Abstract:

Fetal cardiac intervention (FCI) has evolved since its inception in 1991. With the improvement in technical success rates, reduction in complications, and enhancement of fetal outcomes, this technique has gradually gained recognition and promotion. The establishment of the International Fetal Cardiac Intervention Registry has facilitated international exchange and technological development in this field, with over 400 clinical cases reported worldwide. In China, several medical institutions in Guangdong, Shanghai, Qingdao, Chongqing, and other regions have initiated in-utero cardiac intervention treatments, although the number of cases remains limited. This article summarized the types of fetal in-utero cardiac interventions, the procedural process, surgical complications, indications for treatment, and treatment outcomes, while also highlighting current challenges and future prospects of the technology.
