Flow-sensitive 4D MRI was performed to visualize the complex blood flow in the left ventricle (LV), atrium and out-flow tract. Left atrial and LV vortex formation was seen in older and younger volunteers. The left pulmonary veins promote more pronounced vortexes in older and younger volunteers during systole and diastole. Intraventricular vortex formation was not different between older and younger individuals with most vortexes located in basal and midventricular parts of the LV. The knowledge of blood flow in the healthy heart is essential for further patient studies in cardiac disease such as LV aneurysms, valve insufficiencies or atrial arrhythmia.
