Clinical aspects of prenatally detected congenital heart malformations and the yield of chromosomal microarray analysis

Abstract excerpt

OBJECTIVE: The yield of chromosomal microarray analysis (CMA) for prenatally detected congenital heart defects (CHD) is 6.6% to 19.2%. We evaluated the yield of CMA in cases of prenatally detected CHD in regard to specific clinical characteristics. METHODS: Data from 192 cases of CHD including type, clinical and familial background, workup performed during the pregnancy, and pregnancy outcomes were collected....
