Abstract

Objectives: Mitral valve pressure gradient measured by echocardiography is a very useful method for the evaluation of mitral valve disease. The standard method is based on the calculation of mean mitral valve pressure gradient with the use of the modified Bernoulli equation, which includes manual drawing of the border of Doppler signal. Recently, two new methods have been described by Devlin M et al. and Yang SS, respectively. This study aimed to compare the results of the standard method with those of the new methods.Study design: We prospectively studied 78 patients (55 women, 23 men; mean age 43±14 years; range 17 to 78 years) with mitral valve gradient either due to mitral stenosis or mitral valve replacement. Atrial fibrillation was present in 31 patients. The mean mitral valve gradient was measured using the standard method. As for the new methods, measurements of the mean mitral valve gradient were made without manual drawing of the border of Doppler signal and using the formulas which included the peak and trough velocities. Transmitral gradient was also obtained by cardiac catheterization in 14 patients. Results: The mean transmitral pressure gradients were 9.2±5.7 mmHg, 9.4±6.2 mmHg, and 10.6±6.6 mmHg by the standard method, the first, and the second methods, respectively. The new methods were in good correlation with the standard method (for both methods, r=0.98, p

Özet

Amaç: Ekokardiyografik olarak ölçülen transmitral basınç farkı mitral kapak hastalarının kapak fonksiyonlarını değerlendirmede kullanılan önemli bir yöntemdir. Geleneksel yöntemde modifiye Bernoulli eşitliğinden yararlanılarak elde edilen ortalama transmitral basınç farkı, pulse Doppler sinyal sınırlarının elle çizilmesine dayanır. Son zamanlarda, bu ölçüm için sırasıyla Devlin M ve ark. ve Yang SS tarafından daha kolay iki yöntem tanımlanmıştır. Bu çalışmada geleneksel yöntemle yeni yöntemlerin karşılaştırılması amaçlandı.Çalışma planı: Mitral darlığı veya mitral kapak replasmanı nedeniyle mitral kapak üzerinde basınç farkı oluşan 78 hasta (55 kadın, 23 erkek; ort. yaş 43±14; dağılım 17-78) prospektif olarak incelendi. Hastaların 31’inde atriyal fibrilasyon vardı. Tüm hastalarda geleneksel yöntemle ortalama transmitral basınç farkı bulundu. Yeni yöntemler için, pulse Doppler akım trasesinin sınırları elle çizilmeden, sadece tepe ve orta hızlar ölçüldü, tanımlanan formüller yardımıyla ortalama transmitral basınç farkı hesaplandı. Transmitral basınç farkı ayrıca 14 hastada kardiyak kateterizasyon sırasında da ölçüldü. Bulgular: Standart yöntemle, birinci ve ikinci yöntemle ölçülen ortalama transmitral basınç farkları sırasıyla 9.2±5.7 mmHg, 9.4±6.2 mmHg ve 10.6±6.6 mmHg bulundu. Yeni yöntemlerin standart yöntemle iyi bir korelasyon gösterdiği görüldü (her iki yöntem için, r=0.98, p
