Developmental Changes of the Coronary Sinus Between the First and Second Trimesters

Objective To assess the coronary sinus (CS) presence, size, and CS to atrial ratio (CS/A) in the first trimester (FT) compared with the second trimester (ST). Methods In this IRB‐approved retrospective study, fetuses with adequate FT cardiac sweeps and normal ST hearts were included. Maternal and fe...

Description
Summary:Objective To assess the coronary sinus (CS) presence, size, and CS to atrial ratio (CS/A) in the first trimester (FT) compared with the second trimester (ST). Methods In this IRB‐approved retrospective study, fetuses with adequate FT cardiac sweeps and normal ST hearts were included. Maternal and fetal characteristics were obtained. CS and atrial diameters were measured by a single sonologist. The CS/A ratio was compared between FT and ST. Linear regression assessed the relationship between biparietal diameter (BPD) and CS and atrial diameters. Statistical significance was set at P
