Key result
Surgical aortic valve replacement resulted in recovery from dialysis-dependent kidney disease in a 55-year-old female with severe aortic stenosis and CKD Stage 5.
Why the study?
It is often difficult to determine the primary cause of renal dysfunction in patients with simultaneous cardiac and renal disease, leading to hesitation in operating on end-stage kidney disease patients.

Does surgical aortic valve replacement improve renal function in patients with severe aortic stenosis and dialysis-dependent CKD?
Surgical aortic valve replacement can reverse dialysis-dependent kidney disease in patients with severe aortic stenosis, highlighting the importance of identifying cardiac-driven renal dysfunction.
Inadequate peripheral perfusion due to cardiac diseases can worsen renal function in patients with chronic kidney disease (CKD). Due to the nature of the simultaneous cardiac and renal disease, it is often difficult to determine which is the primary cause, and hence many surgeons hesitate to operate on patients with end-stage kidney disease. However, when the primary cause is cardiac related, renal function can improve after successful cardiac surgery. Here, we describe a 55-year-old female patient with CKD Stage 5 who was on maintenance hemodialysis with severe aortic stenosis (AS) and underwent surgical aortic valve replacement and recovered from dialysis-dependent kidney disease. Drastic improvement in renal function after cardiac surgery can occur even in patients with CKD due to improved renal perfusion, especially in cases of AS. Therefore, diagnosing the primary cause of renal dysfunction is essential.

Kumar et al. (2023) conducted a case report in Severe aortic stenosis and chronic kidney disease (CKD) Stage 5 (n=1). Surgical aortic valve replacement was evaluated on Recovery from dialysis-dependent kidney disease. Surgical aortic valve replacement resulted in recovery from dialysis-dependent kidney disease in a 55-year-old female with severe aortic stenosis and CKD Stage 5.
