Final answer:
Rheumatic heart disease is assigned when a patient has inflammation and damage to the heart valves due to rheumatic fever.
Step-by-step explanation:
Rheumatic heart disease is assigned when a patient has inflammation and damage to the heart valves due to rheumatic fever. Rheumatic fever is an autoimmune response triggered by the presence of Streptococcus pyogenes bacteria, and it can lead to inflammation in multiple heart valves. So, if a patient has more than one type of heart valve disease in different heart valves, it is true that rheumatic heart disease may be assigned.
