Abstract: OBJECTIVE: To explore changes in the plasma atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in patients with left-to-right shunt congenital heart disease (CHD) before and in the early stage after interventional occlusion and to evaluate the clinical significance. METHODS: Among 97 patients with left-to-right shunt CHD undergoing interventional occlusion, 34 cases had a VSD (ventricular septal defect), 35 cases had an ASD (atrial septal defect), and 28 cases had PDA (patent ductus arteriosus). Another 20 normal adults formed the control group. An ELISA was used to determine the plasma ANP and BNP levels before and on the third day after the operation to evaluate their correlations with cardiac functions and the defect size. RESULTS: The plasma ANP and BNP levels of patients with left-to-right shunt CHD were increased compared with those of the normal control group (P< 0.01), and the plasma ANP and BNP levels were decreased on the third day after interventional occlusion compared with the preoperative levels (P< 0.05). The plasma ANP and BNP levels were correlated with the New York Heart Association (NYHA) grade, left ventricular ejection fraction and defect diameter (P< 0.05). CONCLUSION: Patients with left-to-right congenital heart disease exhibit activation of ANP and BNP, which can be alleviated in the early stage after intervention occlusion. Left-to-right shunt congenital heart disease is given priority over atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). Early traditional methods included repair or correction by open heart surgery under extracorporeal circulation (also known as cardiopulmonary bypass, CPB). However, interventional therapy has become a developing trend for the treatment of congenital heart disease since 1967, when Porstmann et al. [1]. reported the transcatheter closure of ASD for the first time. The application of the AMPLATZER occluder, which is a simple and feasible method, has improved the safety of the treatment and enabled the therapeutic effect to reach ideal levels. The natriuretic peptide (NP) family consists of the atrial natriuretic polypeptide (ANP), the brain natriuretic peptide, which is also known as the B type natriuretic peptide (BNP), the C type natriuretic peptide (CNP), the renal natriuretic peptide (RNP) and the D type natriuretic peptide (DNP). These family members are similar in structure, have strong natriuretic, diuretic and vasodilative effects and antagonize the activity of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nerve. Together, the natriuretic peptides sensitively and specifically reflect the ventricular function state. Although all types of congenital heart disease differ in anatomical structure, they all contain the common features of heart failure. This study detected changes in the serum ANP and BNP levels in patients with left-to-right shunt congenital heart disease before and on the third day after interventional occlusion to evaluate the early changes in left-to-right shunt congenital heart disease after interventional occlusion through neuroendocrine.
