Abstract

Objectives: Prolonged QRS duration is associated with mechanical dyssynchrony. Ischemic mitral regurgitation (MR) results from geometric changes in left ventricular (LV) shape, which also causes mechanical dyssynchrony. The aim of this study was to define the correlation of QRS duration with echocardiographic parameters reflecting LV function, shape, and mitral deformation in patients with ischemic MR. Study design: The study included 29 patients (19 males, 10 females; mean age 64±3 years) who had at least moderate ischemic MR and a history of myocardial infarction or coronary revascularization. All the patients underwent echocardiography where LV ejection fraction, LV volumes, effective regurgitant orifice, tethering distance, tethering area, end-systolic sphericity index, and pulmonary artery pressures were measured. The patients were assessed in two groups formed based on the cutoff value of 120 ms for QRS duration. Results: The mean MR severity was 2.8±0.8. QRS duration was

Özet

Amaç: QRS süresinin uzaması, sol ventrikül (SV) mekanik senkronizasyon bozukluğunun bir göstergesidir. İskemik mitral yetersizlik (MY), mekanik senkronizasyon bozukluğuna da yol açan sol ventrikül geometrisinin bozulmasından kaynaklanır. Bu çalışmada, sol ventrikül sistolik fonksiyonlarını, geometrisini ve mitral aparat deformasyonunu gösteren ekokardiyografik parametrelerin QRS süresi ile ilişkisi araştırıldı.Ça­lış­ma pla­nı: Çalışmaya, en az orta derecede iskemik mitral yetersizliği ve miyokard infarktüsü veya koroner revaskülarizasyon öyküsü olan 29 hasta (19 erkek, 10 kadın; ort. yaş 64±3) alındı. Tüm hastalara yapılan ekokardiyografik incelemede SV ejeksiyon fraksiyonu, SV hacimleri, efektif regürjitan orifis, tethering mesafesi, tethering alanı, sistol sonu küresellik indeksi ve pulmoner arter basınçları ölçüldü. Hastalar, QRS süresi için kesim değeri 120 msn alınarak iki grupta değerlendirildi.Bul­gu­lar: Ortalama MY derecesi 2.8±0.8 idi. QRS süresi 19 hastada 120 msn’den düşük, 10 hastada ise ≥120 msn bulundu. Uzamış QRS süresine (≥120 msn) anlamlı derecede düşük SV ejeksiyon fraksiyonu ve yüksek SV hacimleri ve mitral kapağı deformasyon indeksleri eşlik etmekteydi. QRS süresi şu parametrelerle yakın ilişki gösterdi: SV ejeksiyon fraksiyonu (r=-0.62, p
