In restrictive cardiomyopathy (RCM), echocardiography typically demonstrates non-dilated ventricles accompanied by marked enlargement of both _____.
Answer
atria
Explanation
The echocardiographic description notes **markedly enlarged atria**, approximately two to three times larger than the ventricles, with small-to-normal-sized ventricles and abnormal filling characteristics. This contrasts with the prominent atrial enlargement and relatively small ventricular chambers characteristic of the restrictive pattern. **Key takeaway:** Disproportionate atrial enlargement is an important echo clue in RCM.\n\n**Glossary:** **Atrium**: One of the heart's upper receiving chambers. **Echocardiography**: Ultrasound imaging of the heart.
