Early Feasibility Study (EFS) Evaluating Percutaneous Repair of the Atrial Septum With a Novel PFO Occluder: The PROTEA-PFO Study
The goal of this clinical trial is to test a new heart device called P3 Occluder System in patients who have a small opening between the upper chambers of the heart (called a Patent Foramen Ovale or PFO) and have experienced a stroke that may be related to this heart opening. The main question it aims to answer is: • Is the P3 Occluder System safe and effective for closing a PFO in patients who have had a stroke that could be related to a PFO. Participants will: * Undergo the procedure to implant the P3 Occluder System, if deemed appropriate. * Visit their doctor at 1 month, 3 months, 6 months, 1 year, and 5 years after the procedure for follow up exams. * Answer a phone call from study staff at 2 years, 3 years, and 4 years after the procedure to answer a survey.
• Patient must be ≥ 18 and ≤ 65 years of age
• Diagnosis of PFO, defined as visualization of microbubbles per TEE in the left atrium within three cardiac cycles from the right atrial opacification demonstrating right-to-left shunting at rest and/or during Valsalva release.
• Ischemic stroke, defined as acute focal neurological deficit, presumed to be due to focal ischemia and confirmed by MRI or CT to have a neuroanatomically relevant cerebral infarct.
• Modified Rankin score (mRS) ≤ 3.
• Appropriate PFO anatomy for implantation of the investigational device as evaluated and determined by independent committee.
• Patient is willing and capable of providing informed consent.
• Prior to index procedure (7-day window), persons of childbearing potential must have a negative pregnancy test.
