Abstract

We describe a case of persistant atrial tachycardia/flutter in a 19-year old female with corrected transposition of great arteries (ccTGA) and dual inlet left ventricle (DILV), treated with surgical palliative operations. The arrhythmia became persistent and symptomatic with dyspnea and severe cyanosis. During the EP study, the right atrial isthmus-dependant reentry was identified. In electroanatomical maps large areas of low voltage and electrical silence were localised. Due to these areas of slow conduction the isthmus dependent arrhythmia had long CL. Linear RF applications closed the isthmus, resulting in flutter termination. During 3 months of follow-up the patient remained free of arrhythmia.
