Objective The benefits of minimally invasive adult cardiac surgery are well established. Nevertheless, minimally invasive congenital cardiac procedures, even for adult patients, are uncommon. In 2018, we started repairing anomalous aortic origin of a coronary artery (AAOCA) through a 5 cm anterior minithoracotomy when possible to improve cosmesis and avoid sternal precautions. We hypothesized this approach was safe and reliable. Methods A 5 cm incision was made in the right second intercostal space. The incision was carried down to the pericardium while preserving the internal mammary artery. With the pericardium in view, the second and third ribs were disarticulated. Central cardiopulmonary bypass was established, and the repair was carried out based on the patient’s anatomy. The technique was modified to a left anterior minithoracotomy for 1 patient who required pulmonary artery translocation. At any point, if the dissection or repair was not progressing appropriately, the minimally invasive exposure was converted to a partial or traditional median sternotomy. Results Between June 2018 and June 2019, 11 patients underwent minimally invasive anomalous coronary repair. Four patients (3 with body mass index >30) were converted to traditional sternotomy due to poor visualization. Postoperatively, 1 patient required coronary artery bypass after 335 days, due to extensive collaterals and stable angina. Otherwise, at a median follow-up of 437 days (IQR 340 to 480), patients had resumed baseline activity without recurrent symptoms. Conclusions Minimally invasive AAOCA repair may be appealing, although surgeons should be cautious given the high conversion rate.

Objective Robotic-assisted coronary artery bypass is a minimally invasive alternative to traditional coronary artery bypass surgery via median sternotomy with an associated learning curve. The purpose of this study was to investigate the reasons for conversion to sternotomy. Methods From October 2009 to June 2012, two surgeons at one US academic institution performed 271 consecutive robotic-assisted coronary artery bypass procedures. For all cases, isolated, off-pump left internal mammary artery (LIMA) to left anterior descending coronary artery grafting was planned via a 3- to 4-cm sternal-sparing thoracotomy after robotic internal mammary artery harvest and pericardiotomy. Results Conversion to sternotomy occurred in 15 of 271 (5.5%) patients. The most common reason was technical difficulty with the anastomosis, which occurred in 6 (40.0%) patients. Others included LIMA dissection, 2 (13.3%); wrong vessel grafted, 2 (13.3%); ventricular fibrillation and cardiac arrest, 1 (6.7%); equipment malfunction, 1 (6.7%); adhesions, 1 (6.7%); and other. Two underwent emergent conversion. Six underwent multivessel bypass after conversion instead of hybrid coronary revascularization. No mortality occurred among converted patients. Two patients had postoperative myocardial infarction and one had a superficial sternal wound infection. Conversion rate was relatively stable among the four different time quartiles (range, 3.0%–7.4%), although the reasons for conversion were different. Conclusions Conversion to sternotomy is an infrequent complication of robotic-assisted coronary artery bypass, most commonly because of technical difficulties during the LIMA harvest and the LIMA to left anterior descending anastomosis. Anatomic and patient variables as well as inherent technical problems with minimally invasive procedures make conversion unavoidable in some patients.

Abstract Background High-risk patients with multivessel disease (MVD) including a complex stenosis of the left anterior descending coronary may not be ideal candidates for guideline compliant therapy by coronary artery bypass grafting (CABG) regarding invasiveness and perioperative complications. However, they may benefit from minimally invasive direct coronary artery bypass (MIDCAB) grafting and hybrid revascularization (HCR). Methods A logistic European system for cardiac operative risk evaluation score (logES) >10% defined high risk. In high-risk patients with MVD undergoing MIDCAB or HCR, the incidence of major adverse cardiac and cerebrovascular events (MACCEs) after 30 days and during midterm follow-up was evaluated. Results Out of 1,250 patients undergoing MIDCAB at our institution between 1998 and 2015, 78 patients (logES: 18.5%; age, 76.7 ± 8.6 years) met the inclusion criteria. During the first 30 days, mortality and rate of MACCE were 9.0%; early mortality was two-fold overestimated by logES. Complete revascularization as scheduled was finally achieved in 64 patients (82.1%). Median follow-up time reached 3.4 (1.2–6.5) years with a median survival time of 4.7 years. Survival after 1, 3, and 5 years was 77, 62, and 48%. Conclusion In high-risk patients with MVD, MIDCAB is associated with acceptable early outcome which is better than predicted by logES. Taking the high-risk profile into consideration, midterm follow-up showed satisfying results, although scheduled HCR was not realized in a relevant proportion. In selected cases of MVD, MIDCAB presents an acceptable alternative for high-risk patients.

Objectives Minimally invasive CABG is making positive strides in the evolution of coronary artery bypass surgery. We carried out a retrospective study of the efficacy and outcomes of the usage of bilateral internal thoracic arteries in MICS CABG patients over a 6 year period using primary (MACCE) and secondary outcome measures and also carried out a subgroup analysis of patients with diabetes and methodology of revascularization, and with analogy to the SYNTAX trial of the relative risk. Methods Nine hundred and forty patients underwent multivessel MICS CABG via a left mini-thoracotomy from August 2011 to September 2017 and complete revascularization was done using the left internal thoracic artery–right internal thoracic artery Y (LITA–RITA Y) composite conduit. Efficacy and outcomes were evaluated by primary (MACCE) and secondary outcome measures including total length of stay, return to full physical activity, and quality of life. Propensity score matched analyses were carried out in diabetics, in the methodology of revascularization (MICS OPCABG vs. MICS ONCABG), and by comparison to the SYNTAX trial for relative risk. Mean follow-up was 2.9 years (maximum was 5.6 years). Results Out of the 940 patients, 843 (89.6%) were diabetic and 97 (10.4%) were nondiabetic. Average grafts were 3.2. There were 9 mortalities (0.9%). The average ICU and hospital stay was 40 ± 12 hours and 3.1 days. Ten patients (1.06%) required reintervention by angioplasty. A total of 99.3% patients were free from major adverse cardiac and cerebrovascular events (MACCE) at follow-up. Mean follow-up was 33 months and 846 (90%) of the patients were followed up. Based on propensity score–matched groups, patients who had their surgery done by MICS ONCABG (beating heart technique) had greater mean number of grafts and hospital length of stay and had significantly longer ICU stay, extubation in OR and blood loss in comparison to patients who had their CABG done by the MICS OPCABG technique. The new technique has shown favorable risk reduction in comparison to both the arms of the SYNTAX trial. Conclusions The safety, efficacy and outcomes of minimally invasive CABG evaluated by primary (MACCE) and secondary outcomes and quality-of-life measures have been good in this study, especially in diabetics, and have shown results better than conventional CABG. The learning curve can be safely negotiated by using peripheral cardiopulmonary bypass assistance and comparison with the SYNTAX trial has shown a relative reduction in all-cause risk.

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.
