冠(状动)咏球囊成形术(CBA)后数月内,再狭窄率高达12～34％,为其一大缺点。冠脉楔嵌压(CWP)的定义为:球囊置于狭窄处并加压(至2个大气压),此时导管顶端测得狭窄远端冠脉平均压,这就是CWP。一般认为CWP不但反映实际存在(可见)的侧枝血供,而且反映潜在备用(不可见)的侧枝血供。测定CWP之前,静脉注入或者口服硝酸酯类药物。以仰卧位胸腔前后经上3/4处为零点,CWP测值以5的整倍数表示。连续152例患者170文狭窄冠脉经CBA治疗成功后7±3个月,91例患者100支狭窄冠脉接受
Within a few months after crown balloon surgery (CBA), the restenosis rate is as high as 12 to 34%, a major drawback. Coronary Wedge Pressure (CWP) is defined as the balloon being placed in a stenosis and pressurized (up to 2 atm) when the distal tip of the catheter measures the average pressure of the stented distal coronary artery, which is CWP. CWP is generally considered to reflect not only the actual (visible) blood supply to the side branches, but also the potential for standby (invisible) blood supply to the side branches. Before the determination of CWP, intravenous or oral nitrates. To supine position thoracic before and after the 3/4 at zero, CWP measured value of 5 multiples expressed. A consecutive 152 patients with stenosis of 170 cases of CBA after successful 7 ± 3 months, 91 patients with 100 stenosis coronary artery received
