Feasibility of SPECT myocardial perfusion imaging in the super-obese using a multi-head semiconductor camera with attenuation correction.

Background: Obesity is not only associated with an increased risk of coronary artery disease, but also decreases the accuracy of many diagnostic modalities pertinent to this disease. Advances in myocardial perfusion imaging (MPI) have mitigated somewhat the effects of obesity, although the feasibility of MPI in the super-obese (defined as a BMI > 50) is currently untested. We undertook this study to assess the practicality of MPI in the super-obese using a multi-headed solid-state gamma camera with attenuation correction.

Right ventricular hemangioma causing right ventricular inflow obstruction and right heart failure.

We report a patient who presented with symptoms of right heart failure. Transesophageal echocardiography revealed a right ventricular mass, causing right ventricular inflow obstruction. Coronary angiography revealed a characteristic tumor blush.

Association of carotid artery intima-media thickness with complex aortic atherosclerosis in patients with recent stroke.

This study was undertaken to determine whether carotid intima-media thickness can predict complex aortic atherosclerosis. A retrospective review was conducted of 64 consecutive patients who underwent transesophageal echocardiography and carotid ultrasonography for evaluation of recent ischemic stroke at MCP Hahnemann University, Medical College of Pennsylvania Hospital between January 1, 1999, and December 31, 1999. The mean age was 65+/-14 years and 59% of the patients were women.
