High-output heart failure from AV fistula
- Occurs when >20% of cardiac output is diverted through the access
- Branham sign (drop in HR after temporary access occlusion) is diagnostic
- Doppler US can accurately measure access flow rate and establish the diagnosis
- Tx = surgical banding of the access
