International PFO Consortium
||Secondary Stroke Prevention in Patients with Patent Foramen Ovale: The International PFO-Consortium
||David E. Thaler, MD, PhD
The purpose of this study is to learn more about how often people with PFOs have a second stroke after having the first one. This registry will investigate the impact of age, blood thinning drugs (such as aspirin and Coumadin), and closure of the PFO on the risk of stroke.
- Men and women older than 18 years with ischemic stroke or TIA within the previous 3 months
- Diagnosis of PFO established by transesophageal echocardiography (TEE)
- Informed consent
- History of brain bleeding and/or aneurysm
- Contraindications for TEE or iodine
Information about the patient’s health will be collected every 12 months for up to 3 years. If the patient does not have a scheduled visit with their doctor at that time, they will be contacted by telephone to provide the information.
