Cardiovascular Magnetic Resonance to Guide Defibrillator Implantation for LVEF of 36% to 50%
Joseph B. Selvanayagam, John G. F. Cleland, Graham S. Hillis, Sivabaskari Pasupathy et autres
Importance: Current guidelines do not recommend primary prevention implantable cardioverter-defibrillators (ICDs) unless a patient's left ventricular ejection fraction (LVEF) is 35% or less. Many sudden cardiac deaths (SCD) occur when LVEF is 36% to 50%. Myocardial scar (a key arrhythmic substrate) can …
