Question

In pediatric patients, if the carotid/femoral pulse is palpable but there is no radial/pedal pulse or systolic blood pressure (SBP) is less than 90, What is the most likely diagnosis?

1) Coarctation of the aorta
2) Tetralogy of Fallot
3) Patent ductus arteriosus
4) Atrial septal defect

Answer 1

The most likely diagnosis is Coarctation of the aorta. It is a congenital abnormal narrowing of the aorta that restricts blood flow through the primary systemic artery. Symptoms may vary depending on the severity of the condition. The correct answer is option 1.

Step-by-step explanation:

If in pediatric patients the carotid/femoral pulse is palpable but there is no radial/pedal pulse or systolic blood pressure (SBP) is less than 90, the most likely diagnosis is Coarctation of the aorta.

Coarctation of the aorta is a congenital abnormal narrowing of the aorta that restricts blood flow through the primary systemic artery. This condition can be life-threatening and may present with symptoms such as difficulty breathing, poor appetite, trouble feeding, or failure to thrive in infants, and dizziness, fainting, shortness of breath, chest pain, fatigue, headache, and nosebleeds in older individuals.
