Abstract

The main reasons for traditional right ventricle apical pacing were first, the ease of implantation and second, the stability of passive-fixation leads in the apical trabeculae. However, apart from some specific diseases like hypertrophic cardiomyopathy, apical pacing often results in substantial functional, hemodynamic, electrical, and structural changes as previously demonstrated in many studies. Only in recent years, interest in the use of alternate pacing sites has developed. Right ventricular outflow tract is the preferred site of pacing because of its potential advantages such as ease of application, better hemodynamics, synchronous activation, less myocardial perfusion defects than apical pacing. The present review article comprehensively discusses this novel technique in terms of its beneficial effects compared to apical pacing and as an alternative method for biventricular pacing.

Özet

Kalıcı kalp pilinde elektrod yerleşimi için seçilen noktanın sağ ventrikül apeksi olması, elektrodun kolayca yerleştirilebilmesi ve yerinden oynamasının zorluğu gibi faktörlerdir. Apikal pacing, gerçekte yukarıdan aşağıya olan normal uyarı ekseninin aksine aşağıdan yukarıya doğru aktivasyon sağlayarak, ventrikülleri fizyolojik olmayan bir yolla uyarmaktadır. Apikal pacing’in fizyolojik olmamasından dolayı, senkronize ve fizyolojik uyarı sağlama gayesiyle sağ ventrikül çıkış yolu son yıllarda araştırılan ve tercih edilen nokta haline gelmiştir. Septal ileti yollarına yakın bu uygulamayla ventriküllerin normal uyarıda olduğu gibi daha senkron kasılacağı, kalp debisini artıracağı, apikal pacing ile bozulduğu saptanan mikrovasküler dolaşım yatağındaki dengesizliğin düzeleceği iddia edilmektedir. Ayrıca, koroner sinüse sol ventrikül elektrodu herhangi bir sebeple yerleştirilemeyen, resenkronizasyon işlemi uygulanacak kalp yetersizliği olan hastalarda, tek başına ya da bifokal alternatif uygulama olarak önerilmektedir. Bu derlemede son zamanlarda çok sık tartışılan bu uygulama ile ilgili kişisel deneyim ve yurt dışı literatür bilgisi aktarılması hedeflenmiştir.
