Diagnosis of congenital mitral and aortic stenosis from the fetal electrocardiogram.

A case of congenital mitral and aortic stenosis diagnosed from the fetal electrocardiogram (FECG) during labor is presented. Cardiologic work-up and autopsy findings in the neonate confirmed the diagnosis. This is the first case in which prenatal diagnosis of a specific anatomical lesion of the heart was made from the FECG and confirmed clinically as well as at autopsy.
