Left ventricular performance and compliance following acute febrile mucocutaneous lymphnode syndrome

Right and left heart catheterizations and biplane cineangiographies were performed on 115 post-MCLS cases to study the left ventricular performance and compliance, and the following conclusions were obtained: 1) The left ventricular performance of the post-MCLS cases with macroscopic cardiac lesions such as coronary aneurysms and stenosis declined compared with the others. 2) The left ventricular contractility of the post-MCLS cases without macroscopic cardiac lesions were within normal limits. 3) The diastolic compliance of the post-MCLS cases seemed to be decreased but the value could be regarded as normal for children.
