Which of the following factors does/do not increase early mortality associated with repair of left ventricular aneurysm?

B. Size of aneurysm.

E. Location of aneurysm.

DISCUSSION: Class IV cardiac status and emergent operation both imply extensive myocardial damage and in most reported series are associated with increased operative mortality. Similarly, the presence of significant stenosis of the left main coronary artery increases the operative mortality of virtually all cardiac procedures. On the other hand, neither the size of the aneurysm nor its location affect early operative mortality, despite the fact that posterior aneurysms are technically more difficult to repair and are much less common.
