Peripheral arterial disease
KEY POINTS • PAD is prevalent and associated with high morbidity and mortality but is frequently underdiagnosed. • Conventional approaches to diagnosis, including ABI and angiography (invasive and noninvasive), can…
Patient with mechanical dyssynchrony
KEY POINTS • Mechanical dyssynchrony relates to a delay in the timing of the contraction (systolic) or relaxation (diastolic) within the LV or between the RV and LV. • Mechanical…
Aortic stenosis and bioprosthetic valve degeneration
KEY POINTS • Transthoracic echocardiography and CT-AVC are the current mainstream modalities for aortic stenosis evaluation, but PET imaging is emerging as a novel molecular imaging technique for assessing disease…
Patients undergoing cancer treatment
KEY POINTS • Radionuclide and multimodality imaging are essential to the care of patients at risk for incident cardiovascular disease during or after cancer treatment, either because of preexisting cardiovascular…
Molecular imaging of myocardial infarction and remodeling
KEY POINTS • Nuclear cardiology currently evolves from assessing physiologic function and perfusion toward an interrogation of molecular pathways and pathophysiologic alterations at a (sub)cellular level. • Given a biphasic…
Patient with known or suspected cardiac sarcoidosis
KEY POINTS • Clinical manifestations of CS include heart block, ventricular arrythmias, SCD, and HF. • Among patients with biopsy-proven or a clinical diagnosis of extracardiac sarcoidosis, any signs or…
Patients with known or suspected amyloidosis
KEY POINTS • Cardiac amyloidosis is often underdiagnosed, misdiagnosed, or diagnosed late in the natural course of the disease. • Accurate diagnosis and typing of cardiac amyloidosis are both critical…
Novel approaches for the evaluation of arrhythmic risk
KEY POINTS • Current conventional methods to assess arrhythmic risk, including their guidance for implantation of a cardioverter defibrillator, have recognized shortcomings. • Radionuclide imaging can enhance other methods to…
Screening for transplant vasculopathy
KEY POINTS • CAV remains a major limitation for the long-term success of cardiac allografts. • The high prevalence of renal dysfunction has limited the use of invasive coronary angiography….
Patient with ischemic heart failure: Ischemia and viability assessment and management
KEY POINTS • In HF patients, CAD may be causal, contributory, or coincidental. The determination of the role of CAD in the patient’s cardiomyopathy is essential to determine the potential…
