Coronary angioplasty (PTCA) is now applicable to selected patients with multiple vessel disease, total occlusions, tandem lesions and complex branch disease. Operator experience and skill contribute to a high success rate in complex anatomy, but equally important is appropriate case selection based on angiographic review of lesion morphology, branches, extent of coronary artery disease, and left ventricular function. Likewise, during and after the procedure similar angiographic assessment is important to determine resultant lesion morphology, branch anatomy, distal runoff, and adequacy of lesion dilatation. Thus, the outcome of angioplasty is dependent on the operator's ability to opacify the coronary arteries with minimal or no vessel/lesion overlap or foreshortening. Although coronary angiography has become more routine for many angiographers with the advent of angioplasty, the importance of high-quality angiography continues to be a major component for successful angioplasty.
冠状动脉血管成形术（PTCA）目前适用于患有多支血管病变、完全闭塞、串联病变和复杂分支病变的特定患者。术者的经验和技能有助于在复杂解剖结构中获得高成功率，但同样重要的是基于对病变形态、分支、冠状动脉疾病范围和左心室功能的血管造影评估进行恰当的病例选择。同样，在手术过程中和术后，类似的血管造影评估对于确定最终的病变形态、分支解剖结构、远端血流以及病变扩张的充分性也很重要。因此，血管成形术的结果取决于术者以最小或无血管/病变重叠或缩短的方式使冠状动脉显影的能力。尽管随着血管成形术的出现，冠状动脉造影对许多血管造影师来说已变得更加常规，但高质量血管造影的重要性仍然是成功进行血管成形术的一个主要因素。
