OBJECTIVE
To study regional wall motion of the systemic ventricle in patients after the Fontan operation.
DESIGN AND PATIENTS
Systemic ventricular angiograms of 15 patients after the Fontan operation and of 11 unoperated patients with a univentricular atrioventricular connection were digitised frame by frame. Strict criteria for abnormal wall motion were used so that minor abnormalities were not considered.
RESULTS
Incoordinate contraction of the ventricular wall was found in five of the 11 patients before and in four of the 15 patients after the Fontan operation (NS). Only three of the 11 patients before the Fontan operation, showed incoordination of ventricular relaxation, but incoordinate relaxation was seen in 12 of the 15 patients after operation (p less than 0.01).
CONCLUSIONS
Whereas incoordination of ventricular contraction was common in patients with a univentricular atrioventricular connection, before or after the Fontan operation, incoordinate relaxation of the ventricular wall was a common consequence of the Fontan operation and was rare in patients before operation.
目的
研究Fontan手术患者体循环心室的局部室壁运动。
设计与患者
对15例Fontan手术后患者和11例未手术的单心室房室连接患者的体循环心室血管造影进行逐帧数字化处理。采用严格的室壁运动异常标准，不考虑轻微异常情况。
结果
在Fontan手术前的11例患者中有5例发现室壁不协调收缩，Fontan手术后的15例患者中有4例出现这种情况（无显著性差异）。Fontan手术前的11例患者中只有3例表现出心室舒张不协调，但手术后的15例患者中有12例出现舒张不协调（p<0.01）。
结论
单心室房室连接患者无论在Fontan手术前还是术后，心室收缩不协调都很常见，而心室壁舒张不协调是Fontan手术的常见后果，在手术前患者中很少见。
