Time period after transcatheter PDA closure with changes in left ventricular function and nutritional status

Background Few studies perform follow ups on patent ductus arteriosus (PDA) patients who undergo transcatheter closure. In addition to side effects from the procedure, it is important evaluate changes in left ventricular function (LVF) parameters and nutritional status.
 Objective To compare LVF status before during one-year period post-transcatheter PDA closure, potential associated factors post-closure patients.
 Methods This retrospective cohort study was done a single center diagnosed with had undergone Data were obtained subjects’ medical records. The relationship between time span [ejection fraction (EF) fractional shortening (FS)] analyzed by Friedman repeated ANOVA tests; test. periods 1, 3, 6, 12 months post-closure. Factors potentially linear regression.
 Results A total of 30 closure included. body weight mean at 13.1 kg. We found significant after status, comparison pre-closure post-closure, EF (66.6 vs. 70.9%, respectively; P<0.001) FS (34.4 37.8%, significantly higher. addition, more normal than Age not related (EF: r=0.212; P=0.260; FS: r=0.137; P=0.471).
 Conclusion Both improve gradually over compared pre-closure. size improved status.
