The purpose of this study is to evaluate the safety and the effectiveness of the device Nit-Occlud® PDA-R in the percutaneous closure of patent ductus.
During the years 2003 to 2008, Kardiozentrum evaluated 1136 patients with echocardiographic studies, 14.7% of the patients were diagnosed with patent ductus arterious (PDA). The device "Nit- occlud® PDA-R" is a medical implant, developed for closure of patent ductus arterious (PDA) or ductus, which is an abnormal communication between the aorta and pulmonary artery. Untreated it can rise the intrapulmonary pressure and lead to serious complications like cardiac insufficiency.
The incidence of ductus as an isolated heart disease is between 3,6 and 7% of all the congenital heart diseases at sea level, and 10 - 14% in the altitude; rising up to 20% in cities at more than 2.500 m about sea level. The ductus' in high altitude are generally wider and larger than at sea level.
The device performs the function of generating the defect occlusion by the body itself. The implant stimulates the body to generate an epithelium over the implant so that the ductus closes. The Nit Occlud® PDA-R system is placed inside of the great arteries with a technique called minimally invasive cardiac catheterization. The implementation of the Nit-occlud® PDA-R system is developed for closure of patent ductus with 2 to 8 mm minimal diameter.

Cardiac manifestation of systemic rheumatological conditions, such as RHEUMATIC FEVER. Rheumatic heart disease can involve any part the heart, most often the HEART VALVES and the ENDOCARDIUM.
Occlusion of the outflow tract in either the LEFT VENTRICLE or the RIGHT VENTRICLE of the heart. This may result from CONGENITAL HEART DEFECTS, predisposing heart diseases, complications of surgery, or HEART NEOPLASMS.
A congenital coronary vessel anomaly in which the left main CORONARY ARTERY originates from the PULMONARY ARTERY instead of from AORTA. The congenital heart defect typically results in coronary artery FISTULA; LEFT-SIDED HEART FAILURE and MITRAL VALVE INSUFFICIENCY during the first months of life.
Disease-related laceration or tearing of tissues of the heart, including the free-wall MYOCARDIUM; HEART SEPTUM; PAPILLARY MUSCLES; CHORDAE TENDINEAE; and any of the HEART VALVES. Pathological rupture usually results from myocardial infarction (HEART RUPTURE, POST-INFARCTION).
Inflammation of the ENDOCARDIUM caused by BACTERIA that entered the bloodstream. The strains of bacteria vary with predisposing factors, such as CONGENITAL HEART DEFECTS; HEART VALVE DISEASES; HEART VALVE PROSTHESIS IMPLANTATION; or intravenous drug use.
