Coronary–coronary bypass graft was first performed by Rowland and Grooters. This technique can be performed between two segments of the same coronary artery using saphenous vein grafts or free arterial grafts in on/off-pump coronary artery bypass grafting, also can be an alternative safe technique in some cases as calcified ascending aorta, porcelain aorta and insufficient graft length. The coronarycoronary bypass graft can provide nearly the same flow rate as conventional coronary artery bypass graft, another advantage this technique is that we can use to decrease sternal and respiratory morbidity. we performed this technique to a 55-year-old woman to whom coronary angiography showed critical three-vessel disease, using a free segment of right internal mammary artery, combined to conventional coronary artery bypass graft. The postoperative course was uneventful with the absence of ischemic lesions and the grafts were patent at 6 months after procedure.

Abstract Background Widespread use of intraoperative epicardial ultrasonography (ECUS) for quality assessment of coronary artery bypass graft anastomoses during coronary artery bypass grafting (CABG) has not occurred - presumably due to technological and practical challenges including the need to maintain stable and optimal acoustic contact between the ultrasound probe and the target without the risk of distorting the anastomosis. We investigated the feasibility of using a stabilizing device during ultrasound imaging of distal coronary bypass graft anastomoses in patients undergoing on-pump CABG. Imaging was performed in both the longitudinal and transverse planes. Methods Single-centre, observational prospective feasibility study among 51 patients undergoing elective, isolated on-pump CABG. Ultrasonography of peripheral coronary bypass anastomoses was performed using a stabilizing device upon which the ultrasound transducer was connected. Transit-time flow measurement (TTFM) was also performed. Descriptive statistical tests were used. Results Longitudinal and transverse images from the heel, middle and toe were obtained from 134 of 155 coronary anastomoses (86.5%). After the learning curve (15 patients), all six projections were obtained from 100 of 108 anastomoses scanned (93%). Failure to obtain images were typical due to a sequential curved graft with anastomoses that could not be contained in the straight cavity of the stabilizing device, echo artefacts from a Titanium clip located in the roof of the anastomoses, and challenges in interpreting the images during the learning curve. No complications were associated with the ECUS procedure. The combined ECUS and TTFM resulted in immediate revision of five peripheral anastomoses. Conclusions Peroperative use of a stabilizing device during ultrasonography of coronary artery bypass anastomoses in on-pump surgery facilitates imaging and provides surgeons with non-deformed longitudinal and transverse images of all parts of the anastomoses in all coronary territories. Peroperative ECUS in addition to flow measurements has the potential to increase the likelihood of detecting technical errors in constructed anastomoses. Trial registration The study was registered on September 29, 2016, ClinicalTrials.gov ID: NCT02919124.

Introduction: The Mean Platelet Volume (MPV) is a marker of platelet size with increased platelet activation. An elevated MPV is associated with major cardiac adverse events after Coronary Artery Bypass Graft (CABG) surgery. Effect of preoperative MPV on outcome of in-hospital patients after coronary artery bypass graft surgery was investigated in this study. Objective: To investigate the association of preoperative MPV with in-hospital outcome of patients after CABG surgery. Materials and Methods: An observational prospective study was carried out in the Department of Cardiovascular Surgery, National Institute of Cardiovascular Diseases (NICVD), Dhaka during the period from July 2012 to June 2014. Preoperative mean platelet volume was obtained prospectively in 81 consecutive patients undergoing conventional coronary artery bypass surgery. The patients were divided into two groups according to normal and elevated MPV at 10.60 femtolitre (fL) cut off level. Postoperative mortality and major adverse events were recorded in the early postoperative period. Results: Combined adverse events including post operative Myocardial Infarction (MI), arrhythmia, bleeding and death occurred in 27 patients (33.3%) during the early follow-up. The preoperative mean platelet volume levels were found to be associated with postoperative adverse events (p<0.05). In multivariate logistic regression models, the preoperative mean platelet volume levels was found strong independent predictor of combined adverse events after surgery (OR 1.968, p=0.008). Conclusion: Mean platelet volume is simple, readily available and cost effective tool and useful in predicting the postoperative adverse events in patients undergoing coronary artery bypass graft surgery.
