High-output cardiac failure from postbiopsy arteriovenous fistula

A 56-year-old kidney transplant recipient (transplantation 15 years prior for end-stage kidney failure from presumed arterionephrosclerosis, with no major complications, with estimated glomerular filtration rate of 30 ml/min per 1.73 m2) was admitted for worsening dyspnea, and orthopnea. She noted a beating mass, at the site of the kidney transplant.
