The editorial team of Circulation Journal has recently confirmed that the case report written by Guo H et al, published in Nov 2006 issue of Circulation Journal (Circ J 2006; 70: 1520-1522), is a duplicate publication, obviously violating the following "Instructions to Authors": Submission of a manuscript to the Circulation Journal implies that the article is original and that no portion (including figures or tables) is under consideration elsewhere or has been previously published in any form other than as an abstract. Previous publication includes publishing as a component of symposia, proceedings, transactions, books (or chapters), articles published by invitations or reports of any kind, as well as in electronic data bases of a public nature. Therefore, we have decided to retract the paper from Circulation Journal.
As Editor-in-Chief, I regret the time that the peer reviewers and others spent evaluating this paper. I sincerely hope that this type of problems will never happen in the future.
