Files in this Data Supplement:

• Movie I - (AVI (573 KB) Movie loop of the apical 4-chamber view on transthoracic echocardiography, showing ill-defined wall motion abnormality of the distal lateral wall at the LV apex. Window media player or Quicktime
• Movie II - (AVI) (965 KB) Movie loop of the left ventricular (LV) angiogram showing an unusual outpouching of the LV, close to the apex, with a trabeculated appearance. Window media player or Quicktime
• Movie III - (AVI) (589 KB) Movie loop of the apical 4-chamber view on transthoracic echocardiography after intravenous injection of echocontrast (Definity™), showing opacification and delineation of the distal lateral wall. This region is thinned and mildly dyskinetic, with prominent trabeculations and deep intertrabecular recesses consistent with non-compaction. Window media player or Quicktime
• Movie IV - (AVI) (808 KB) Movie loop of magnetic resonance imaging in the apical 4-chamber view demonstrating regional thinning and dyskinesis, with prominent trabeculations and deep intertrabecular recesses of the distal lateral wall, confirming the diagnosis of isolated focal LV non-compaction.
