目的探索经皮激光心肌打孔血运重建术（ＰＭＲ）中左心室造影定位方法。方法应用不同的记录模式对１２例行ＰＭＲ治疗的病患者进行左心造影打孔区定位检查。结果１２例冠心病患者ＰＭＲ治疗均获成功，无任何并发症发生。结论①左心室造影中６例应用ＣＳＰ模式记录，６例应用ＤＣＩ＋ＭＡＰ模式记录，均可记录到满意的左心室双期图像。②ＰＭＲ术中利用左心室腔轮廓和骨性结构标志进行定位时，ＤＣＩ＋ＭＡＰ模式优于ＣＳＰ模式。③每次造影以造影剂总量３５ｍｌ、速度１２～１７ｍｌ／ｓ、压力７５０ＰＳＩ为宜。造影剂，最好选用非离子型。④选择高压注射器的Ｒ波触发造影，可减少造影过程中心律失常的发生，提高造影的成功率。⑤投照角度固定应用双斜位，右前斜位３０度，左前斜位６０度，可便于手术前后对比及影像的计算机后处理
Objective To explore the method of left ventricular angiography in percutaneous laser myocardial perforating revascularization (PMR). Methods Using different recording modes, 12 cases of PMR-treated patients were examined by left ventricular angiography. Results PMR in 12 patients with coronary heart disease was successful without any complications. Conclusion ① Six cases of left ventricular angiography were recorded by CSP mode and six cases were recorded by DCI + MAP mode. Both images of satisfactory left ventricular phase were recorded. (2) DCI + MAP model was superior to CSP model when using left ventricular cavity contour and bony structure markers in PMR. ③ each angiography with a total amount of contrast agent 35ml, speed 12 ~ 17ml / s, pressure 750PSI appropriate. Contrast agent, the best choice of non-ionic. ④ Select the R-wave high pressure syringe trigger angiography can reduce the incidence of arrhythmia during angiography to improve the success rate of angiography. ⑤ projection angle fixed dual oblique position, the right anterior oblique 30 degrees, 60 degrees left anterior oblique, can facilitate the contrast before and after surgery and computer image processing
