Characteristics of fetal conotruncal heart anomalies

Abstract

examined. Pregnancy outcomes and neonatal survival rates were evaluated. Results: A total of 396 congenital heart diseases were examined. CTA was diagnosed in 102 (25.8%) of the patients. Ninety-nine patients with available data were analyzed. A total of 33 (33.3%) patients were diagnosed with TOF, 30 (30.3%) with DORV, 16 (16.2%) with TA, 16 (16.2%) with TGA, and 4 (4%) with IIA-B. CTA was an isolated anomaly in 28 (28.3%) of the patients. The other patients had one or more accompanying cardiac/extracardiac anomalies. The prenatal invasive diagnostic was examined in 40 (40.4%) of the patients, and chromosomal anomalies were detected in 16 (40%) of them. In 18 (18.4%) of the patients, pregnancy was terminated at the request of the parents. Intrauterine demise occurred in 4 (4.9%) pregnancies that were not terminated, and neonatal death occurred in 26 (32.1%) of the newborns. Conclusions: The presence of additional cardiac, extracardiac, and genetic abnormalities are common in CTAs and are associated with adverse outcomes.
