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

Background: Transcatheter 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 presentation: A 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. Conclusions: TAVI 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.
