The original version of this article, originally published online ahead of printing on January 05, 2018, unfortunately contained mistakes.

In the section Conclusions (although these statements were correct in the section Abstract and Key Points), the fourth sentence should read as follows: compared with non-REMs, REMs were associated with a lower level (not REMs were associated with a higher level).

In the section Discussion, Advantages of CTA over CA, the first sentence should read as follows: Patients with PA-VSD-MAPCAs (not Patients with PA-VSCAD-MAPCAs)

In addition, in the section Funding, we missed “Medical Scientific Research Foundation of Guangdong Province of China (no. A2018039)” before the sentence "National 11th and 12th Five Year Support Projects of China (no. 2006BAI01A08 and 2011BAI11B22)".

The authors deeply apologize for these mistakes.
