A retrospective study was performed to elucidate the process of left ventricular aneurysm formation and its influence on left ventricular enlargement based on serial two-dimensional echocardiographic observations from 150 consecutive patients with first acute anterior myocardial infarction. Echocardiograms were available and interpretable through the entire period of observation in 68 patients....

The authors report a case of intraoperative reversal apixaban with andexanet alfa in patient supported venoarterial extracorporeal membrane oxygenation due to low- cardiac-output immediately after surgery for acute type A aortic dissection and massive transfusion administration procoagulants. In this patient, alfa's off-label use was not associated thrombotic complications despite being given d...

Conventional unsupervised classification divides all pixels within an image into corresponding classes based on the distance between pixels and the cluster centres. The number of classes must be selected a priori but is seldom ascertainable with little information. To analyze a large dataset, such as a remote sensing dataset, requires an automatic unsupervised classifier which needs no human ef...

Incidence and significance of pericardial effusion in patients with acute myocardial infarction (AMI) have not been established. To evaluate these issues, we studied prospectively 138 consecutive patients with AMI. An echocardiogram was obtained in each 1, 3, and 10 days and 3 and 6 months after admission. Fifty four patients with unstable angina and 57 without heart disease were studied as con...

We used a pulsed Doppler technique to examine the flow velocity pattern in the right ventricular outflow tract in 33 adults. In the patients with normal pulmonary artery pressure (mean pressure < 20 mm Hg, 16 patients), ejection flow reached a peak level at midsystole (137 + 24 msec, mean + SD), producing a domelike contour of the flow velocity pattern during systole. In contrast, the flow velo...

Continuous-wave Doppler echocardiography was used to examine the aortic regurgitant flow velocity pattern in 32 patients with aortic regurgitation (AR) and 10 patients without AR. The aortic regurgitant flow velocity patterns, characterized by a rapid rise in flow velocity immediately after closure of the aortic valve, high peak flow velocity, and a gradual deceleration until the next aortic va...

Objectives. To study whether early postnatal (<12 hours) dexamethasone therapy reduces the incidence of chronic lung disease in preterm infants with respiratory distress syndrome. Materials and Methods. A multicenter randomized, double-blind clinical trial was undertaken on 262 (saline placebo, 130; dexamethasone, 132) preterm infants (<2000 g) who had respiratory distress syndrome and required...
