This study compares clinical performance in a large transaxillary MICS-AVR group to a propensity-matched sternotomy control group. Materials and Methods: This study enrolled 908 patients undergoing isolated AVR with a mean age of 69.4 \u00b1 18.0 years, logistic EuroSCORE of 4.0 \u00b1 3.9%, and body mass index (BMI) of 27.3 \u00b1 6.1 kg\/m2. The treatment group comprised 454 consecutive transaxillary MICS-AVR patients. The control group was 1:1 propensity-matched out of 3115 consecutive sternotomy aortic valve surgeries. Endocarditis, redo, and combined procedures were excluded. The multivariate matching model included age, left ventricular ejection fraction, logistic EuroSCORE, pulmonary hypertension, coronary artery disease, chronic lung disease, and BMI. Results: Propensity-matching was successful with subsequent comparable clinical baselines in both groups. MICS-AVR had longer skin-to-skin time (120.0 \u00b1 31.5 min vs. 114.2 \u00b1 28.7 min; p &lt; 0.001) and more frequent bleeding requiring chest reopening (5.0% vs. 2.4%; p &lt; 0.010), but significantly less packed red blood cell transfusions (0.57 \u00b1 1.6 vs. 0.82 \u00b1 1.6; p = 0.040). In addition, MICS-AVR patients had fewer access site wound abnormalities (1.5% vs. 3.7%; p = 0.038), shorter intensive care unit stays (p &lt; 0.001), shorter ventilation times (p &lt; 0.001), and shorter hospital stays (7.0 \u00b1 5.1 days vs. 11.1 \u00b1 6.5; p &lt; 0.001). No significant differences were observed in stroke &gt; Rankin 2 (0.9% vs. 1.1%; p = 0.791), renal replacement therapy (1.5% vs. 2.4%; p = 0.4762), and hospital mortality (0.9% vs. 1.5%; p = 0.546). Conclusions: Transaxillary MICS-AVR is at least as safe as AVR by sternotomy and can be performed in the same time frame. Its advantages are fewer transfusions and quicker postoperative recovery with a significantly shorter hospital stay. The cosmetic result and unrestricted physical abilities due to the untouched sternum and ribs are unique advantages of transaxillary access.<\/jats:p>","DOI":"10.3390\/medicina59010160","type":"journal-article","created":{"date-parts":[[2023,1,13]],"date-time":"2023-01-13T03:28:10Z","timestamp":1673580490000},"page":"160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Safety and Efficacy of the Transaxillary Access for Minimally Invasive Aortic Valve Surgery"],"prefix":"10.3390","volume":"59","author":[{"given":"Manuel","family":"Wilbring","sequence":"first","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantin","family":"Alexiou","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torsten","family":"Schmidt","sequence":"additional","affiliation":[{"name":"Department of Cardiac Anesthesiology, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6827-2489","authenticated-orcid":false,"given":"Asen","family":"Petrov","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0678-7409","authenticated-orcid":false,"given":"Ali","family":"Taghizadeh-Waghefi","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0284-8200","authenticated-orcid":false,"given":"Efstratios","family":"Charitos","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Kerckhoff Heart Center, 61231 Bad Nauheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Klaus","family":"Matschke","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Arzt","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Utz","family":"Kappert","sequence":"additional","affiliation":[{"name":"Center for Minimally Invasive Cardiac Surgery, University Heart Center Dresden, 01307 Dresden, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,13]]},"reference":[{"key":"ref_1","first-page":"307","article-title":"Aortic Valve Replacement through Right Thoracotomy","volume":"20","author":"Rao","year":"1993","journal-title":"Tex.
