For 25% of the population, a hole in the heart, called a PFO can lead to stroke or death. Today a PFO can be repaired with a catheter-based device called an Amplatzer PFO Occluder. Yesterday, AZTV broadcast this event live, and Dr. Rizik discusses the procedure. You can catch an encore presentation of “The Procedure,” Saturday at 4pm on AZTV 7. You can also view all previous episodes of “The Procedure” at aztv.com/procedure.
