Interrupted aortic arch
Interrupted Aortic Arch
Interrupted aortic arch (IPA: /ɪnˈtɜːrʌptɪd ˈeɪɔːrtɪk ɑːrk/), often abbreviated as IAA, is a rare congenital heart defect in which the aorta is not completely developed, resulting in a gap or interruption in the aortic arch. The etymology of the term comes from the Latin interruptus, meaning "broken off", and the Greek aortē, referring to the main artery of the body.
Classification
Interrupted aortic arch is classified into three types based on the location of the interruption:
- Type A: The interruption occurs distal to the left subclavian artery.
- Type B: The interruption occurs between the left common carotid and left subclavian arteries.
- Type C: The interruption occurs between the innominate (brachiocephalic) and left common carotid arteries.
Symptoms and Diagnosis
Symptoms of interrupted aortic arch typically present shortly after birth and may include rapid breathing, poor feeding, and a weak pulse. Diagnosis is often made through echocardiography, a type of ultrasound used to create images of the heart.
Treatment
Treatment for interrupted aortic arch typically involves surgery to repair the aorta. This is often performed in stages, with the first surgery occurring shortly after birth.
Prognosis
With early diagnosis and treatment, the prognosis for individuals with interrupted aortic arch can be quite good. However, long-term follow-up care is typically required to monitor for potential complications.
