BACKGROUND Little is known about the relation between the extent of microvascular damage and infarct size in patients after successful mechanical reperfusion of acute myocardial infarction. OBJECTIVE To compare the spatial extent of reduced myocardial signal between real time myocardial contrast echocardiography (MCE) and single photon emission computed tomography (SPECT) after successful mec...
BACKGROUND Although defects on intracoronary myocardial contrast echocardiography (MCE) indicate loss of viability after reperfusion, opacified segments may also exhibit persistent dyssynergy. Therefore, we related the intensity and texture of opacification produced by an intravenous contrast agent to histological findings to determine the characteristics of necrotic tissue by postreperfusion M...
INTRODUCTION A rare electrocardiographic finding of hyperkalemia is ST segment elevation or the so called 'pseudoinfarction' pattern. It has been suggested that hyperkalemia causes the 'pseudoinfarction' pattern not only through its direct myocardial effects, but also through other mechanisms, such as anoxia, acidosis, and coronary artery spasm. CASE PRESENTATION A 33-year-old Caucasian woman...
Objective: Primary segmental infarction of the omentum is an infrequent cause of acute abdominal pain in children. We describe our experience with seven children. Methods: A retrospective chart review was performed at a tertiary referral center for 2001. Results: Seven patients, five boys and two girls, presented at the age of 4 to 13 years (average age, 8.7 years). Four patients were above the...
AIMS Separate analysis of endocardial and epicardial myocardial layer deformation has become possible using strain-encoded cardiovascular magnetic resonance (SENC) and 2D-dimensional speckle tracking echocardiography (Echo). This study evaluated and compared both modalities for the assessment of infarct transmurality as defined by late gadolinium enhancement (LGE) cardiovascular magnetic resona...
Abstract Introduction : Acute mesenteric ischemia is a life-threatening condition that can lead to intestinal ischemia, bowel obstruction and peritonitis. It predominantly caused by arterial occlusion (acute thromboembolism or thrombosis); however, it rarely be secondary portal vein thrombosis. Case presentation We present the case of 61-year-old man admitted emergency service for intense abdom...
