OBJECTIVE The purpose of our study was to evaluate the accuracy of cardiac 64-MDCT to quantify the grade of stenosis of nonculprit lesions. SUBJECTS AND METHODS Twenty-nine consecutive patients (23 men and six women; mean age, 62 +/- 10 years) presenting with acute coronary syndrome (ACS) had nonculprit coronary lesions of >or= 30% stenosis quantified on(More)
OBJECTIVE This article reviews the optimal cardiac MRI sequences for and the spectrum of imaging appearances of cardiac tumors. CONCLUSION Recent technologic advances in cardiac MRI have resulted in the rapid acquisition of images of the heart with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MRI provides(More)
Recent technologic advances in cardiac magnetic resonance (MR) imaging have resulted in images with high spatial and temporal resolution and excellent myocardial tissue characterization. Cardiac MR is a valuable imaging technique for detection and assessment of the morphology and functional characteristics of the nonischemic cardiomyopathy. It has gained(More)
BACKGROUND Recent advances in 64-slice multidetector computed tomography (MDCT) provide an opportunity to assess coronary artery disease, left ventricular function and, potentially, valvular heart disease. OBJECTIVE To determine the ability of 64-MDCT to both detect and to quantify the severity of aortic regurgitation (AR), as compared with transthoracic(More)
BACKGROUND The objective was to compare the value of late gadolinium enhancement (LGE) and end-diastolic wall thickness (EDWT) assessed by cardiovascular magnetic resonance (CMR) in predicting recovery of left ventricular function after coronary artery bypass surgery (CABG). METHODS We enrolled patients with coronary artery disease and left ventricular(More)
To determine the prognosis of a myocardial scar assessed by a late gadolinium enhancement (LGE) technique of cardiac magnetic resonance (CMR) in hypertensive patients with known or suspected coronary artery disease (CAD). Patients with systemic hypertension with known or suspected CAD without a clinical history of myocardial infarction were enrolled. All(More)
The accuracy of various electrocardiographic (ECG) criteria for the diagnosis of healed myocardial infarction (MI) has never been validated. The objective of this study was to determine the accuracy and prognostic value of standard ECG criteria for the diagnosis of healed MI compared with cardiac magnetic resonance (CMR). Consecutive patients with known or(More)
Previous studies focused on attaining low-density lipoprotein cholesterol (LDL-C) goals after lipid-modifying therapy (LMT), but data on achieving normal levels of triglyceride and high-density lipoprotein cholesterol (HDL-C) are limited. We reviewed medical records of patients initiated on LMT. High risk was defined as patients with coronary heart disease,(More)
Late gadolinium enhancement (LGE) and myocardial perfusion study by cardiac magnetic resonance (CMR) have a diagnostic and prognostic value in patients with suspected coronary artery disease (CAD). The purpose of this study was to determine the prognostic value of combined myocardial perfusion CMR and LGE in patients with known or suspected CAD. We studied(More)
BACKGROUND Transthoracic echocardiographic examinations in women with large breasts are technically demanding and can lead to suboptimal image quality, excessive scan time, and cause pain and discomfort to patients. OBJECTIVE Evaluate the effects of self-made breast sling used during transthoracic echocardiographic examination on scanning time, image(More)
