Flowchart of patient selection and assessment of septal flash volume. a Flowchart of patients selected for the study. *Exclusion criteria: greater than mild valvular disease, myocardial infarction, obstructive coronary artery disease (stenosis > 75%), positive stress test, cardiomyopathy, arrhythmia, prior cerebrovascular events and history of potential cardiotoxic chemotherapy exposure. CMR—cardiovascular magnetic resonance, LBBB—left bundle-branch block. b Representative image of assessment of flash volume using CMR short axis (SAx). Area within blue line: end-systolic volume, green area: corrected end-systolic volume by assuming a homogenous circumferential wall thickening, red area: flash volume
