In primary HCM, the ventricular septum may be disproportionately involved compared with the left ventricular free wall.
Answer
true
Explanation
The slides state that the ventricular septum is most commonly **disproportionately involved** relative to the left ventricular free wall in primary HCM. This asymmetric pattern can distort the left ventricular cavity and may contribute to outflow obstruction. **Key takeaway:** Septal-predominant hypertrophy is a characteristic pattern, although other patterns can occur.\n\n**Glossary:** **Ventricular septum**: The wall separating the right and left ventricles. **Asymmetric**: Unequal in distribution.
