Large eustachian valve fostering paradoxical thromboembolism: passive bystander or serial partner in crime?

World J Cardiol. 2021 Jul 26;13(7):204-210. doi: 10.4330/wjc.v13.i7.204.ABSTRACTCatheter-based closure of patent foramen ovale (PFO) is more effective than medical therapy in the prevention of recurrent stroke[1]. It is likely that a proportion of patients evaluated for potential transcatheter PFO closure has actually different anatomical variants particularly common in the right atrium such as eustachian valve, Chiari network, Thebesian valve and Crista Terminalis. Notably, the eustachian valve may represent an increased risk factor for left circulation thromboembolism beyond that associated with PFO size and shunting. Such patients may benefit the most from percutaneous closure procedure.PMID:34367504 | PMC:PMC8326156 | DOI:10.4330/wjc.v13.i7.204
