主动脉瓣返流(AR)和二尖瓣返流(MR)同属容量负荷过度型病变,然而换瓣术的预后明显不同。在大致相等的容量负荷下,AR患者左室射出返流血液受到的阻抗大于 MR患者。经体检和超声心动图检查确诊 AR 和MR,多普勒超声检查判明至少中度返流,并
Aortic valve regurgitation (AR) and mitral regurgitation (MR) belong to the volume overload over-type lesions, however, the prognosis of valve replacement is significantly different. At approximately equal volumetric loading, AR patients have more resistance to left ventricular ejection-current blood than MR patients. AR and MR diagnosed by physical examination and echocardiography, Doppler ultrasound examination showed at least moderate reflux, and
