许多青紫型先天性心脏病的心功能呈异常,包括肺动脉瓣闭锁、大动脉错位、法乐氏四联症及三尖瓣闭锁等,其中有些畸形即使经手术纠正,心功能仍不正常。心功能异常是与青紫程度抑或与青紫持续时间的长短有关,仍不了解。本文报道在姑息性手术前后用双平面电影心血管造影估计左室功能,探讨左室功能异常与青紫程度、持续时间以及左室大小的关系。方法:62例青紫型先天性心脏病患者,包括18例三尖瓣闭锁、26例肺动脉瓣闭锁或危重肺动脉瓣
Many cyanotic congenital heart disease abnormal heart function, including pulmonary atresia, dislocation of the arteries, tetralogy of Fallot and tricuspid atresia, some of them even if the surgery corrected, cardiac function is still not normal. Abnormal cardiac function is related to the degree of cyanosis or the duration of cyanosis, and is still not understood. This article reports the use of dual-plane cine cardiovascular angiography to assess left ventricular function before and after palliative surgery to investigate the relationship between left ventricular dysfunction and cyanosis degree, duration, and left ventricular size. Methods: Sixty-two patients with cyanosis congenital heart disease, including 18 cases of tricuspid atresia, 26 cases of pulmonary valve atresia or critical pulmonary valve
