Second Annual PFO Patient Survey

We're conducting our second PFO Patient Survey. This survey is only for patients diagnosed with patent foramen ovale (PFO). If you have a PFO your answers to this survey could help other patients and the medical community alike to understand how PFO’s are being diagnosed and treated. The survey takes only a few minutes to complete and your answers will be completely confidential. Please fill out this survey only once and be sure to answer every question so we can keep the data as clean as possible. This survey is sponsored by the PFO Research Foundation, an organization launched by patients with PFO for the advancement of care of patients with PFO. Start the Survey Now!
