Abstract

Previous studies have shown improvement in left ventricular function and development of the reverse remodeling in left ventricle and left atrium after cardiac resynchronization therapy (CRT). The aim of this study was to investigate the effect of CRT on left atrial appendage function and pulmonary venous flow pattern. Eighteen patients with systolic heart failure and complete left bundle-branch block underwent implantation of biventricular pacemaker devices. In order to follow changes in left atrial appendage, transthoracic and transesophageal echocardiographic examinations were performed one week before, and repeated one and six months after pacemaker implantation.CRT resulted with significant clinical improvement and decrease in NYHA functional class in 17 patients (94%). Maximum and minimum areas of left atrial appendage (LAAmax and LAAmin) decreased, with a concomitant increase in LAA ejection fraction. [LAAmax: from 4.6 ± 2 cm2 to 4.2 ± 1.8 cm2 at the 1st (p

Özet

Kardiyak resenkronizasyon tedavisinin (KRT) sol ventrikül ve sol atriyumda "reverse remodeling" gelişmesine sol ventrikül sistolik fonksiyonunda iyileşmeye yol açtığı değişik çalışmalarda ortaya konmuştur. Bu çalışmanın amacı, KRT'nin sol atriyal apendiks fonksiyonu ve pulmoner ven akım paterni üzerine olan etkisini araştırmaktır. Sol ventrikül sistolik fonksiyon bozukluğu bulunan ve komplet sol dal bloklu 18 dilate kardiyomiyopatili hastaya biventriküler pacemaker implantasyonu uygulandı. Sol atriyal apendiks ve pulmoner ven akım paternindeki değişiklikleri değerlendirmek amacıyla pacemaker implantasyonundan bir hafta önce ve implantasyondan 1 ve 6 ay sonra transtorasik ve transözofajiyal ekokardiyografik incelemeler yapıldı. KRT sonrası hastaların 17'sinde (%94) anlamlı klinik iyileşme ve NYHA fonksiyonel kapasitelerinde artış gözlendi. Sol atriyal apendiks (SAA) ejeksiyon fraksiyon artışı ile birlikte sol atriyal apendiks maksimum ve minimum (SAAmax, SAAmin) alanlarında anlamlı küçülme saptandı [SAAmax: 4.6 ± 2cm2 den 1. ayda 4.2 ± 1.8 cm2'ye (p
