Purpose Our aim in this study was to investigate the prenatal and postnatal prognosis of double outlet right ventricle (DORV) cases diagnosed prenatally by performing subtype analysis. Methods Patients diagnosed with DORV through prenatal ultrasound in the maternal-fetal medicine department of our hospital between 2014 and 2022 were included in the study group. In this study, the diagnosis of DORV was determined by the ventriculoarterial connection type. Cases of which at least 50% of both great arteries originate from the morphological right ventricle were included. Results Between 2014-2022, 104 fetal DORV cases were diagnosed prenatally. The mean gestational age of the patients at the time of their first visit to our clinic was 23+4 weeks. The cases were categorized according to subtypes which are TGA, fallot, VSD, remote and heterotaxy types. The cases constitute of 32.3% TGA type,19.1% fallot type, 11.1% VSD type, 2% remote type and 35.3% heterotaxy type. Major cardiac anomaly was observed in 87% of DORV cases. Major extracardiac anomaly was observed in 54% of the cases. When we excluded the heterotaxy type without chromosomal anomaly, additional genetic anomalies were detected in 42% of the remaining cases. In 26 cases, pregnancy termination was performed upon the request of the family. Cardiac surgical repair was performed in 48 postnatal cases. The postoperative survival rate was 81.2%. Conclusion The prognosis in DORV depends on the anatomical subtype, the presence and severity of associated additional anomalies. In this disease, which has a high incidence of additional cardiac and extracardiac anomalies, the survival rate is high when these anomalies are absent and genetic problems are not observed. While informing the family about fetal prognosis, the long treatment and follow-up period waiting for them should be emphasized.
