[Rapid development of mitral and aortic stenoses with chronic hemodialysis. A report of 2 cases].

Chronic renal failure is associated with a high incidence of calcifications of the mitral anulus, which if severe enough may result in mitral stenosis or regurgitation. Aortic valve calcifications, though less frequent, may also occur and cause aortic valve stenosis, as observed in two patients. In hemodialysed patients, identification of valvular aortic stenosis might be difficult on a clinical basis since the systolic ejection murmur might be attributed to aortic sclerosis or a high output state and left ventricular hypertrophy to previous hypertensive disease. Calcific aortic stenosis may easily be detected using echocardiography combined with the continuous Doppler technique.
