Twelve patients with dextro-transposition of the great vessels (age eight months to four years) were studied by echocardiography following Mustard's procedure. Nine of them had also been studied preoperatively. Postoperatively all patients demonstrated structural echoes in the atrial cavity behind the pulmonary root. In ten, the motion pattern generally resembled that of a stenotic atrioventric...

This excellent monograph by Phillippe Sengel brings together an enormous body of data on the embryonic development of the skin in mammals, birds, and reptiles, and most of the information available on the many chemical factors and tissue interactions which produce these changes. The book is divided into four sections. The first describes the histogenesis of developing skin visible with the ligh...

background: the late postoperative course for children with transposition of the great arteries (tga) with an intact ventricular septum (ivs) is very important because the coronary arteries may be at risk of damage during  arterial switch operation (aso). we sought to investigate left ventricular function in patients with tga/ivs by echocardiography. methods: from march 2011 to december 2012, t...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

x-ray coronary angiography has been a gold standard in the clinical diagnosis and interventional treatment of coronary arterialdiseases for decades. in angiography, a sequence of images is obtained, a few of which are suitable for physician inspection. thispaper proposes an automatic algorithm for the extraction of one or more frames from an angiogram sequence, which is most suitablefor diagnos...

objective(s) diabetes related dysfunction of resistance vessels is associated with vascular occlusive diseases. vasorelaxant agents may have a role in control of diabetic cardiovascular complications. gamma aminobutyric acid (gaba) has demonstrated to cause vasorelaxation. the present study was designed to determine i) the vasorelaxatory effect of gaba on diabetic vessels and ii) the role of en...

detecting blood vessels is an important task in retinal image analysis.  the task is more challenging with the presence of bright and dark lesions in retinal images. here, a method is proposed to detect vessels in both normal and abnormal retinal fundus images based on their linear features. first, the negative impact of bright lesions is reduced by using k-means segmentation in a perceptive sp...
