Echocardiographic studies of the mitral valve were performed in 57 patients with pure or predominant mitral stenosis who subsequently underwent surgery (30 commissurotomy, 27 valve replacement). Mitral valve calcification was graded heavy (thick, conglomerate echoes), light (multiple, discrete linear echoes) or none (thin, single or duplicate signals). Valve mobility, measured as the excursion ...

basal encephalocele is a rare craniofacial anomaly. in the present paper we report a 10-year-old boy presented with cleft palate, congenital nystagmus, and hypertelorism. during preoperative evaluation for cleft palate repair, a pulsatile mass was detected in the pharynx. magnetic resonance imaging showed sphenoethmoidal type of basal encephalocele and agenesis of corpus callosum. neurosurgical...

The current standards for preoperative cardiac evaluation and the guidelines published by the American College of Cardiology and the American Heart Association call for noninvasive or invasive cardiac evaluation in certain patients. Perioperative use of beta-adrenergic blockade has been shown to reduce cardiac complication rates, diminishing the positive predictive value and the likelihood rati...
