To break down the terms:

1. Biventricular - both ventricles (lower chambers) of the heart which actively pump blood throughout the circulatory system

2. Hypertrophy - increase in cell size; the cardiomyocytes become larger than normal

3. Dilation - increase in the lumen size; the ventricles become 'stretched out' like a balloon

Therefore, biventricular hypertrophy and dilation is where both ventricles of the heart become larger and have larger cells creating the walls. This is usually associated with severe congestive Heart disease in humans.
