Atrial Flow Regulator: Should We Be Afraid of It?

The atrial flow regulator (AFR) is an innovative technology to treat patients with symptomatic heart failure and increased left atrial pressure, particularly heart failure with preserved ejection fraction (HFpEF). This device is implanted percutaneously in the interatrial septum to create a left-to-right shunt that may either reduce the abnormal pressure rise occurring initially during exercise in the left atrium in HFpEF or keep elevated left atrium pressure lower at rest in more advanced cases.
