27 patients with following diagnoses were examined by ultrasound: ASD; Aortic valve disease; Mitral valve disease with predominant insufficiency; Mitral stenosis; right heart failure; patients without evidence of cardiac disease. The right ventricular dimension (RVD Index) was assessed representing the distance between the right ventricular epicardial echoes and echoes from the right side of the interventricular septum divided by the patient's body surface area, analogue measurements were done to obtain the left ventricular dimension (LVD Index). The ratio from LVD to RVD was calculated. The motion of the interventricular septum was classified as Normal, Abnormal A and Abnormal B, according to known criteria. Three groups of patients could be differentiated: Patients without cardiac disease; Patients with right ventricular enlargement and ASD; Patients with left ventricular enlargement with aortic and mitral valve disease. In patients with cardiac enlargement, echocardiography provides better information concerning the ratio of the left ventricular to the right ventricular diameter compared to a routine chest X ray.
对27例患有以下疾病的患者进行了超声检查：房间隔缺损；主动脉瓣疾病；以二尖瓣关闭不全为主的二尖瓣疾病；二尖瓣狭窄；右心衰竭；无心脏病证据的患者。评估右心室尺寸（右心室直径指数），即右心室心外膜回声与室间隔右侧回声之间的距离除以患者体表面积，进行类似测量以获得左心室尺寸（左心室直径指数）。计算左心室直径与右心室直径的比值。根据已知标准，将室间隔运动分为正常、异常A和异常B。可区分出三组患者：无心脏病患者；右心室扩大合并房间隔缺损患者；左心室扩大合并主动脉瓣和二尖瓣疾病患者。与常规胸部X线相比，超声心动图在心脏扩大患者中能提供有关左心室与右心室直径比值的更好信息。
