4 single-arm, open-label industry studies and 4 real-world practice studies

Authors' conclusion

Heart failure management with CardioMEMS leads to lower PAP, improved functional status and quality of life, and decrease of HFHs at 1 year in patients receiving the device in a real-life, non-RCT setting.
