<qa>  What is the morphological epiphenomenon common to many distinct myocardialThis project will expand on research conducted by the investigators group, where the investigators have demonstrated increased LV trabeculation, satisfying currently existing criteria for LV Non-Compaction Cardiomyopathy LVNC, in groups exposed to high cardiac workloads. To the investigators knowledge, this will be the first prospective study aiming to demonstrate a direct relationship between high levels of exercise and increased LV trabeculation. This study may add weight to the theory that this entity currently described as LVNC, is a morphological epiphenomenon common to many distinct myocardial remodeling processes associated with increased cardiac preload and afterload and may better define normal adaptive increases in LV trabeculation.
