Progress of cardial troponin and the injury after transcatheter closure of congenital heart disease

That thranscatheter therapy of congenital heart disease (CHD) can cause myocardial injury is one of the focal points of attention in disciplines. Cardiac troponin (cTn) with its high specificity and sensitivity becomes special myocardial injury measure indicators. The types of CHD, the sizes of defect and occluder, the degree of stenosis, and the patients age and body weight, with their influence due to the concentrations of cTn,can be tested as associated risk factors of the myocardial injury. Key words: Congenital heart diease;  Myocardial injury;  Cardiac troponin Ⅰ
