Clinical Trial Summary

Hong Kong and Taiwan HM3 PMS is a prospective, single arm, post market surveillance is designed to evaluate clinical and functional outcomes with the HM3 LVAS as a treatment for advanced heart failure. The PMS will enroll approximately 30 patients, that meet the HM3 commercially approved labelling indications, from approximately 4 sites in Hong Kong and Taiwan. PMS participants will be followed until the 24 months follow-up visit or until they experience an outcome, whichever comes first.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Efficacy Endpoint: Number of participants with overall survival to transplant, myocardial recovery or on device support free of debilitating stroke (Modified Rankin Score >3) or reoperation for pump replacement	Overall survival to transplant, myocardial recovery or on device support free of debilitating stroke (Modified Rankin Score >3) or reoperation for pump replacement will be assessed using the Kaplan-Meier product-limit method along with a competing outcomes graph. Subjects who are urgently transplanted due to a HeartMate 3 malfunction will be considered to have experienced a primary endpoint event, as will subjects who expire, suffer a debilitating stroke or have their HeartMate 3 exchanged due to a device failure. Subjects who are transplanted (except as described above), explanted for recovery, withdraw from the trial or are lost to follow-up will be censored at that time in the analysis.	Throughout the study (approximately 24 months post implant)
Primary	Primary Safety Endpoint: Number of cumulative occurrence of adverse events	Cumulative occurrence of adverse events will be presented as percent of patients with adverse events and events per patient year of support.	Throughout the study (approximately 24 months post implant)
Secondary	Mean change in Six-minute Walk Test from baseline	The 6-minute Walk test will be conducted at all follow-up visits until the end of the surveillance period. The overall mean, median, standard deviation, minimum and maximum will be presented for all follow-up visits. Differences in walking distance between each visit and baseline will be calculated and assessed for improvements using paired, nonparametric Wilcoxon signed-rank test. In addition, box plots will be used to show changes in walking distance over time.	At 1 month post implant

Secondary	Change proportion of New York Heart Association (NYHA) Functional Status from baseline	Subjects' NYHA Functional Status will be assessed at all scheduled follow-up visits until the end of the surveillance period. Percent of subjects in each NYHA class will be presented for all follow-up visits. For comparison, patients will be grouped into NYHA Class I/II (No limitation and Slight limitation of physical activity) vs. NYHA Class III/IV (Marked limitation and Inability to carry out physical activities). McNemar's test will then be used to assess if there is an increase in proportion of Class I and II subjects at each visit comparing to the baseline.	At 1 month post implant
