**4.3 Transfusion**

Blood product transfusion is reported to be significantly lower in minimally invasive aortic valve surgery compared to traditional median sternotomy. Reported incidences are from 21.3% to 48.8% [13–18]. The highest reported incidence was by Stolinski et al. in a series of 211 patients who undergone an ART, which is still significantly lower than in the median sternotomy group (67.3%, p < 0.001) [15].
