Why the study?
To demonstrate the adjunctive use of SlowflowHD to improve the capability to prenatally diagnose congenital heart anomalies at 11-13+6 weeks of gestation.
Does SlowflowHD improve the capability to prenatally diagnose congenital heart anomalies at 11-13+6 weeks of gestation?
Does SlowflowHD improve the capability to prenatally diagnose congenital heart anomalies at 11-13+6 weeks of gestation?
SlowflowHD Doppler ultrasound enables detailed visualization of fetal cardiac microvasculature, allowing for the early first-trimester diagnosis of complex congenital heart anomalies like TAPVR and truncus arteriosus.
May support first-trimester complex CHD detection with SlowflowHD; hypothesis-generating and should not yet change practice.
