athlete's heart,

common term for an enlarged heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

 associated with repeated strenuous exercise. As a result of the increased workload required of it, the heart will increase physiologically by enlarging chambers and muscle mass, or hypertrophy by enlarging the size of the chambers and increasing the volume of blood pumped per stroke. Consequently, the heart has to contract less frequently and at rest will beat as few as 40 times per minute as compared with an average number of 70 beats in a normal heart. The condition is not pathological, and there is generally no danger of cardiac disability arising from it.

It is reasonable to think that usual application of the 3D with a periodical assessment of the morphology and of the function of the RV chamber in young and regularly trained athletes, can allow to find the initial and peculiar modifications of the athlete's heart, offering the possibility to obtain a better and more adequate follow -up in case of uncertain diagnosis.
