Interventional treatment of common congenital heart diseases: the common view of Chinese medical experts. Part Three; interventional treatment of patent ductus arteriosus

Patent ductus arteriosus (PDA) represents 10%-20% of all congenital heart diseases. Percutaneous transcatheter device closure of PDA has been an effective alternative to surgical treatment and has been increasingly becoming the treatment of choice for most PDAs in children and adults. The indication for percutaneous closure of PDA has been further expanded with the development of domestic devices in China and almost all the patients with PDA can be cured by this therapy. This chapter will systematically describe the indications, contraindications for percutaneous PDA occlusion, how to close PDAs by using coils and umbrella devices, procedural complications and preventions. How to treat infant PDA, PDA with severe pulmonary arterial hypertension as well as the post-surgery residual shunt will be also discussed in detail in this chapter. (authors)
