Why do the semilunar valves not have chordae tendinae?

Why do the semilunar valves not have chordae tendinae?

Not a good answer: You aren't going to like this: it's the way god made them. It is the intrinsic nature of the semilunar valves that they don't have chordae.(it's like asking, why do we have only 2 arms and not 3?). ...Read more

Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

Is sclerosis of an arterial valve dangerous? I'm 32. I have a RBBB discovered on an EKG. Had an echo showing some sclerosis. something to worry about?

Is sclerosis of an arterial valve dangerous? I'm 32. I have a RBBB discovered on an EKG. Had an echo showing some sclerosis. something to worry about?

Probably not: At this time there is probably nothing to worry about (the cardiologist would have let you know if there was). I would simply adopt a healthy lifestyle of exercise, healthy eating, getting to a normal BMI. As long as the sclerosis doesn't affect the way the heart pumps blood (measured as ejection fraction) then it will not cause problems. RBBB is also pretty common and not dangerous. ...Read more

What is valve disease?

What is valve disease?

Heart valve problems: The heart also has four valves: the tricuspid, pulmonary, mitral, and aortic valves. These valves open and close, acting like doors in the heart, making sure that blood flows correctly from the atria into the ventricles, and then from the ventricles to the rest of the body. Valves can become too leaky, allowing blood to flow backwards, or too narrowed, preventing blood from leaving a chamber. ...Read more
