[Infective prosthetic endocarditis following percutaneous edge-to-edge mitral valve repair - A Case-report of a successfully medically-treated Staphylococcus epidermidis endocarditis and a literature review]. / Endocardite infectieuse sur prothèse après implantation de Mitra-Clip ­ Cas d'un succès du traitement médical sur une endocardite à Staphylococcus epidermidis et revue de littérature.

During the last decade there has been a craze for the percutaneous edge-to-edge mitral valve repair technique with the Mitra-Clip device. This is an alternative treatment to mitral valve surgery for severe mitral regurgitation. In France, this device is aimed at poor candidates for mitral valve surgery. It involves intra-cardiac prosthetic material, which exposes them to the risk of bacterial endocarditis. The consequences of this infective disease can be dramatic, especially for these old patients who suffer from multiple comorbidities. It appears to be a rare but relatively unknown and potentially underestimated complication. The relative data remain scarce and consist of rare case-reports. We report an original case of a Methicilline-sensitive Staphylococcus epidermidis mitral endocarditis following the implantation of clips two months earlier. The patient was then successfully treated with antibiotics. Since the first Mitra-Clip implantation in 2003, only 19 cases of endocarditis have previously been reported. This article proposes a review of theses case-reports and a collection of their relevant clinical, echocardiographic and microbiological characteristics, the delivered therapies and their outcomes. These data contribute to a humble discussion around the main stakes of the disease, which are the prevention, the diagnosis, the involved bacteria's type, the prognosis and the treatments with a focus on the question of the recourse to surgical management.
