@entity4263 ( @entity4263 ) is an uncommon @entity299 characterized by the atria connecting with the anatomically discordant ventricles and the ventricles connecting with discordant and transposed great arteries. Parallel vessels are evident in corrected @entity13808 , but as this sign is also present in complete @entity13808 , a @entity4297 requiring major cardiac surgery in the postnatal period, it is important to differentiate between the entities prenatally. Most cases of @entity4263 have associated anomalies but isolated forms or those with a mild @entity299 are infrequently detected prenatally. We report on three cases detected between 21 and 25 weeks' gestation on screening ultrasound with associated mild findings. One fetus had an isolated @entity1757 ( @entity1757 ) first detected at 34 weeks. The @entity1 developed @entity616 at 4 years of age. The second case was associated with a small @entity1757 , a tiny pulmonary trunk and a persistent right umbilical vein. After birth, mild @entity849 was found as an additional cardiac finding at 4 months of age. The third fetus had no additional @entity299 prenatally, but after birth a bicuspid aortic valve was detected. The first case needed pacemaker implantation but the other two @entity1 required no cardiac surgery. Two of the cases were referred because abnormal vessel anatomy was detected on screening ultrasound. As prenatal detection of @entity13808 is becoming a more frequent occurrence, this paper aims to present clues aiding in the prenatal diagnosis of @entity713 , especially in its differentiation from complete transposition. These details are crucial for counseling and perinatal management.
