The cardiac imaging field has experienced significant improvements over the last decade due to technological advances. Cardiac computed tomography (CT), cardiac magnetic resonance imaging (MRI), nuclear cardiology, and echocardiography have all become feasible imaging modalities for physicians to evaluate in order to answer specific diagnostic questions. Each of the aforementioned modalities has…

Since the 1980s, dramatic advances in electrophysiology procedures have occurred. Catheter positioning is most often assisted by fluoroscopy. Sophisticated electroanatomical mapping systems can also display catheter position and create a 3D depiction of the anatomy. Magnetic resonance imaging (MRI) and computed tomography (CT) data can also be integrated, facilitating complex ablation procedures…

The introduction of endovascular stent graft technology has ushered in a new era in therapy for diseases of the descending thoracic aorta. This ‘radical and revolutionary’ stent graft technology has been accompanied by simultaneous advances in non-invasive imaging and materials technology. The technical challenges of stent graft deployment in the descending thoracic aorta—such as proximity to the…

The use of iodinated contrast media (CM) for both diagnostic imaging and interventional studies continues to increase. The introduction of multi-detector computed tomography (MDCT) scanners allows for quicker imaging of internal organs, and image acquisition is now fast enough for study of the coronary arteries. This technology requires the delivery of a high concentration of iodine to the…

Atrial fibrillation (AF) and heart failure (HF) are two disease conditions that are intimately intertwined, both pathophysiologically and clinically. Currently, over 2.3 million people in North America and 4.5 million in the EU have AF, making it the most common arrhythmia encountered in clinical practice.1,2 It is expected that by 2050 there will be over 10 million people with AF.3 The estimated…

This article will attempt to cover the areas of historic background, current status, newer applications of existing tracers, attenuation correction, metabolic imaging, sympathetic imaging, new stress agents, molecular imaging, and positron emission tomography (PET) without on-site cyclotron. By no means is it meant to be inclusive of all that is currently happening but rather to illustrate some…

Coronary artery disease (CAD) represents the leading cause of morbidity and mortality in western countries. Many non-invasive stress tests are currently available for detecting CAD and assessing prognosis. Non-invasive stress techniques comprise exercise electrocardiographic (ECG) stress testing and imaging techniques, namely exercise/pharmacological stress echocardiography (SEcho) and exercise…

Cardiac imaging has become fully integrated in the management of patients, with echocardiography being the most widely used modality. Two-dimensional echocardiography (2DE) offers a detailed assessment of ventricular function, valvular pathology, and hemodynamics, but its comprehensiveness is limited by the fact that images represent a single plane, and may thus inadequately represent a heart…

Perception often lacks reality, and for many cardiologists and other physicians, the image and understanding of the nationÔÇÖs premier private organization dedicated to the prevention and treatment of heart disease and stroke is woefully out of date. For many physicians, the mission of the American Heart Association (AHA) is simply research, education, and advocacy, but it is much more than that…
