Θεραπεία υπερκοιλιακών ταχυκαρδίων με κατάλυση
INTRODUCTION: Radiofrequency catheter ablation is a well established procedure
for the treatment of supraventricular tachycardias with high success rates. The
long term follow-up of patients underwent this procedure, is recommended in
order to estimate the presence of permanent therapeutic result and the effect
on their quality of life.
AIM: The aim of the study is to confirm the value of the radiofrequency
catheter ablation for the treatment of supraventricular tachycardias and its
effect on the quality of life of patients who underwent this procedure.
PATIENT ENROLLMENT-METHODS: 76 symptomatic patients enrolled in the study (40
males and 36 females). The average age was 51±14y/o for the male and 55±19y/o
for the female population. All the patients underwent completeelectrophysiology
study using the same procedural protocol in order to induce theirclinical
arrhythmia and elucidate its mechanism. Following the diagnostic part of
thestudy all the patients underwent radiofrequency catheter ablation. The
quality of life ofthe patients was estimated with frequent telephone follow-ups
and completion of standard quality of life questionnaires.
RESULTS: In 43 patients (56,57%) AV nodal tachycardia was induced, in 9
patients (11, 83%) AV reentrant tachycardia using an accessory pathway was
induced, one patients (1,31%) had atrial tachycardia, 14 patients (18,42%) had
atrial flutter and three patients (3,94%) atrial fibrillation. All patients
underwent radiofrequency catheter ablation. In 71 patients (93,42%) the
successful and in 3 patients (3,94%) was failed. In the long-term follow-up
eight (8) patients had recurrence of their arrhythmia (10,42%). Sixty (78,94%)
patients declare that the procedure improved their quality of life and 59
patients (77,63%) they would repeat the procedure anyway if this was necessary.
CONCLUSION: Electrophysiology studies followed by radiofrequency catheter
cablation are the procedure of choice for the treatment of supraventricular
arrhythmias. They indeed eliminate the arrhythmia episodes, they are safe and
improve the quality of life.
