Principles and Techniques of the Three-Dimensional Electroanatomic Cardiac Mapping Approach in the Treatment of Intractable Atrial Macroreentrant Tachycardia Ablations

Year 2018, Volume: 21 Issue: 2, 108 - 110, 19.08.2018

Abstract

Introduction:
Challenging
and intractable macroreentrant atrial tachycardias mostly occur after cardiac
surgeries, and the response of such arrhythmias to conventional treatments is
poor. Also, arrhytmias with previous unsuccessful ablations are compulsive
arrhytmias. This study represents our approach for the ablation of challenging
atrial macroreentrant tachycardias.



Patients
and Methods:
Five consecutive patients with atrial þutter and a previous
history of cardiac surgery and/or radiofrequency ablation were enrolled to this
study. The focal point of the clinical arrhythmia was deÞned in the CARTO®
and Columbus™ map and the critical isthmus was targeted for ablation.
Radiofrequency ablation was performed until the arrhythmia stopped or until a
change in cycle length or activation wave front was seen.



Results: All the
complex atrial macroreentrant tachycardias were arized from the right atrium.
Overall, all the cases were successfully mapped and ablated. None of the
patients had recurrence even after 6 months of follow-up. The mean (±SD)
procedure time was 49.0 ± 22.4 min. Three-dimensional electroanatomic cardiac
mapping technologies, including CARTO and Columbus™, are highly effective in
revealing atrial arrhytmias and facilitating ablation of the scar-related
potential circuits.



Conclusion: This study highlights
success and usefulness of three-dimensional electroanatomic cardiac mapping in
complex atrial macroreentrant tachycardia ablations.

Üç Boyutlu Elektroanatomik Kardiyak Haritalama ile Zor ve Tedaviye Dirençli Atriyal Makroreentran Taşıkardi Ablasyonlarına Yaklaşım Prensipleri ve Teknikleri

Year 2018, Volume: 21 Issue: 2, 108 - 110, 19.08.2018

Abstract

Giriş: Zorlu ve dirençli makroreentran atriyal taşıkardiler çoğunlukla kardiyak
cerrahi sonrası oluşur ve konvansiyonel tedaviye verdikleri yanıt zayıftır.
Ayrıca, daha önceden başarısız ablasyon geçiren hastaların tedaviye yanıtları
daha dirençlidir. Bu çalışma ile zorlu atriyal makroreentran taşıkardilere
yaklaşımımızı paylaştık.



Hastalar ve
Yöntem:
Daha önceden kardiyak cerrahi geçiren ve/veya
radyofrekans ablasyon geçirmiş olan 5 atrial flutter hastası çalışmaya dahil
edildi. Klinik olarak izlenen aritmi odağı CARTO® ve Columbus™
haritalama yöntemi ile istmus işaretlenerek belirlendi. Aritmi sonlanana kadar
veya sikus uzunluğunda veya aktivasyon dalga boyunda değişiklik elde edilene
kadar radyofrekans enerji uygulandı.



Bulgular: Tüm kompleks atriyal makroreentran taşikardiler sağ atriyumdan orjin
alıyordu. Tüm olgular başarılı bir şekilde haritalandı ve ablasyon işlemi
uygulandı. Başarılı ablasyon uygulanan hastalarda 6 aylık takip süresince
rekürrens izlenmedi. Ortalama işlem süresi (±SS)  49.0 ± 22.4 dakikadır.  Atriyuma CARTO  ve Columbus™ üç boyutlu elektroanatomik
kardiyak haritalama teknolojileri kullanılarak tüm potansiyel devrelerin
başarılı ablasyonu skar ilişkili makroreentran atriyal taşıkardilerin
ablasyonunda yüksek oranda etkili bir yöntemdir.



Sonuç: Bu çalışma, kompleks
makroreentran atriyal taşıkardilerin ablasyonunda, üç boyutlu elektroanatomik
kardiyak haritalamanın başarısını ve kullanışlılığını vurgulamaktadır.
