Abstract

Background:

B lines in lung ultrasound are useful to diagnose heart failure in adults. This study was to done to correlate lung ultrasound score with heart failure severity in CHD.

Material and methods:

Fifty infants with left to right shunt underwent Ross scoring, measurement of NT pro BNP and lung ultrasound. Lung was divided into 14 zones (7 on each side); each zone was scored as: No B lines = 0, less than 3 B lines = 1, 3-7 B lines = 2, > 7 /or confluent B lines = 3. Total score was calculated by adding all scores. A modified ultrasound score was calculated by excluding scores of 1. Relationship between ultrasound scores and heart failure was assessed. Receiver operator curve (ROC) was generated to find a cut-off of ultrasound score to detect moderate or severe heart failure.

Results:

No correlation was found between either total or modified lung ultrasound score with the modified Ross score or NT pro BNP. A cut-off of total lung ultrasound score of 11 gave an accuracy of 68% with area under the curve (AUC) of 0.64 to detect moderate or severe heart failure.

Conclusion:

Utility of lung ultrasound in detecting severity of heart failure in infants with left to right shunts is limited at present due to its low accuracy and lack of standardised method of scoring.
