Pericardial Pseudodiverticulum or Pseudoaneurysm due to Rupture of a Cardiac Aneurysm into the Pericardial Sac 48 Years after the First Description.

A typical sequential course becomes apparent from the clinical features, the electrocardiography, echocardiography, radiological changes as well as angiographic results. This ultimately leads to an unusual complication of transmural myocardial infarction, i.e. the development of a pericardial pseudodiverticulum (less aptly described as pseudoaneurysm or false aneurysm). A timely cardiosurgical intervention may avert the otherwise fatal outcome. Copyright © 2004 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
