Causes
Pulmonary stenosis is a relatively rare heart condition in cats characterized by a narrowing of the pulmonaryPulmonary refers to the lungs or the respiratory system. Pulmonary diseases in dogs and cats include conditions such as Pneumonia, asthma, and pulmonary hypertension. valve or adjacent tissue. This narrowing prevents blood from flowing efficiently from the right ventricleA ventricle is one of the two lower chambers of the heart that pump blood into the arteries. The right ventricle pumps blood to the lungs, while the left ventricle pumps blood throughout the body. of the heart into the pulmonaryPulmonary refers to the lungs or the respiratory system. Pulmonary diseases in dogs and cats include conditions such as Pneumonia, asthma, and pulmonary hypertension. arteryAn artery is a blood vessel that carries blood away from the heart. Unlike veins, which return deoxygenated blood to the heart, arteries transport oxygen-rich blood to the body's tissues.. As a result, the heart has to exert more force to pump the blood through the narrowed passage / transitPassage refers to the passage / transit or transport of substances through the body or within body cavities and channels, such as the digestive tract or airways., which can lead to thickening (hypertrophyHypertrophy is the enlargement of an organ or tissue due to an increase in cell size. It can occur as a normal response to increased stress or demands, such as muscle hypertrophy from training, or be pathological, such as enlargement of the heart muscle due to high blood pressure.) of the heart muscle.
There are various forms of pulmonary stenosisPulmonary stenosis is a heart defect in which a narrowing of the outflow opening of the right ventricle or the subsequent pulmonary artery obstructs blood flow from the right ventricle to the lungs. This can lead to symptoms such as lethargy, shortness of breath, and, in severe cases, heart failure., including valvular, subvalvular, and supravalvular stenosisA stenosis is a narrowing or constriction of a body channel or opening that can impede the normal flow of fluids or other substances, such as blood in arteries or air in the airways.. In the valvular form, which is the most common, the narrowing is limited to the valve leaflets themselves. Subvalvular stenosisA stenosis is a narrowing or constriction of a body channel or opening that can impede the normal flow of fluids or other substances, such as blood in arteries or air in the airways. refers to narrowing below the valve, while supravalvular stenosisA stenosis is a narrowing or constriction of a body channel or opening that can impede the normal flow of fluids or other substances, such as blood in arteries or air in the airways. occurs above the valve.
The exact causes of pulmonary stenosisPulmonary stenosis is a heart defect in which a narrowing of the outflow opening of the right ventricle or the subsequent pulmonary artery obstructs blood flow from the right ventricle to the lungs. This can lead to symptoms such as lethargy, shortness of breath, and, in severe cases, heart failure. in cats are not fully understood. However, it is believed that genetic factors may play a role, as this condition is more common in certain cat breeds.
