Does cyanosis in pulmonary valve stenosis occur in adults as well?
Snowed998
That is very rare to find cyanosis due to Heart disease in adult. But then any thing is possible in Biology.

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.

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.
How can pulmonary hypertension protect from pulmonary odema?
This precapillary vasoconstriction has been considered to protect the pulmonary capillary bed from excessive pressure increases in pulmonary venous hypertension and therefore to prevent fluid leak and edema formation (115, 135).
What is icd 9 code for neural foraminal stenosis?
The ICD-9 code for neural foranimal stenosis is 724.9. Foranimal stenosis is nerve compression of the nerve that leaves the spinal canal through the foramen. It can occur in the neck or lower back.
Who is at risk for pyloric stenosis?
Male infants with a family history of pyloric stenosis are more at risk of having the condition, which tends to occur less often in females, blacks, and Asians.
Where does blood formation occur in adults?
bones
Where does atherosclerotic blockage occur the most often?
Most often, atherosclerotic blockage or narrowing (stenosis) occurs in the femoral arteries
What is pulmonary infarction?
A Pulmonary Infarction is the death of a small area of lung resulting from pulmonary embolism. It occurs in a small, dead-end pulmonary artery and often causes pain in the back or chest.PI is an an infrequent consequence of Pulmonary Edema(< 10% of cases). It is sometimes due to thrombosis in situ of the pulmonary arteries as might occur in congenital heart disease associated with severe pulmonary hypertension or in hematologic disorders (eg, sickle cell anemia).
What happens when pulmonary vein and artery connect?
This is called a shunt. One that occur between the Pulmonary artery and the Pulmonary vein, would be a left to right shunt. So what would happen? The blood from the Pulmonary vein (having the high pressure) would enter the Pulmonary artery. The results would be that the blood just goes back to the lung for another cycle with be deoxygenated.
What are diastolic murmurs?
Those which occur during relaxation of the heart between beats are called diastolic murmurs. Those which occur during contraction of the heart muscle are called systolic murmurs
Can there be multiple blood clots in pulmonary embolism?
Yes, a person can have multiple pulmonary embolisms. They can have many small ones, or just one and can occur in just one lung, or both at the same time.
Do greenstick fractures occur primarily in sports injuries in adults?
False
