Pulmonary valve

Anatomy The pulmonary orifice lies nearly in the horizontal plane, and is situated at a more superior level than the aortic orifice.

• Electrocardiogram (EKG): An EKG might indicate heart enlargement due to the pulmonary regurgitation, allowing blood to backflow into the right ventricle. • Echocardiogram: An echocardiogram is an ultrasound of the heart, which can show malfunction of the pulmonary valve and right ventricle enlargement. • Angiography: A healthcare provider, usually a cardiologist, injects contrast into a catheter fed into the heart to assess the function of the pulmonary valve. • Cardiac magnetic resonance: This imaging test can determine the severity of the pulmonary regurgitation and the dilation (opening) in the pulmonary artery from the increased pressures. Prognosis Prognosis depends on the severity of the pulmonary regurgitation. For mild to moderate pulmonary regurgitation, there is no significant impact to survival rates. In severe pulmonary regurgitation, there tends to be increased strain on the right ventricle, which causes abnormal heart rhythms and right ventricle failure. Severe complications can lead to an increased risk of cardiac death. A Word From Verywell A diagnosis of a heart condition can be overwhelming and scary. Being informed about pulmonary regurgitation, including available treatment options, can help you feel confident in developing an effective treatment plan with your healthcare provider. The goal is to ensure that you are well-informed and able to live the healthiest life possible.

Lung valves, also known as endobronchial valves (EBV), are a relatively new treatment for people with severe emphysema. Emphysema is a lung condition that falls under the umbrella of chronic obstructive pulmonary disease (COPD). Emphysema happens due to the destruction of tiny air sacs in the lungs called alveoli. This greatly affects the exchange of vital oxygen and carbon dioxide in the lungs. Continue reading to learn more about lung valves, how they work for emphysema, and who is a good candidate for this treatment. With Lung valves are medical devices that are implanted into the most damaged areas of the Lung valves help control the flow of air in lungs that have been damaged by emphysema. They prevent air from entering the most damaged areas while allowing air that’s become trapped in these areas to escape. A procedure called endobronchial valve placement involves collapsing the most damaged areas of the lung with the placement of one-way valves. By doing this, it makes it easier for the diaphragm and chest wall to move as they should. Basically, by not having big, damaged areas of the lung getting in the way of breathing, it allows more space in the chest for healthier parts of the lung to work. This can make it easier for people with emphysema to breathe. This is a reversible procedure and has a similar effect as surgically removing the damaged part of the lung, but it’s a less invasive procedure. Lung valves were first approved by the One of the potential treatmen...

The Zephyr valve is a device that can improve breathing in people with emphysema, one of the two most common types of chronic obstructive pulmonary disease (COPD). The valve received Results from • increase lung function • reduce shortness of breath • improve quality of life But the procedure comes with some risks and requires a multiple-day hospital stay. Still, it may hold great promise for those with COPD, specifically severe emphysema, who are looking for new treatments. A Zephyr valve is a device to Emphysema causes the air sacs in your lungs to lose their elasticity. When you breathe, air gets trapped in these sacs and doesn’t escape when you exhale. Over time, these parts of your lungs become overinflated. This puts pressure on the healthy parts of your lungs, making it harder to breathe. A Zephyr valve is a one-way valve doctors place in your airway. It allows trapped air to escape but prevents new air from entering the damaged part of your lung. • Almost half (47.7%) of participants who received the valves had a 15% or greater increase in lung function. • Participants who received the valves had increased exercise capacity, measured in their ability to walk farther. • Those who received valves also had less shortness of breath during day-to-day activities. The Zephyr valve is for people ages A doctor will also need to test if you have collateral ventilation in the lobes of your lungs. This means that air from one lobe of your lung can move into another lobe. Zephy...

Chambers and valves of the heart A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. Pulmonary valve repair and pulmonary valve replacement are procedures to treat a diseased or damaged pulmonary valve. The pulmonary valve is one of four valves that control blood flow in the heart. It's between the lower right heart chamber (right ventricle) and the artery that delivers blood to the lungs (pulmonary artery). Pulmonary valve regurgitation In pulmonary valve regurgitation, a leaky valve allows blood to flow backward into the heart rather than directly to the lungs for oxygen. Pulmonary valve repair and pulmonary valve replacement are done to treat pulmonary valve disease. Pulmonary valve disease is a condition in which the lung (pulmonary) valve doesn't work properly. It may occur on its own or with other heart conditions present at birth (congenital heart defects), such as tetralogy of Fallot. Types of pulmonary valve disease that may require treatment with pulmonary valve repair or pulmonary valve replacement include: • Pulmonary valve regurgitation. A leaky pulmonary valve allows blood to flow backward into the heart (pulmonary valve regurgitation) rather than directly to the lungs for oxygen. • Pulmonary val...

What is pulmonary regurgitation? Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the right ventricle to the lungs. A leaky pulmonary valve allows blood to flow back into the heart chamber before it gets to the lungs for oxygen. What causes pulmonary regurgitation? The most common causes for a leaky pulmonary valve is Less common causes are: • • Complications after surgery to repair • Carcinoid syndrome • (link opens in new window) and complications after catheterization (rare causes in the United States) What are the symptoms of pulmonary regurgitation? There are usually no noticeable early symptoms. Signs that can be detected during a medical exam include a Eventually, the right ventricle can become enlarged. Rarely, these conditions can progress to How is pulmonary regurgitation treated? Jen was born with tetralogy of Fallot, and ultimately had valve replacement surgery for her pulmonary valve. Watch Jen share her story:

Overview Pulmonary valve disease affects the valve between the heart's lower right chamber and the artery that delivers blood to the lungs. That artery is called the pulmonary artery. The valve is called the pulmonary valve. A diseased pulmonary valve doesn't work properly. Pulmonary valve disease changes how blood flows from the heart to the lungs. The pulmonary valve usually acts like a one-way door from the lower right heart chamber to the lungs. Blood flows from the chamber through the pulmonary valve. It then goes to the pulmonary artery and into the lungs. Blood picks up oxygen in the lungs to take to the body. Types of pulmonary valve disease include: • • Pulmonary valve regurgitation. The flaps of the pulmonary valve don't close tightly. Blood moves backward into the right lower heart chamber, called the right ventricle. • Many types of pulmonary valve disease are due to heart conditions present at birth. Treatment depends on the type and severity of pulmonary valve disease. • Heart valve disease. National Heart, Lung, and Blood Institute. http://www.nhlbi.nih.gov/health/health-topics/topics/hvd.
