PY - 2012 T2 - Cardiac Surgery in the Adult, 4e AB - Left ventricular aneurysm has been strictly defined as a distinct area of abnormal left ventricular diastolic contour with systolic dyskinesia or paradoxical bulging (Fig. 30-1).1,2 Yet, a growing number of authors favor defining left ventricular aneurysm more loosely as any large area of left ventricular akinesia or dyskinesia that reduces left ventricular ejection fraction.3–5 This broader definition has been justified by data suggesting that the pathophysiology and treatment may be the same for ventricular akinesia and for ventricular dyskinesia.4,6 However, recent studies suggest that the optimal treatment and outcomes of patients with akinetic segments versus dyskinetic segments might be different.7,8 Intraoperatively, a left ventricular aneurysm may also be identified as an area that collapses upon left ventricular decompression.3,6,9 True left ventricular aneurysms involve bulging of the full thickness of the left ventricular wall, whereas a false aneurysm of the left ventricle is, in fact, a rupture of the left ventricular wall contained by surrounding pericardium.
