Benign lipomatous lesions of the heart encompass an apparently etiologically diverse group of entities including neoplastic, congenital, and reparative phenomena. Among these, lipomas and lipomatous hypertrophy of the atrial septum (LHAS) represent 2 commonly encountered mass lesions. To date, no study has systematically and comparatively evaluated the(More)
Foreign objects are occasionally seen on computed tomography and could pose a diagnostic challenge to the radiologist and clinicians. It is important to recognize, characterize and localize these objects and determine their clinical significance. Most foreign objects in and around the heart are the result of direct penetrating injury or represent venous(More)
We report a rare case of ergotamine-associated mitral stenosis in a 55-year-old woman who presented with recurrent chylous pleural effusion. Echocardiographic, gross, and microscopic features of the mitral valve were consistent with chronic ergotamine-induced valvulopathy. We conclude that medication-induced valvulopathy should be included in the(More)
OBJECTIVE The diagnostic yield of combined cardiopulmonary exercise testing (CPET) and myocardial perfusion imaging (MPI) in patients referred for stress testing has received limited study. METHODS We evaluated consecutive patients who underwent combined CPET-MPI at a single tertiary referral center between 2011 and 2015. An abnormal CPET was defined as(More)
We report the spectrum of aortic involvement in patients with giant cell arteritis (GCA) following review of medical records of 4,006 patients including those with imaging studies. A total of 1,450 patients (36%) had a confirmed diagnosis of GCA. Of these, 974 had aortic imaging. Of the 974 patients with imaging, 435 (45%) had an identified aortopathy. The(More)
BACKGROUND Atrial fibrillation (AF) is the most common sustained atrial arrhythmia. One potential target for ablation is left atrial (LA) scar (LAS) regions that may be the substrate for re-entry within the atria, thereby sustaining AF. Identification of LAS through LA delayed gadolinium enhancement (LADE) with MRI has been proposed. OBJECTIVES We sought(More)
