Excerpt
Cardiac magnetic resonance (CMR) is the noninvasive gold standard for evaluation of LV size/function due to its low interscan/intraobserver/interobserver variability. However, 2D echocardiography (Echo) remains the modality of choice to assess LV function due to ease of use, cost-effectiveness and ubiquity despite its known higher method variability. Randomized trials showed that automated implantable cardiac defibrillators (AICD) provide survival benefit in ischemic/nonischemic cardiomyopathy patients with LV ejection fraction (EF) ≤35%. It is therefore important to correctly classify patients by LVEF≤35% status to avoid improper placement or withholding of placement of AICD. We aim to quantify the misclassification of LVEF≤35% by Echo when compared to CMR in ischemic cardiomyopathy patients. …
