In children and young adults, sudden cardiac death (SCD) occurs in approximately 1-2 per 100,000 population.1,2 While the overwhelming majority of occurrences of SCD occur in the adult population and are due to ischemic heart disease, very few cases in a pediatric population are. Pediatric SCD is a relatively uncommon occurrence whose underlying etiology often remains elusive. A long list of…

Idiopathic pulmonary arterial hypertension (formerly referred to as primary pulmonary hypertension) is an uncommon yet progressively fatal disease defined by the presence of mean pulmonary artery pressure greater than 25mmHg at rest or greater than 30mmHg with exercise as tested by right heart catheterization in the absence of other etiologies for pulmonary hypertension. Across several studied…

Prospective trials have demonstrated that flecainide, propafenone, quinidine, and sotalol are equally effective in preventing recurrences of atrial fibrillation (AF). A new twice-a-day formulation of propafenone has been demonstrated to have efficacy that is higher than the short-acting form of the drug. Dofetilide, although useful for terminating and preventing recurrence of persistent AF, has…

Cardiac resynchronization therapy (CRT) has achieved widespread approval as a safe and efficient therapeutic strategy for medically refractory congestive heart failure (CHF). The standard indications for CRT include patients with advanced heart failure and evidence of systolic dysfunction (ejection fraction [EF] ≤35%), conduction tissue disease (QRS duration ≥120ms), and marked cardiac symptoms …

The last 60 years have seen significant changes in the care of congenital heart disease for both pediatric and adult patients. Increasing patient survival rates have widened the number and scope of potential patients seen by congenital cardiologists.1 These patients often undergo multiple surgeries, particularly since few lesions are truly ‘repaired.’ The majority of patients will have residua or…

Transvenous catheter ablation has become a curative treatment for many arrhythmias. Knowing the precise catheter location in relation to true cardiac anatomy will benefit catheter ablation procedures. A novel electroanatomic mapping system (CartoMerge™, Biosense Webster) with the capability of integrating pre-procedural computed tomography (CT) or magnetic resonance (MR) images with…

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…

Mechanical circulatory support (MCS) devices are changing heart failure therapy. A spectrum of devices have become essential to the management of a variety of heart failure scenarios and, in the next few decades, this spectrum will expand and improve thousands of lives each year. The field has grown slowly and at considerable cost over the past 50 years but is now moving rapidly. Devices as small…
