Objective Harvesting of the right internal thoracic artery (RITA) under direct vision, through a left minithoracotomy, without robotic or thoracoscopic assistance has never been done or described before. Bilateral internal thoracic arteries (BITAs) in coronary artery bypass grafting (CABG) have shown greater survival and freedom from reintervention. The aim was to develop a multivessel minimally invasive CABG technique in which the BITAs are harvested under direct vision and complete revascularization of the myocardium is done by the off-pump method, using only BITAs (left internal thoracic artery [LITA]–RITAY) through a 2-in left minithoracotomy, without robotic/thoracoscopic assistance—the “Nambiar Technique.” Methods From August 2011 to December 2012, a total of 150 patients underwent off-pump minimally invasive multivessel CABG using BITAs, through a 2-in left minithoracotomy incision. Both internal thoracic arteries were harvested directly under vision, and complete revascularization of the myocardium was done using the LITA-RITAY composite conduit, followed by flow study of the grafts. Coronary artery stabilization for anastomoses was done by using epicardial stabilizers introduced through the minithoracotomy. Results One hundred fifty patients had minimally invasive total arterial myocardial revascularization using BITAs (LITA-RITA Y composite conduit) via a left minithoracotomy. The mean number of grafts was 2.8. A total of 81.6% of the patients had three grafts. Ejection fraction was 34.5 ± 5.2. There was one mortality but no major morbidity. The RITA and LITA harvest times were 39.5 ± 11.2 and 35.2 ± 8.6 minutes, respectively. The total time in the operating room (including extubation) was 331.5 ± 42.5 minutes, and operating time was 240.8 ± 24.6 minutes. One hundred twenty-six patients (87.7%) were extubated on the table. The mean hospital stay was 3.1 days. One patient (0.6%) had an elective conversion to sternotomy because the flow in the LITA-RITA Y composite conduit was inadequate and had saphenous vein grafts. Coronary angiograms were done in 37 patients (25%); and computed tomographic angiograms, in 33 patients (22%), and the grafts were patent. Stress test was done in 80 patients (53%), which had normal findings. Conclusions The Nambiar Technique encompassed using a 2-in left minithoracotomy incision through which the BITAs were conveniently harvested in a skeletonized manner under direct vision without robotic or thoracoscopic assistance. Multivessel total arterial revascularization was then done using the LITA-RITA Y composite conduit by the off-pump methodology. The early outcomes have been excellent, and coronary angiograms showed widely patent grafts. This technique is reproducible and can be done on an empty beating heart to aid in training.

Introduction Although it is not a new technique, minimally invasive direct coronary artery bypass (MIDCAB) is employed only by a few surgeons in the UK. We compared our experience with MIDCAB with that of single vessel off-pump coronary artery bypass (OPCAB) graft surgery through a standard median sternotomy. Methods Patients who underwent either MIDCAB or OPCAB between April 2008 and July 2011 were reviewed. Exclusion criteria included patients with an ejection fraction of <0.5 or previous cardiac surgery. Data were obtained retrospectively from our prospective database, medical records and through general practitioners. Results Overall, 74 patients were analysed in the MIDCAB group and 78 in the OPCAB group. Their demographics and EuroSCORE (European System for Cardiac Operative Risk Evaluation) values were comparable (p>0.05). There was no statistically significant difference in the two groups in terms of mortality, recurrent myocardial infarction, postoperative stroke, wound infection, atrial fibrillation or need for reintervention. The MIDCAB group had six conversions to a sternotomy. Eight patients in each group required blood transfusion, with the average transfusion being 1.8 units in the MIDCAB group and 3.2 units in the OPCAB group. The mean duration of ventilation and intensive care unit stay was 5.0 hours and 38.4 hours in the MIDCAB group and 5.4 and 47.8 hours in the OPCAB group. The mean hospital stay was significantly reduced in the MIDCAB population (6.1 vs 8.5 days, p<0.05). Conclusions MIDCAB can be performed safely in appropriately selected patients with outcomes comparable with OPCAB. The potential benefits include shorter hospital stay, reduced need for blood transfusion and faster recovery.

The OBJECTIVE was to demonstrate perioperative outcomes and angiographic graft patency rates in the mediumterm period in patients after multivessel minimally invasive coronary artery bypass grafting (MICS CABG) procedures.MATERIAL AND METHODS. In the period from 2014 to 2019, 270 patients with stable forms of coronary artery disease were operated on. All patients received left internal thoracic artery (LITA) and venous or arterial (radial artery) grafts. Off-pump surgery was performed in 264 cases (97.8 %). 127 patients underwent CT-bypass angiography (CT-BA) on a 128-slice computed tomography at least after 1 year after the operation. Mean follow-up duration was (30.3±7.9) months.RESULTS. All patients received full myocardial revascularization. Mean number of grafts was (2.6±0.5). Perioperative mortality rate was 0.4 % (1 patient). Perioperative myocardial infarctions or cerebrovascular accident occurred in 3 (1.1 %) and 1 (0.4 %) patients. Overall graft patency rate in examined patients was 89.8 % (290 of 323). At the time of LITA, the patency of mammary grafts was 98.4 % (124 of 126), venous graft –84.0 % (163 of 194) and radial artery grafts – 100 % (3 of 3).CONCLUSION. MICS CABG was safe and effective and was characterized by minimal rate of perioperative complications. This procedure allowed to achieve complete revascularization of the myocardium without sternotomy and could be performed off-pump (in most cases). MICS CABG provide excellent long-term graft patency rates.The authors declare no conflict of interest.The authors confirm that they respect the rights of the people participated in the study, including obtaining informed consent when it is necessary, and the rules of treatment of animals when they are used in the study.

Objective Several reports of awake off-pump coronary artery bypass grafting (AOCAB) under high thoracic epidural anesthesia (TEA) for single-vessel grafts have been published, but few have described its application in multiple bypass procedures. We report the procedures and safety of AOCAB for multivessel disease. Methods Fifty-five multivessel AOCAB (52 men, 3 women; aged 68 ± 9.5 years) were performed at our hospital between 2003 and 2010. A medium sternotomy was made after TEA was established. During coronary artery anastomosis, a stabilizer and an apical suction device were used, and a coronary artery active perfusion system was used to maintain flow distal to the anastomosis. Pneumothorax due to pleural opening, when occurred, was repaired using Neoveil sheet and drainage tube. Results There was no operative death and no cerebral ischemia, cardiac arrhythmia, and chronic obstructive pulmonary disease. Operating time was 177 ± 35 minutes. Left internal thoracic artery was used in 55 anastomoses, right internal thoracic artery in 7, gastroepiploic artery in 17, radial artery in 48, and saphenous vein in 24. Time of anastomosis was 4.93 ± 0.92 minutes for left anterior descending coronary artery, 4.75 ± 1.21 minutes for circumflex artery, and 4.98 ± 1.02 minutes for right coronary artery. Intraprocedural pneumothorax occurred in 17 cases; 14 were repaired and nonintubated AOCAB was accomplished, 1 was intubated, and 2 had temporary assisted ventilation and laryngeal mask. Time to discharge was 15.5 ± 8.4 days. Conclusions Multivessel AOCAB under TEA is not only feasible but also safe. Multiple grafts can be harvested under TEA, and complete vascularization is possible under constant monitoring of blood pressure and consciousness.

The importance of minimally invasive cardiac operations, performed off-pump, without the support of cardiopulmonary bypass (CPB), is continuously increasing. Complete revascularization of obstructed coronary arteries is needed to obtain a better long-term outcome. Insertion into the left ventricle of an efficient microaxial pump can be useful when targeting an important coronary artery located at posterior wall of the heart in a patient with hemodynamic deficiency. The use of such a device can enable surgeons to avoid conversion from a preplanned off-pump strategy to traditional on-pump coronary bypass surgery. The Impella Microaxial Ventricular Assist Device (VAD) (Abiomed, Aachen, Germany) is a miniature pump with a 7-mm catheter and a flow rate of approximately 2.5-5 L/min. This device can enable cardiovascular surgery to be performed without damaging the left ventricle and causing serious aortic deficiency. Therefore, in patients with serious comorbidity, complete revascularization may be performed off pump, with the heart beating, because of the hemodynamic stability provided with the support of the microaxial intracardiac pump. If required, this pump can also support the heart during the early postoperative period. We report the first assisted beating-heart coronary artery bypass graft surgery performed with the Impella Microaxial VAD in our country. The surgery was performed on 2 patients considered high risk on the basis of EUROSCORE testing.

Introduction Multivessel coronary artery bypass graft (CABG) with bilateral internal thoracic arteries (BITA) has only been uncommon and technically demanding. We describe our experience with BITA only CABGs requiring ≥ 4 anastomoses. Material and Methods The department's database was queried for patients undergoing isolated CABG with ≥ 4 anastomoses. The surgical technique included systematically a right internal thoracic artery (ITA) of left ITA Y graft. The multivariate model included variables with a p < 0.3 at univariate analysis. Results Between January 2006 and December 2009, 251 consecutive patients (71 ± 10 years) (on-pump: 130, off-pump: 121) had CABG with ≥ 4 anastomoses, representing 21% of total isolated CABGs for the same period; all patients received a totally arterial BITA only revascularization. Follow-up was 4.9 ± 1.6 years. Overall and cardiac cumulative survivals were 78 and 92%, respectively, at 5 years. The occurrence of any major postoperative complication was associated with overall and cardiac mortality (odds ratio [OR]: 3.6, 95% confidence interval [CI]: 1.3–9.9 and OR: 5.4, 95% CI: 1.3–21.9, respectively). Major sternal wound complication requiring surgical revision was not associated with impaired glucose control (n = 9; diabetics: 6/82, 7.3%; nondiabetics: 3/169, 1.8%, p = 0.06). Preoperative kidney failure was associated with incomplete revascularization (OR: 6.2; 95% CI: 1.2–33.5), that was unfailingly due to ungraftable right coronary artery targets. Discussion BITA only revascularization was a valuable and safe procedure, with favorable results in terms of morbidity and mortality at a 5 years' follow-up.

Background Clinical outcomes (as national clinical data) of isolated coronary artery bypass grafting have been successively reported, based on data registered in the Japan Cardiovascular Surgery Database, since 2013. In this study, we analysed the clinical results of isolated coronary artery bypass from 2017 to 2018 as a biannual report. Methods Data from the Japan Cardiovascular Surgery Database on isolated coronary artery bypass performed in 2017 and 2018 were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery. Results Isolated off-pump coronary artery bypass was performed in 54.6% ( n = 14,684) of all coronary artery bypass cases ( n = 26,913), and graft material for the left anterior descending artery was the left internal thoracic artery in 76.4% of cases and the right internal thoracic artery in 19.0% of cases. Operative mortality was 1.5% in elective cases (on-pump coronary artery bypass 1.9% and off-pump 1.2%, p < 0.001), 7.4% in emergency cases (on-pump 10.2% and off-pump 4.3%, p < 0.001), and 2.5% overall. Postoperative morbidity was generally lower in off-pump coronary artery bypass. The severity of surgery with expected mortality, evaluated using JapanSCORE II, is increasing every year. Conclusions Our findings suggest that short-term operative results for isolated coronary artery bypass are stable, and operative candidates are shifting to higher-risk patients.

Abstract Background Perioperative hypothermia is not uncommon in surgical patients due to anesthetic-induced inhibition of thermoregulatory mechanisms and exposure of patients to cold environment in the operating rooms. Core temperature reduction up to 35°C is often seen in off-pump coronary artery bypass graft (OP-CABG) surgery. Anesthetic depth can be monitored by using bispectral (BIS) index. The present study was performed to evaluate the influence of mild hypothermia on the anesthetic depth using BIS monitoring and correlation of BIS with end-tidal anesthetic concentration at varying temperatures during OP-CABG. Materials and Methods In a prospective observational study design in a tertiary care teaching hospital, patients who underwent elective OP-CABG under endotracheal general anesthesia, were included in the study. Standard technique of anesthesia was followed. BIS, nasopharyngeal temperature, and end-tidal anesthetic concentration of inhaled isoflurane was recorded every 10 minutes. The BIS was adjusted to between 45 and 50 during surgery. Results There were 40 patients who underwent OP-CABG during the study period. The mean age was 51.2 ± 8.7 years, mean body mass index 29.8 ± 2.2, and mean left ventricular ejection fraction was 55.4 ± 4.2%. Anesthetic requirement as guided by BIS between 45 and 50 correlated linearly with core body temperature (r = 0.999; p < 0.001). The mean decrease in the body temperature at the end of 300 minutes was 2.2°C with a mean decrease in end-tidal anesthetic concentration of 0.29%. The reduction in end-tidal anesthetic concentration per degree decrease in temperature was 0.13%. None of the patients reported intraoperative recall. Conclusion In this study, BIS monitoring was used to guide the delivery concentration of inhaled anesthetic using a targeted range of 45 to 50. BIS monitoring allowed the appropriate reduction of anesthetic dosing requirements in patients undergoing OP-CABG without risk of awareness. There was a significant reduction in anesthetic requirements associated with reduction of core temperature. The routine use of BIS is recommended in OP-CABG to titrate anesthetic requirement during occurrence of hypothermia and facilitate fast-track anesthesia in this patient population.
