Abstract
|
|
|
Atrial flutter is a potentially life threatening complication of repair or palliation of congenital heart disease and is frequently drug resistant. Recent studies in human have demonstrated that common type atrial flutter is due to macro-reentry
in
the
right atrium and that the reentrant circuit may involve slow conduction in the low posteroseptal area of the right atrium. Catheter ablation of atrial flutter has been successful using radiofrequency energy.
Application of radiofrequency energy at the isthmus between the inferior vena cava and tricuspid ring was effective in preventing recurrence of atrial flutter in a 6 year old boy after open heart surgery of common atrium. Despite concerns
regarding
ablation scar in growing children and persistence of underlying structural abnormalities in postoperative patients, radiofrequency ablation of atrial flutter appears to be another useful therapeutic option in management of this not so rare but
potentially malignant and often resistant arrhythmia.
