Cardiac Aortic Valve Stenosis

Abstract

Cardiac aortic valve stenosis refers to related clinical symptoms when the aortic valve cannot fully open in the cardiac systolic phase and the blood of the left ventricular cannot fully shoot out; it can be classified into congenital, rheumatic, and senile arteriosclerosis types. With the improvement of people’s living standards and the aging of the population, degenerative aortic valve stenosis has become an important disease influencing the health of senior patients. Its disability rate and fatality rate are even higher among those above 70 years old. Traditional aortic valve replacement is marked by the disadvantages of severe invasion and high blood loss and requires extracorporeal circulation, for which it is intolerable for most senior patients. Catheter-assisted aortic valve replacement is characterized by minimal invasion, fast recovery, and many other advantages and is being more and more frequently used to treat senior patients. The vascular surgery of Changhai Hospital has taken the lead in China to perform transfemoral coronary balloon-expanding aortic valve replacement, having achieved remarkable results. This chapter gives a brief introduction to the clinical manifestations, surgical process, and other details of aortic valve stenosis.
