Patient's Query

Hi doctor,

My baby's heart rate is 110 beats per minute. During the examination, the echocardiogram shows S1 normal, S2 split 3/6, and continuous murmur at the left infraclavicular region. What does the information indicate? Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I have seen the reports of the echocardiogram (attachment removed to protect patient identity). The patient has a condition called patent ductus arteriosus. Usually, the ductus arteriosus closes at the birth of a baby, but sometimes, it remains patent and does not close naturally. This condition is called patent ductus arteriosus.

Labored breathing and poor weight gain are the earliest signs of PDA. An uncorrected PDA may lead to congestive heart failure with increasing age. PDAs can be closed by percutaneous interventional method (avoiding open heart surgery). A platinum coil can be deployed through a catheter through the femoral vein or femoral artery, which induces thrombosis (coil embolization).

Alternatively, a PDA occluder device composed of nitinol mesh is deployed from the pulmonary artery through the PDA. The echo of the baby shows a left-to-right shunt. It is a good time to do the surgery, as after a particular time due to right ventricle hypertrophy, the shunt reverses itself, which is called reversal of shunt, and complicates the prognosis.

If left untreated, the disease may progress from left-to-right shunt (acyanotic heart) to right-to-left shunt (cyanotic heart) called Eisenmenger's syndrome. Pulmonary hypertension is a potential long-term outcome that may require a heart or lung transplant. Another complication of PDA is intraventricular hemorrhage.

I hope that you get your answer.

Please let me know if you want some help.

Thank you.
