BACKGROUND We assessed geometric changes responsible for acute lumen loss at the left circumflex coronary artery (LCX) ostium after crossover stenting from the left anterior descending coronary artery (LAD) to the left main artery. METHODS AND RESULTS Twenty-three left main artery bifurcation lesions with a preprocedural angiographic diameter stenosis <50% at the LCX ostium were evaluated usi...

Background. It is well known that the pulmonary veins (PVs), especially their myocardial sleeves play a critical role in the initiation and maintenance of atrial fibrillation. Understanding the PV anatomy is crucial for the safety and efficacy of all procedures performed on PVs. The aim of this study was to present normal distal PV anatomy and to create a juxtaposition of all PV ostium variants...

THE 4 forms of interatrial comnmunication -ostium secundum, ostium primum, common atrium, and total anomalous pulmonary venous connection-are associated with clinical symptoms and signs and radiologic, electrocardiographic, anid physiologic features that permit proper differential diagnosis in most instanees. The usual type of atrial septal defect, ostium secundum, is by far the most common for...

OBJECTIVE To clarify the three-dimensional anatomical features of the sphenoid sinus and its surrounding structures as are relevant to performing an endoscopic sphenoidotomy. METHODS Various dimensions of 224 CT images of the sphenoid sinus and surrounding structures from 122 Japanese adult patients were measured using the multiplanar reconstruction technique. RESULTS The mean distance from...

A case of eccrine carcinoma of the interdigital foot glands in a 39-yr-old female Asian elephant (Elephas maximus) from Zagreb Zoo is described. The tumor between the toenails of the right forefoot was surgically removed 3 yr before postmortem examination (2003), and the histopathologic diagnosis was compound eccrine carcinoma characterized with glandular tubular and papillary proliferations, m...

Eccrine syringofibroadenoma (ESFA) is a rare tumor originated from eccrine ductal portion [1,2]. Clinically, ESFA presents a solitary papule, nodule or plaque to multiple lesions. Cases with multiple papular or macular lesions have been often associated with hereditary ectodermal dysplasia [3]. Recent findings have classified ESFA into several groups including, solitary ESFA, multiple ESFA with...
