Atrial Shunt Devices Under Development for the Treatment of HFpEF

These devices include the Interatrial Shunt Device (IASD), the V-Wave Shunt, and the Atrial Flow Regulator (AFR) as left atrium (LA) to right atrium (RA) shunts and the Transcatheter Atrial Shunt System as a LA to coronary sinus (CS) shunt. HFpEF = heart failure with preserved ejection fraction.
