What does a pear-shaped heart see?

Pyriform heart refers to pear centroid, pear centroid is generally seen in atrial septal defect, rheumatic heart disease mitral stenosis, pulmonary heart disease and other diseases.

1. atrial septal defect

patients due to hemodynamic changes, so that atrial pressure is too high, resulting in ventricular hypertrophy, showing pear centroid.

2. rheumatic heart disease mitral stenosis

patients due to the channel can not be fully opened, resulting in left atrial blood can not flow into the left ventricle, resulting in left atrial dilation, so that pressure changes, causing the above phenomenon.

3. pulmonary heart disease

If the patient has pulmonary heart disease, resulting in cardiac blood flow affected, so that cardiac structure changes, resulting in pear centroid.
