Item type: Item , Evaluation of a new hybrid technique for closure of muscular ventricular septal defects in a long-term setting(Elsevier BV, 2009) Rainer Kozlik‐Feldmann; Nora Lang; Anja Lehner; Matthias Sigler; Christoph Schmitz; Ralf Sodian; Franz Freudenthal; Robert Dalla‐Pozza; N. V. Vasilyev; Pedro J. del NidoItem type: Item , Evaluation of a self-centering patch system for closure of muscular ventricular septal defects in a pig model(Georg Thieme Verlag, 2010) Nora Lang; A Mever; Elisabeth Merkel; R Thalmann; Anja Lehner; Franz Freudenthal; Nikolay V. Vasilyev; Pedro J. del Nido; Heinrich Netz; Rainer Kozlik‐FeldmannObjective: Closure of muscular ventricular septal defects (mVSDs) beyond the moderator band is still challenging. Recently, we established a new hybrid technique for closure of mVSDs on the beating heart. Here, we evaluated a self-centering patch system for this technique.Item type: Item , Evaluation of bacterial cellulose as a new patch material for closure of muscular ventricular septal defects(Georg Thieme Verlag, 2010) Nora Lang; Matthias Sigler; Elisabeth Merkel; F. Fuchs; Dieter Schumann; Dieter Klemm; Frank Krämer; Andreas Meyer; R Thalmann; Anja LehnerObjective: Bacterial Cellulose (BC) is an innovative biomaterial with unique properties such as high mechanical strength, high water content and poor degradation in vivo. The fiber network structures show similarities to those of collagen. Recent studies have shown that the BC might have a potential to be used as a scaffold in tissue engineering. Thus, aim of this study was evaluation of the in vivo biocompatibility of BC in the heart and the applicabilities as a patch material for muscular ventricular septal defects (mVSD).Item type: Item , Patch Closure of Muscular Ventricular Septal Defects With a New Hybrid Therapy in a Pig Model(Elsevier BV, 2008) Rainer Kozlik‐Feldmann; Nora Lang; Regine Aumann; Anja Lehner; D Rassoulian; Ralf Sodian; Christoph Schmitz; Martin Hinterseer; Rabea Hinkel; Eckart TheinItem type: Item , Preclinical evaluation of a new self‐expanding device for closure of muscular ventricular septal defects in a pig model(Wiley, 2009) Nora Lang; Christoph Schmitz; Anja Lehner; Franziska Fuchs; Alexandra Heath; Franz Freudenthal; Bernd J. Wintersperger; Armin Huber; Eckart Thein; Heinrich NetzOur preclinical study shows successful closure of iatrogenic created mVSDs without residual shunting. The device is characterized by a more controlled deployment, an independent deployment of disk and waist, and a good alignment of the left ventricular disk to the muscular septum.
