ECHOGENIC FOCI

Not to be a downer but I thought this information was helpful. Doing some further research online I found that since I don't have any other risk factors I shouldn't worry too much.

ECHOGENIC FOCI
Prevalence
Echogenic foci in the heart are found in about 4% of pregnancies and in 12% of fetuses with trisomy 21.

Etiology
Histological studies have shown these foci to be due to mineralization within a papillary muscle.

Diagnosis
Echogenic foci are detected in the four-chamber view of the heart. In about 95% of cases, they are located in the left ventricle and in 5% in the right ventricle; in 98% they are unilateral and 2% bilateral. Ventricular function is normal and the atrioventricular valves are competent.

Prognosis
Echogenic foci are usually of no pathological significance and, in more than 90% of cases, they resolve by the third trimester of pregnancy. However, they are sometimes associated with cardiac defects and chromosomal abnormalities. For isolated hyperechogenic foci, the risk for trisomy 21 may be three times the background maternal age- and gestation-related risk (see Appendix I).
