Aortic valve opening and closure: the clover dynamicsKeywords: Aortic valve, aortic root, anatomy, physiology, aortic valve repair Abstract: Systolic aortic root expansion is reported to facilitate valve opening, but the precise dynamics remain unknown. A sonometric study with a high data sampling rate (200 to 800 Hz) was conducted in an acute ovine model to better understand the timing, mechanisms, and shape of aortic valve opening and closure
