BIOL 2402: Human Anatomy and Physiology II Cardiac Case Study: Congenital Cardiac Defects
Case Study: A month- old female neonate is brought to the pediatrician for a respiratory infection. Upon evaluation, the pediatrician notes that the infant is presenting with the following symptoms: Heart murmur, mild cyanosis, poor weight gain, and difficulty feeding. The infant’s parents also note that the child sweats during feeding and seems exhausted by the activity. Antibiotics are prescribed to clear the respiratory infection and suspecting a ventricular septal defect (VSD), a referral to a neonatal cardiologist is made. The neonatal cardiologist confirms that the infant has a small-sized VSD and recommends to simply keep tabs on the child with regular check-ups. Instructions:
1) Work with your team in researching VSDs.
2) Follow your presentation guidelines posted on Canvas. Use it as a checklist to make sure you hit all the marks and earn high scores!
3) Additionally, incorporate answers to these questions into your presentation:
a. Explain why the child sweats while feeding and why he is exhausted by it. Why is the child having difficulty feeding when feeding should be effortless?
b. Based on your knowledge of the pulmonary circuit, explain why infants with VSDs are prone to respiratory infections.
c. Why did the neonatal cardiologist recommend watchful waiting with regular check-ups instead of surgery to seal the VSD?
