Lead Sponsor:

Occlutech International AB

Conditions:

Stroke

PFO - Patent Foramen Ovale

Eligibility:

All Genders

18-65 years

Brief Summary

Percutaneous transcatheter closure of a patent foramen ovale (PFO) to reduce the risk of recurrent ischemic stroke in patients who have had a cryptogenic stroke due to a presumed paradoxical embolism.

Detailed Description

This study aims to investigate stroke recurrence rates after interventional PFO closure with an Occlutech PFO Occluder in patients who have experienced at least one ischemic cryptogenic stroke attribu...

Eligibility Criteria

Inclusion

  • Age ≥18 years and ≤65 years
  • At least one event of cryptogenic ischemic stroke in the last 12 months
  • Presence of a PFO indicated for device-assisted closure (in compliance with the Instruction for Use) confirmed by common practice procedures
  • A large PFO (maximum separation of the septum primum from the secundum) of ≥2 mm confirmed by common practice procedures, or an ASA defined by common practice procedures as septum primum excursion of ≥10 mm
  • Life expectancy of at least 1 year
  • Ability to speak fluently and to understand the language in which the study is being conducted
  • Written, informed consent by the patient for participation in the study and agreement to comply with the follow-up schedule

Exclusion

  • Acute infection(s)
  • Known coagulation disorder

  • Atrial Tumor
  • Allergies to nickel and/or titanium and/or nickel/titanium-related material
  • Inability to achieve adequate oral anticoagulation therapy and/or platelet inhibition post intervention
  • Intolerance to contrast agents
  • Participation in another clinical investigation \<30 days before intended Occlutech PFO Occluder implantation procedure (note that in line with Medical Device Reporting, registries are not considered as clinical investigations)
  • Contraindication to use of trans-esophageal echocardiography (TEE) and/or use of general anesthetic
  • Eisenmenger Syndrome
  • Recent pelvic venous thrombosis
  • Myocardial infarction or coronary artery bypass surgery within the last 30 days
  • Atrial thrombus
  • Patients whose size or condition would cause them to be a poor candidate for cardiac catheterization (e.g. too small for echocardiography imaging probe, catheter size, vasculature size, active infection, body weight \<8 kg)
  • The following exclusion criteria are at the discretion of the investigator:
  • Stroke of any other origin
  • Large artery atherosclerosis
  • Small vessel disease
  • Arterial dissection
  • Hypercoagulable disorder
  • Uncontrolled hypertension
  • Uncontrolled diabetes
  • Autoimmune disease
  • Evidence of drug or alcohol abuse
  • Chronic, persistent, or paroxysmal atrial fibrillation or atrial flutter
  • End-stage heart-, liver-, lung-, or kidney disease
  • Cardiac tumor
  • Endocarditis or septicemia
  • Severe valvular pathology
  • Any condition that, in the opinion of the investigator, might interfere with the implantation,might affect the patients' well-being thereafter or might interfere with the conduct of the study
