[Risk factors of late ventricular arrhythmias after total correction of tetralogy of Fallot in children].
The authors present an analysis of pre-, intra- and postoperative risk factors of late ventricular arrhythmias in 100 children in 5-12 years after total correction of the tetralogy of Fallot. Complex arrhythmias (III-V class according to Lown classification) were found in 19% of patients. Risk factors were: in the pre- and intraoperative period--marked endocardial fibrosis of the right ventricular outflow tract, long bypass time (> 180 min) and aortic cross-clamp (> 90 min), in the post-operative period-left ventricular dysfunction in echocardiographic examination and age > 10 years at time of the study. Complex ventricular arrhythmias were more frequent in patients with associated supraventricular arrhythmias and with progressive bundle branch block.
