Abstract:
An acute aortic dissection of the pulmonary autograft with a free rupture of the neoaortic wall is a rare complication after a Ross procedure. In this case, the intimal tear was localized in the noncoronary sinus of the pulmonary autograft and the neoaortic wall was ruptured in the involved sinus area. The dissection was contained in the pulmonary autograft. This report describes a successful aortic root replacement of a patient with the clinical symptoms of an acute aortic type A dissection with a free rupture of the neoaortic wall.

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.
Operant Conditioning
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
