Objective To evaluate the effects of various myocardial protections on the rate of myocardial oxygen uptake in patients undergoing mitralandaorticvalvereplacement (double valve replacement, DVR).
目的了解不同心肌保护方式对二尖瓣和主动脉瓣双瓣膜置换手术心肌氧摄取率的影响。
2
Mitral valvoplasty in 2 patients andmitralvalvereplacement in 9 andaortic valve replacement in 3 and double valve replacement in 10 were performed.
全组行二尖瓣成形术2例,二尖瓣置换术9例,主动脉瓣置换术3例,二尖瓣、主动脉瓣双瓣膜置换术10例;
3
Left atrial, left ventricular pressure curves andaortic blood flow curves were measured beret and after mitralvalvereplacement.
