Patients on chronic hemodialysis can experience extremely rapid progression to severe aortic stenosis, warranting frequent echocardiographic monitoring.
May warrant closer echocardiographic surveillance in hemodialysis; hypothesis-generating and leaves open whether intensified monitoring improves outcomes.
The incidence of aortic stenosis (AS) is increasing, and the progression of AS is more rapid in chronic renal failure patients treated by dialysis than those in the general population. We present 2 cases of rapid progression of AS in chronic renal failure patients treated by dialysis. Both cases had no findings of AS at the first echocardiographic examination. After 3.5 years (case 1) and 2 years (case 2) later, severe AS was noted in both patients. The progression of AS was more rapid in our 2 cases compared with previous reports. Frequent echocardiographic examination should be performed to evaluate valvular calcification and stenosis in patients with chronic renal failure treated by chronic dialysis.
