Doctor insights on:
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
Main concern is marfans. Has had a main arterial valve replacement. Metal. Takes all the usual drugs for that. Now has developed fluid on lungs. Treat?
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 moreSee 1 more doctor answer
Can you explain how the heart valves opening/closing is synchronized with the heart's pacemaker firing?
Passive valves: The heart valves are passive mechanisms. They open as blood flows through them. When blood starts to backflow, they slam shut, causing the sounds you hear when you listen to your heart. So long as the valves are functioning properly, the synchronization is all done by the four chambers, with the valves just opening and closing automatically. ...Read moreSee 1 more doctor answer
Monitor/Do nothing: With any medical diagnosis, 'doing nothing' is aka monitoring for a defined time and recheck to see if progression occurred. The risk benefit analysis is in favor of monitoring until serious complication is emminent. With a leaking heart valve, dilated heart chamber, decreased exercise tolerance, are watched with echo. Each case is different, so stay in touch with your cardiac team. Be well. ...Read more
Mechanical valves: Theoretically can last a life time....Porcine on average 10-15 years. ...Read more
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
Depends on problem: Sometimes a valve that doesn't open properly can be helped by opening with a balloon procedure. Sometimes a prosthesis can be passed into the heart via a catheter. Other problems can be fixed by surgically trimming or tightening the valve. In many cases, the best available treatment is to remove the valve and replace it with an artificial valve made from metal, plastic, fabric, or animal tissue. ...Read more
