to-date evidence-based review on specific topics. The articles begin with a historical perspective by Barry Maron, the godfather of hypertrophic cardiomyopathy. Next is “Atrial and Ventricular Arrhythmias in Hypertrophic Cardiomyopathy,” followed by “The Role of Cardiovascular Magnetic Resonance in Sudden Death Risk Stratification in Hypertrophic Cardiomyopathy,” “Relationship Between Arrhythmogenic Right Ventricular Dysplasia and Exercise,” and “Left Ventricular Hypertrophy and Arrhythmogenesis.” Subsequent articles focus on other cardiomyopathies, such as dilated cardiomyopathy, sarcoidosis; chagasic cardiomyopathy; viral myocarditis and pericarditis; Fabry cardiomyopathy; mitochondrial cardiomyopathy and related arrhythmias; arrhythmias in the muscular dystrophies; peripartum cardiomyopathy; left ventricular noncompaction; and

Cardiomyopathies constitute a large and diverse entity of myocardial, structural, and functional abnormalities. Hypertrophic cardiomyopathy is the most common abnormality with initially normal left ventricular cavity size and systolic function at one end of the spectrum and severe dilated nonischemic cardiomyopathy at the other end. Almost all cardiomyopathies have a genetic basis that causes myocardial disarray that sets a substrate for arrhythmias of different mechanisms. We are honored to have been invited as guest editors of this issue of Cardiac Electrophysiology Clinics dedicated to the “Arrhythmias in Cardiomyopathies.” It is an important topic and as such there is currently no collective resource on the subject, although many reviews and articles are available on individual topics. We are privileged that a group of leading authors have accepted our invitation and provided their up-

Preface Takotsubo cardiomyopathy. “QT Prolongation and Oncology Drug Development” is also included, with a final article on “Arrhythmia in Stem Cell Transplantation.” We are very pleased with the overall context of this issue and are confident that it will be useful to cardiology and electrophysiology fellows, cardiologists, and electrophysiologists as the most updated reference on this important topic, “Arrhythmias in Cardiomyopathies.” Mohammad Shenasa, MD Department of Cardiovascular Services O’Connor Hospital Heart and Rhythm Medical Group 105 North Bascom Avenue, Suite 204 San Jose, CA 95128, USA
