Left Ventricular Function, Myocardial Perfusion and ViabilityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Cardiac computed tomography is now poised to revolutionize the practice of cardiology. Multi-detector row CT (MDCT) has the potential to evaluate cardiac function, myocardial perfusion, and viability. These capabilities, combined with the robust ability of MDCT to noninvasively image the coronary arteries, makes MDCT a comprehensive tool for the evaluation of coronary artery disease and its anatomic and physiologic impact on the myocardium. Recent technologic advances in MDCT technology in regards to detector coverage, and spatial and temporal resolution promise to improve the capabilities of cardiac CT in the assessment o...

Evaluation of Cardiac Valves Using Multidetector CTEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Cardiac CT is an accurate and reasonable alternative modality for valvular imaging. It is used primarily for the evaluation of coronary artery disease; however, important information regarding valvular anatomy and function can be derived from CT. Calcification is a common CT finding in various valvular abnormalities and carries important diagnostic and prognostic value. In addition, valvular morphology, stenosis, and regurgitation also are detected on contrast enhanced scans, with good correlation with trans-thoracic echocardiography and other techniques.

Cardiac CT in Asymptomatic Patients at RiskEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Atherosclerosis is a systemic process that can develop as early as the second or third decade of life. A significant percentage of patients who experience acute coronary syndromes often have non-obstructive coronary artery disease and thus cannot be diagnosed by their symptoms or conventional functional stress testing. It has been proposed that early detection of atherosclerosis would generate novel opportunities for primary prevention through changes in lifestyle or even through drug therapy, especially in patients at high cardiovascular risk. Calcium scoring is a simple, reproducible, and widely available test that has b...

Diagnostic Accuracy of CT Coronary AngiographyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
There is a rich and rapidly growing literature on the diagnostic utility of coronary CT angiography (CTA) and its performance relative to other modalities such as stress testing and invasive coronary angiography. Earlier studies of 16-slice coronary CTA showed wide variability in sensitivity (30%–95%) and some variability in specificity (86%–98%). With 40- and 64-slice coronary CTA, more of the chest is covered with each spin of the gantry, the breath hold is shorter, and there are fewer uninterpretable segments than with 16-slice coronary CTA. The very high negative predictive value is especially helpful in ruling out...

PrefaceEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Patients with known or suspected coronary artery disease who are asymptomatic or who have stable symptoms are often evaluated noninvasively. Functional tests, such as stress electrocardiography, stress echocardiography, or stress nuclear perfusion imaging, detect and quantify the presence of ischemia based on electrical, mechanical, or perfusion abnormalities, indirectly establishing the burden of coronary artery disease. Although these tests have been shown to provide important prognostic information including the prediction of benefit from revascularization, they have limited accuracy for establishing or excluding the di...

ForewordEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The November 2003 issue of Cardiology Clinics was devoted to cardiac computed tomography (CT). In the intervening 6 years tremendous advances in this technology have occurred. We now can legitimately claim that computed tomography angiography (CTA) of the coronary arteries is available. In the evaluation of patients with suspected coronary artery disease, many guidelines consider CTA an alternative to stress testing. In the typical patient with exercise-induced symptoms, stress imaging still makes sense, but there are many other patients in whom CTA may be preferable. For example, we are using it frequently in pre–noncar...

Enhanced X-Ray Visualization of Coronary Stents: Clinical AspectsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Coronary stent under expansion is a major contributor to in-stent restenosis and acute stent thrombosis. StentBoost and IC Stent are advanced x-ray image enhancing techniques that provide improved stent visualization by eliminating motion artifact. These techniques can be useful in the detection of inadequate stent expansion. These motion-corrected x-ray stent (MXS) visualization techniques are more time-efficient compared to intravascular ultrasound (IVUS), require less training of catheterization laboratory personnel, and have lower procedural costs. However, little clinical or outcome data evidence exist for MXS. Though...

Cardiac neuronal innervation plays an important role in normal cardiac function and is adversely affected in the presence of disease. In particular, radiotracer imaging of cardiac sympathetic function has been extensively investigated and not only provides a method of assessing the severity of disease but also has repeatedly been shown to be prognostically useful with a potential for helping to guide patient management. SPECT imaging of myocardial uptake of 123I-mIBG, an analog of the sympathetic neurotransmitter norepinephrine, has been the most studied, but PET neurotracers, such as 11C-HED, are also under investigation....

Translation of Myocardial Metabolic Imaging Concepts into the ClinicsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Flexibility in myocardial substrate metabolism for energy production is fundamental to cardiac health. This loss in plasticity or flexibility leads to overdependence on the metabolism of an individual category of substrates, with the predominance in fatty acid metabolism characteristic of diabetic heart disease and the accelerated glucose use associated with pressure-overload left ventricular hypertrophy being prime examples. There is a strong demand for accurate noninvasive imaging approaches of myocardial substrate metabolism that can facilitate the crosstalk between the bench and the bedside, leading to improved patient...
