Over the past 35 years, treatment of coronary artery disease and acute coronary syndrome has changed drastically. Balloon angioplasty offered an early mechanical solution but carried a high risk for acute complications and subsequent restenosis, mainly from recoil. The bare metal stent (BMS) improved restenosis because of recoil, but still carried a relatively high rate of restenosis because of… View more

Intravascular Ultrasound-guided Versus Angiography-guided Percutaneous Coronary Intervention: Evidence from Observational Studies and Randomized Controlled Trials
Author(s): Xiao-Fei Gao , Xiang-Quan Kong , Guang-Feng Zuo , et al Added: 3 years ago
Coronary angiography is widely used to diagnose coronary artery disease and to guide percutaneous coronary intervention (PCI). However, 2D projection angiography cannot completely reflect the 3D coronary lumen, with several inherent limitations in evaluating plaque composition, vessel diameter, diffuse reference vessel disease, lesion severity, as well as the result of stent deployment. In the… View more

Cardiac computed tomography (CT) has evolved greatly over the last 20 years. This article reviews its current clinical uses, and describes some of the potential for even greater utility in the near future. Electron beam tomography (EBT) was developed 20 years ago specifically for cardiac imaging. Although the technique can quantify ventricular anatomy and function as well as myocardial perfusion… View more

Protocol Fundamentals for Coronary Computed Tomography Angiography
Author(s): Frank J Rybicki Added: 3 years ago
Most advances in cardiac computed tomography (CT), particularly coronary CT angiography (CTA), have come from the development of protocols consistent with rapid incremental improvements in CT technology. The evolution of cardiac CT from early technology has been paralleled with evolving protocols that have extended cardiac CT beyond the imaging of coronary arteries alone: current applications… View more

Positron emission tomography (PET) has contributed significantly to advancing our understanding of heart physiology and pathophysiology for more than 25 years. Despite its clear success in research applications, the restricted availability of this technology, its increased cost and limited data supporting its use and reimbursement have all contributed to the relatively limited clinical acceptance… View more

Cardiovascular disease (CVD) afflicts greater than 70 million patients in the US alone, and accounts for over half of all deaths. Non-invasive cardiac imaging modalities are used to provide enhanced methods of diagnosis of CVD, guidance of patient-specific therapy, and prognostication of cardiac-related risk. Non-invasive cardiovascular imaging has traditionally been stratified into two distinct… View more

Accurate quantification of ventricular volumes and function is important for the assessment and management of patients with suspected ischemic and non-ischemic cardiomyopathies. 2D echocardiography is widely used for qualitative and semi-quantitative assessment of cardiac size and function. However, 2D echocardiography has limited accuracy, particularly in patients with regional variability in… View more
