功能性单心室是一组复杂的发绀型先天性心脏病,其心功能评估和治疗一直备受关注.近年来,在心功能评估方面,应用组织多普勒反映心室的收缩和舒张功能;通过速度向量成像技术反映局部心肌组织真实的运动方向和大小;通过磁共振技术更为准确地计算出功能性单心室的各项心功能指标.在治疗方面,镶嵌治疗是一种新的手术模式,另外对于行房坦手术后心力衰竭的功能性单心室患者,最近研制的人造右心室的轴流泵提供一种新的治疗方向.%Functional single ventricle is a group of complex cyanotic congenital heart disease. The assessment of ventricular function and therapy of single ventricle have caused great concern, and some new advances are seen in recent years. Tissue Doppler imaging at multiple points of functional single ventricle provides a complete,accurate assessment of systolic and diastolic function; velocity vector imaging provides the real motion direction and size of the local myocardial in functional single ventricle;magnetic resonance imaging provides a more accurate assessment of ventricular function of functional single ventricle. Hybrid procedure is a new technique in the surgery treatment. An artificial right ventricle axial pump provides a new therapy for patients suffering heart failure from functional single ventricle after Fontan surgery.
