Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Can you tell on an EKG if there is a missing pulmonary valve?

Can you tell on an EKG if there is a missing pulmonary valve?

No: The ECG reflects the electrical activity of the heart. It does not provide images of the heart. The best way to evaluate the pulmonary valve is an echocardiogram. ...Read more

How do they know murmur is innocent if pulmonary valve is not well seen on echo, would doppler show signs even if valve was not seen well?

How do they know murmur is innocent  if  pulmonary valve is not well seen on echo, would doppler show signs even if valve was not seen well?

Typically yes.: Frequently in adults, the pulmonic valve is difficult to see in 2d mode, but spectral and color flow doppler characteristics provide information on the diagnosis and quantification of any pulmonic insufficiency and pulmonic stenosis. ...Read more

What is the function of the pulmonary valve?

What is the function of the pulmonary valve?

Flow direction: Pulmonic valve like all other heart valves, directs the flow from one chamber to another, in this case from the right ventricle to the lungs. It allows the flow to be organized and the timing of flow to be proper. ...Read more

Information/experiences with pulmonary valve replacement risks?

Information/experiences with pulmonary valve replacement risks?

Indication?: Assuming an adult patient, it would be important to determine if replacement is truly necessary. If the valve is very tight and creating right heart failure or low output syndrome (quite rare), valvuloplasty or removal without replacement may suffice. If the valve is infected, other complications may be present. Best left to the attending cardiologist and consulting surgeon. ...Read more

What are recommendations for pulmonary valve stenosis repair in infants?

What are recommendations for pulmonary valve stenosis repair in infants?

Pulmonary stenosis: There are a number of variables that pediatric cardiologists and heart surgeons take into consideration when determining how to approach pulmonary valve stenosis in a neonate. Generally speaking, a catheter-based approach is desirable to avoid surgery, and may be attempted first provided that the anatomy and other patient factors are amenable to that. ...Read more

I have 38 and have to have pulmonary valve replacement. Is it animal or other?

Discuss with MD: You really need to discuss this with your surgeon. It is way too involved of a discussion for this kind of board. ...Read more

What are the postoperative recommendations for pulmonary valve stenosis repair in infants?

What are the postoperative recommendations for pulmonary valve stenosis repair in infants?

Normal: Aswer somewhat depends upon how it was fixed - surgically or catheter - as well as the result. But most ps has a very good outcome and patients have a normal life. Post-op care is quite minimal. ...Read more

What are the advantages and disadvantages of different treatments for absent pulmonary valve?

What are the advantages and disadvantages of different treatments for absent pulmonary valve?

Probably none needed: If born this way, there probably is nothing that absolutely needs to be done because of an absent pulmonic valve per se. The valve adds to efficient function of the "right" (vs. Left) sided heart chambers, but the heart may compensate by itself. Any active intervention may be fraught with more risk than benefit, but consulting a pediatric cardiologist is prudent to confirm this & get best advice. ...Read more

My eight month old daughter was just diagnosed with pulmonary valve stenosis. Can you tell me more about this?

My eight month old daughter was just diagnosed with pulmonary valve stenosis. Can you tell me more about this?

Severity?: It is a congenital defect in which the valve that allows blood to pass out of the right ventricle into the pulmonary artery and lungs doesn't open properly. If mild, it causes no symptoms. If severe, it can strain the right ventricle which eventually will fail. The valve can be stretched open with a catheter (valvuloplasty) or replaced with surgery. ...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


Pulmonary Valve (Definition)

The heart has 4 chambers. The right ventricle is the pumping chamber whic h pushes blood into the lungs so oxygen can be put into the blood. When the right ventricle squeezes, the pulmonary valve opens and blood flows into the lungs. When the right ventricle relaxes to fill, the pulmonary valve closes so blood can't flow backwards ...Read more
