Abstract

Previous approaches to automatic border recognition in two-dimensional echocardiography have utilized off-line computer image analysis. In this paper, we describe a hardware technique for real-time endocardial edge detection during the echocardiographic examination. This technique is based on a new method of line-by-line compensation for ultrasound attenuation. The detected edges and composite edge images can be displayed alone or superimposed upon the usual echocardiographic display. To test the accuracy of our real-time technique, we obtained echocardiograms of excised hearts and compared real-time edges with edges manually traced by an experienced observer. Left ventricular cavity areas and endocardial perimeters derived from real-time edges correlated well with those derived from observer-defined edges.

Electrocardiographic prediction of left ventricular geometric patterns in patients with essential hypertension.

BACKGROUND: The present study sought to determine the diagnostic value of electrocardiographic voltage criteria in predicting geometry patterns in patients with essential hypertension. METHODS: Patients with essential hypertension (n=125) according to left ventricular mass index and relative wall thickness as determined by echocardiography were assigned in the following groups: normal geometry (N, n=50), concentric remodeling (CR, n=12), concentric hypertrophy (CH, n=28) and eccentric hypertrophy (EH, n=35). Each patient underwent 12-lead ECG followed by determination of conventional voltage criteria as well as peak to peak QRS lengths in each lead. RESULTS: Voltage criteria such as Sokolow-Lyon, Cornell, Cornell product >2440, D1R+D3S >25 mm, and AVL R >11 mm could not significantly predict and discriminate geometric patterns of LVH. However, they all were very specific (range 97-100%) and showed very high positive predictive values (range 94-100%) for detecting abnormal geometry. DI peak >12 mm had a sensitivity 61%, specificity 67%, accuracy 63%, positive predictive value 81%, and negative predictive value 42% in predicting to differentiate CH from CR. Sum of the calculated values from the peak of the R to the nadir of the S wave in all limb leads >60 mm had sensitivity 68%, specificity 75%, accuracy 70%, positive predictive value 86% and negative predictive value 50% in predicting to differentiate CH from CR. CONCLUSIONS: Conventional ECG voltage criteria could not significantly discriminate specific geometry patterns observed in patients with essential hypertension.

Echocardiographic evidence of posteromedial hypokinesis of the left ventricle in relation to mitral regurgitation in cardiac sarcoidosis.

We describe herein the case of a 49-year-old female patient with pulmonary sarcoidosis (stage II) with cardiac manifestation. This consisted of systolic dysfunction without dilatation of the left ventricle and severe mitral insufficiency, possibly due to thinning of the posteromedial left ventricular free wall, based on our echocardiographic observations.
