FETAL ECHOCARDIOGRAPHY: STATE-OF THE ART - advanced course. London, 12 May, 2018. Many fetal cardiac anomalies are difficult for detection, even for experienced ultrasound specialists. Subaortic VSDs in all three cases demonstrated by the video clip were undiagnosed on primary scan. Our advanced Fetal Echo course was created for doctors and ultrasound practitioners. The course will help them to improve their abilities to diagnose fetal cardiac anomalies. The core elements of the course are videos of different congenital heart defects (CHD). We will reveal all our tips and tricks witch are essential for diagnosis of CHD. Regarding the video itself: every effort must be done to detect subaortic VSD prenatally. It is technically challenging. This type of VSD is strongly associated with chromosomal anomalies (T21, T18, T13, 22q del and other) and genetic syndromes. The majority of those VSDs will require cardiac surgery for closure. Please learn how to diagnose them.
