Stenosis is narrowing
Stenosis leads to valvular heart disease
Valves prevent backflow of blood
Regurgitation is the inability to prevent backflow
Aortic and mitral valve disease are termed left heart disease
Aortic and mitral valve are more common due to higher pressure
Stenosis of the aortic valve shows thickness of the leaflets
Blood leaves the left ventricle through the aorta
Mitral stenosis is caused largely by rheumatic heart disease
Mitral stenosis is uncommon
Pulmonary and tricuspid valve disease are right heart diseases
Pulmonary valve diseases are the least common in adults
Aortic stenosis and regurgitation may include heart failure symptoms
Aortic stenosis may show a normal chest x-ray
Calcifications on chest x-ray is uncommon
Aortic stenosis may show dilation of the left ventricle on chest x-ray
Aortic stenosis typically shows left ventricle hypertrophy or left heart strain
Echocardiography is the gold standard diagnosis for aortic stenosis
Aortic stenosis echocardiography can show left ventricular hypertrophy, leaflet calcification, abnormal leaf closure
Aortic regurgitation will have normal pump function during systole
Aortic regurgitation echocardiogram will show reverse blood flow during diastole
Mitral stenosis can show an enlarged left atrium
Calcifications of aortic leaflets is more related to lipoprotein deposits and inflammation
