A 91-year-old woman was admitted to our hospital for treatment of congestive heart failure with severe aortic stenosis. After admission, she developed a high fever due to pneumonia and worsened heart failure. We could not perform transcatheter aortic valve implantation (TAVI) because of active infection; therefore, retrograde balloon aortic valvuloplasty (BAV) was urgently performed. A complete atrioventricular block and severe functional mitral regurgitation appeared suddenly after BAV in the absence of mechanical disorders. Her condition improved after several days in our intensive care unit. Pacemaker implantation and TAVI were then performed, and the patient was discharged from our hospital. MR could sometimes exacerbate after BAV in clinical practice; therefore, we set out to report this case.
