Postinfarction mechanical complications

: Treatment for acute myocardial infarction changed with improvement of coronary intervention. Most of acute myocardial infarction can be treated by coronary intervention, and number of emergent coronary artery bypass cases decreased. But, treatment of postinfarction mechanical complication is impossible by catheter intervention, and emergent surgical treatment is necessary. Major postinfarction mechanical complications are cardiac rupture, ventricular septal rupture and papillary muscle rupture. Results of surgical treatment for postinfarction mechanical complications are not satisfactory and early diagnosis and early surgical treatment can improve treatment outcome.
