Background This retrospective propensity matched study investigated the impact of age on the survival benefit from a second arterial conduit to the left-sided circulation. Methods Data for isolated coronary artery bypass surgery were collected from October 2004 to March 2014. All patients with an internal mammary artery graft to left anterior descending artery and additional arterial or venous graft to the circumflex circulation were included. Propensity matching was used to balance co-variates and generate odds of death for each observation. Odds ratios (venous vs. arterial) were charted against age. Results The in-hospital mortality rate was 1.12% (arterial) vs. 1.24% (venous) (p = 0.77). The overall 10-year survival was 74.6% (venous) vs. 82.6% (arterial) (p = 0.001). A total of 1226 patients were successfully matched to the venous or arterial (second conduit to circumflex territory after left internal mammary artery to left anterior descending artery) cohorts. Odds ratio for death (venous to arterial) showed a linear decremental overall survival benefit for the second arterial graft to circumflex circulation with increasing age. Conclusions The survival benefit of a second arterial graft persists through all age groups with a gradual decline with increasing age over the decades. Elderly patients should not be denied a second arterial graft to the circumflex circulation based on age criterion alone.

Robotic assistance has enabled coronary artery bypass surgery to be performed safely in a completely endoscopic fashion, but diffusely diseased target vessels may pose a technical challenge. We present a case in which coronary endarterectomy was performed on the left anterior descending coronary artery during a two-vessel totally endoscopic coronary artery bypass procedure. A 52-year-old woman presented with intermittent substernal pain. Preoperative studies showed diffuse disease in the left coronary artery system. Bilateral internal mammary arteries were harvested robotically using a skeletonized technique in a completely endoscopic fashion. Cardiopulmonary bypass was achieved via peripheral cannulation, and the heart was arrested with intermittent cold antegrade hyperkalemic blood cardioplegia delivered via an ascending aortic occlusion balloon catheter. The first obtuse marginal anastomosis was performed. The left anterior descending coronary artery was diffusely diseased and heavily calcified. An end-to-side anastomosis was attempted to the right internal mammary artery with unsatisfactory results. A localized coronary endarterectomy was performed, and an extended anastomosis was completed using the right internal mammary artery. The patient recovered uneventfully and was discharged home on postoperative day 6. Diffuse coronary artery disease was once thought to be a prohibitive challenge for minimally invasive coronary bypass procedures. This case demonstrates that local coronary endarterectomy is feasible and safe in robotic totally endoscopic coronary artery bypass surgery.

Abstract Objectives To compare semi-skeletonized with pedicled harvesting technique of the internal mammary artery for coronary artery bypass surgery. Method A comprehensive literature search was performed on PubMed, Cochrane database, Embase, Google Scholar and Ovid identifying articles that compared semi-skeletonised to pedicled internal mammary artery in the use of coronary artery bypass surgery. Databases were evaluated and assessed from inception to July 2020. Results Only five studies fulfilled the criteria for this review. There was no reported incidence of sternal wound infection, myocardial infarction, or mortality. The length of the IMA graft was longer in the semi-skeletonized group compared to the pedicled group, 16.06cm versus 14.63cm respectively (p < 0.001). The intraoperative diastolic flow was significantly greater in the semi-skeletonized grafts than in the pedicled grafts during (p = 0.003) and after (p = 0.005) cardiopulmonary bypass. The incidence of pleural effusion (pedicled, 52.6%; semi-skeletonized, 23.6%; p = 0.002) and atelectasis (pedicled, 42.1%; semi-skeletonized, 20.0%, p = 0.015) were significantly higher in pedicled group. Post-operative chest tube drainage was significantly higher in the pedicled group (608 ± 58 mL compared to 470 ± 48 mL; p = 0.027). Additionally, FEV1 was significantly decreased in the pedicled group 6 days after surgery (pedicled:76.0% ± 1.6%; semi-skeletonized: 83.2% ± 1.6%; p = 0.020). Conclusions These results demonstrate that the semi-skeletonized preparation technique is associated with satisfactory outcomes during harvesting the internal mammary artery. Yet, due to limited numbers of studies, there is need for larger comparative studies to assess post-operative outcomes with a longer period of follow up.
