Successful radiofrequency ablation of accessory pathway associated with left atrial appendage aneurysm in a low birthweight premature patient

Tachyarrhythmias are common cardiac arrhythmias in newborns and infants.We present a premature case with a 2.4-kg birth weight, with non-immunehydrops due to supraventricular tachycardia. Despite the combination ofamiodarone, esmolol and flecainide, tachyarrhythmia could not be controlledand radiofrequency ablation was applied due to left ventricular dysfunction.After the procedure the rhythm returned to normal sinus and left ventricularfunctions improved rapidly. The follow-up of the case continues without anyproblems. In this presentation, successful ablation of the accessory pathwayassociated with structural heart disease have been covered in the youngestand smallest patient to date.
