Due to Medtronic's decisions to stop sales and distribution of the HVAD System and subsequent stop of study enrollments, limited data will be available. Therefore it is not expected to provide new insights.

Medtronic is sponsoring the Apogee International registry to further confirm safety and efficacy of the HVAD™ System when used as intended, in "real world" clinical practice and to enhance scientific understanding of the implant procedure, optimized blood pressure management, anticoagulation/ antiplatelet therapies, logfile analysis and acoustic spectrum analysis in patients receiving a Medtronic HeartWare™ HVAD™ for bridge to transplant and destination therapy indications.

Apogee International is a prospective, non-interventional, post-market, multi-site registry, conducted within Medtronic's Product Surveillance Registry (PSR) Platform. Enrollment into Apogee International will be comprised of newly implanted, commercial use patients with the HeartWare Ventricular Assist Device System (HVAD System).

Sites selected to participate are expected to collect data in at least one of these five modules:

1. Logfile Download;
2. Anti-coagulation / Anti-platelet Management;
3. Blood Pressure (BP) Management;
4. Acoustic Spectrum Analysis;
5. Infection Control

Inclusion Criteria:

• Patient or legally authorized representative provides written authorization and/or consent per institution and geographical requirements;
• Enrollment into Apogee International will be comprised of newly enrolled, commercial use patients with the HeartWare HVAD System;
• Patient is consented prior to the HVAD implant procedure.

Exclusion Criteria:

• Patient who is, or is expected to be inaccessible for follow-up;
• Participation is excluded by local law;
• Patient is currently enrolled or plans to enroll in concurrent drug/device study that may confound the PSR results.

Patients intended to be implanted with a HeartWare HVAD per the current (local) guidelines, are eligible for enrollment into Apogee International and must be consented for Apogee International prior to the HVAD implant.
