Transfemoral transcatheter aortic valve replacement via TEE guiding in a severe aortic regurgitation with Stanford type B aortic dissection：A case report

A 82-year-old patient admitted to hospital due to a severe dyspnoea, diagnosed as severe aortic regurgitation (AR) with chronic Stanford type B aortic dissection, chronic renal failure. Transcatheter aortic valve replacement (TAVR) was performed using the transfemoral route by guidance of transoesophageal echocardiography (TEE). This case demonstrates that TVAR is an available and safe treatment for severe AR with chronic type B aortic dissection.
