Valvular stenosis
Valvular Stenosis
Valvular stenosis (/vælˈvjuːlər stɪˈnoʊsɪs/) is a medical condition characterized by the narrowing, stiffening, thickening, or blockage of one or more of the heart valves.
Etymology
The term "valvular" is derived from the Latin word "valvula", meaning "small valve", and "stenosis" comes from the Greek word "stenosis", meaning "narrowing".
Types of Valvular Stenosis
There are four main types of valvular stenosis, named after the valve they affect: aortic, mitral, pulmonary, and tricuspid.
Aortic Stenosis
Aortic stenosis is a condition where the aortic valve becomes narrowed, restricting blood flow from the heart to the rest of the body.
Mitral Stenosis
Mitral stenosis is a condition where the mitral valve becomes narrowed, restricting blood flow from the left atrium to the left ventricle of the heart.
Pulmonary Stenosis
Pulmonary stenosis is a condition where the pulmonary valve becomes narrowed, restricting blood flow from the right ventricle to the pulmonary artery.
Tricuspid Stenosis
Tricuspid stenosis is a condition where the tricuspid valve becomes narrowed, restricting blood flow from the right atrium to the right ventricle of the heart.
Symptoms
Symptoms of valvular stenosis can include chest pain, shortness of breath, fatigue, and syncope.
Diagnosis
Diagnosis of valvular stenosis typically involves a physical examination, echocardiogram, and possibly a cardiac catheterization.
Treatment
Treatment for valvular stenosis can include medication, balloon valvuloplasty, or heart valve surgery.
