Minimally invasive MV surgery (MIMVS) is increasingly adopted worldwide, with a potential benefit in the elderly. This study compares short-term and mid-term outcomes in patients above 70 years, undergoing MIMVS versus median sternotomy (MST), in a nationwide registry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>All patients above 70 years undergoing primary elective MV surgery (\u00b1tricuspid valve [TV] surgery, atrial septal defect closure, rhythm surgery) between 2013 and 2021 were included.

No statistically significant differences in baseline characteristics were found. Median Logistic EuroSCORE I was 6.3 [4.7\u20138.5] vs 6.0 [4.6\u20138.5], P\u2009=\u2009.27 for MST and MIMVS, respectively. Mitral valve repair (77.7% vs 64.7% P\u2009&amp;lt;\u2009.001) and concomitant TV surgery (43.9% vs 18.2%, P\u2009&amp;lt;\u2009.001) was more frequently performed in MST. Lower 30-day mortality was observed in MIMVS (0.6% [n\u2009=\u20094] vs 2.5% [n\u2009=\u200921], P\u2009=\u2009.01). Furthermore, the incidence of pneumonia, prolonged intubation, readmission to intensive care unit, kidney failure, and new-onset arrhythmia were lower for MIMVS. No difference in 5-year survival was found (MST: 89.1\u2009\u00b1\u20094.6% vs MIMVS: 91.6\u2009\u00b1\u20094.7% Log-Rank P\u2009=\u2009.51).<\/jats:p>\n                  <\/jats:sec>\n
