Abstract

The most important sequel of acute rheumatic fever is mitral stenosis in long-term. The aim of the study is to determine left ventricular (LV) functions by tissue Doppler imaging (TDI) and strain/strain rate echocardiography (SE/SRE) in mitral stenosis patients who had no clinical signs of heart failure. Methods: Our study was designed as cross-sectional study. The study population consisted of 32 patients with isolated mitral stenosis and mitral valve area < 2.0 cm2 (Group 1) and 25 healthy control subjects (Group 2). In addition to standard echocardiographic methods, TDI and SE/SRE were performed to assess LV functions in all participants. Student’s t-test was used to compare continuous variables. Fisher- exact test was used to compare categorical variables. Results: Systolic myocardial velocity (Sm) were significantly lower in Group 1 than in Group 2 (6.0±1.4 cm/sec vs 7.9±1.8 cm/sec, p

Özet

Akut romatizmal ateşin uzun dönem en önemli sekeli mitral darlığıdır. Bu çalışmanın amacı, klinik olarak kalp yetersizliği bulguları olmayan mitral darlığı olan hastalarda, sol ventrikül (LV) fonksiyonlarının doku Doppler görüntüleme (TDI) ve strain/strain rate ekokardiyografi (SE/SRE) teknikleri ile değerlendirilmesidir. Yöntemler: Çalışmamız enine-kesitli olarak dizayn edildi. Çalışmamıza 32 izole mitral darlığı olan, mitral kapak alanı
