We report our experience for this strategy in our centers.<\/jats:p><jats:p>\n            Methods\u2003Between August 2011 and April 2017, 46 patients (mean age 69\u2009\u00b1\u200911 years, 76% males) received MIMVS-WAC. Indications for this technique were prior coronary bypass surgery (26%), severe or recent left ventricular (LV) dysfunction (30%), or both (39%). The mean EuroSCORE II was 12\u2009\u00b1\u200910.<\/jats:p><jats:p>\n            Results\u2003For each procedure, we conducted right minithoracotomy and hypothermic cardiopulmonary bypass (CPB) after peripheral cannulation. Mean CPB time was 159\u2009\u00b1\u200939 minutes. A mitral valve replacement (MVR) was performed in 23 cases (50%), an annuloplasty in 22 cases (48%), and a prosthesis pannus removal in 1 case (2%). Mean hospital length of stay was 12\u2009\u00b1\u20095.4 days. We report no sternotomy conversions, six reoperations for bleeding, and three deaths at 30 days. Transfusion was requested in 62% (mean infusion 2\u2009\u00b1\u20092.4 packed red blood cells). The postoperative echocardiography showed an LV function preservation in 69% of cases and a reduction of pulmonary arterial pressure in 73% of cases. Four additional deaths occurred in the long-term follow-up (mean 637\u2009\u00b1\u2009381 days, median 593 days). No mitral reoperation was required, with a MR\u2009\u2264\u20092 in 90% of patients.<\/jats:p><jats:p>\n            Conclusion\u2003In high-risk patients, the MIMVS-WAC is a safe technique. It avoids hard dissections while ensuring excellent preservation of cardiac function.<\/jats:p>","DOI":"10.1055\/s-0039-1692403","type":"journal-article","created":{"date-parts":[[2019,6,26]],"date-time":"2019-06-26T22:40:35Z","timestamp":1561588835000},"page":"462-469","source":"Crossref","is-referenced-by-count":2,"title":["Minithoracotomy
