Aortic Blockage

Aortic blockage, also known as aortic stenosis, is a condition where the aortic valve in the heart becomes narrowed or partially blocked. This narrowing can restrict blood flow from the heart to the rest of the body, causing various health problems. In this article, we’ll explore the types of aortic blockage, its causes, symptoms, diagnostic tests, treatment options, drugs, and surgical procedures in plain and easy-to-understand language.

Types of Aortic Blockage:
