Background Median sternotomy is the gold standard incision for most cardiac operations. However, with the advent of minimal invasive surgery, a new approach emerged in cardiac surgery named mini-sternotomy and has been successfully used to perform a variety of operations.  The aim of this paper is to present our experience of using mini-sternotomy to harvest the left internal mammary artery (LIMA) for off-pump revascularization of the left anterior descending artery (LAD)  Methodology Over a 2-year period (October 2012-October 2014), 100 patients underwent coronary artery bypass grafting (CABG) via conventional median sternotomy (CMS) (n=80) and mini-sternotomy (MS) (n=20). The 2 groups were compared regarding length and difficulty of surgery, postoperative pain and respiratory function, stay in the intensive care unit (ICU), wound infection, shoulder stability and other variables.  Results One patient (5%) with LMS was converted into CMS due to inadequate exposure. The blood loss was less in LMS patients. Lung atelectasis and pleural effusions were less in group 2. A higher PaO2, lower PaCO2 and a shorter assisted-ventilation time were observed in LMS group. Early postoperative pain score & analgesic requirements were less in LMS patients and their hospital stay was shorter (4-5 days) than CMS. Moreover, LMS patients could return to their jobs and drove cars earlier than group 2 patients. There were 9 deaths (11.3%) in CMS group vs. one death (5%) in LMS group; however, this difference was not statistically significant (p˂0.05)  Conclusions This study shows that off-pump coronary surgery through mini-sternotomy incision is feasible and safe.

Introduction: We describe how to perform left internal mammary artery (LIMA) bypass to the left anterior descending (LAD) artery, the so-called MINI Off-pump Coronary Artery Bypass (MINI OPCAB). Materials and Methods: We included patients with a demonstrated predominant ischemia related to the LAD territory. Of 70 patients who were operated upon at the Benetti Foundation, 10 received hybrid revascularization. Surgical Technique: The patient is prepared as for a standard coronary bypass operation through sternotomy. The sternum is opened to the 3rd or 4th intercostal space depending on the anatomy, and a retractor is put in place. The left mammary artery is generally dissected to about 8 cm and isolated without the veins. Importantly, the angle of the superior part, where the mammary artery is attached to the sternum, needs to be below 20% to avoid any potential kinking. The pericardium is cleaned to identify the area of the pulmonary artery. The pericardium is opened to the apex and towards the right to around 5 to 6 cm initially. In most cases, the area of the LAD can be seen and the potential area of the anastomosis is defined. The patient is heparinized and the LAD is occluded with 5-0 Proline. A mechanical stabilizer is put in place and the anastomosis is performed. When the bypass is finished, and before sutures are tied, the stitches of 5-0 polypropylene around the artery are released, along with the clamp of the mammary artery; the anastomosis is then tied. The mechanical stabilizer is removed, the stitches of the pericardium are released and the flow of the graft is measured, while ensuring that there is no kinking. If the flow and Pulsatility and Resistance (PR) are acceptable, the mammary is fixed with 2 stitches of 7-0 polypropylene on both sides around 1 cm from the anastomosis. The heparin is reverted with protamine and a drain is put in place, while taking care to avoid any chance of touching the mammary artery or the anastomosis. The sternum is closed with 1 or 2 wires. Results: Operative mortality in this series was 0%; one patient was converted to sternotomy off-pump (1.4%). None of the grafts were revised after measurement with a Medistim system (Medistim ASA, Oslo, Norway). Fifty five patients (79%) were extubated in the operating room The average hospitalization stay was 60 hours (SD 17, 95% CI). Sixteen patients who underwent the LIMA-to-LAD procedure were restudied, with 100% patency. At 144 months, 82% of the patients were alive and 68% were asymptomatic. Conclusion: Additional clinical experience is required to be able to reproduce this operation on a large scale and expand the MINI OPCAB operation in hybrid revascularization.

Objective At present, minimal invasive direct coronary artery grafting is the least invasive nonrobotic surgical approach to revascularize the left anterior descending artery with the left internal mammary artery. Total endoscopic coronary bypass grafting is performed with the help of a telemanipulator (“robot”). A prospective proof-of-concept study was initiated to investigate a nonrobotic total endoscopic coronary bypass grafting approach. Methods Twenty patients with significant left anterior descending artery or left main stem lesion were operated on via three or four left thoracic access ports. Under exclusive endoscopic vision, the left internal mammary artery was harvested and anastomosed to the left anterior descending artery manually. Cardiopulmonary bypass and cardioplegic arrest were planned in all cases. Results In 10 patients, the operation was completed successfully as nonrobotic total endoscopic coronary bypass grafting. Reasons for conversions to minimal invasive direct coronary artery grafting or conventional sternotomy were dense pleural adhesions (3 patients), bleeding of the anastomosis (3), diffuse bleeding during left internal mammary artery harvesting (2), identification problems of the target artery (1), or left internal mammary artery failure (1). Postoperative angiography in five primarily successful nonrobotic total endoscopic coronary bypass grafting patients showed patent anastomoses in four cases. One patient was reoperated on for early anastomotic failure in a 1.0-mm target vessel. Until now, a percutaneous coronary intervention of remaining lesions as staged hybrid procedure was performed in three patients (2 nonrobotic total endoscopic coronary bypass grafting, 1 minimal invasive direct coronary artery grafting). Conclusions With a thoroughly surveyed learning curve, nonrobotic total endoscopic coronary bypass grafting procedure could become an alternative to other available treatment options; however, the value of the procedure has to be further investigated.

Objective Hybrid coronary revascularization is offered as an alternative strategy for patients with multivessel coronary artery disease (CAD). We present our experience and provide a comparative analysis to off-pump coronary artery bypass grafting (OPCAB). Methods Ninety-one patients with multivessel CAD underwent minimally invasive left internal mammary artery to left anterior descending grafting in combination with percutaneous coronary intervention of nonleft anterior descending targets (HYBRID). The primary end point of this study was major adverse cardiac and cerebrovascular events (MACCE), defined as death, stroke, and nonfatal myocardial infarction. MACCE in the HYBRID group were compared with 4175 contemporaneously performed OPCAB operations by logistic (30-day outcomes) and Cox proportional hazards (long-term survival) regression methods. Propensity scoring was used to adjust for potential selection bias. Results The 30-day MACCE (death/stroke/nonfatal myocardial infarction) rate was 1.1% for the HYBRID group (0%/0%/1.1%) and 3.0% for the OPCAB group (1.8%/1.1%/0.5%) (odds ratio = 0.47, P = 0.48). Angiographic left internal mammary artery evaluation was obtained in 95.6% of patients (87 of 91) revealing FitzGibbon A patency in 98.0% (96 of 98). The reintervention rate at 1 year for the HYBRID group was 5.5% (5 of 91) and was limited to repeat percutaneous coronary intervention. Three-year survival was statistically similar for the two groups (hazard ratio = 0.44, P = 0.18, see Kaplan-Meier figure). Conclusions Hybrid coronary revascularization may be noninferior to OPCAB with respect to early MACCE and 3-year survival in the treatment of multivessel CAD.

Background: Conventional coronary artery bypass surgery (CABG) is associated with substantial morbidity caused by cardiopulmonary bypass (CPB) and median sternotomy. Here we described an innovative technique to perform complete revascularization through a left lateral thoracotomy without CPB (ThoraCAB). Methods: From September 2005 to December 2008 a total 83 patients underwent ThoraCAB in National Institute of Cardio Vascular Diseases (NICVD). The patient is positioned with the left side elevated to 45 degree. A 6 to 8 inches long incision is made over the left 4th or 5th intercostal space from just medial to the nipple to the anterior axillary line. The left internal mammary artery (LIMA) is harvested as a pedicle graft under vision. Distal coronary anastomosis is completed first on the beating heart using a stabilizer, followed by proximal anastomoses on the descending aorta. Peroperative and postoperative complication the arrhythmia hypotension wound infection death was observed. Results: Complete revascularization was achieved in all patients. The number of grafts averaged 2.18±1.08 per patients. One patient died (1.2%) due to severe respiratory acidosis. One patient (1.2%) was converted to CPB due to arrhythmia. No strokes were observed. Of these patients, 7.2% developed new onset postoperative atrial fibrillation. Conclusion: ThoraCAB has been feasible in the vast majority of the patients requiring CABG surgery. The prevalence of the post operative atrial fibrillation was low. Left lateral thoracotomy offers an attractive and effective alteration to Off Pump median sternotomy.

We present the case of a 72-year-old man who underwent off-pump coronary artery bypass grafting of 4 coronary arteries with exclusive use of the left internal mammary artery with a side-branch (mediastinal artery). Before discharge from the hospital, contrast computed tomography angiography confirmed the patency of all 4 coronary grafts. Use of the mediastinal artery side-branch of the internal mammary artery allowed grafting of 4 coronary arteries using only one internal thoracic artery.

A 62-year-old man with a prior history of Coronary Artery Bypass Grafting (CABG) presented in cardiogenic shock. A percutaneous left femoral Impella CP® Left Ventricular Assist Device (LVAD) was placed with modest improvement in hemodynamics. The LVAD was upgraded to an open right transaxillary Impella 5.0® with hemodynamic stabilization. Cardiacfunction was assessed with serial echocardiography demonstrating persistent severe left ventricular dysfunction. In view of previous CABG with patent Left Internal Mammary Artery (LIMA) graft the decision was made to place a HeartMate 3® LVAD via left thoracotomy with LV apical inflow and descending aortic outflow. This approach was completed without the need for Cardiopulmonary Bypass (CPB). The postoperative course was uneventful and discharge to a rehabilitation center occurred on the ninth postoperative day.
