Abstract

Objective: To assess embryonic and fetal cardiac growth and development using transvaginal 2-dimensional sonography before 12 weeks of gestation.

Methods: Transvaginal scans for first-trimester dating were performed for 131 normal fetuses at 8-11 + 6 weeks of gestation. The basal-apical length (BAL), transverse length (TL), cardiac circumference (ECC), embryonic cardiac area (ECA), global sphericity index (GSI), and cardio-thoracic area ratio (CTAR) were able to be obtained in 105 normal embryos and fetuses.

Results: Nomograms for several cardiac parameters including BAL, TL, ECC, ECA, GSI, and CTAR were constructed. BAL, TL, ECC, and ECA increased curvilinearly with advancing gestation (R² = 0.97406, 0.980396, 0.978359, and 0.920705, respectively, P < .001). GSI (mean, 1.14; SD, 0.10) and CTAR (mean, 15.7%; SD, 3.3%) values were constant at 8-11 + 6 weeks of gestation. There were significant curvilinear correlations between BAL, TL, ECC, and ECA, and crown-rump length (CRL) (R² = 0.975976, 0.983482, 0.980673, and 0.929936, respectively, P < .001). GSI and CTAR values were not changed with the increase of CRL during this period.

Conclusion: Our results provide nomograms for several cardiac parameters which may improve the understanding of embryonic and fetal cardiac growth and development prior to 12 weeks of gestation.

期刊介绍： The Journal of Ultrasound in Medicine (JUM) is dedicated to the rapid, accurate publication of original articles dealing with all aspects of medical ultrasound, particularly its direct application to patient care but also relevant basic science, advances in instrumentation, and biological effects. The journal is an official publication of the American Institute of Ultrasound in Medicine and publishes articles in a variety of categories, including Original Research papers, Review Articles, Pictorial Essays, Technical Innovations, Case Series, Letters to the Editor, and more, from an international bevy of countries in a continual effort to showcase and promote advances in the ultrasound community. Represented through these efforts are a wide variety of disciplines of ultrasound, including, but not limited to: -Basic Science- Breast Ultrasound- Contrast-Enhanced Ultrasound- Dermatology- Echocardiography- Elastography- Emergency Medicine- Fetal Echocardiography- Gastrointestinal Ultrasound- General and Abdominal Ultrasound- Genitourinary Ultrasound- Gynecologic Ultrasound- Head and Neck Ultrasound- High Frequency Clinical and Preclinical Imaging- Interventional-Intraoperative Ultrasound- Musculoskeletal Ultrasound- Neurosonology- Obstetric Ultrasound- Ophthalmologic Ultrasound- Pediatric Ultrasound- Point-of-Care Ultrasound- Public Policy- Superficial Structures- Therapeutic Ultrasound- Ultrasound Education- Ultrasound in Global Health- Urologic Ultrasound- Vascular Ultrasound
