📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: Radiofrequency (RF) ablation is a highly successfulprocedure for the management of typical atrial flutter(AFL), an abnormal heart rhythm originating within the atria.There is no strong evidence that the use of contact force (CF)has any impact on procedural duration or acute success inthe management of cavotricuspid isthmus (CTI)-dependentAFL.
📊
Key Findings & Data:The aim of this study was to compare acute proceduralparameters using a non-CF, 4-mm, gold-tip, irrigated catheterand a CF-sensing catheter in patients with AFL.Methods: This was a retrospective cohort study.

Abstract

Objective: Radiofrequency (RF) ablation is a highly successfulprocedure for the management of typical atrial flutter(AFL), an abnormal heart rhythm originating within the atria.There is no strong evidence that the use of contact force (CF)has any impact on procedural duration or acute success inthe management of cavotricuspid isthmus (CTI)-dependentAFL. The aim of this study was to compare acute proceduralparameters using a non-CF, 4-mm, gold-tip, irrigated catheterand a CF-sensing catheter in patients with AFL.Methods: This was a retrospective cohort study. Consecutivepatients who underwent typical AFL catheter ablationwith either a gold-tip or CF-sensing catheter were enrolled.The procedural parameters obtained were: time to achievebidirectional block, time to terminate AFL, total duration of RFapplication, procedure duration, fluoroscopy time, acute reconnectionwithin 20 minutes following the last RF application,and procedural complications.Results: Of the 40 patients screened, 37 were included in thestudy. The procedural endpoint of bidirectional isthmus blockwas achieved in all patients. The use of gold-tip catheters wasassociated with a shorter length of time to achieve bidirectionalblock (median time: 20.0 minutes [interquartile range{IQR}: 12.0–28.0 minutes]) compared with a median time of36.0 minutes (IQR: 12.0–53.0 minutes; p=0.048) in the CFgroup. Furthermore, there was a trend toward reduced proceduralduration in favor of the gold-tip catheter (median goldtip:74.0 minutes [IQR: 57.0–84.0 minutes]; median CF: 85.0minutes [IQR: 57.0–107.0 minutes]; p=0.171). A greater requirementfor the use of long sheaths was observed in caseswhere the CF catheter was employed for the procedure (CF:11, 57.9 %; non-CF: 1, 5.6%; p=0.005).Conclusion: The time required to achieve bidirectional block,which is also reflected in the procedural time, was less whenusing a gold-tip catheter, and there was less need for the useof a long sheath. Further studies may be useful to evaluatethis finding.

Özet

Amaç: Radyofrekans ablasyonu (RFA) atriyumlardan kaynaklanan anormal kalp ritmi olan tipik atriyal flatterin (AFL) tedavisi için yüksek derecede başarılı bir işlemdir. Kavotriküspit istmusla (KTİ) ilişkili AFL’nin tedavisinde temas kuvveti (TK) kullanımının prosedürün süresi veya akut dönemde başarısına herhangi bir etkide bulunduğuna dair güçlü kanıtlar yoktur. Bu çalışmanın amacı AFL hastalarında TK’den yararlanmayan 4 mm’lik altın uçlu irigasyon kateteri ile TK’ye duyarlı kateteri akut dönem parametreleri açısından karşılaştırmaktı. Yöntemler: Bu bir geriye dönük kohort çalışmasıydı. Altın uçlu veya TK’ye duyarlı kateterle tipik AFL gerçekleştirilmiş ardışık hastalar çalışmaya alındı. İşleme ilişkin parametreler, iki yönlü blokun oluşmasına, AFL’yi sonlandırmaya kadar geçen zaman, toplam RF uygulama süresi, işlemin, floroskopinin uygulama süreleri, son RF uygulamasından sonraki 20 dakika içinde yeniden uygulama ve işlemim komplikasyonlarından ibaretti. Bulgular: İncelenen 40 hastanın 37’si çalışmaya alındı. Uygulamada son nokta hastaların tümünde iki yönlü istmus blokunun gerçekleşmiş olmasıydı. Altın uçlu kateterin kullanılmasıyla daha kısa sürede çift yönlü blok gerçekleşti (ortanca süre, 20.0 dakika [çeyrekler arası aralık {IQR}]: 12.0–28.0 dakika; TK grubunda ise ortanca süre, 36.0 dakika (IQR: 12.0–53.0 dakika; p=0.048). Ayrıca, altın uçlu kateter lehine işlem süresinde kısalma eğilimi mevcuttu (altın uç grubunda ortanca süre: 74.0 dakika [IQR: 57.0–84.0 dakika] iken TK grubunda ortanca süre: 85.0 dakika [IQR: 57.0–107.0 dakika]; p=0.171). Uygulamada daha uzun KF kateterine daha fazla gereksinim duyulmuştur (TK: 11, %57.9; altın uç: 1, %5.6; p=0.005). Sonuç: Altın uçlu kateter kullanıldığında işlem süresine de etki eden çift yönlü blok daha kısa sürede gerçekleştiği gibi uzun kateter kullanımına daha az gereksinim duyulmuştur. Bu bulguyu değerlendirmek için daha fazla çalışma gerçekleştirmek yararlı olabilir.
