The study is a prospective, randomized, controlled, exploratory trail to evaluate the strategy of "one-stop" endovascular treatment for concomitant coronary artery disease and aortic atherosclerotic disease.

60 patients will be allocated randomly in a 1:1 ratio into one-stop strategy group or staging strategy group. In one-stop strategy group, percutaneous coronary intervention (PCI) will be performed on the same operating room immediately after the endovascular aortic repair (EVAR); In staging strategy group, PCI will be performed several days after EVAR. The safety and effectiveness will be assessed between two groups 1 year after the operation. The economic index will be evaluated as well as.

• Aged from 18 years to 75years, male or female;
• Aortic atherosclerotic disease with indication of EVAR;
• Coronary heart disease with indication of PCI;
• Provided informed consent.

Exclusion Criteria:

• Acute aortic dissection
• Acute coronary syndrome
• Dysfunction of coagulation system
