Twenty\u2010six CNVs were identified in 18 fetuses (34.6%), 15 benign CNVs were detected in 11 (21.2%) fetuses, and 8 pathogenic CNVs were detected in 6 (11.5%) fetuses. After excluding 2 fetuses with 22q11.2 deletion syndrome, the rate of pathogenic CNVs was 7.7%. The proportion of variants of unknown significance was 5.8% (3\/52). In five cases, additional malformations were detected after birth or abortion, and one case had a prenatal isolated VSD. The detection rate of pathogenic CNVs in nonisolated VSDs was nonsignificantly higher than that in prenatal or postnatal isolated VSDs (4.5%, 1\/22 vs 16.7%, 5\/30, <jats:italic>P<\/jats:italic>\u2009=\u20090.226; 0\/21 vs 19.4%, 6\/31, <jats:italic>P<\/jats:italic>\u2009=\u20090.07).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The results demonstrated the value of chromosomal microarray analysis in the prenatal diagnosis of VSDs.
