Most often a bump on a testicle is a cyst, called a varicocoele, which is harmless. However it could be more serious and its important to have a doctor check it out.
According to the Mayo Clinic, testicle pain could be a result of a hernia, kidney stones, injury, blood vessel inflammation, urinary tract infection, or a variety of other causes. http://www.mayoclinic.com/health/testicle-pain/MY00464/DSECTION=causes
Testicle pain could be something as simple as a bruise, or it could be something potentially dangerous like a torsioned testicle that occurs when the testicle wraps and tangles the various ducts and vessels it is connected to inside the sac.
As long as blood is pumping through the testicle then it should have a pulse, the left testicle should have a pulse too.
Any bump or knot on the testicle need to be looked at by a doctor. Could be nothing, could be cancer. Go to the doctor, ASAP.

This could result in a learning defect.Also, the anesthesia during open heart surgery on an infant could affect brain development. But this would be in all cases, not just HLHS
An infant could answer this question.
This could result from an injury, a wound, testicular cancer, or voluntary surgery.
