ReviewCardiac disease and heart failure in cancer patients: is our training adequate to provide optimal care?
The care of patients with cancer who have cardiac disease is dispersed both sequentially and concurrently across multiple providers, and an important goal of education is communication among the providers regarding change of therapy, toxicity of therapy, and symptom assessments. Changes must be made to improve the delivery of cardiac care in patients with cancer and cancer survivors. Therefore, the authors propose a multilevel approach that includes short, targeted curriculum for housestaff training programs in internal medicine, family medicine, pediatrics, cardiology and oncology; increasing presence at national meetings of internists, oncologists and cardiologists; and an Internet-based repository of core information.

In the United States, 250,000 people die from a cardiac arrest every year. Despite a well established emergency medical response system, survival from out-of-hospital cardiac arrest remains poor in United States cities. Paramount to achieving successful resuscitation of a cardiac arrest victim is provision of early defibrillation. ⋯ In 1995, the American Heart Association challenged the medical industry to develop a defibrillator that could be placed in public settings, used safely by lay responders, and provide earlier defibrillation to cardiac arrest victims. Over the last decade, there have been significant technological advancements in automated external defibrillators (AEDs), and clinical studies have demonstrated their benefits and limitations in various public locations. This article discusses the technologic features of the modern AED and the current data available on the use of AEDs in public settings.

ReviewThe role of ventricular tachycardia ablation in the reduction of implantable defibrillator shocks.
Frequent shocks from an implantable defibrillator (ICD) can have adverse cardiac affects and lead to increased pain, anxiety, and a decreased quality of life. Pharmacologic attempts and ICD reprogramming strategies aimed at reducing ICD shocks have modest results, with frequent discontinuation of medicines because of side effects. Ventricular tachycardia (VT) ablation is recommended in the treatment of patients with frequent ICD shocks caused by VT. VT ablation may also be considered in patients with an initial ICD shock and as prophylactic treatment in patients with a history of sustained VT who are undergoing ICD implant.

ReviewTreatment with iron of patients with heart failure with and without anemia.
Iron deficiency is a common cause of anemia in otherwise healthy individuals and plays an important role in the development of anemia within the heart failure patient population. Iron-deficient heart failure patients experience worse symptoms and are less exercise tolerant than those without iron deficiency. These symptoms may occur even before clinical anemia is evident. This article reviews studies of the benefits of the use of intravenous iron to treat iron deficiency in anemic and nonanemic heart failure patients and an overview of the physiology and pathophysiology of iron metabolism in chronic heart failure.

ReviewMagnetic resonance imaging of pericardial disease and intracardiac thrombus.
Magnetic resonance is known to be a superior modality for the evaluation of pericardial disease and intracardiac masses because of its unmatched capacity for tissue characterization and high spatial resolution. New real-time sequences complement the standard morphologic imaging of the pericardium with dynamic image acquisitions that also can provide hemodynamic information indicative of constriction. Magnetic resonance also is becoming increasingly recognized as a superior modality for the detection and characterization of intracardiac thrombus. This article reviews the use of magnetic resonance imaging for the evaluation of pericardial disease and the detection of intracardiac thrombus, with particular emphasis on the newer pulse sequences currently available for cardiac imaging.
