Abstract

Objective: An imbalance between parasympathetic and sympathetic tone is a main cause of neurally mediated reflex syncope (NMRS). These patients may be very symptomatic and the condition may require cardiac pacemaker implantation. Cardioneuroablation (CNA) is a relatively novel technique based on radiofrequency ablation of vagal ganglia that can be used in treatment of NMRS. The aim of this analysis was to compare potential role of CNA in patients with NMRS.?Methods: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, literature search was conducted using the keywords "cardioneuroablation," "vagal denervation," "reflex syncope," "vagal ablation," and "ganglionic plexi ablation." Retrieved citations were first screened independently by 2 reviewers for inclusion and exclusion criteria.Results: Freedom from syncope and freedom from prodrome were 100% and between 50% and 100%, respectively, in the studies. Ablation was performed via both atria in 3 studies; only left atrial approach was used in the remaining studies. There was no major complication related to the procedure reported.?Conclusion: Focused or extensive vagal ganglia ablation may be a potential alternative to pacemaker implantation in a carefully selected patient population. In contrast to pharmacological therapy and pacemaker implantation, ganglia ablation is designed to get to the root of the problem: disturbances in the intrinsic cardiac autonomic nervous system. This novel technique should be evaluated in large-scale, randomized, controlled trials.

Özet

Amaç: Parasempatik ve sempatik tonüs arasındaki denge bozukluğu nöral aracılı refleks senkobun (NARS) ana nedenlerinden biridir. Bu hastalar çok semptomlu olabilir ve durum kalp pili takılmasını gerektirebilir. Kardiyonöroablasyon (KNA) vagal gangliyonların radyofrekans kateter ablasyonuna dayanan ve NARS'li hastalarının tedavisinde kullanılabilen göreceli olarak yeni bir tekniktir. Bu çalışmada, NARS'li hastalarda KNA'nın rolü ile ilgili mevcut bilgiler karşılaştırıldı.Yöntemler: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) beyanına uygun olarak 'cardioneuroablation', 'vagal denervation', 'reflex syncope', 'vagal ablation' ve 'ganglionic plexi ablation' kelimeleri ile literatür taraması yapıldı. Tüm yayınlar dahil edilme ve dışlanma kriterleri açısından iki yorumcu tarafından bağımsız olarak değerlendirildi.Bulgular: Toplam beş gözlemsel çalışma ve beş olgu sunumu çalışmaya kabul edildi. Senkopsuz sağkalım %100 iken herhangi bir prodromsuz sağkalım %50 ile %100 arasında bulundu. Üç çalışmada her iki atriyumdan ablasyon uygulanırken iki çalışmada sol atriyum yaklaşımı kullanılmıştı. İşleme bağlı ciddi komplikasyon izlenmedi.Sonuç: Odaklanmış ya da geniş vagal ganliyon ablasyonu dikkatli seçilen hastalarda kalp pili takılmasına bir seçenek olabilir. Farmakolojik tedavi ve kalp pili takılmasından farklı olarak gangliyon ablasyonu problemin kökenini yani kalbin otonom sistemindeki bozukluğu hedeflemektedir. Bu yeni teknik geniş kapsamlı randomize çalışmalarda değerlendirilmelidir.
