Boot-shaped heart is a condition in which the heart is enlarged, especially the left ventricle enlarges to the lower left side, and the waist of the heart changes from an obtuse angle to an approximate right angle of about 90 degrees, giving the heart an overall shape like a boot, and is referred to as a boot-shaped heart. Boot-shaped heart is commonly associated with aortic regurgitation and aortic stenosis, which is often referred to as aortic heart. In addition, it can also be seen in hypertensive heart disease, tetralogy of Fallot, etc. Once the boot-shaped heart is detected by X-ray, combined with the patient’s symptoms, it is necessary to go to the hospital immediately for a cardiac ultrasound examination. The primary cause of the heart disease will be determined by the ultrasound examination and aggressive treatment will be given.
