Özet
Mitral kapak hastalıklarının tedavisinde mitral yetersizliğinin non-invazif değerlendirilmesi önemlidir. Bu çalışmanın amacı kronik romatizmal mitral yetersizlikti çocuklarda regürgitan fraksiyonu ölçmek ve anjiografik ve sintigrafik metodlarla karşılaştırmaktır. İzole kronik mitral yetersizliği olan 18 hasta ( ortalama yaş:12.69±3.47) ekokardiyografi ile değerlendirildi. Tüm hastalar ARF tanısı için modifiye Jones kriterlerine göre değerlendirildiler. Mitral regürgitan volüm (RV) Doppler ekokardiyografi ile LVIV ve LVOV farkından Fisher metodu ile hesaplandı. Regürgitan fraksiyon (RF) RV/LVIV formülü ile hesaplandı. Ortalama RF Doppler ekokardiyografi ile % 46.3±14.93, MUCA metodu ile % 50.05±17.40 ve anjiografik metodla % 61.23±16.2 bulundu. Doppler ekokardiyografi ile hesaplanan RF hem kardiyak kateterizasyon ( r= 0.96) hem de sintigrafik metod ( r=0.80) ile korele bulundu. Sonuç olarak,bu çalışma romatizmal mitral yetersizlikti hastaların kantitatif değerlendirilmesinde Doppler ekokardiyografinin yeterli olduğunu göstermiştir.
Abstract
Non-invasive assessment of the severity of mitral regurgitation is important in the management of patients with mitral valvular disease. The aim of this study was to compare regurgitant fraction measurements obtained using echocardiographic, angiographie and scintigraphic methods in children with chronic rheumatic mitral regurgitation. Eighteen patients (mean age 12.69±3.47) with isolated chronic mitral regurgitation were evaluated by echocardiography. All patients fulfilled the modified Jones criteria for diagnosis of ARF. Mitral regurgitant volume (RV) was calculated using the Doppler echocardiographic method as the difference between LVIV (Left ventricular inflow volume) and LVOVf Left ventricular outflow volume) determined by the Fisher method. Regurgitant fraction (RF) was calculated as RV/LVIV. The mean RF measured by Doppler echocardiography was 46.31 ±14.93%. The mean RF measured by angiography and Multigated Radionuclide Angiography (MUCA) methods were 50.05±17.40% and 61.23±16.62%, respectively. Comparisons showed that RF calculated by Doppler echocardiography correlated with RF determined by both cardiac catheterization (r=0.96) and scintigraphy (r=0.80). In conclusion, this study demonstrates that Doppler echocardiography is capable of quantitatively evaluating these patients with rheumatic mitral regurgitation.
