Atrial flutter may be a sequela of open heart surgery. After cardiac surgery, atrial flutter may be re-entrant as a result of natural barriers, atrial incisions, and scar. Some patients develop atypical left atrial flutter after pulmonary vein isolation for atrial fibrillation.
No clearly defined genetic conditions cause atrial flutter, but in many cases there is likely an underlying genetic susceptibility to acquiring it. Genome-wide association studies have identified genes associated with atrial flutter.
Rarely, mitral valve prolapse or acute myocardial infarction has been associated with atrial flutter. The following conditions are also associated with atrial flutter:
Chronic obstructive pulmonary disease
Myotonic dystrophy in childhood (rare)
