I think that the information that was given to you was misinterpreted. There is no pulmonary gland. There is a pulmonary artery, which is the artery that takes blood from the right side of the heart to the lungs to get oxygen. The fact that it is gone suggests that this was an innocent, or normal, murmur; 2/3 of all kids have innocent murmurs that are not associated with any actual heart disease, As well, this is not typically associated with the function of the immune system or with asthma, although without evaluating your grandson, I cannot say for sure what is going on. I recommend that you either discuss this further with your child or accompany them for the next doctor's visit.
