Abstract

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.

Gebelikte Speckle Tracking Ekokardiyografisi ile Değerlendirilen Anne Kalbinin Mekanik Fonksiyonlarının Değişimi

Abstract

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.
