Fetal echocardiography using transvaginal and transabdominal probes during the first period of pregnancy: A comparative study

Abstract
The authors compare the diagnostic possibilities of fetal transabdominal echocardiography versus transvaginal echocardiography. A larger diagnostic capacity is verified in different gestation ages with transvaginal probe between the 11th and 14th week of gestation. The results are emphasized by colour Doppler.
