Describe the etiology.
Myocardial infarction (occurs in 8–15% of patients; 2 weeks to months after MI)
Risk factors [19]
Complete occlusion of the left anterior descending coronary artery
Female sex
Describe the location.
∼ 85% in the anterior or apical walls, 10–15% in the inferior-basal walls of the left ventricle
List clinical features.
Enlarged heart on percussion
Diffuse and displaced apical pulse to left midclavicular line
3rd and 4thheart sounds
Systolic murmur (mitral regurgitation)
List diagnostics.
ECG: persistent ST elevation
Echocardiography (or CT or MRI ): dyskinetic wall motion and diastolic deformity
List complications.
Arrhythmias
Ventricular rupture → cardiac tamponade
Thrombus formation → thromboembolism (stroke, mesenteric ischemia, renal infarction)
Heart failure
Describe the treatment.
Small and asymptomatic: conservative treatment with regular follow-up
If large, symptomatic, or there is evidence of a thrombus
ACE inhibitors
Anticoagulation
If not responsive to medical therapy: surgical resection of the aneurysm
