The inner wall of the aneurysm retains its trabeculations.
Mural thrombus is uncommon.
Calcification may occur in the adherent pericardium.
Most posterior aneurysms are true aneurysms.
Most patients with left ventricular aneurysms have single vessel LAD disease.
Question 2: Which of the following statements is true regarding the clinical features and diagnosis of post-infarct left ventricular aneurysm?
Akinesia or dyskinesia on catheterization is diagnostic of left ventricular aneurysm.
Most aneurysms present with dyspnea.
Large aneurysms may continue to increase in size up to 1 year.
Total occlusion of the LAD is a determinant of aneurysm formation.
Thrombolytic therapy of acute myocardial infarction has not changed the incidence of these aneurysms.
Question 3: Which of the following statements is true regarding operative management of post-infarct left ventricular aneurysm?
Concomitant coronary artery bypass is not usually indicated in these patients.
Retaining some of the smooth aneurysm endocardium helps prevent postoperative clot formation.
Septal aneurysmal tissue should not be resected as part of a Dor repair.
Large asymptomatic aneurysms can be managed non-operatively.
Direct linear closure can be used for small or moderate sized aneurysms.
Question 4: Which of the following statements is true regarding results of post-infarct left ventricular aneurysm surgery?
5-year survival following operative repair is approximately 65%.
Most early deaths are from intractable ventricular arrhythmias.
Survival is not affected with complete revascularization.
Symptomatic improvement is correlated with improved postoperative left ventricular function.
Paradoxical motion in border segments is unaffected by aneurysm resection.
Question 5: Which of the following statements is true regarding other types of left ventricular aneurysms?
False aneurysms are less likely to rupture than true aneurysms.
Congenital aneurysms can be resected without cardiopulmonary bypass.
Patients with free wall rupture are poor surgical candidates.
Post-traumatic aneurysms should be observed until significant arrhythmias develop.
False aneurysms most commonly occur along the lateral wall of the left ventricle.
