Fig 1 Incidence of late postoperative embolic stroke after valve replacement, by implant site and prosthesis type. The incidence of stroke was significantly higher in patients with mitral mechanical valves than in those with other types of implants. (*p = 0.002). — = aortic bioprotheses; · · · = mitral bioprostheses; – – = aortic mechanical; - · - · = mitral mechanical. (Bio = bioprostheses; Mech = mechanical prostheses.)

Fig 2 Risk-adjusted effect of increased preoperative left ventricular grade on late postoperative embolic stroke in patients who underwent mitral valve replacement. With each unit increase in preoperative LV grade, a linearized stroke risk augmentation of 61% was observed. (LV = left ventricular.)
