Pulmonary valve insufficiency or regurgitation is the valvulopathy characterized by the presence of diastolic retrograde flow from the pulmonary artery to the right ventricle. If severe, this regurgitation leads, in time, to the appearance of right ventricular dysfunction and heart failure. This condition can be primary (congenital- as a stand alone disease or in association with Marfan syndrome), caused by endocarditis, rheumatic or carcinoid heart disease or secondary to pulmonary hypertension, percutaneous or surgical dilatation of a pulmonary stenosis or dilated cardiomyopathy.
Pulmonary valve insufficiency patients are asymptomatic if disease severity is mild. However, one-third of them will become symptomatic before reaching the age of forty years . Severe regurgitation leads to symptoms of right heart failure  like dyspnea, initially with physical effort and later at rest ; fatiguability, abdominal distention due to ascites, liver distention causing pain in the right hypochondrium, early satiety and peripheral edema. Non-specific signs include angina due to the inability of the coronary arteries to properly oxygenate a dilated right ventricle, palpitations caused by atrial  or ventricular arrhythmias, that have a potential to be life threatening  and syncope- an insufficient, dilated heart will not provide proper cerebral blood flow. Symptoms associated with the underlying disease causing secondary pulmonic regurgitation may also be encountered: fever in infective endocarditis, hemoptysis in pulmonary hypertension or articular symptoms in rheumatic heart disease. Furthermore, acute neonatal pulmonary valve insufficiency caused by a large patent ductus arteriosus in Ebstein's anomaly patients has also been described .
Physical examination reveals an accentuated and delayed pulmonary component of the second heart sound if pulmonary hypertension is present. The pulmonary insufficiency murmur is brief, early diastolic and decrescendo and increases with squatting and inspiration. Valsalva maneuver decreases its intensity. If pulmonary hypertension coexists, the murmur modifies its character by becoming high pitched and possibly holo- diastolic. A tricuspid regurgitation murmur may overlap, making auscultation more difficult. If the right ventricle is enlarged, an impulse may be palpated along the left sternal border. Signs of elevated jugular venous pressure signs may also be observed.

Overview Pulmonary valve stenosis is a condition in which a deformity on or near your pulmonary valve narrows the pulmonary valve opening and slows the blood flow. [mayoclinic.org]
Areas of potential narrowing include thickened muscle below the pulmonary valve, stenosis of the valve itself, or stenosis of the pulmonary artery above the valve. [cincinnatichildrens.org]
What is pulmonary valve stenosis? Pulmonary valve stenosis is the term describing a narrowing in the opening of the pulmonary valve. [childrenshospital.org]

Heart Valve Diseases Also called: Valvular heart disease Your heart has four valves. Normally, these valves open to let blood flow through or out of your heart, and then shut to keep it from flowing backward. But sometimes they don't work properly. [icdlist.com]
Symptoms associated with the underlying disease causing secondary pulmonic regurgitation may also be encountered: fever in infective endocarditis, hemoptysis in pulmonary hypertension or articular symptoms in rheumatic heart disease. [symptoma.com]
- Heart Murmur
The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. [icdlist.com]

Thoracic radiography is useful especially in pulmonary hypertension patients, where the typical aspect of enlarged central pulmonary and hilar vessels and diminished peripheral vascularization is observed. Cardiomegaly may also be present.
The electrocardiogram may show right ventricular hypertrophy (tall R or QR aspect in V1, negative T wave in V1-V3 and right axis deviation) or dilatation (complete or incomplete right bundle branch block and right axis deviation) and right atrial enlargement.
Echocardiography further characterizes chamber dimensions, wall thickness, and kinetics, as well as the aspect of the pulmonary valve, that may be dilated, perforated, ruptured or have attached vegetations. An immobile or abnormal motion of the interventricular septum is an indirect indicator of pulmonary hypertension and increased right ventricular pressures. Color flow Doppler offers a qualitative assessment of the regurgitant pulmonary jet in terms of dimensions and orientation. If regurgitation is holodiastolic or pulmonary acceleration time (normally 140 msec) is decreased, pulmonary hypertension must be suspected and demonstrated by calculating pulmonary artery systolic and diastolic pressures, both good predictors of cardiac status  . Vena contracta has not yet been validated for pulmonary regurgitation. Regurgitant volume and regurgitant fraction can be calculated using pulsed Doppler  and stroke volume.
Pulmonary artery angiography is indicated when pulmonary embolism as a cause of pulmonary hypertension and pulmonary valve insufficiency is suspected. The same information can be obtained with less invasive methods, such as computer tomography angiography or ventilation/perfusion scanning, while cardiac magnetic resonance imaging offers high quality characterization of pulmonary valve anatomy and regurgitation mechanism.
Treatment On its own, pulmonary valve insufficiency is seldom severe enough to require treatment. Antibiotics are usually recommended before dental work to reduce the possibility of bacterial endocarditis. [medical-dictionary.thefreedictionary.com]
The newest types of pulmonary valve insufficiency treatment include pulmonary homograft and the Melody valve treatment. A pulmonary homograft is usually used for the treatment of children, because it can adapt to the body as the child grows. [bookinghealth.com]
