The study named " The role of myocardial perfusion gated SPECT study in women with coronary artery disease " reveals some current and important issues in diagnosing myocardial ischemia in women (1). Because the obesity is the highest and the death from coronary artery disease (CAD) is the second highest in Turkish women among all European countries, diagnosing CAD in women becomes much more imp...

Ultrasound and MRI are useful in assessing wall motion and systolic thickening with 2D images. Volumetric data of the helical CT provide frozen 3D images. We sought to determine whether helical CT could assess left ventricular wall motion with 3D animation. We have developed a new cardiac application, ventriculography by 4D enhanced helical CT (4D-CT-VG), which can assess wall motion with 3D an...

BACKGROUND Wall motion score at dobutamine stress echocardiography is an independent predictor of mortality. We sought to determine whether quantification of DSE by strain rate imaging was incremental to wall motion score for predicting outcome. METHODS AND RESULTS In 646 patients undergoing dobutamine stress echocardiography for the evaluation of known or suspected coronary disease, customiz...

Introduction: The aim of this study was to estimate myocardial motion directly from a conventional SSFP (steady-state free precession) cine-MRI sequence. This sequence provides precise morphological information coupled with an adequate temporal resolution and excellent contrast between structures. We propose to use information naturally present in SSFP Cine-MRI for myocardial motion estimation....

Previous 2DE studies have suggested that left ventricular wall thickening determinants of regional left ventricular function may be more precise than left ventricular wall motion parameters in the assessment of myocardial ischemia and infarction. To study the relationship between regional wall motion and regional wall thickening abnormalities relative to myocardial ischemia, we performed 2DE in...

Background Feature tracking (FT) software packages measure myocardial wall motion deformation parameters through the cardiac cycle. Myocardial tagging technique is currently considered the gold standard for myocardial deformation measurements. This study compares 2 FT-software packages with a tagging software package and investigates the differences in strain deformation parameters measured in ...

A 39 year old man with postoperative constrictive pericarditis after pericardiectomy developed major left ventricular systolic dysfunction with an anterior wall infarct pattern on ECG but no regional wall motion abnormalities by echocardiography or serum enzymatic evidence of a myocardial infarction. The left ventricular dysfunction resolved over two weeks with supportive treatment. It is postu...

OBJECTIVES (15)O-water-perfusable tissue fraction (PTF) has been shown to be a potential index for assessing myocardial viability in PET, an alternative to (18)F-fluorodeoxyglucose (FDG). This study aimed to directly compare these two independent methods in assessing myocardial viability in patients with abnormal wall motion. METHODS PET study was performed on 16 patients with previous myocar...

OBJECTIVES This study sought to determine the prognostic value of wall motion and perfusion assessment during high-dose dobutamine stress (DS) cardiac magnetic resonance imaging (MRI) in a large patient cohort. BACKGROUND DS-MRI offers the possibility to integrate myocardial perfusion and wall motion analysis in a single examination for the detection of coronary artery disease (CAD). METHOD...

UNLABELLED A 52-year-old man presented after one episode of effort angina, normal treadmill electrocardiogram (ECG), and clearly positive adenosine cardiac magnetic resonance (aCMR) for reversible perfusion defects in the left anterior descending (LAD) coronary artery territory. Contrast high-dose dipyridamole (0.84 mg/kg per 6 min) stress echocardiography (cSE) demonstrated normal myocardial p...
