Background: proper assessment of patients with ischemic cardiomyopathy is a key determinant for management other investigations, improving the patient’s quality life and reducing future cardiac events. This study was conducted to evaluate value myocardial MIBI washout rate using delayed resting perfusion imaging in limited resources countries. Patients Methods: this prospective included 86 (64 ...

A 43-year-old man with type 2 diabetes mellitus was referred for cardiovascular risk assessment 2 years ago. Other risk factors for coronary artery disease included hypercholesterolemia, smoking, and a family history of coronary artery disease. The patient was asymptomatic. Physical examination was unremarkable; his body mass index was 22 kg/m and his blood pressure was 125/80 mm Hg. Hyperchole...

Left ventricular (LV) systolic timing and relative volume variations were simultaneously measured by electromagnetic flowmeter (EMF) and high frame rate ECG-gated blood pool scintigraphy in five baboons. No significant differences (p greater than 0.1, paired t test) were observed in the time (from R wave) to peak aortic flow (maximum LV ejection rate), time to cessation of aortic flow (end-syst...

We recovered a novel mouse mutant exhibiting neonatal lethality associated with severe fetal cardiac hypertrophy, and with some adult mice dying suddenly with left ventricular hypertrophic cardiomyopathy. Using Doppler echocardiography, we screened surviving adult mice in this mutant line for cardiac hypertrophy. Cardiac dimensions were obtained either from 2D images collected using a novel ECG...

Sensitivity and specificity of the modified Duke criteria for native valve endocarditis are both suboptimal, at approximately 80%. Diagnostic accuracy for intracardiac prosthetic material-related infection is even lower. Non-invasive imaging modalities could potentially improve diagnosis of infective endocarditis; however, their diagnostic value is unclear. We did a systematic literature review...

BACKGROUND The mid-term prognostic significance of ECG-gated single-photon emission computed tomography (SPECT) remains unclear in Japanese patients with type 2 diabetes mellitus (DM). In the present study rates of future cardiac events (nonfatal acute myocardial infarction (AMI), cardiac death (CD) and severe heart failure (HF) requiring hospitalization) were compared in patients with and with...

The aim of the study was to assess the feasibility of CT based 3D analysis of degenerated aortic bioprostheses to make easier their morphological assessment. This could be helpful during regular follow-up and for case selection, improved planning and mapping of valve-in-valve procedure. The challenge was represented by leaflets enhancement because of highly noised CT images. Contrast-enhanced E...

BACKGROUND AND PURPOSE Brain pulsation is a well-known observation in neurosurgery, but methods for its visualization on MR imaging, like phase imaging, do not provide a detailed structural view. We prospectively investigated electrocardiographic (ECG)-gated cine true fast imaging with steady-state precession (FISP) sequence on volunteers to test a sequence for demonstrating brain pulsation and...
