Avoiding anticoagulation drugs on the post-operative atrial fibrillation
made successful conservative treatment for left atrial dissection: A
Abstract Introduction: Left atrial dissection is a rare complication of
cardiac surgery, most commonly associated with mitral valve surgery.
Herein, we report on successful conservative treatment of left atrial
dissection by avoiding anticoagulation. Case Report: A 64-year-old man
developed left atrial dissection due to retrograde cardioplegia
cannulation during operation for acute type A aortic dissection. As
there was no connection between the left atrial dissection cavity and
the left atrium on enhanced computed tomography, we did not administer
anticoagulants to prevent expansion of the left atrial dissection
cavity. However, the patient developed atrial fibrillation, which was
successfully managed by beta-blocker and amiodarone administration.
Follow-up imaging showed gradual left atrial dissection reduction, and
the patient was started on anticoagulation therapy. Conclusion: We were
able to resolve left atrial dissection by preventing the use of
anticoagulation therapy in the acute stage by managing the atrial
fibrillation with antiarrhythmic drugs.
