Long-term survival after surgical treatment for post-infarction mechanical complications: results from the Caution study
Authors' conclusion
Contemporary data from a multicentre cohort study show that surgical treatment for post-AMI MCs continues to be associated with high in-hospital mortality rates. However, long-term survival in patients surviving the immediate post-operative period is encouraging.
