Right-situated hearts are rare, and the percentage of right-situated hearts in the population is about two in 10,000 people. A person with right-sided heart is one in whom the atria, ventricles, and blood vessels are positioned like a mirror image of the normal heart, and right-sided heart is a general term for a heart that has shifted its position in the chest cavity to the right side. Simple right-sided heart without other congenital anomalies of the heart does not cause obvious pathophysiologic changes or symptoms, and later on, like normal people, it may also suffer from acquired heart disease. However, dextrocardia is associated with more serious congenital cardiovascular malformations. The incidence rate of right heart is about two out of ten thousand, which can be found in the Chinese Physical Fitness Census, right heart accounts for about one half of the incidence rate of right heart, that is to say, the incidence rate of right heart is about 0.5 out of ten thousand.
