摘要
本文报告２６７例，２７０次心脏瓣膜病换瓣术前冠状动脉造影结果。患者中男性１８１，女性８６例，平均年龄５４．４岁。１５．４％的患者合并５０％以上的冠状动脉狭窄，９．７％的患者换瓣同时需行搭桥手术或因冠状动脉病变太重不宜手术治疗。本组冠状动脉狭窄的发生率随年龄而增加，男性多于女性。分析表明，瓣膜病患者的胸疼多因主动脉瓣病变（尤其是狭窄）引起，不能反映患者有无冠状动脉病变。术前常规冠状动脉造影对提高手术成功率甚为重要，５０岁以上的国人患者都应进行这一检查。笔者还讨论了瓣膜病患者冠状动脉造影的操作特点，左室造影所见和左房血栓征象的临床意义。
The result of preoperative coronary angiography in 267 patients with valvular disease was reviewed.There were 181 males and 86 females with mean age of 54.4 years.Significant coronary atherosclerotic lesions-that is,stenoses equal to or greater than 50 percent of luminal diameter-were found in 41 patients(15.4 percent).Subsequent surgery was perforrned in 229 cases and 21 of tmem(9.7 percent) underwent bypass graft and valve replacement simultaneously. In our series chest pain more often occurred in patients with aortic lesion, No relation was found between the incidence of coronary and aortic valve diseases. For the purpose of excluding the presence of coronary disease,we recommend that.coronary angiography should be performed befor valve replacernent,if the patient is above 50 years of age.
