Feasibility and Accuracy of Early Fetal Echocardiography Performed at 13-13 Weeks in a Population with Low and High Body Mass Index: a Prospective Study.

Purpose: The earlier the detection and diagnosis of congenital heart diseases (CHD), the greater the clinical benefit; however, early fetal cardiac examination can be a challenge. The aim of our study is to demonstrate that the fetal cardiac examination at 13-13 weeks can be as adequately assessed as the examination performed at 16 weeks in patients with low and high body mass index (BMI).

Methods: The study was a prospective observational cohort study.
