In the past few months i have had to cardiac ablations. one for flutter the other for afib. in between i had a stroke. now i hear i have a shunt?

What's your question: Atrial flutter is typically a short-lived dysrhythmic event, although in some cases, such as yours, elective cardioversion or ablation is required. Atrial fibrillation can be paroxysmal or chronic. Regardless, Afib is associated w/incr risk of stroke which can be mitigated via oral anticoagulants (blood thinners). You may have an ASD or PFO which are common. Check out https://goo.gl/KStW4p

Shunt post RFA: The “shunt" is a residual atrial septal defect (ASD) from the transseptal access for AF ablation - not uncommon. Over 80% of ASD's close/heal within 6 months and rarely require any intervention. ASD size depends on sheath size used and how performed - double puncture vs double access via single puncture - are larger. Cryo uses larger sheaths than RFA approach, therefore, larger residual ASD.
