The goal of this observational study is to learn about the safety and effectiveness of pulmonary artery banding(PAB) therapy in pediatric heart failure(PHF) patients. The main questions it aims to answer are: * Can PAB therapy improve left ventricular(LV) function in PHF patients especially refractory PHF. * Can the complications caused by the PAB therapy be clinically acceptable? Participants underwent PAB therapy will be required to underwent echocardiography, electrocardiograms, complete blood counts, biochemical tests, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) follow-up before the initiation of PAB and at 1 month, 3 months, and 6 months after PAB surgery. Researchers will compare the LV function 6 months after PAB suergey and the preoperative ones to see if there is improvement.

25
Patient in this group will undergo pulmonary artery banding surgery for congenital heart disease.

RECRUITINGthe recurrence rate of heart failure
During follow-up visits, echocardiographic examination is conducted to measure the left ventricular function. If LVEF falls under 55%, it is recorded as a recurrence.
Time frame: after 6 months of PAB surgery
NT-proBNP level
The trend in NT-proBNP levels.
Time frame: after 6 months of PAB surgery
Incidence rate of drug adverse reactions
The incidence of abnormalities in complete blood count, electrolytes, liver and kidney function, and cardiac enzymes.
Time frame: after 6 months of PAB surgery
Readmission rate for heart failure
During follow-up visits, readmission for heart failure will be recorded.
Time frame: after 6 months of PAB surgery
