Impact of Atrial Shunt Device on Heart Failure Patients

The chapter presents the results of a study on the effects of an atrial shunt device in heart failure patients with preserved ejection fraction, identifying factors associated with outcomes and responsiveness to the device. It discusses the long-term echocardiographic findings, showing consistent device functionality over two years with a high percentage of patients exhibiting a patent shunt. The analysis demonstrates improvements in cardiac structure and function, such as decreased left ventricle size and increased left atrial emptying fraction, with variations between responders and non-responders impacting patient outcomes.
