Heart 1. (A) Organizing fibrin thrombus unites anterior aspect of commissure between right coronary cusp (RCC; left) and noncoronary cusp (NCC; right). (B) Aortic aspect of the aortic valve shown in (A) showing the fusing commissure between RCC (left) and NCC (right). A portion of the left ventricular assist device outflow anastomosis in the aorta distal to the aortic valve is present (top). (C) Organizing intercuspal fibrin-platelet thrombus (left) and portion of RCC (right); artifactual disruption has occurred during sectioning. (Hematoxylin and eosin; ×70.)

Heart 3. (A) Fibrous fusion of commissure between left coronary cusp and noncoronary cusp (next to forceps). The fusion between the right coronary and left coronary cusps was disrupted before photography. (B) Histologic section of fused portion of left coronary and noncoronary cusps. The original valve cusps appear dark red, and the intervening area of fusion appears paler and represents less dense, more recently formed collagen, probably due to organization of an intercuspal fibrin deposit. (Elastic van Gieson stain; ×20.)

(A) Healed, fibrous commissural fusion of two aortic valve cusps in an additional patient not discussed in the article, whose LVAD had been implanted for 165 days (see Addendum). (B) Transverse section of fused commissure. (Elastic van Gieson stain; ×20.)
