🎯
Objective & Hypothesis:To evaluate right ventricular hypertrophy and diastolic function with echocardiography,a study was made on 21 children with pulmonary hypertension ( PHT ) (4,3 5,1 year).All patients had congenital heart diseases with left to right shunts.Results were compared to 20 normal children (4,1 4,2 year ).Interventricular septal thickness and right ventricular anterior wall thickness were significantly increased,revealing right ventricular hypertrophy.Echocardiographic diastolic filling parameters, isovolumic relaxation time ( IVRT ),E and A velocity,acceleration and deceleration time were measured.Corrected IVRT was significantly different between groups,which shows right ventricular filling abnormalities in children with PHT (patients with PHT:114 30 ms; normal subjects : 70 17 ms, p 0,001 ).

Abstract

To evaluate right ventricular hypertrophy and diastolic function with echocardiography,a study was made on 21 children with pulmonary hypertension ( PHT ) (4,3 5,1 year).All patients had congenital heart diseases with left to right shunts.Results were compared to 20 normal children (4,1 4,2 year ).Interventricular septal thickness and right ventricular anterior wall thickness were significantly increased,revealing right ventricular hypertrophy.Echocardiographic diastolic filling parameters, isovolumic relaxation time ( IVRT ),E and A velocity,acceleration and deceleration time were measured.Corrected IVRT was significantly different between groups,which shows right ventricular filling abnormalities in children with PHT (patients with PHT:114 30 ms; normal subjects : 70 17 ms, p 0,001 ). Patients had increased E velocity and decreased acceleration time;however A velocity, E /A ratio and deceleration time were not significantly different between groups.Tricuspid regurgitation (TR) was observed in 13 patients.We could not find typically relaxation pattern,which we expected in patients with RV hypertrophy.We suggest that this is because TR,which effects RV filling by increasing right atrial pressure.

Özet

Çalışmamızda pulmoner hipertansiyonlu ( PHT ) çocuklarda ekokardiyografik yöntemle sağ ventrikül hipertrofisinin ve sağ ventrikül diyastolik fonksiyonlarının değerlendirilmesi amaçlandı.Soldan sağa şantlı konjenital kalp hastalığı olan 21 PHT'lu çocuk (4,3 5,1 yıl ) ve 20 kontrol hastası ( 4,1 4,2) çalışıldı., PHT'lu hastalarda kontrol grubuna göre interventriküler septum ve sağ ventrikül ön duvar kalınlığının önemli derecede artmış olduğu gösterildi.Sağ ventrikül diyastolik fonksiyon parametrelerinden IVRTc hasta grubunda 114 30 ms, kontrol grubunda ise 70 17 ms bulundu (p 0,001) . Hasta grubunda E velositesi artmış, AcT süresi kısalmış bulunurken,A velositesi, E/A oranı DecT süresi yönünden iki grup arasında fark saptanmadı.Hasta grubunda 13 hastada triküspit yetmezliği saptandı. Çalışmamızda izovolemik relaksasyon zamanının hasta grubunda önemli oranda artmış bulunması sağ ventrikül relaksasyon paterninde bozulmanın başladığını göstermektedir.Bununla birlikte çalışmamızda olduğu gibi triküspit yetmezliğinin eşlik ettiği durumlarda belirgin sağ ventrikül hipertrofisine rağmen diyastolik fonksiyonlarda hipertrofide görülmesi beklenen tipik relaksasyon örneğinin görülemeyebileceği sonucuna vardı k.
