Prosthetic Aortic Valve Stenosis in End-Stage Renal Failure
Key result
Maintenance hemodialysis linked to rapid bioprosthetic aortic valve stenosis progression requiring repeat replacement.
- n=1
Why the study?
Does end-stage renal failure and hemodialysis accelerate the progression of prosthetic aortic valve stenosis in patients with bioprosthetic valves?

Implication
May support closer surveillance in hemodialysis patients with bioprosthetic valves; hypothesis-generating and should not yet change practice.
Key Points
- To investigate the effect of hemodialysis on the progression of prosthetic aortic valve stenosis in patients with end-stage renal failure.
- Descriptive case report of a 79-year-old female with a history of bioprosthetic aortic valve replacement and end-stage renal failure.
- Observation of clinical progression coinciding with initiation of hemodialysis and subsequent management through second valve replacement.
- Patient experienced stable prosthetic valve area for 6 years post-replacement, followed by progressive stenosis after starting hemodialysis.
- Post-second valve replacement, patient showed resolution of symptoms.
- Findings suggest hemodialysis may accelerate prosthetic aortic valve stenosis progression.

Outcome
Progression of prosthetic aortic valve stenosis
End-stage renal failure and hemodialysis may accelerate the progression of bioprosthetic aortic valve stenosis, suggesting a need for more frequent echocardiographic surveillance in this population.
Cite This Study
Mao et al. (2011) conducted a case report in Prosthetic aortic valve stenosis and end-stage renal failure (n=1). Maintenance hemodialysis was evaluated on Progression of prosthetic aortic valve stenosis. Maintenance hemodialysis in a 79-year-old woman with a previously stable bioprosthetic aortic valve coincided with rapid progression of prosthetic valve stenosis requiring a second replacement.
