Abstract

TCA is not associated with increased LV mass but rather with smaller hearts that have greater relative longitudinal shortening of the left ventricle. This finding suggests that TCA could represent an adaptive response to longitudinal systolic distortion of coaxially oriented coronary arteries that dynamically produce shear stresses associated with expansive coronary remodeling.
