In valve disease, many variations of repair/replacement techniques have been used with varying success rates in terms of perioperative mortality, preservation of postoperative ventricular function or long-term morbidity. More recently, percutaneous methods for replacement of the pulmonary , aortic valve
or tricuspid valve or clips of the mitral valve have been successfully introduced. These catheter based techniques were also pioneered by our institutions. There is consensus, that different types of valve prosthesis (size, shape) or repair techniques will have different functional results. The planned DSS will allow for in-silico simulation of different treatment options and thus allow comparing their immediate hemodynamic outcome.
