High-Output Heart Failure Associated With Arteriovenous Fistula

Key Result

Echocardiography combined with transient AVF flow reduction during testing can reverse high-output heart failure and confirm AVF-related diagnosis.

Key Points

• This research aims to investigate the relationship between arteriovenous fistulas (AVFs) and high-output heart failure (HOHF).
• Utilized echocardiography to assess heart function
• Conducted hemodynamic testing with transient flow reduction
• Analyzed the reversibility of high-output states
• Demonstrated that transient flow reduction can reverse the high-output state
• Supported the diagnosis of AVF-related HOHF through echocardiographic findings
