Conference paper


Patients submitted to cardiac surgery for correction of congenital or acquired heart diseases may subsequently experience several types of atrial tachyarrhythmias [1–4]. Most of these are macroreentrant atrial tachycardias strictly related to the presence of scars, prosthetic materials, or conduits and have therefore been named “incisional” or “scar-related” atrial tachycardias. Although their electrocardiographic characteristics may resemble those of atrial flutter, slight differences in P wave morphology and tachycardia cycle length are present and should be identified in order to formulate the correct diagnosis. “Incisional” atrial tachycardia may occur at widely variable times after the operation, most frequently in patients submitted to septal atrial defect repair and Fontan or Mustard procedures for tricuspid atresia or great vessel transposition correction, respectively. The true prevalence of these arrhythmias is unknown; small retrospective series reported a prevalence of 32–57% after the Fontan procedure [4, 6, 7] and about 15% after the Mustard operation [3, 8].
