Criss-cross heart is a congenital heart defect in which the two main arteries of the heart, the aorta and the pulmonary artery, are switched. This defect is caused by abnormal development of the heart during fetal development. It is believed to be caused by genetic factors, environmental factors, or a combination of both.

The treatment for criss-cross heart depends on the underlying cause. Treatment may include medications, lifestyle changes, and/or surgery.

Medications: Medications may be prescribed to help reduce symptoms and improve heart function. These may include beta-blockers, ACE inhibitors, diuretics, and calcium channel blockers.

Lifestyle changes: Making lifestyle changes such as quitting smoking, exercising regularly, and eating a healthy diet can help improve heart function and reduce symptoms.

Surgery: In some cases, surgery may be necessary to repair the heart defect. This may include open-heart surgery or a procedure called transcatheter aortic valve replacement (TAVR).

The risk factors for Criss-cross heart include:

1. Congenital heart defects
2. Family history of congenital heart defects
3. Premature birth
4. Low birth weight
5. Maternal diabetes
6. Maternal smoking
7. Maternal alcohol use
8. Maternal drug use
9. Maternal obesity
10. Maternal hypertension

At this time, there is no cure for criss-cross heart. However, medications can be used to manage the symptoms and reduce the risk of complications. These medications include beta-blockers, ACE inhibitors, diuretics, and anticoagulants. Additionally, lifestyle modifications such as quitting smoking, maintaining a healthy weight, and exercising regularly can help reduce the risk of complications.
