ventricular
Of heart cavities
Ventricular means relating to a ventricle—a chamber or cavity in an organ.
Most commonly it refers to the heart's lower chambers: ventricular fibrillation, left ventricular hypertrophy.
It also applies to the fluid-filled cavities in the brain: ventricular enlargement.
The word appears almost exclusively in medical contexts.
