TY - CHAP M1 - Book, Section TI - Surgical Treatment of Complications of Myocardial Infarction, Ventricular Septal Defect, Myocardial Rupture, and Left Ventricular Aneurysm A1 - Glower, Donald D. A2 - Cohn, Lawrence H. A2 - Adams, David H. Y1 - 2017 N1 - T2 - Cardiac Surgery in the Adult, 5e AB - Acute myocardial infarction can require surgical intervention for many reasons. Most commonly, patients may have coronary artery stenosis that may be amenable to coronary artery bypass grafting, either to halt the progress of the acute infarction, or to prevent subsequent angina, reinfarction, or death (see Chapters 20 to 25). Myocardial infarction can also result in refractory congestive heart failure and/or circulatory shock due to inability of the left and/or right ventricles to maintain the cardiovascular circulation. These patients may benefit from ventricular replacement therapy that include cardiac transplantation (see Chapter 61), extracorporeal membrane oxygenation (see Chapter 19) or placement of left and/or right ventricular assist devices (see Chapter 63). Acute myocardial infarction can have a number of other mechanical consequences that may need to be addressed surgically. These can include acute and chronic ischemic mitral regurgitation and even papillary muscle rupture (see Chapter 38) and functional tricuspid regurgitation (see Chapter 44). Three final and potentially catastrophic mechanical complications of acute myocardial infarction are addressed in this chapter and include postinfarction ventricular septal defect, cardiac rupture, and left ventricular aneurysm.
