Background The left ventricular (LV) ejection fraction (EF) is a crucial parameter for the diagnosis and therapeutic management of heart failure. Due to its wide availability and its comprehensive use, echocardiography (EC) is the standard method for the assessment of the LV function in clinical routine. As fundamental clinical decisions, e.g. initiation of medical heart failure therapy or implantation of an ICD, are based on the EF, methods like the Simpsons or Teichholz formulas have been developed for its quantification in EC. Cardiovascular magnetic resonance (CMR) is the gold-standard for the evaluation of cardiac function but comparative data between CMR and EC is scarce. Therefore, we sought to compare the agreement of functional EC and CMR measurements in a daily routine clinical setting.
