title: What is the mechanism of the atrial arrhythmia in a patient after orthotopic heart transplantation?
abstract: Atrial arrhythmias are quite common in patients after heart transplantation; they can occur via focal or reentrant mechanisms and are amenable to curative therapy with catheter ablation. Integration of the individual patient's surgical anatomy with the arrhythmia pattern on 12-lead electrocardiogram can help both to narrow the potential arrhythmia diagnoses and to facilitate therapeutic decision making. This case highlights the differential diagnosis and management of such a patient.
