临床协议说明

For this algorithm, "Time 0" is the initial evaluation by an experienced pediatric cardiologist. There was considerable debate among committee members as to whether echocardiographic definition of a small ventricular septal defect was necessary to exclude other conditions that could mimic the physical findings of a small ventricular septal defect or associated problems such as prolapse of an aortic valve cusp. After considerable discussion, it was decided to construct the algorithm for patients with a small ventricular septal defect in whom an echocardiogram had been done. However, the committee recognized that some pediatric cardiologists diagnose a small ventricular septal defect without echocardiographic confirmation of the defect or echocardiographic exclusion of associated problems. The committee agreed that diagnosis and management of patients with a small ventricular septal defect without echocardiographic confirmation was acceptable. Under these circumstances, it is incumbent on the clinician to provide appropriate ongoing evaluation to detect and manage conditions that could mimic the physical findings of a small ventricular septal defect or the problems associated with it.
