  abstract  = {After examining suitable parameters for a newly designed system, dynamic SIPGP could be developed. For the first time, SIPGP was performed while applying a constant flow of monomer solution through the reaction system. This added a new parameter: the flow rate (rfl). Accordingly, this parameter was examined, comparing dynamic to static SIPGP. It could be shown, that by applying higher rfl to the system, the contact angle increases, which indicates a slower coating. The flow patterns inside the reactor were then modelled and calculated. These calculations indicated, that, due to higher flow velocities, the contact angle on the coated samples would be lower on the sides of the sample and higher in the middle. This finding was verified by contact angle measurements. The influence of dynamic SIPGP on the temperature inside the reaction chamber during the reaction was examined by temperature sensors inside the reactor. This showed, that the constant flow of monomer solution can be utilized to decrease the warming of the reaction solution during the reaction. Finally it was shown, that dynamic SIPGP can decrease the formation of bulk polymer on the sample, which is forming during the reaction. This enables SIPGP to fabricate more homogeneous coatings by applying a constant monomer flow.},

  abstract  = {Background: Mitral regurgitation in ischemic heart disease (IMR) is a strong predictor of outcome but until now, pathophysiology is not sufficiently understood and treatment is not satisfying. We aimed to systematically evaluate structural and functional mitral valve leaflet and annular characteristics in patients with IMR to determine the differences in geometric and dynamic changes of the MV between significant and mild IMR. Methods: Thirty-seven patients with IMR (18 mild (m)MR, 19 significant (moderate+severe) (s)MR) and 33 controls underwent TEE. 3D volumes were analyzed using 3D feature-tracking software. Results: All IMR patients showed a loss of mitral annular motility and non-planarity, whereas mitral annulus dilation and leaflet enlargement occurred in sMR only. Active-posterior-leaflet-area decreased in early systole in all three groups accompanied by an increase in active-anterior-leaflet-area in early systole in controls and mMR but only in late systole in sMR. Conclusions: In addition to a significant enlargement and loss in motility of the MV annulus, patients with significant IMR showed a spatio-temporal alteration of the mitral valve coaptation line due to a delayed increase in active-anterior-leaflet-area. This abnormality is likely to contribute to IMR severity and is worth the evaluation of becoming a parameter for clinical decision-making. Further, addressing the leaflets aiming to increase the active leaflet-area is a promising therapeutic approach for significant IMR. Additional studies with a larger sample size and post-operative assessment are warranted to further validate our findings and help understand the dynamics of the mitral valve.},
