Cardiac surgery simulation: Step-by-step hemi-Yacoub operation in a preclinical model

We demonstrate a hemi-Yacoub operation on a preclinical model (porcine heart). It is an alternative remodelling technique for the management of dilatation of the ascending aorta with the involvement of the aortic root, particularly the noncoronary sinus or in case of an aortic dissection. The goal of this operation is to replace selectively the dilated/dissected portion (noncoronary sinus), thereby avoiding replacement of the entire aortic root.
