 This 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.
