Demonstrates that an eccentric mitral regurgitation jet can cause disproportionate enlargement of the left atrial appendage without significant dilatation of the main left atrial chamber.

Alerts echocardiographers to eccentric MR as cause of isolated giant LAA; leaves open need for systematic study of jet-directed remodeling.
Dilatation primarily confined to the left atrial appendage (LAA) is an unusual condition in nonrheumatic mitral valve disease. We report a case of 56-year-old male with a giant LAA secondary to ischemic severe mitral regurgitation without significant dilatation of the left atrial main chamber. The mitral regurgitation jet was directed toward the LAA, which we thought as the cause of disproportionate LAA enlargement.
