PY - 2017 T2 - Hurst's The Heart, 14e AB - Cardiac trabecular anatomy is characterized by extreme individual and population variability that corresponds to a sort of individual cardioprinting. In normal hearts, trabeculae undergo continuous and quantifiable geometric changes during the cardiac cycle; they actively provide mechanical leverage during early systolic ejection through contraction, and relaxation occurs during late diastole at larger ventricular volumes.1 In the left ventricle, trabeculae can be minimally represented or may be so numerous and prominent that they confer a “spongy” appearance to the endocardial surface of the ventricles. The latter corresponds to the term left ventricular noncompaction (LVNC).
