Abstract:
To analyse the clinical characteristics of children with atrial flutter(AF1), we reviewed(the medical records of the children who had been admitted and diagnosed as AF1 or 12 leads surface ECG during the period between February, 1986 and Octobe, 1990. The onset age of 25 children was evenly distributed between gestational period and upto 14 years of age. The sex ratio between boys and girls was 11:14. The cardiac abnormalities were detected in 21 children(dilated cardiomyopathy in 3, congenital heart defect in 18). In 4 children, AF1 occured in apparently normal heart. In 9 children, AF1 developed without relation to cardiac surgery(4 in normal heart, 3 in dilated cardiomyopathy, 2 in preoperative CHD). AF1 developed in 9 children within 30 days postoperatively(group A) and in 7, after 30 days postoperatively(group B). In group A, various types of operation were done. In 2 of them, AF1 persisted beyond the immediate postoperative period and 1 died of cardiac decompensation 3 months postoperatively. In group B, operative procedures before AF1 were Senning operation in 2, Fontan operation in 2, operation for tetralogy of Fallot, ventricular septal defect with severe tricuspid regurgitation, endocardial cushion defect in 1 each. Five children in group B( except 1 Senning operation and 1 Fontan operation) had significant residual atrioventricular regurgitation. The associated rhythm disturbance besides AF1 could be determined in 23 children. The sinus node dysfunction was associated in 8 ; the supraventricular dysrhythmia in 10; the ventricular dysrhythmia in 6; the atrioventricular conduction disturbance in 3, and no other associated rhythm disturbance in 6. The efficacy of various methods in conversion of AF1 to sinus rhythm were 57.1%(4/7) with DC cardioversion, 38.5%(5/13) with digoxin and other antiarrhythmic drug(amiodarone, beta blocker, quinidine, verapamil, flecainide), 25%(5/20) with pacing in esophagus or endocardium. The follow-up evaluation was possible in 24 children. Eight children were dead : 5 due to chronic decompensation, 2 due to sudden cardiac arrest, and 1 due to sepsis. Of the 16 alive children, 14 had recovered the normal sinus rhythm and the other 2 had persistent AF1. Twelve children without AF1 and 1 with persistent AF1 were on medication, Although there were none cardiac death in children without persistent AF1, 7 out of 9 children with persistent AF1 were dead. Of the 7 children with significant atrioventricular regurgitation, corrective procedures were done in 4. There were no death in these 4 children, despite of 2 cardiac death out of 3 children on whom corrective procedure were not done. In conclusion, the atrioventricular regurgitation was a significant factor in relation to the occurrence and persistence of AF1 and the prognosis was bad in children with persistent AF1. It is recommended to trat the children with AF1 associated with atrioventricular regurgitation promptly and more aggressively.
