SUMMARY

ASSESSMENT ON RADIO FREQUENCY ABLATION OF ACCESSORY
PATHWAY AT HUE CARDIOVASCULAR CENTRE
Introduction, method and materials: Accessory pathway is still the common substrate for
SVT and the main subject in EP ablation practice in Vietnam. We conducted a retrospective
study on 32 patients having EP ablation for AP at Hue Cardiovascular Centre.
Results: 19 males and 13 females with mean age of 41,9 ± 16,1 ranging from 17 years to 68
years were studied. 24 patients had WPW syndrome and 8 concealed AP. WPW were seen more
frequent in male than female patients (89.47% vs. 53.8%). All patients were successfully treated
by RF ablation.
Left AP were on the left than on the right side (62.5% vs. 37.5%). There was no significant
relation between the site of AP and gender of patients.
60 % of left AP were lateral. Ategrade transeptal mapping was the technic of choice with
success rate of 95% (19/20 cases). Transeptal technic time was 6.5 ± 2.33 min, time from
ategrade mapping to successful ablation was 9.47 ± 4.33 min.
83,3% right AP were septal. Right side mapping time was longer as compared to the left
side (20.17 ± 35.09min vs. 9,47 ± 4,33min).
Conclusion: The most common sites of AP were left lateral and right septal. The success
rate was extremely high 100% with the help of transeptal puncture and Halo catheter for the right
sided AP, especially for the right lateral.
