VCLIP Post-Market Study, Long-term Follow-up on LAA Exclusion Using AtriClip (VCLIP)

Long-term Follow-up on LAA Exclusion Using AtriClip, VCLIP Post-Market Study, CLINICAL TRIAL PROTOCOL: CP-2021-03

Retrospective-prospective, multi-center, non-randomized, unblinded, post-market study to evaluate the long-term performance and safety of AtriClip® FLEX-V LAA and PRO•V LAA Exclusion devices for exclusion of the left atrial appendage of the heart during concomitant cardiac procedures.

Study Overview

• Status: Completed
• Conditions: Left Atrial Appendage Absent
• Intervention / Treatment: Device: AtriClip

Detailed Description

The goal of this clinical trial is to evaluate the long-term performance and safety of AtriClip® FLEX-V LAA and PRO•V LAA Exclusion devices for exclusion of the left atrial appendage of the heart during concomitant cardiac procedures in participants for which a VCLIP was placed previously. Participants are consented and evaluated to confirm long-term performance of the AtriClip®.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: AtriClip group; Subjects eligible for evaluation are those who had undergone designated non-emergent, cardiac surgical procedure(s), received an AtriClip implant (with devices under investigation) and who were willing to return for follow-up chest imaging to ascertain Left Atrial Appendage (LAA) exclusion and met inclusion exclusion criteria.	Device: AtriClip; Received AtriClip for exclusion of left atrial appendage during concomitant cardiac procedure

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary Safety Endpoint	Incidence of the following serious adverse events within 30-days, if related tot he device and/or implant procedure: Death; Ischemic Stroke; Transient Ischemic Attack; Systemic Embolism; Hemorrhagic Stroke; Major Bleeding (BARC 3 and above); Surgical site infection; Pericardial effusion requiring intervention; Clinical diagnosis of myocardial infarction	30-days post-procedure
Primary Performance Endpoint	Left Atrial Appendage exclusion defined as absence of residual communication (≤3 mm residual communication with LAA) between the left atrium (LA) and the LAA as assessed by CTA or TEE imaging at the last follow-up visit. The images will be reviewed by an independent core lab using a standardized imaging protocol.	12-months or greater post-procedure, an average of 1.5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Performance	A residual LAA neck ≤10 mm as assessed by CTA or TEE imaging at the last follow-up visit	12-months or greater post-procedure, an average of 1.5 years
Long-term Thromboembolic Events	Incidence of thromboembolic events (ischemic stroke, TIA, systemic embolism) of any cause through the last follow-up visit.	12-months or greater post-procedure, an average of 1.5 years
Device and Procedure Long-term Safety	Number of Participants with Device or Procedure Related SAEs through the last follow-up visit	12-months or greater post-procedure, an average of 1.5 years
