Transvaginal SlowflowHD for embryonic and fetal hearts: human cardiac development in first trimester of pregnancy.

This article discusses the use of transvaginal SlowflowHD imaging technology to examine the development of embryonic and fetal hearts in the first trimester of pregnancy. The study found that by the 11th week of gestation, all major structures of the heart had developed. The article also mentions previous studies that used older technology to visualize cardiac structures, but the quality of the images was poor. The authors conclude that transvaginal SlowflowHD imaging provides a high-resolution and sensitive method for assessing cardiac structures in early pregnancy. The use of SlowflowHD has the potential to diagnose congenital heart anomalies and provide valuable diagnostic information on various heart conditions. However, it cannot determine flow direction and velocity, and further research is needed to explore its potential role in early fetal cardiac diagnosis. [Extracted from the article]
