Key result
Prenatal ultrasound guides successful early surgical repair of a fetal coronary artery fistula.
Why the study?
Congenital coronary artery fistula is a rare malformation for which prenatal diagnosis remains challenging.

Prenatal ultrasound enables early diagnosis of congenital coronary artery fistula, guiding timely postnatal surgical intervention and improving outcomes.
May support targeted prenatal detection in rare fistulas; hypothesis-generating and requires prospective studies before changing screening practice.
Congenital coronary artery fistula (CAF) is a rare congenital cardiovascular malformation characterized by an anomalous connection between a coronary artery and a cardiac chamber or great vessel. Prenatal diagnosis remains challenging. A 29-year-old G2P1 pregnant woman was diagnosed with fetal left coronary artery-to-right ventricle fistula via prenatal ultrasound at 21 weeks. Postpartum follow-up showed progressive coronary dilation, leading to surgical repair. A cardiac enhanced CT scan also confirmed the diagnosis of CAF. One-year postoperative ultrasound revealed improved cardiac structure with residual mild complications. Prenatal ultrasound is pivotal for early CAF diagnosis, guiding postnatal intervention and improving prognosis.

Huang et al. (2026) conducted a case report in Congenital coronary artery fistula (n=1). Prenatal ultrasound diagnosis and surgical repair was evaluated on Clinical and echocardiographic outcomes post-surgery. Prenatal ultrasound successfully diagnosed a fetal left coronary artery-to-right ventricle fistula, enabling timely postnatal surgical repair that resulted in improved cardiac structure with only mild residual complications at one year.
