Scheduled Maintenance for updates to Merlin.net PCN HF Portal

We're making updates to the Merlin.net PCN HF Portal. As a result, the Merlin.net PCN HF Portal will be offline starting Friday, November 13, 2026 at 5 PM through Sunday, November 15, 2026 at 5 PM while these changes are implemented. During this time, CardioMEMS HERO Device and Patient Electronic System readings will not be sent immediately but will save to the device and should automatically upload once service is restored. If you experience any issues after service is restored, please contact Abbott HF Technical Support at 844-692-6367 (Mon-Fri, 8 a.m.-8 p.m. EDT). Thank you for your patience as we complete these updates.
