This study determined the prevalence and national prenatal detection rate of major congenital heart defects (mCHD) in twin pregnancies without twin-to-twin transfusion syndrome (TTTS)-associated CHD. The researchers analyzed data from Danish twin pregnancies between 2009 and 2018, where at least one fetus had a mCHD diagnosis pre- and/or postnatally. They found that the prevalence of mCHD in twins was 4.6 per 1,000 twin pregnancies, with higher rates in monochorionic twins. The national detection rate of mCHD in twin pregnancies was 68.3%. Cases with univentricular hearts had the highest detection rates, while certain anomalies had lower detection rates. Mothers of undetected mCHD cases had higher body mass index (BMI) than those with detected mCHD.
