Chronic heart failure (CHF) is a major public health problem in industrialized societies with an incidence approaching 10 per 1,000 population after age 65 and an age-dependent prevalence of less than 1% between ages 45-55, 2-5% between ages 65-75, and approximately 10% for patients aged 80 years or more.Thus, HF is primarily a condition of the elderly and approximately 80% of patients…

Implantable cardioverter–defibrillators (ICDs) are being implanted in an ever-increasing number of patients at risk for sudden cardiac death. To ensure the efficacy of the defibrillation system, step-down defibrillation threshold (DFT) testing has traditionally been used to ensure that the ICD can appropriately detect and terminate clinical ventricular fibrillation (VF).
Currently, the most…

Mitral regurgitation (MR) is common in industrialized countries, with a prevalence of about 2% in the general population and about 9% in people over 75 years old.1,2 MR is classified as primary/degenerative when it results from a structural abnormality of the valve apparatus, or secondary/functional when it results from a disturbance of ventricular or annular geometry and/or function that impairs…

Congenital heart disease affects approximately 0.8% of the population.1 It is also estimated that there are approximately one million adults in the US living with some form of congenital heart disease.2 In daily practice, echocardiography is the most widely used imaging modality for diagnosis and evaluation of these patients. As medical technology has developed, this modality has continuously…

Despite significant improvements for earlier detection of and medical therapies for heart failure, a recent American Heart Association (AHA) study stated that the actual incidence of heart failure has not declined. Of interest is the fact that the AHA found hypertension precedes development of heart failure in 91% of cases. The increasing prevalence of these combined disease states escalates the…

2D echocardiography (2DE) is a common diagnostic and treatment planning tool in clinical cardiology, especially for the assessment of left ventricular (LV) volume and function. However, traditional 2DE is severely limited by its dependence on geometrical assumptions, which can lead to inaccuracies in volume quantification.1 Because 3D echocardiographic (3DE) imaging eliminates geometrical…

Despite important therapeutic improvements in pharmacological and device therapies, the prognosis for patients with advanced cardiovascular disease is poor, even with optimal pharmacological and device management. Heart failure continues to be a major cause of morbidity and mortality in the US. It is the leading medical cause of hospitalization and is expected to result in an estimated direct and…

Introduction
Premature ventricular complexes (PVCs) in the absence of underlying structural heart disease have long been viewed as benign. Early studies with small population sizes and limited cardiac testing suggested that long-term prognosis in patients with idiopathic PVCs is similar to those in patients without other cardiac disease, and treatment was consequently limited to provide…
