Item type: Item , Bacterial nanocellulose as a new patch material for closure of ventricular septal defects in a pig model(Oxford University Press, 2014) Nora Lang; Elena Merkel; Franziska Fuchs; Dieter Schumann; Dieter Klemm; Friederike Krämer; Susanne Mayer‐Wagner; Christian Schroeder; Franz Freudenthal; Heinrich NetzBNC patches can close VSDs with good mid-term results and its biocompatibility can be considered as satisfactory. Its elasticity increases in the presence of blood, which might be advantageous. Therefore, it has potential to be used as an alternative patch material in congenital heart disease.Item type: Item , Chronic hypobaric hypoxia, patent arterial duct and a new interventional technique to close it(Cambridge University Press, 2011) Franz Freudenthal; Alexandra Heath; Jorge Villanueva; Janne Mendes; Ximena Vicente; Inge von Alvensleben; Gabriel Echazú; Joaquin Navarro; Nora Lang; Rainer Kozlik‐FeldmannWe conclude that the "Nit-Occlud® PDA-R" device is safe and effective in closing patent arterial duct up to a diameter of 8 millimetres.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.Item type: Item , Transcatheter closure of large patent ductus arteriosus at high altitude with a novel nitinol device(Wiley, 2011) Alexandra Heath; Nora Lang; Daniel S. Levi; Miguel Granja; Jorge Villanueva; Joaquin Navarro; Gabriel Echazú; Rainer Kozlik‐Feldmann; Pedro J. del Nido; Franz FreudenthalThe Nitocclud PDA-R device is safe and effective and can easily close very large PDAs. This device has a high rate of complete occlusion within 1 year and is easily retrieved if embolized.
