Previous studies on the association of ankylosing spondylitis and abnormalities of the lung parenchyma have been based largely on plain radiography and pulmonary function testing. This study, although uncontrolled, is the first to use high-resolution computed tomography to examine the entire lung parenchyma in ankylosing spondylitis patients, and to(More)
Late-onset sporadic Alzheimer's disease is a heterogeneous disorder. In elderly patients, increasing evidence suggests a link between this neurodegenerative disease, and vascular risk factors and atherosclerosis. The nature of this link remains speculative. Some investigators have suggested that the disease arises as a secondary event related to(More)
Aortocoronary dissection complicating diagnostic angiography or percutaneous coronary intervention is a rare occurrence. We present a case of aortocoronary dissection complicating a right coronary artery intervention. After closing the entry port with intracoronary stenting, the patient was managed conservatively. Serial computed tomography scans(More)
OBJECTIVES The purpose of this research was to define the predictors of the "slow-reflow" phenomenon during carotid artery intervention with filter-type embolic protection devices (EPDs) and to determine its prognostic significance. BACKGROUND During carotid artery intervention using filter-type EPDs, we have observed cases in which there is angiographic(More)
OBJECTIVE The aims of this study were to identify the spectrum of abnormalities seen on high-resolution CT in patients with ankylosing spondylitis and to compare our findings with reports of plain film pulmonary manifestations of the disease. SUBJECTS AND METHODS We prospectively studied 26 patients with documented ankylosing spondylitis. All patients(More)
A potential complication of mitral valve replacement surgery is the development of a paravalvular leak (PVL). Percutaneous transcatheter closures of PVLs using a wide array of devices have been reported in the literature, although the procedural success rate of this approach remains variable. One major challenge of transcatheter mitral PVL closure lies in(More)
BACKGROUND Although most randomized clinical trials have suggested that long-term survival rates after percutaneous coronary intervention (PCI) or surgical multivessel coronary revascularization (CABG) are equivalent, some post hoc analyses in high-risk groups and adjustment for severity of coronary disease have suggested higher mortality after PCI.

OBJECTIVE To evaluate the clinical utility of images acquired from rotational coronary angiographic (RA) acquisitions compared to standard "fixed" coronary angiography (SA). BACKGROUND RA is a novel angiographic modality that has been enabled by new gantry systems that allow calibrated automatic angiographic rotations and has been shown to reduce(More)
OBJECTIVE To determine the safety and efficacy of dual-axis rotational coronary angiography (DARCA) by directly comparing it to standard coronary angiography (SA). BACKGROUND Standard coronary angiography (SA) requires numerous fixed static images of the coronary tree and has multiple well-documented limitations. Dual-axis rotational coronary angiography(More)
