The goal of this observational study is to compare the safety and effectiveness of a modified drug therapy with traditional drug therapy in pediatric heart failure patients. The main questions it aims to answer are: * Can a modified drug therapy improve left ventricular function in pediatric heart failure patients? * Can the adverse drug reactions caused by the modified drug therapy be non-inferior (clinically acceptable) to those of the traditional drug therapy? Participants will be assigned to either the Modified Drug Therapy Group (comprising angiotensin-converting enzyme inhibitor (ACE-I), beta-blockers, diuretics, potassium supplements, and spironolactone) or the Traditional Drug Therapy Group (diuretics and potassium supplements) based on personal preferences and clinical assessments by their attending physicians. They will undergo a 6-months course of medication. Additionally, echocardiography, electrocardiograms, complete blood counts, biochemical tests, and measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) were conducted before the initiation of medication therapy and at 1 month, 3 months, and 6 months after treatment commencement. Researchers will compare the Modified Drug Therapy Group and the Traditional Drug Therapy Group to see if the recurrence rate of moderate to severe mitral valve regurgitation, as assessed by echocardiography after 6 months of treatment, is lower in the former than in the latter.

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 treatment
NT-proBNP level
The trend in NT-proBNP levels.
Time frame: after 6 months of treatment
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 treatment
Readmission rate for heart failure
During follow-up visits, readmission for heart failure will be recorded.
Time frame: after 6 months of treatment
