What are the clinical significance of pear-shaped heart and boot-shaped heart in health assessment review questions? Solve! ! !

Hello, pear-shaped heart usually occurs in patients with mitral stenosis. Mitral valve stenosis will lead to the diastolic blood of cardiac cycle can not smoothly enter the left ventricle from the left atrium, and blood will accumulate in the left atrium, which will lead to the increase of left atrial pressure, compensatory hypertrophy, disappearance of heart and waist depressions, and make the whole heart pear-shaped.

Boot-shaped heart means that the waist changes from an obtuse angle to a right angle, and the heart looks like a boot. This is because the left ventricle expands and protrudes (the toe of the boot), and the right ventricle also expands (the left heart and waist are pulled to the right, resulting in the depression of the heart and waist), and the combination of the two appears. It is more common in aortic insufficiency. Occasionally, aortic stenosis can also be seen.
