Decoding the volume–outcome relationship in Type A aortic dissection

Over the past few decades, the advents in monitoring, imaging, diagnostics, and implementation of multidisciplinary team approach in Type A aortic dissection surgery resulted in improved surgical outcomes. One other factor that needed to be targeted and carefully analyzed was the volume–outcome relationship on hospital and surgeon level in the settings of Type A dissection. This surely sprung form reports which indicated that supercenters providing aortic services with concentrated expert and expertise were performing better than smaller centers. We dwell in this article on the body of evidence to support concentration of experts and the effect of this organization on volume, referral, and outcome in Type A aortic dissection.
