A heart murmur was heard in a 5-month-old female infant during a postnatal physical examination, and echocardiography showed pulmonary valve stenosis with a pressure gradient of 51 mm Hg and bilateral ventricular wall hypertrophy. This case involved an infant with isolated pulmonary valve stenosis and a history of subarachnoid hemorrhage after birth. She was scheduled to undergo balloon pulmonary valvuloplasty under general anesthesia. Interventional balloon pulmonary valvuloplasty will lead to a transient reduction in pulmonary blood flow, end-tidal carbon dioxide, and blood oxygen saturation. Bradycardia may even happen, which requires vasoactive agents to treat if it is necessary.

摘要

A heart murmur was heard in a 5-month-old female infant during a postnatal physical examination, and echocardiography showed pulmonary valve stenosis with a pressure gradient of 51 mm Hg and bilateral ventricular wall hypertrophy. This case involved an infant with isolated pulmonary valve stenosis and a history of subarachnoid hemorrhage after birth. She was scheduled to undergo balloon pulmonary valvuloplasty under general anesthesia. Interventional balloon pulmonary valvuloplasty will lead to a transient reduction in pulmonary blood flow, end-tidal carbon dioxide, and blood oxygen saturation. Bradycardia may even happen, which requires vasoactive agents to treat if it is necessary.
