Ventricular Outpouchings - Differential Diagnosis
Recess has narrow neck and does not reach half of myocardial wall while crypt (or cleft) goes beyond half of the wall. In systole they obliterate. 
Diverticulum has narrow neck, coated by thinned vital myocardium and goes beyond the myocardial wall; during systole, it contracts but does not completely disappear. 
The Congenital Aneurysm has broad neck, coated by fibrous tissue with systolic dyskinesia. 
The pseudoaneurysm is due to myocardial ischemia with wall rupture and blood in pericardium. 
The Double-Chambered left ventricle is a rare congenital abnormality in which left ventricle has an anomalous septum or band
