The sign is named after Francesco Cardarelli, an Italian physician who first described it in 1897.
Description
Cardarelli's sign is a physical examination finding in which there is an increased intensity of the second heart sound (S2) heard over the right second intercostal space. This is due to the increased flow of blood through the aorta during diastole, which is characteristic of aortic insufficiency.
