Non compaction is diagnosed when the trabeculations are more than twice the thickness of the underlying ventricular wall.

The left ventricular wall is three times the thickness of the right.

An old myocardial infarction, months or even years old, had already destroyed part of the left ventricular wall.

In addition, the ventricular walls maintain the same thickness, characteristic of pathophysiological cardiac dilation.

They usually arise from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood.

Larkin, a 17-year-old senior, was found to have a congenital heart condition, a thickening of the left ventricular wall that affects blood flow.

No surprise, because the ventricular walls don't line up, either.

It is also involved in the development of the ventricular wall and the connection of the outflow tract to the great vessels.

Surgeons typically assemble their own tools to core and remove a plug of muscle from the left ventricular wall.

It is most commonly located in the interventricular septum or left ventricular wall.
