This review provides an overview of prenatal interventional treatments for fetal congenital heart disease (CHD), with a particular focus on the latest advancements in fetal aortic valvuloplasty (FAV) and fetal pulmonary valvuloplasty (FPV). FAV aims to improve left heart hemodynamics, prevent hypoplastic left heart syndrome (HLHS), and promote biventricular circulation. FPV seeks to improve the natural history of pulmonary atresia with intact ventricular septum (PA/IVS) and critical pulmonary stenosis with intact ventricular septum (CPS/IVS), alleviate right ventricular outflow tract obstruction, and promote biventricular circulation. This article discusses patient selection, technical details, risk assessment, and clinical outcomes for these procedures, highlighting the challenges in current research, including the lack of standardized patient selection criteria and long-term prognostic studies. Additionally, it emphasizes the opportunities and challenges of fetal cardiac intervention (FCI) development in China and proposes recommendations for future improvements and research directions.

Objective To investigate visual impairment students' quality of life and its influencing factors in Braille learning class at Quanzhou Special School. Methods November, 2020, 52 students (aged seven to 26) with the best corrected distance visual acuity of the better eye above 0.02 were investigated with near visual acuity, contrast sensitivity and Chinese-version Low Vision Quality of Life Questionnaire (CLVQOL). The subjects were divided into second grade blindness group, first grade low vision group and second grade low vision group according to the best corrected distance visual acuity of the better eye. Results There were significant differences in distance visual acuity (Z = 45.671, P < 0.001), near visual acuity (Z = 24.972, P < 0.001), and contrast sensitivity (CS) ( Z = 13.285, P = 0.001) among three groups. There was a correlation between near visual acuity and distance visual acuity (r = 0.74, P < 0.001), CS to distance visual acuity (r = -0.58, P < 0.001) and near visual acuity (r = -0.57, P < 0.001), score of CLVQOL and CS (r = 0.44, P < 0.001). There were significant differences in the total score (Z = 10.145, P = 0.006), distance visual acuity subscale (Z = 13.586, P = 0.001), psychological adjustment subscale (Z = 7.824, P = 0.020), reading and fine work subscale (Z = 7.923, P = 0.019) of CLVQOL among the three groups. Conclusion Quality of life is different with the visual impairment for students in special school, especially the distance visual acuity, psychological adjustment and fine reading. CS correlates to the quality of life of visually impaired students, which needs to be a part of evaluation of visual function.
