Inherited Wolff‐Parkinson‐White Syndrome

Inherited Wolff‐Parkinson‐White Syndrome Authors: Liu, Yang; Xue, Yumei; Wu, Shulin; Hu, Dan Wolff‐Parkinson‐White (WPW) syndrome is a congenital disorder of cardiac conduction system characterized by electrocardiographic preexcitation and episodes of paroxysmal supraventricular tachycardia. It is caused by a cardiac developmental defect in the electrical insulation between the atria and the ventricles due to the presence of an accessory […]

Subcutaneous Implantable Cardioverter-Defibrillator

The Subcutaneous Implantable Cardioverter-Defibrillator: A Practical Review and Real-World Use and Application Authors: Panna, Mark E.; Miles, William M. The subcutaneous implantable cardioverter-defibrillator (ICD) is a novel technology using a subcutaneous (extrathoracic) system for treatment of potential lethal ventricular arrhythmias. It avoids many of the risks of transvenous ICD implantation. It may be considered in […]

Athletes and Arrhythmias

Athletes and Arrhythmias Authors: Jansen, Michael J.; Burke, Floyd W. Sudden cardiac death related to athletic competition is a rare but tragic event. The victims are typically young with no previous cardiovascular symptoms or limitations. The majority of sudden cardiac death events in athletes are due to ventricular arrhythmias as a result of underlying molecular and/or […]

Implantable Cardiac Defibrillators: Who Needs Them and Who Does Not?

Implantable Cardiac Defibrillators: Who Needs Them and Who Does Not? Author: Conti, C. Richard Cardiologists who see patients on a general cardiology service are beginning to see an increasing number of patients who have received a primary prevention implantable cardiac defibrillator (ICD) but have never had it fire. There are additionally a number of patients […]

Mechanical Circulatory Support for the Failing Heart

Mechanical Circulatory Support for the Failing Heart: Which Device to Choose Authors: Ahmed, Mustafa; Alvarez, Rene Critical cardiogenic shock remains a problem with staggering mortality, with the best hope of survival depending on timely and aggressive intervention. This often requires the use of extracorporeal mechanical support in addition to vasoactive medications to manage patients through their […]

Continuous Flow Left Ventricular Assist Device Therapy

Continuous Flow Left Ventricular Assist Device Therapy: A Focused Review on Optimal Patient Selection and Long-Term Follow-up Using Echocardiography Authors: Vilaro, Juan R.; Szady, Anita; Ahmed, Mustafa M.; Dawson, Jacqueline; Aranda, Juan M. Despite widespread awareness and use of scientifically proven life-prolonging medical and device-based therapies over the last two decades, heart failure remains a leading cause of morbidity, […]

Cardiac Resynchronization Therapy

Cardiac Resynchronization Therapy in 2015: Lessons Learned Authors: Ketha, Siva; Kusumoto, Fred M. Over 20 years of research has led to the now widely accepted role of cardiac resynchronization therapy (CRT) in medically refractory, mild to severe systolic heart failure (HF) with increased QRS duration. In addition to conferring a mortality benefit, CRT has been shown […]

Pulmonary Arterial Hypertension

Pulmonary Arterial Hypertension and the Failing Ventricle: Getting It Right Authors: Mandras, Stacy A.; Oleck, Sylvia; Ventura, Hector O. Right ventricular failure (RVF) remains the primary cause of death in patients with pulmonary arterial hypertension. We review the pathophysiology of RVF, including the remodeling and ventriculoarterial uncoupling that occurs when the failing right side of the heart […]

Evaluation of the Heart Failure Patient by Echocardiography

The Evaluation of the Heart Failure Patient by Echocardiography: Time to go beyond the Ejection Fraction Authors: Dowe, Jacqueline Dawson; Vilaro, Juan; Hamilton, Karen; Szady, Anita; Aranda, Juan M. Heart failure is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood. […]

Noninvasive Hemodynamic Monitoring for Heart Failure

Noninvasive Hemodynamic Monitoring for Heart Failure: A New Era of Heart Failure Management Authors: Hernandez, Gabriel A.; Navas, Viviana; Chaparro, Sandra Despite the development of noninvasive tools as echocardiography, right-sided heart catheterization remains an integral part of the cardiovascular evaluation. In the last decade, better understanding of the hemodynamic process before heart failure decompensation led to improvement […]
