About this study
Official title: An Cohort Study of Corheart 6 Left Ventricular Assist System for the Treatment of Patients With Advanced Left Heart Failure
This study aims to evaluate the long-term effectiveness and safety of Corheart 6 left ventricular assist system as a treatment for patients with advanced left heart failure. The patients who have received the Corheart 6 treatment since October 2021, or who are planned to received it, will be enrolled until the target sample size meets statistical requirements.
Data collected will include survival status, cardiac function status, quality of life, laboratory parameters and adverse events. The primary endpoint are the composite of survival at 6 months and, separately, at 24 months, defined as survival with device support, bridge to heart transplant and device explantation due to cardiac recovery, without disabling stroke (mRS > 3) or device replacement. Data collection will adhere to the follow-up schedule specified in the protocol.

What does the primary outcome measure?
Composite survival rate at 6 months. (time frame: 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2025.
