The Evolution of Intraventricular Vortex during Ejection Studied by Using Vector Flow Mapping

Aims: The purpose of this study was to assess the evolution of intraventricular vortex during left ventricular (LV) ejection. Methods: Vector flow mapping was performed in 51 patients with coronary artery disease and LV ejection fraction (EF) >50%, 70 patients with EF 50%, the intraventricular vo...

Zusammenfassung:	Aims: The purpose of this study was to assess the evolution of intraventricular vortex during left ventricular (LV) ejection. Methods: Vector flow mapping was performed in 51 patients with coronary artery disease and LV ejection fraction (EF) >50%, 70 patients with EF 50%, the intraventricular vortex dissipated quickly during early ejection. In patients with EF
