Autologous Grafts

During the last decade many countries have witnessed a dramatic increase in the number of patients undergoing coronary artery bypass grafting. As a consequence, the number of patients with insufficient or inadequate autologous vessels suitable for use as coronary artery grafts is also increasing. These patients may include those who have had previous heart operations, as well as those with bilateral varicose veins and phlebectomy. Given the shortage of autologous grafts, prosthetic and biological conduits are available for use in CABG. However, a small-diameter vascular prosthesis with acceptable long-term patency still remains the cherished wish for cardiovascular surgeons.

Objective With advances in robotic instrumentation and technology, both robotically assisted minimally invasive direct coronary artery bypass (RMIDCAB) and totally endoscopic coronary artery bypass (TECAB) have been widely used over the past 20 years. Graft patency is the most important outcome in coronary bypass surgery and is associated with long-term prognosis. In this article we reviewed all experts’ studies in the field of robotic assisted coronary artery bypass and investigated graft patency in patients who underwent RMIDCAB or TECAB. Methods We performed a literature search in PubMed from 1999 to 2018 using the terms “Robotic” and “Coronary bypass” and/or “Minimally invasive” and/or “Totally endoscopic.” Of the articles found, studies investigating graft patency were specifically selected. Results In 33 articles, a total of 4,000 patients underwent robotic assisted coronary artery bypass surgery either by a RMIDCAB (2,396) or by a TECAB (1,604) approach. The graft patency was assessed by invasive angiography or computed tomographic angiography in all studies. The mean graft patency at early (<1 month), midterm (<5 years), and long-term (>5 years) follow-up was 97.7%, 96.1%, and 93.2% in RMIDCAB and 98.8%, 95.8%, and 93.6% in TECAB, respectively. Conclusions The graft patency of robotic assisted coronary artery bypass was equivalent to reported outcomes of the conventional approach. These results should encourage the adoption of robotic approaches in coronary bypass surgery.

Harvesting Technique

One of the key aspects to obtain good long-term outcomes after coronary artery bypass grafting is graft quality. Meticulous graft harvesting is an important technical aspect in successfully performing high-quality coronary surgery and is associated with improved long-term graft patency. Hence, developing surgical skills in this necessary surgical step is of utmost importance in coronary bypass surgery. The following video tutorial presents a step-by-step audiovisual description of the skeletonized harvesting technique of the left internal mammary artery, open and endoscopic radial artery harvesting, and open saphenous vein graft harvesting.

<strong>Background</strong>: Minimally invasive bypass grafting surgery has entered the clincal routine in several centers around the world, with an increasing popularity in the last decade. In our study, we aimed to make a comparison between minimally invasive coronary artery bypass grafting surgery and conventional bypass grafting surgery in isolated proximal left anterior descending artery (LAD) lesions. <br /><strong>Methods</strong>: Between January 2004 and December 2011, patients with proximal LAD lesions, who were treated with robotically assisted minimally invasive coronary artery bypass surgery and conventional bypass surgery, were included in the study. In Group 1, coronary bypass with cardiopulmonary bypass and complete sternotomy were applied to 35 patients and in Group 2, robotically assisted minimally invasive bypass surgery was applied to 35 patients. The demographic, preoperative, perioperative, and postoperative data were collected retrospectively.<br /><strong>Results</strong>: The mean follow-up time of the conventional bypass group was 5.7 ± 1.7 years, whereas this ratio was 7.3 ±1.3 in the robotic group. There was no postoperative transient ischemic attack (TIA), wound infection, mortality, or need for intra-aortic balloon pump (IABP) in any of the patients. In the conventional bypass group, blood transfusion and ventilation time were significantly higher (P &lt; .05) than in the robotic group. The intensive care unit (ICU) stay and hospital stay were remarkably shorter in the robotic group <br />(P &lt; .01). The postoperative pneumonia rate was significantly higher (20%) in the conventional bypass group <br />(P &lt; .01). Postoperative day 1 pain score was higher in the robotic group (P &lt; .05), however, postoperative day 3 pain score in the conventional bypass group was higher (P &lt; .05). Graft patency rate was 88.6% in the conventional bypass group whereas this ratio was 91.4% in the robotic bypass group, which was not clinically significant (P &gt; .05).<br /><strong>Conclusion</strong>: In isolated proximal LAD stenosis, robotic assisted minimally invasive coronary artery bypass grafting surgery requires less blood products, is associated with shorter ICU and hospital stay, and lesser pain in the early postoperative period in contrast to conventional surgery. The result of our studies, which showed similarities to the past studies, lead us to recognize the importance of minimally invasive interventions and the need to perform them more frequently in the future.

Background In recent years, the invasiveness of coronary reconstruction has been markedly reduced. Awake off-pump coronary artery bypass (AOCAB), coronary bypass surgery with thoracic epidural anesthesia (TEA) without general anesthesia and cardiopulmonary bypass), has been reported in the literature. Because the details of this technique are still unclear, we evaluated its usefulness by examining the autonomic neural state and the incidence of arrhythmia. Methods Fifty-five patients who underwent elective coronary artery bypass grafting (CABG) between April and December 2003 were included in the study. Patients who underwent CABG under high TEA alone comprised group A, those who underwent CABG under general anesthesia combined with TEA comprised group B, and those who underwent CABG under general anesthesia alone comprised group C. Holter electrocardiography was performed before and after surgery, and perioperative electrocardiograms were recorded (before surgery and during surgery, postoperative days 0–3, and postoperative day 7). On obtained electrocardiograms, the autonomic neural state was evaluated by analysis of heart rate variability, and the incidence of atrial fibrillation. Results Concerning the autonomic neural state, sympathetic inhibition was observed during TEA in both groups A and B. After discontinuation of TEA, sympathetic activity recovered. Vagal activity was not inhibited in group A, but decreased during surgery and gradually recovered after surgery in group B. Evaluation of the balance between sympathetic and vagal activities showed that sympathetic activity became predominant rapidly on postoperative day 2 in group B but gradually after surgery in group A. The incidence of postoperative atrial fibrillation was the highest in group B. Conclusions In AOCAB, because there is no vagal inhibition, vagal dominance can be maintained after surgery. This may be associated with the lower incidence of postoperative atrial fibrillation in group A compared with group B. Further studies are necessary to evaluate the details of AOCAB.

Background Surgical site infections can have a significant impact on cardiac surgical outcome. The liver plays an important role in infection prevention. This study aimed to retrospectively determine whether transient postoperative liver dysfunction after coronary bypass surgery increased surgical site infections. Methods A modified version of the Schindl scoring scale for liver dysfunction was adapted to objectively quantify transient liver dysfunction in the first 7 days after on-pump coronary artery bypass grafting. A retrospective analysis of clinical outcomes at 30 months postoperatively was performed on data of 575 patients who underwent coronary artery bypass between 2014 and 2016. The patients were categorized into a liver dysfunction group (Schindl score ≥ 4) and a non-liver dysfunction group (Schindl score < 4). Results The liver dysfunction group (47.3%) had significantly more patients who were obese, current smokers, and had diabetes, renal impairment, and peripheral vascular disease. Surgical site infections occurred predominantly in the liver dysfunction group (12.1% vs. 0.3%, p < 0.001). The independent predictors of surgical site infection were liver dysfunction, body mass index > 30 kg m−2, and coronary bypass surgery combined with other cardiac procedures. Conclusions Surgical wound infections can be precipitated by multiple factors before, during, and after coronary bypass surgery. Transient liver dysfunction in the perioperative period is associated with an increased rate of surgical infections even after adjusting for known risk factors. Considering this factor as well as other known risks may help to identify and stratify patients with a potentially higher risk of surgical site infections.
