What is a healthy heart rate?
A healthy heart moves blood efficiently from chamber to chamber and then out to the rest of the body. A cascade of electrical signals carried by nerves synchronizes the cycle. These signals provide the regular pace for the heart, normally 60 to 100 beats per minute.
What is sudden heart failure?
Sudden heart failure is an emergency medical situation and requires immediate care. Sudden heart failure causes rapid fluid buildup, or congestion, in the lungs and other parts of the body. It occurs when the heart does not pump as much blood as the body needs. Symptoms develop suddenly and include:
- Severe shortness of breath.
- An irregular or rapid heartbeat.
- Coughing up foamy, pink mucus.

What are the two types of aortic valve prostheses?
Johns Hopkins Medicine answered
There are two major types of aortic valve prostheses - mechanical and tissue.
Mechanical replacement valves have lifelong durability, however a blood thinning drug must be taken for the rest of the patient's life to prevent blood clots from forming on the hinges of the valve. Besides being somewhat of a nuisance, taking blood thinners also create a small risk of bleeding complications.
Tissue or "bioprosthetic" valves are made of cow or pig tissue. Because they are made of natural materials, there isn't a need to take blood thinners. However they are less durable, lasting about 10-15 years.
Your doctor will help you make a decision on which kind of aortic valve replacement to pick based on your age, occupation, lifestyle, medical history, and preference.
