Final answer:
Coarctation of the aorta presents in infants with symptoms affecting feeding and breathing, while older individuals may have cardiovascular symptoms. Treatment options include surgery or angioplasty.
Step-by-step explanation:
Coarctation of the aorta typically presents in different ways depending on age. In infants, it may present with symptoms such as difficulty breathing, poor appetite, trouble feeding, or failure to thrive. This is due to the severity of the narrowing restricting blood flow. In older individuals, it may go undetected until later in life, with symptoms including dizziness, fainting, shortness of breath, chest pain, fatigue, headache, and nosebleeds. Treatment may involve surgery or angioplasty, with a higher chance of survival if surgery is performed earlier.
