significantly associated with 6-months anastomotic function for all conduits and for all targets (P  <  0.001). An FFR value of ≤0.78 was associated with an anastomotic occlusion rate of 3%. Conclusion We found a significant association between the preoperative FFR measurement of the target vessel and the anastomotic functionality at 6 months, with a cut-off of 0.78. Integration of FFR measurement into the preoperative diagnostic workup before multiarterial coronary surgical revascularization leads to improved anastomotic graft function.

Robotically assisted closure of a patent ductus arteriosus is comparable with closure by means of the videothoracoscopic technique. However, it requires a longer operative time because of the increment in complexity.

MIDCAB and DES implantation showed similar rates of survival but despite an expected lower rate of reintervention on the targeted vessel with DES use, a highly significant higher MACCE rate was observed in the PCI group at 5-year follow-up.

Performance of an exclusive composite BITA off-pump revascularization strategy optimal and sustained long-term protection from MACCE.

Utilization of the BIMA-Y configuration was associated with improved survival when compared to BIMA grafting with additional vein grafts. Further studies are necessary to evaluate the efficacy of BIMA-Y grafting against other means of providing complete arterial revascularization.
