Abstract: 　Structural heart diseases refer to anatomic heart or great vessels abnormalities by congential or acquired factors, including congenital heart disease, acquired heart valve disease, cardiomyopathy. In recent years, interventional therapy in structural heart diseases has gradually matured and been widely applied in clinical practice. Due to the fragility of heart valves and valve related organizations, or the congenital dysplasia of valves, the complex interventional therapeutic procedures can cause valve-related complications. In this paper, the causes, prevention and treatment of valve-related complications induced by interventional therapy in structural heart diseases are introduced.
