However, aortic valve replacement surgery significantly increases life expectancy. Aortic stenosis (AS) is obstruction of blood flow across the aortic valve due to aortic valve fibrosis and calcification. This makes the heart work harder to pump blood to the restricted opening. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press. The cause of syncope may include ventricular arrhythmias, a sudden decrease in systemic flow caused by the obstruction, or abnormal vasodepressor reflexes caused by the high left ventricular intracavitary pressure.
