Successful Percutaneous Transcatheter Aortic Valve Replacement for Severe Aortic Regurgitation in a High-risk Patient with Cardiorenal Syndrome.

The absence of a Food and Drug Administration-approved percutaneous valve technology for the treatment of severe aortic regurgitation (AR) presents a challenge for high-risk patients. In this report, we describe the successful treatment of an 84-year-old male patient suffering from severe symptomatic AR and concomitant cardiorenal syndrome with renal failure using a 34 mm Evolut R (Medtronic) self-expanding transcatheter aortic valve replacement. This intervention resulted in the resolution of AR, cardiorenal syndrome, and congestive heart failure symptoms.
