[Effectiveness and safety of catheter ablation of the heart conduction tracts in tachyarrhythmia].
An analysis of 490 operations of radiofrequency catheter destruction in 442 patients aged from 5 to 83 years has been made. 284 patients (64.3%) had congenital and "idiopathic" character of rhythm disturbances. The greater part of operations--459 (93.7%)--were performed on patients with supraventricular tachycardias, 31 operations (6.3%)--on patients with ventricular arrhythmias. Efficacy of operations on patients with congenital diseases of the conducting system of the heart was 94.8-100%, frequency of recurrences being 3.3-8%. Successful rhythm correction in 78% of patients with atrial flutter was due to the risk of appearance of recurrences and development of atrial fibrillation at late periods. Creation of atrio-ventricular blockade abolishes tachysystole in patients with ciliary arrhythmia, but life quality depends on the adequate system of stimulation. The frequency of complications after the catheter destruction is associated with the complex character of the intervention and increases when the manipulations are to be performed in the left chambers of the heart.
