Abstract
Uvod: Kateterska ablacija atrijalne fibrilacije (AF) je značajno efikasnija od antiaritmika u održavanju sinusnog ritma. Razvojem elektroanatomskih maping (EAM) sistema značajno je unapređen rezultat ablacije AF. Ciljevi: Analiza (1) izvodljivosti ablacije AF vođene EAM sistemom u našem centru i periproceduralnih komplikacija, (2) efekta ablacije AF na održavanje sinusnog ritma i kardiovaskularne (KV) događaje. Metodologija: Analizirano je 498 konsekutivnih bolesnika (životno doba 60 [IQR:52–66] god., 61.4% muškarci, 72.9% paroksizmalna AF) koji su podvrgnuti ablaciji AF uz upotrebu EAM sistema. Izvršena je široka antralna izolacija plućnih vena (sa/bez ablacije supstrata). Praćenje je vršeno 24h-Holterom nakon 1, 3, 6 meseci posle ablacije, a potom svakih 6 meseci. Registrovani su recidivi aritmije i KV događaji (kompozit: smrtnost, nefatalni moždani udar, nefatalni infarkt miokarda, veliko krvarenje i/ili srčana insuficijencija) posle ablacije. Rezultati: Ukupno je izvršena 721 proce...dura ablacije. Kasni recidiv aritmije je imalo 18.7% bolesnika tokom praćenja od 30 ± 17 meseci posle poslednje procedure. Nezavisni prediktori pojave kasnih recidiva su bili: pojava ranog recidiva <3 meseca (HR 6.75) i dimenzija leve pretkomore (HR 1.06 za svaki 1 mm). Stopa major komplikacija je bila 4.9%, a prediktori njihove pojave su: ishemijska bolest srca (OR 3.11) i krivulja učenja (OR 0.65 na svakih 180 izvršenih ablacija). Pojava KV događaja nakon ablacije je registrovana kod 4% bolesnika (0.28% smrtni ishod i 0.28% moždani udar). Nezavisni prediktori KV događaja bili su: kasni recidiv aritmije (HR 3.29) i veća leva pretkomora (HR 1.11 za svaki 1 mm). Zaključak: ablacija AF vođena EAM sistemima je efikasna i bezbedna terapijska opcija za održavanje sinusnog ritma. Sinusni ritam posle ablacije povezan je sa povoljnim KV ishodom.

maintenance of sinus rhythm. Development of electroanatomic mapping (EAM) systems significantly improved the result of AF ablation. Objectives: the analysis of (1) feasibility of AF ablation guided by EAM in our centre and periprocedural complications, (2) efects of ablation on rhythm control and cardiovascular outcomes. Methods: We analyzed 498 consecutive patients (median age 60 [IQR:52–66] years, 61.4% males, 72.9% paroxysmal AF) who underwent AF ablation guided by EAM. In all patients wide antral pulmonary vein isolation (with/without substrat ablation) was completed. Follow-up consisted of 24h/Holter-recordings at 1, 3, 6 months after ablation, and thereafter every 6 months. We registered all the arrhythmia recurrences and CV events (composit of fatal outcome, nonfatal stroke, nonfatal myocardial infarction, major bleeding and/or heart failure) after ablation. Results: A total of 721 ablation procedure were performed. The late arrhytmia recurrence was detected in 18.7% of patients... during the follow-up of 30 ± 17 months after last procedure. Multivariate risk factors for the late recurrence are: the early recurrence within the 3 months post-ablation (HR 6.75) and left atrial diameter (HR 1.06 for each 1 mm). The rate of major complications was 4.9%, and risk factors for their occurrence are: ischemic heart disease (OR 3.11) and learning curve (OR 0.65 for each 180 consecutive procedures). The CV events post-ablation was noted in 4% of patients (lethal outcome 0.28%, nonfatal stroke 0.28%). Multivariate risk factors for CV events are: the late arrhythmia recurrence (HR 3.29) and dilated left atrium (HR 1.11 for each 1 mm). Conclusion: AF ablation guided by an EAM system is efficient and safe treatment option for maintenance of sinus rhythm. A sinus rhythm after ablation is related to better CV outcome(s).
