In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.
Objective To explore the dominant views with positive results when performing echocardiography on common congenital heart disease (CHD) in children using the seven-step screening method for pediatric echocardiography. MethodsThe echocardiographic data of children with atrial septal defect, patent foramen ovale, ventricular septal defect, and patent ductus arteriosus were collected from September 2021 to February 2022. The disease type distribution, view distribution, and the dominant view distribution were analyzed. Dominant view referred to the view with a high ratio of positive result images per view to the total image in each disease. Results A total of 8 353 images of 1 633 children with common CHD were collected. There were 813 males and 820 females ageed 0-7 years, including 3 613 images in 701 patients with atrial septal defect, 1 178 images in 206 patients with patent foramen ovale, 2 857 images in 576 patients with ventricular septal defect, and 705 images in 150 patients with patent ductus arteriosus. The dominant views of atrial septal defect were subxiphoid 2-chamber view (92.96%), subxiphoid 4-chamber view (85.61%), parasternal 4-chamber view (62.07%), and parasternal short-axis view (38.50%). The dominant views of patent foramen ovale were subxiphoid 2-chamber view (82.69%) and subxiphoid 4-chamber view (65.41%). The dominant views of ventricular septal defect were parasternal 5-chamber view (79.73%), parasternal short-axis view (79.41%), parasternal 4-chamber view (58.18%), and parasternal long-axis view (51.11%). The dominant view of patent ductus arteriosus was parasternal short-axis view (98.80%). Conclusion The analysis of the lesion key areas of common CHD shows that there are 4 dominant views for atrial septal defect and ventricular septal defect, 2 for patent foramen ovale, and only 1 for patent ductus arteriosus. Clarifying the dominant views of common CHD is conducive to rapid and accurate diagnosis of diseases, clinical practice, teaching and scientific research.
