An unusual case of prenatal diagnosis of right coronary artery to right ventricle fistula with HD-flow render mode and spatiotemporal image correlation (STIC).

Coronary artery fistula is rare in prenatal diagnosis. We have reported a case diagnosis of coronary artery fistula by using high-definition flow (HD-flow) render mode and spatiotemporal image correlation (STIC), and then evaluated the postnatal outcomes in our hospital.
