Code:

NCT03503253

Conditions

Interventions

Interlock-35 Fibered IDC Occlusion System

Concerto Helix Detachable Coil System

Azur Peripheral Coil System

Study Details

Brief summary:

Although the clinical impact of left atrial appendage (LAA) leaks still requires confirmation, the open pouch with residual flow resulting from incomplete LAA closure may promote blood stagnation and thrombus formation, and increase the risk of thromboembolic events. The main purpose of this trial is to evaluate the safety and efficacy of percutaneous leak closure with detachable vascular coils.

Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Age> 18 years.
  • Presence of a significant LAA leak (moderate/severe following percutaneous occlusions or mild/severe after epicardial exclusions with the LARIAT suture delivery device).
  • Less moderate embolic risk (CHA2DS2-VASc ≥2)
  • High associated hemorrhagic risk (HASBLED ≥ 3), or absolute contraindication to OAC, or need for prolonged dual antiplatelet therapy, or history of thromboembolic events despite LAA occlusion/exclusion after other potential causes.
  • written informed consent obtained from subject or subject's legal representative and ability for subject to comply with the requirements of the study

Exclusion Criteria:

  • Life expectancy < 2 years.
  • pregnant, breastfeeding, or unwilling to practice birth control during participation in the study
  • presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data
