The Role of Focused Echocardiography in Pediatric Intensive Care: A Critical Appraisal

Figure 1

Calculation of left ventricular fractional shortening by the M mode. (a) Parasternal short-axis view in a patient with normal ejection fraction. (b) Parasternal long-axis view in a patient with viral myocarditis and cardiogenic shock, with reduced ejection fraction. EDD: left ventricle end-diastolic diameter; ESD: left ventricle end-systolic diameter; RV: right ventricle. FS = EDD − ESD/EDD × 100.
