[Rare variation of hepatic blood supply with accessory right and left hepatic artery].

In recent decades, multiple studies have examined the various manifestations of the hepatic blood supply using anatomical preparation and imaging procedures (angiography, CT). Based on these observations, several classifications have emerged to determine blood supply types and their incidence rates. Our aim is to present a rare variation of the arterial blood supply of the liver through an anatomical preparation.

Real 3D Visualization of the Circumflex Artery Surrounding the Mitral Annulus.

Background:  The circumflex coronary artery is located close to the mitral annulus. Consequently, it is not immune to iatrogenic damage during mitral valve procedures. Our objective was to visualize the circumflex artery from a surgeon's point of view, emphasizing its proximity.
