A member asked:

Is flecainide dangerous with a pfo closure ?

A doctor has provided 1 answer

NO: Flecainide has been shown to be dangerous in the early period following a myocardial infarction (CAST study). That concern is extrapolated to avoid use in anyone with previous MI. The mechanism is related to scarred ventricular myocardium. PFO closure doesn't involve the ventricles and shouldn't be a problem. Flec is great for AF which is an atrial problem, like PFO closure.
