Abstract:
Aneurysmatic dilatation of the aortic root and ascending portion of the aorta is one of the most complicated pathologies of the cardiovascular system. The 5-year survival rate does not exceed 13%. Especially difficult from the point of view of surgical reconstruction are variants of massive calcification of the aortic root. This article describes a case report concerning the Florida sleeve technique in a patient with diffuse calcification of the aortic root, involving the ostia of the coronary arteries. An important advantage of this type of intervention is technical simplicity consisting in no need for reimplantation of coronary artery ostia, thus decreasing the number of surgical manipulations and sutures on the aortic root, as well as reducing the risk of haemorrhage.

Vector Operations
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.
