Key result
Trabeculae carneae were significantly stiffer (secant modulus 80.06 vs 55.14 KPa) and had higher collagen content (16.10% vs 10.06%) than the myocardium in the left ventricle.

Trabecular-myocardial differences may refine LV compliance estimates in models; leaves open human validation for computational applications.
Absolute Event Rate: 80.06% vs 55.14%
Trabeculae carneae are significantly stiffer and have higher collagen content than the myocardium, which is important for understanding left ventricular compliance and building accurate computational models.
Fatemifar et al. (2018) studied this question. Trabeculae carneae vs. Myocardium was evaluated on Secant modulus SM2. Trabeculae carneae were significantly stiffer (secant modulus 80.06 vs 55.14 KPa) and had higher collagen content (16.10% vs 10.06%) than the myocardium in the left ventricle.
