In brief: Left ventricle
It is usually the left ventricle that enlarges (hypertrophies) in athletes.
This is the main pumping chamber of the heart. Other areas can enlarge depending on the condition causing it. If concerned, get it checked out. You may need an EKG and an echocardiogram (ultrasound of the heart).
