BACKGROUND Coronary artery enlargement has been previously described in left ventricular hypertrophy. OBJECTIVES We sought to assess coronary artery dimensions and their relation to left ventricular muscle mass in primary and secondary hypertrophy. METHODS Cross-sectional area of the left and right coronary arteries was determined by quantitative coronary angiography in 52 patients: 12 cont...

INTRODUCTION AND OBJECTIVES Provisional stenting has been shown to be effective in the treatment of bifurcated coronary lesions. The aim of this study was to evaluate changes in the geometry of the main vessel stent following side branch (SB) dilatation and kissing balloon (KB) inflation. METHODS The study involved 23 patients with a bifurcated coronary lesion. A first intravascular ultrasoun...

The purpose of the present study was to determine the relationship between cross-sectional design and fracture load using a static load bearing test in yttria-stabilized tetragonal zirconia polycrystal ceramic frameworks on a molar fixed partial denture. The test framework was designed as a 3-unit bridge with two abutment teeth at the second premolar and second molar of the mandible. The cross-...

OBJECTIVE Compare levator ani cross-sectional area as a function of prolapse and muscle defect status. METHODS Thirty women with prolapse and 30 women with normal pelvic support were selected from an ongoing case-control study of prolapse. For each of the two groups, 10 women were selected from three categories of levator defect severity: none, minor, and major identified on supine magnetic r...

Assessment of nasal airway is helpful in understanding nasal breathing function. Acoustic rhinometry is one of the most commonly-used objective measurements of nasal airway. This test has the ability to measure the volume and the cross-sectional area of the nose in different distances. It also determines the site of minimal cross-sectional area. These variables are different in various races. D...

Objectives To assess the relationship between cross-sectional area of internal jugular veins and brain volumes in healthy individuals without neurologic disease. Methods A total of 193 healthy individuals without neurologic disease (63 male and 130 female; age > 20 to < 70 years) received magnetic resonance venography and structural brain magnetic resonance imaging at 3T. The internal jugular v...
