Advances in medical technology and cardiac treatments are ongoing. What can be reported today may have been updated within a year. As with any heart symptom, rapid attention is the key to recovery, both its rate and its effectiveness. Those who leave seeking medical attention are those who suffer the worse effects for the damage to the brain may be irreversible if left.

Sometimes drugs can be injected into the pericardial area of the heart to slow the tumor's growth. This is not always successful but hopefully advances in this treatment will occur in the not too distant future.
