Infos

The book describes first all practical steps necessary in a clinic from the idea of the introduction of the minimally-invasive mitral valve surgery up to practical realization of the operation program. An extensive and detailed representation of the reconstruction technologies possible today as well as the specific features of the endoscopic application allow quick learning of the surgical technology. Informative pictures as well as videosequences of the most frequent findings and the accompanying reconstruction technologies underline the practical orientation of the book.
