Abstract

Objective: Low threshold characteristics and mechanical stability are important features of an ideal pacing lead, especially for children. We report our experience and medium-term results with a steroid-eluting, active-fixation ventricular lead in children.Methods: Telectronics Accufix II DEC model 033-212 ventricular leads were implanted in 21 patients. Eighteen patients (11 male / 7 female; 10.6 ± 4.0 years), who were followed for a mean period of 6.47 ± 1.13 years were included in the study.Results: Pacemaker mode was DDDR in three patients, and VVIR in the remaining 15 patients. Mean threshold value was 0.5 volts at implant, which increased to 0.7 volts in the first month (p>0.05). It remained stable (0.62-0.78 V) until 5.5 years (p>0.05), increased significantly at 5.5 years (0.99 ± 0.63 V at 5.5 years, p

Özet

Amaç: Düşük uyarı eşiği ve mekanik stabilite ideal kalp pili elektrodunun özellikle çocuklarda önemli özelliklerindendir. Aktif sabitlenen ve steroid salgılayan ventriküler elektrodların çocuklarda kullanımı ile ilgili orta-dönem izlem sonuçlarımızı sunuyoruz. Yöntemler: Telectronics Accufix II DEC, 033-212 model ventriküler elektrodlar 21 hastaya uygulandı. Ortalama 6.47±1.13 yıl izlenen 18 hasta (11erkek/7 kız; ortalama 10.6±4.0 yaş) incelemeye alındı. Bulgular: Üç hastada kalıcı kalp pili DDDR, diğerlerinde (15 hasta) VVIR modunda çalışıyordu. Uygulama sırasındaki ortalama uyarı eşiği 0.5 volt iken ilk ayın sonunda 0.7 volta yükseldi (p>0.05). Eşik değeri 5.5 yıl 0.62-0.78V aralığında stabil seyrettikten sonra ortalama 0.99±0.63V yükseldi ve başlangıç değerlerine göre anlamlı olarak yüksek seyretti (p0.05). On üç hastada pil ömrü ≥ 4 yılda tükendi. Kalıcı kalp pili değiştirilen bütün hastalarda (11 hasta) elektrodlar yerinde bırakıldı. Sonuç: Aktif sabitlenen ve steroid salgılayan ventriküler elektrodlar uzun ömürlüdür ve düşük uyarı eşiklerinin olmaması daha düşük voltaj çıkışı ile çalışmalarını sağlamaktadır. Bu özellikler çocukların kalp pili tedavisinde avantajlı olabilir.
