Pear-shaped heart, also called boot-shaped heart, is a heart disease that causes a change in the shape of the heart, which can be clearly seen in x-rays and body fluoroscopy as a pear-shaped change in the shape of the heart. There are many conditions that cause a pear-shaped heart, such as heart valve disease, dilated cardiomyopathy, and complex congenital heart disease, such as tetralogy of Fallot. If you develop a pear-shaped heart, you need to go to the hospital for an examination. Ultrasound of the heart can clearly show the changes in the internal structure of the heart, and can be used to determine the cause of the pear-shaped heart and treat it actively.
