Objective: Cardiopulmonary bypass (CPB) via the right axillary artery (RAA) has become an alternative perfusion strategy, especially in complex aortic procedures. This study delineates our technique and outcome with direct axillary cannulation utilizing the Seldinger technique, which we adopted as the standard perfusion strategy in the sternum-sparing minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) using CPB. Methods: From November 2019 to December 2023, a total of 413 consecutive patients underwent nonemergent isolated coronary artery bypass grafting (CABG) via left anterior minithoracotomy on CPB with peripheral cannulation via the RAA and cardioplegic cardiac arrest, using this technique as a default strategy in the daily routine. All patients had multivessel coronary artery disease. The primary outcome was intraoperative cannulation-related complications (bleeding, revision, ischemia, wound healing complications). The secondary outcome was cannulation-related events during follow-up (blood pressure differences, incidence of brachial plexus injury, clinical signs of circulatory problems of arm and hand, re-interventions). Mean midterm follow-up was 18.7 ± 12.3 [1.1–51.2] months. During follow-up, 16 patients died. Overall, a total of 397 patients (344 male; 67.6 ± 9.7 [32–88]) were included for follow-up (100%). Results: The RAA was successfully cannulated in 100% of patients. A cannula size of 16 Fr was used in 34.6%, 18 Fr in 63.9% and 20 Fr in 1.5% of all patients. There was no intraoperative bleeding complication. In two patients, intraoperative revision of the RAA was required, necessitating a venous patch repair. At follow-up, there were no differences between the systolic and diastolic blood pressure or the pressure gradients between the right and left arm. Transient numbness of the right hand was observed in two patients. Permanent numbness was not observed. No patient needed further intervention or surgical revision of the RAA. Conclusions: The right axillary cannulation is feasible and safe in terms of vascular injury and brachial plexus injury with excellent in-hospital and follow-up outcome.

Background/Objectives: Severe obesity significantly increases the risk of complications following full sternotomy in coronary artery bypass grafting (CABG). However, these patients are frequently excluded from less invasive, sternum-sparing surgical alternatives. This study aimed to assess the safety and practicality of a newly developed technique—Total Coronary Revascularization via left Anterior miniThoracotomy (TCRAT)—that avoids sternotomy in patients with severe obesity requiring multivessel CABG. Methods: From November 2019 to May 2024, a total of 502 non-emergency patients with multivessel coronary artery disease underwent CABG through a left anterior minithoracotomy using cardiopulmonary bypass (CPB) and cardioplegic arrest. Of these, 43 patients with a body mass index (BMI) exceeding 35.0 kg/m² were classified as severely obese and included for subgroup analysis. Their outcomes were compared to those of the remaining 459 patients with BMI below 35.0 kg/m². Key intraoperative variables—such as total operative time, CPB duration, aortic cross-clamp time, and graft strategy—were evaluated. Postoperative outcomes, such as the incidence of major adverse cardiac and cerebrovascular events, minor complications, and length of stay in ICU and hospital, were also analyzed. Results: Severely obese patients exhibited a longer total operation time (353.5 ± 83.6 min vs. 320.4 ± 73.4 min, p < 0.05). In contrast, no statistical differences were observed in aortic cross-clamp time (97.9 ± 27.6 min vs. 95.6 ± 33.0 min; p = 0.307) or CPB time (163.3 ± 35.0 min vs. 155.0 ± 42.9 min; p = 0.078). Both groups received a similar number of distal anastomoses (3.1 ± 0.7 vs. 3.0 ± 0.8; p = 0.194), and the frequency of total arterial revascularization was comparable (34.9% vs. 40.0%; p = 0.268). There were no differences between the groups in major complications, including hospital mortality (2.3% vs. 1.1%, p = 0.227), stroke (0.0% vs. 0.6% p = 0.300), or need for re-revascularization (0.0% vs. 1.1%, p = 0.248). Similarly, minor complications, such as wound healing issues (2.3% vs. 1.1%, p = 0.233) and revisions for bleeding (4.6% vs. 7.2%, p = 0.276), were comparable between groups. ICU stay (2.7 ± 4.5 days vs. 2.2 ± 4.0 days; p = 0.225) and total hospital stay (12.3 ± 9.6 days vs. 10.8 ± 8.6 days; p = 0.142) showed no meaningful differences. Conclusions: TCRAT can be performed safely and effectively in severely obese patients, providing a feasible minimally invasive option for complete coronary revascularization in cases of multivessel disease. This approach eliminates the complications associated with sternotomy, making it a valuable surgical alternative for this high-risk patient group.

Background: A sternum-sparing approach of minimally invasive total coronary revascularization via left anterior thoracotomy (TCRAT) demonstrated favorable early and midterm results in unselected patients with coronary artery multivessel disease. However, safety and outcomes in elderly patients remain less well defined. Particularly in octogenarians with relevant comorbidities, data are scarce, and the role of TCRAT compared to conventional coronary artery bypass grafting (CABG) remains uncertain. This study aimed to evaluate in-hospital and midterm outcomes of TCRAT in patients aged ≥ 80 years. Method: From 11/2019 to 10/2025, CABG via left anterior minithoracotomy on cardiopulmonary bypass and cardioplegic arrest was performed as a routine procedure in 859 consecutive, nonemergency patients. Among them, 82 patients (9.5%) were octogenarians, all presenting with multivessel coronary artery disease. Results: In the group of octogenarians, mean BMI was 26.5 ± 3.1 kg/m², left ventricular ejection fraction was 49.2 ± 9.1% (range 20–55%), and mean EuroSCORE II was 5.1 ± 2.4. Comorbidities included diabetes mellitus (24.4%), chronic lung disease (7.3%), prior PCI (23.2%), and peripheral vascular disease (78.5%). The mean follow-up (100%) was 9.1 months. Left internal thoracic artery was used in 98.8% and radial artery was used in 43.9%. A mean of 3.0 ± 0.9 (range 2–5) anastomoses per patient was performed. Total operation time was 299 ± 64 min (range 164–480). In-hospital mortality was 1.2%, stroke rate was 1.2%, myocardial infarction rate was 0%, and repeat revascularization rate was 1.2%. At follow-up, all-cause mortality, myocardial infarction, repeat revascularization, and stroke were 4.9%, 0%, 2.4%, and 1.2%, respectively. The overall major adverse cardiac and cerebrovascular events rate (MACCE) was 7.3% at follow-up. Conclusion: TCRAT enables complete coronary artery revascularization in multivessel coronary artery disease without sternotomy and can be safely performed in octogenarians. Both in-hospital and midterm outcomes were favorable and comparable to reported contemporary outcomes of conventional CABG in elderly patients.
