The most common minimally invasive approach for aortic valve replacement (AVR) is the partial upper mini-sternotomy. The aim of this study is to understand which preoperative computed tomography (CT) features are predictive of longer operations in terms of cardio-pulmonary bypass timesand cross-clamp times. Methods. From 2011 to 2022, we retrospectively selected 246 patients which underwent isolated AVR and had a preoperative ECG-gated CT scan. On these patients, we analysed the baseline anthropometric characteristics and the following CT scan parameters: aortic annular dimensions, valve calcium score, ascending aorta length, ascending aorta inclination and aorta\u2013sternum distance. Results. We identified augmented body surface area (&gt;1.9 m2), augmented annular diameter (&gt;23 mm), high calcium score (&gt;2500 Agatson score) and increased aorta\u2013sternum distance (&gt;30 mm) as independent predictors of elongated operation times (more than two-fold). Conclusions. Identifying the preoperative predictive factors of longer operations can help surgeons select cases suitable for minimally invasive approaches, especially in a teaching context.<\/jats:p>","DOI":"10.3390\/jcm12216717","type":"journal-article","created":{"date-parts":[[2023,10,24]],"date-time":"2023-10-24T11:39:04Z","timestamp":1698147544000},"page":"6717","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Aortic Valve Replacement: Understanding Predictors for the Optimal Ministernotomy Approach"],"prefix":"10.3390","volume":"12","author":[{"given":"Francesco Giosu\u00e8","family":"Irace","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1354-9599","authenticated-orcid":false,"given":"Ilaria","family":"Chirichilli","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Russo","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Federico","family":"Ranocchi","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcello","family":"Bergonzini","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Lio","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Nicol\u00f2","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Musumeci","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery and Heart Transplantation, San Camillo Forlanini Hospital, Viale Gianicolense 87, 00151 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2492","DOI":"10.1016\/j.jacc.2020.09.595","article-title":"STS-ACC TVT registry of transcatheter aortic valve replacement","volume":"76","author":"Carroll","year":"2020","journal-title":"J.
