An under‐recognized phenomenon: Myocardial volume change during the cardiac cycle

Background Myocardial volume is assumed to be constant over the cardiac cycle in the echocardiographic models used by professional guidelines, despite evidence that suggests otherwise. The aim of this paper is to use literature-derived myocardial strain values from healthy patients to determine if myocardial volume changes during the cardiac cycle. Methods A systematic review for studies with longitudinal, radial, and circumferential strain from...
