| Outline of Final Research Achievements |
There are two aims of this study. First is to establish an experimental model of pulmonary vein obstruction (PVO) after repair of total anomalous pulmonary vein connection, and second is to examine possible preventive effect of rapamycin-eluting films for PVO. We could establish the PVO piglet model by cut and suture method..In this model, intimal hyperplasia occurred on the anastomotic site and it progressed toward lung parenchyma 8 weeks after the procedure. In addition, we established very thin drug-eluting film (the thickness was about 40 µm) which include rapamycin and polylactic-co-glycolic acid. Investigation of preventive effect of this film for PVO is in progress using the piglet PVO model.
