LEFT VENTRICULAR TRUE ANEURYSM Figure 8-16 LEFT VENTRICULAR TRUE ANEURYSM A true aneurysm contains all three layers of the heart wall: epicardium, myocardium, and endocardium. The myocardium, however, may be greatly attenuated, as in this example, where only a single myocyte (black arrows) is pre...

TYPES OF ANEURYSMS Figure 28-1 TYPES OF ANEURYSMS True aneurysms involve all three layers of the vessel wall (intima, media, and adventitia). False aneurysms involve the intima and media and are “contained” from rupture by the adventitia layer. The wall typically consists of adventitia and neoint...

SHAPES OF ANEURYSMS Figure 28-2 SHAPES OF ANEURYSMS Aneurysms may be fusiform, with circumferential involvement of the vessel wall, or saccular, with focal outpouching of the vessel wall. Saccular aneurysms are further divided into those with wide and narrow necks. Wide neck aneurysms are usually...
