Implantable cardioverter defibrillator outcome: beyond ejection fraction?
Over three decades of clinical experience have brought evidence that implantable cardioverter defibrillators (ICDs) should be considered as ‘gold standard’ therapy in prevention of sudden cardiac death. Implantable cardioverter defibrillators are currently indicated for secondary prevention in patients after cardiac arrest and life-threatening ventricular tachyarrhythmias or for primary prevent...
متن کاملEffect of Preoperative Ejection Fraction
Ninety-three patients with aortic valve disease were evaluated to determine the effect of the preoperative left ventricular ejection fraction (EF) on the results of aortic valve replacement (AVR). Forty-six patients had aortic stenosis (AS), 16 had aortic insufficiency (Al), and 31 had mixed aortic stenosis and insufficiency (MX). Immediate and long-term survival curves in AS and MX, and in AS ...
متن کاملCardiac structural predictors of ventricular tachycardia…looking beyond ejection fraction and ventricular scar
Background Each year, about 424,000 adults experience sudden cardiac death (SCD) in the United States. Assessment for cardiac structural anatomy is vital in this population. While left ventricular ejection fraction (LVEF) is an established predictor of ventricular tachycardia (VT), it is known that VT occurs in nonischemic patients, with normal LVEF. Contribution of ventricular scar is also und...
متن کاملLV mechanics in mitral and aortic valve diseases: value of functional assessment beyond ejection fraction.
The assessment of myocardial function in the context of valvular heart disease remains highly challenging. The myocardium deforms simultaneously in 3 dimensions, and global left ventricular (LV) function parameters such as volume and ejection fraction may remain compensated despite the changes in myocardial deformation properties. Current guidelines recommend valve replacement/repair in the pre...
متن کاملStrain Improves Risk Prediction Beyond Ejection Fraction in Chronic Systolic Heart Failure
BACKGROUND The utility of longitudinal, circumferential, and radial strain and strain rate in determining prognosis in chronic heart failure is not well established. METHODS AND RESULTS In 416 patients with chronic systolic heart failure, we performed speckle-tracking analyses of left ventricular longitudinal, circumferential, and radial strain and strain rate on archived echocardiography ima...
