Infant with Aortic Stenosis Being Examined by Nursing Professional

In the world of paediatric healthcare, one of the significant challenges faced by nurses is assessing infants with aortic stenosis. This condition, characterised by the narrowing of the aortic valve, can have serious implications for an infant's health.

The primary cause of aortic stenosis in infants is often a congenital malformation of the aortic valve, most commonly a bicuspid or unicuspid valve. This is the result of fusion of valve leaflets during fetal development. It's worth noting that this condition predominantly affects males at a ratio of about 3:1.

During the assessment of infants with aortic stenosis, nurses should prioritise gentle handling to avoid complications, careful cardiovascular examination, close monitoring of respiratory status, and vigilant assessment of vital signs such as heart rate, blood pressure, and oxygen saturation levels.

Gentle handling is crucial, especially if the infant is fragile due to associated systemic effects or treatments. Careful cardiovascular examination involves noting signs of left ventricular outflow obstruction, such as a harsh systolic murmur heard best at the upper right sternal border, weak or delayed peripheral pulses, and signs of poor perfusion or heart failure (tachypnea, feeding difficulties, diaphoresis).

Nurses should also closely monitor the infant's respiratory status, as infants with cardiac defects often present with respiratory distress or may develop heart failure. Recognition of symptoms like irritability, poor feeding, or failure to thrive, which may reflect poor cardiac function, is also essential.

Awareness of the possible need for urgent interventions and close collaboration with pediatric cardiologists for diagnostic echocardiography and management planning is crucial. Gathering a detailed medical history is also crucial, including questions about the infant's prenatal care, birth history, family history of heart conditions, and any signs or symptoms the infant may be experiencing.

Certain genetic conditions, such as Williams syndrome or Turner syndrome, can increase the risk of developing aortic stenosis. Maternal infections during pregnancy, such as rubella, can also increase the likelihood of a baby developing aortic stenosis.

In summary, the nursing assessment for an infant with aortic stenosis must focus on gentle care, thorough cardiovascular and respiratory evaluation, and early identification of compromised cardiac output or evolving heart failure. The information gathered from the nursing assessment serves as a foundation for the healthcare team to develop an appropriate treatment plan for the infant, ensuring the best possible outcomes.
