Impact of Maternal Obesity and Maternal Overweight on the Detection Rate of Fetal Heart Defects and the Image Quality of Prenatal Echocardiography

The prenatal detection of fetal AVSD, DORV, TOF and D-TGA was also satisfactory in overweight and obese patients, but image quality substantially decreases with an increasing maternal BMI. If there is a BMI-associated difference in the detection rate, it probably will not exceed 20%.
