We compared two bovine pericardium prostheses (Sorin Freedom versus Carpentier-Edwards Perimount) in patients with small aortic annulus, randomizing 80 patients affected by prevalent aortic stenosis and studying the residual gradient, the effective orifice area, the left ventricular mass regression and the ventricular function to evaluate the cost-benefit in terms of risk-advantages for the patient.
我们比较了两种牛心包人工瓣膜（索林自由瓣与卡朋蒂埃-爱德华兹普瑞蒙特瓣）在小主动脉瓣环患者中的应用情况，将80例患有重度主动脉瓣狭窄的患者随机分组，并研究残余压差、有效瓣口面积、左心室质量消退情况以及心室功能，以评估对患者而言在风险-获益方面的成本效益。
