Video Summary
Pulmonary valve disease is a condition that affects the pulmonary valve, which is located between the right ventricle and the pulmonary artery.
Pulmonary valve diseases include pulmonary valve stenosis, which is associated with congenital heart conditions like Tetralogy of Fallot. It results in the pulmonary valve not opening fully and has a characteristic crescendo-decrescendo murmur on auscultation. Over time, it can lead to right-sided heart failure and signs of cyanosis but can be treated with balloon valvuloplasty.
There is also pulmonary valve regurgitation, which results in blood flowing backward into the right ventricle, and it is characterized by a diastolic-decrescendo murmur. It's usually asymptomatic, but over time it can also lead to right-sided heart failure. Pulmonary valve regurgitation can be treated with valve replacement.
