A 91-year-old woman with severe aortic stenosis successfully underwent maintenance hemodialysis via arteriovenous fistula after transcatheter aortic valve implantation: A case report with literature review

BackgroundTranscatheter aortic valve implantation (TAVI) has evolved to be a treatment of choice in high-risk patients with aortic stenosis (AS). However, it is not known whether TAVI is safe and beneficial for the creation of arteriovenous fistula for maintenance hemodialysis in high-risk patients with severe AS.Case presentationA 91-year-old woman was referred to our hospital due to oligoanuria and progressive renal dysfunction. She was diagnosed with anti-glomerular basement membrane (GBM) disease. She had hypertension, chronic kidney disease stage G3b, and AS. We chose not to perform immunosuppressive therapy and plasmapheresis for anti-GBM disease because the risk of death outweighed the benefit of treatment. Hemodialysis with a venous catheter was initiated for the renal indication. As she showed severe AS, she had a risk of cardiac decompensation after arteriovenous fistula creation for dialysis. Following the clinical decision-making process, she underwent TAVI. Although she required the implantation of a cardiac pacemaker for an advanced atrioventricular block that occurred 11 days after TAVI, arteriovenous fistula was successfully created thereafter. She could undergo maintenance hemodialysis using arteriovenous fistula.ConclusionsTAVI is safe and beneficial for the creation of arteriovenous fistula shortly after initiating acute hemodialysis using a catheter in a very old patient with anti-GBM disease.
