Results: M-mode echocardiograms showed ventricular contractile dysfunction with reduced aortic blood flow in AVF mice, whereas STS treatment prevented the decline in cardiac function.
Methods 50 cases undergone the stentless bioprosthese replacement were investigated using digitizing of both ventricular long axis M mode echocardiograms before and 1, 6,12 and 24 months after AVR.
