Abstract

OBJECTIVE: There is no data related to right ventricular functions in mild mitral stenosis patients with normal pulmonary pressure. Therefore, in the present study we investigated right wntricular functions in mild mitral stenosis patints who had visually normal right ventricul by tissue Doppler imaging.METHODS: The study population consisted of 42 rhuematic mild mitral stenosis patients and 31 age-sex matched controls. All patients underwent conventional echocardiography and tissue Doppler imaging. Isovolumetric myocardial accelearation, myocardial performance index and peak sistolic velocities were calculated from the tissue Doppler parameters. RESULTS: The study grops were comparable regarding age, sex, systolic pulmonary artery pressure, systolic-diastolic blood pressure and heart rate. When compared to the control group patients with mitral stenosis had significabtly lower values of isovolumetric myocardial acceleration p: 0,001 , myocardial performance index p: 0,014 and peak systolic velocity p: 0,001 . Within the tisstue Doppler parameters, isovolumetric myocardial acceleration was the most closely correlated parameter with the mitral valve area r: 0.59; p: 0,0001 CONCLUSION: Rheumatic mild mitral stenosis patients with visually normal right ventricle had impaired right ventricular function assessed by tissue Doppler imaging. This impaired function might be related to the rheumatismal myocardial involvement rather than abnormalities in the pulmonary vasculatories.

Romatizmal Hafif Mitral KapakTutulumunda Sağ Ventrikül Fonksiyonlarının Doku Doppler Ekokardiyografi ile Değerlendirilmesi

Abstract

AMAÇ: Romatiznal hafif mitral darlıklı hastalarda, pulmoner arter basıncı normalken sağ ventrikül fonksiyonları ile ilgili veri yoktur. Biz bu çalışmamızda görsel ve boyutsal olarak normal sağ ventriküle sahip hafif mitral darlığı hastalarında sağ ventrikül fonksiyonlarını doku Doppler ile değerlendirmeyi planladıkYÖNTEMLER: Çalışmaya 42 romatizmal hafif mitral darlıklı hasta ve 31 yaş ve cinsiyet eşleşmiş kontrol grubu alındı. Hastalara konvensiyonel ve doku Doppler ekokrdiyografi yapıldı. Doku Doppler parametlerinden izovolümetrik miyokardiyal akselarasyon, miyokard performans indeksi ve tepe sistolik velosite hesaplandı. BULGULAR: Her iki grupta yaş ortalaması, cinsiyet, sistolik pulmoner arter basıcı sistolik ve diyastolik kan basıncı ve kalp hızı değerleri benzerdi. Doku Doppler parametrelerinden izovolümetrik miyokardiyal akselarasyon p: 0,001 , miyokard performans indeksi p: 0,014 ve tepe sistolik velosite p: 0,001 anlamlı olarak hasta grubunda düşük saptandı. İzovolümetrik miyokardiyal akselarasyon doku Doppler parametrelerinden arasında mitral kapak alanı ile en iyi korele olan paramatre olarak bulundu r: 0.59; p: 0,0001 SONUÇ: Görsel ve boyutsal olarak normal sağ ventriküle sahip romatizmal hafif mitral darlığı hastalarında doku Doopler ile değerlendirilen sağ ventrikül fonksiyonları bozulmuştur. Sağ ventrikül fonksiyonlarındaki bu bozukluk pulmoner vaskülatürdeki değişikliklerden çok sağ ventrikülün romatizmal tutulumuna bağlı olabilir.
