What is Pulmonary valve stenosis also called?
I guess you refer to the pulmonary valve stenosis which usually is due to the valve calcification when less blood supply will go from right ventricle of heart to the pulmonary circulation. The right ventricle will be hypertrophied because it's working harder then before.
What is the cause of pulmonary stenosis?
Pulmonary stenosis is almost entirely congenital.
Is Pulmonary stenosis congenital?
Yes
How is Pulmonary valve stenosis prevented?
Pulmonary valve stenosis cannot be prevented
What is pulmonary stenosis also called?
Pulmonary valve stenosis
Is pulmonary stenosis dangerous?
Pulmonary stenosis can be life-threatening
Does pulmonary valve stenosis kill infants?
Patients with the most severe form of pulmonary valve stenosis may die in infancy
How does diagnosis of pulmonary valve stenosis begin?
Diagnosis of pulmonary valve stenosis begins with the patient's medical history and a physical exam. Tests to confirm the diagnosis include chest x ray, echocardiogram, electrocardiogram, and catherization
How is Pulmonary stenosis prevented?
Pulmonary stenosis cannot be prevented
What are the causes of aortic valve stenosis?
Aortic valve stenosis can occur because of a birth defect in the formation of the valve. Calcium deposits may form on the valve with aging, causing the valve to become stiff and narrow. Stenosis can also occur as a result of rheumatic fever.
What is aortic valve stenosis?
A stenosed valve is a valve that has been narrowed for some reason; either by injury, scar tissue or congenital anomaly. Depending on the level of stenosis, cardiac output can be fixed (unable to be changed) and reduced.
Pulmonary valve stenosis?
DefinitionPulmonary valve stenosis is a condition in which the flow of blood from the heart (right ventricle, or lower chamber) is blocked at the valve that separates the heart from the pulmonary artery (pulmonic valve). This narrowing is usually present at birth (congenital).Alternative NamesValvular pulmonary stenosis; Heart valve pulmonary stenosisCauses, incidence, and risk factorsPulmonary valve stenosis is most often caused by a problem that occurs when the unborn baby (fetus) is developing. The cause is unknown, but genetics may play a role.Narrowing that occurs in the pulmonary valve is called pulmonary valve stenosis. Narrowing that occurs below the pulmonary valve is called subvalvar pulmonary stenosis. Another form of the condition, supravalvar pulmonary stenosis, is when narrowing occurs above the main pulmonary valve.The defect may occur alone. However, it can also occur with other heart defects. The condition can be mild or severe. It occurs rarely, in only about 10% of patients with congenital heart disease.Pulmonary stenosis can also occur later in life as a result of conditions that cause damage or scarring of the heart valves. These include rheumatic fever, endocarditis, and other disorders.SymptomsBluish coloration to the skin (cyanosis) in some patientsChest painFaintingFatiguePoor weight gain or failure to thrive in infants with severe blockageShortness of breathSudden deathNote: Patients with mild to moderate blockage may not have any symptoms. There may be no symptoms until the disorder is severe. Symptoms, when present, may get worse with exercise or activity.Signs and testsThe health care provider may hear a heart murmur by stethoscope. Tests used in the diagnosis of pulmonary stenosis may include:Cardiac catheterizationChest x-rayECGEchocardiogramMRI of the heartTreatmentSometimes, treatment may not be required.Percutaneous balloon pulmonary dilation (valvuloplasty) using a catheter can be successful for pulmonary valve stenosis that occurs without other heart defects.Surgery may be performed to repair the defect.Medications used before surgery may include:Anti-arrhythmics to improve the heart functionBlood thinners to prevent clotsProstaglandinsWater pills to remove the excess fluidExpectations (prognosis)As a general rule with mild stenosis, one-third of patients get better, one-third stay the same, and one-third get worse. The outcome is good with successful surgery or cardiac catheterization. Other congenital heart defects may also be a factor.ComplicationsCyanosisDeathHeart failureLeaking of blood back into the right ventricle (pulmonary regurgitation) after repairRight ventricular hypertrophy (enlargement)Calling your health care providerCall your health care provider if you have symptoms of pulmonary valve stenosis.Call your health care provider if you have treated or untreated pulmonary valve stenosis and you develop swelling (of the ankles or any area), difficulty breathing, or other new symptoms.ReferencesZipes DP, Libby P, Bonow RO, Braunwald E, eds.
