Circulation Journal has terminated receiving Case Report since 31st October 2008 with aims to grow the number of Impact Factor and speed up editorial procedures between acceptance and publication.

We are not able to receive new submission of Case Report from the end date, though ones received by then are treated in accordance with the old Instructions to Authors.

However, we will be pleased to accept contributions of potentially important clinical papers of several cases as Clinical Investigation or Rapid Communication.

We would very much appreciate your understanding and continued support for Circulation Journal.
