Radiofrequency Ablation Needles Are Age Appropriate

Radiofrequency ablation (RFA) is to send the electrode catheter to a specific part of the heart cavity through vascular puncture to find the abnormal conduction path of the heart or the location of ectopic pacemaker, and then discharge ablation after fine mapping. In general, radiofrequency ablation is an option when the number of premature beats is greater than 10, 000 per day and the location of the lesion is convenient for catheterization. Tachyarrhythmia in children is also usually treated by radiofrequency ablation. It is characterized by a sudden acceleration of the heart rate, which can be as high as 180 to 300 beats per minute. There is no radical treatment other than radiofrequency ablation. [1]

Arrhythmias may persist for a long time, such as premature beats, most of which will last for seven or eight years, or even more than ten years, and preexcitation syndrome will persist for a lifetime. Severe arrhythmia attack, the child's activity is limited, poor quality of life, if repeated attack, after a long time will cause heart enlargement, cardiac function decline, should be treated as soon as possible.

For some arrhythmias, such as premature beats, drugs do not shorten the course of the disease, but only relieve the symptoms. Besides, drugs are toxic. If they are used all the time, the children will lose more than they gain. Therefore, the arrhythmia should be treated only when it affects the child's quality of life and physical condition, and radiofrequency ablation can be used when appropriate.

However, due to the characteristics of small blood vessels and small heart in children, the implementation of radiofrequency ablation is difficult and risky, so it needs to be carefully chosen. For children under 3 years of age with tachyarrhythmia, medical treatment should be given first, and radiofrequency ablation surgery should be considered for children over 3 years of age.
