In utero thickening of the chordae tendinae. A cause of intracardiac echogenic foci.

Abstract

Asymptomatic hyperechoic foci were noted within the left cardiac ventricular chamber on the prenatal sonograms of 26 patients between 16 and 20 weeks of gestation. Their range of occurrence, the prenatal follow-up in 12 patients and postnatal echocardiograms in six patients, indicate a clinically insignificant congenital anomaly associated with the chordae tendinae.
