Should we be using bilateral carotid distal protection devices during the percutaneous closure of patent foramen ovale in patients with a history of paradoxical embolus?

Abstract

Percutaneous closure of patent foramen ovale (PFO) is becoming standard practice, particularly in patients with a history of embolic phenomena. The acute risk of cerebrovascular accident in patients undergoing this procedure is approximately 1%. We report the first successful use of bilateral carotid artery distal protection in this situation.
