Abstract Introduction Atrial fibrillation and atrial flutter originating from the donor s heart is a commonly reported complication post heart transplant. Case A 47-year-old male presented with atrial tachycardia 6 months post heart transplant. This arrhythmia was successfully terminated with radiofrequency ablation.

Atrial fibrillation (AF) is the most common heart arrhythmia and considered to be a progressive chronic disease associated with an increased morbidity and mortality. Recent data suggests a link between inflammation, oxidative stress and AF, although the underlying mechanisms are not fully understood.

BACKGROUND:The relationship between heart failure (HF) and atrial fibrillation (AF) is clear, with up to half of patients with HF progressing to AF. The pathophysiological basis of AF in the context of HF is presumed to result from atrial remodeling. We found that FOG2 repressed atrial gene expression promoted byTBX5.
