Gebelikte Speckle Tracking Ekokardiyografisi ile Değerlendirilen Anne Kalbinin Mekanik Fonksiyonlarının Değişimi

Giriş: Bu çalışmanın amacı sağlıklı gebelerde, gebelik süresince ve sonrasında sol ventrikül fonksiyonlarındaki değişimi “iki boyutlu speckle tracking ekokardiyografi (STE)” yöntemi ile araştırmaktır. Hastalar ve Yöntem: Çalışmaya 86 sağlıklı gebe dahil edilmiş ve gebeliğin birinci trimester 8-12 hafta, ikinci trimester 20-24 hafta, üçüncü trimester 32-36 hafta ve postpartum 10-14. haftada 2 boyutlu ekokardiyografi ile kayıtları alınmıştır. Sol ventrikül global longitüdinal strain (SV-GLS), sol ventrikül global radiyal strain (SV-GRS), sol ventrikül global sirkumferansiyel strain (SV-GCS) değerleri not edilmiştir. Bulgular: SV-GLS birinci trimester için -%21.0 ± 2.1; ikinci. trimester için -%19.9 ± 1.8; üçüncü trimester için -%18.2 ± 2.1; postpartum -%19.1 ± 1.4, p< 0.001). SV-GCS gebelik boyunca anlamlı olarak azalırken (p= 0.033), post partum dönemde 1.ci trimesterde bulunan değerlerine yükseldi. SV-GRS değerlerinde gebelik boyunca değişiklikler istatistiksel olarak anlamlı bulunmadı (p= 0.103). Sonuç: Bu çalışmada STE ile değerlendirilen, SV-GLS ve SV-GCS ile mekanik fonksiyonlarının anlamlı bir şekilde değiştiğini ve SV-GRS’de bir değişim olmadığını saptadık.

Alteration of Pregnant Women Heart Mechanics Assessed by Speckle Tracking Echocardiography During Pregnancy

Introduction: The purpose of this study was to evaluate left ventricular myocardial mechanics using 2-dimensional speckle tracking echocardiography (2D-STE) during normal, uncomplicated pregancy and postpartum term. Patients and Methods: In this prospective, longitudinal study, 86 healthy pregnant women who underwent serial 2 dimensional echocardiographic evaluation during each trimester (trimester one 8-12 weeks; trimester two 20-24 weeks, trimester three 32-36 weeks, and postpartum 10-14 weeks). Two-dimensional STE was performed to measure global left ventricular longitudinal, circumferential, and radial strain (GLS, GCS, and GRS, respectively). Results: GLS showed a decrease during pregnancy (for first trimester 21.0 ± 2.1%; for second trimester 19.9 ± 1.8%; for third trimester 18.2 ± 2.1; for postpartum 19.1 ± 1.4, p< 0.001). GCS was significantly reduced during pregnancy (p= 0.033) and peaked as the same value in the first trimester. GRS remained unchanged throughout the pregnancy and labor (p= 0.033). Conclusion: This study gives normal ranges of 2D indices in pregnancy. 2D STE demonstrated that LV longitudinal and circumferantial strain are significantly reduced, whereas radial strain remained unchanged.
