Small echogenic areas in the fetal heart are known as the golf ball phenomenon. These structures are considered by some to be a marker for chromosomal anomalies.
AIM : To prospectively study the relationship of echogenic intracardiac structures and chromosomal aberrations.
METHODS : Over a 15 month period (6/96-9/97) 4500 unselected fetuses between 16-31 weeks were screened for malformations; in each case echogenic intracardiac structures were sought.
RESULTS: In 77 cases (1.17%) single or multiple echogenic punctate intracardiac structures could be diagnosed. In 60 fetuses (78%) chromosome analysis was performed. Two (3.3%) had chromosomal abnormalities–trisomy 21 and 45.XO/46.XX.
