title: [Desinsertions of aortic valve prostheses treated by subcoronary implantation of the valve].
abstract: Thirteen patients requiring emergency surgery for desinsertion of their aortic valve prostheses were treated by subcoronary aortic valve grafting, using a procedure based on Danielson's method. The particularity characterizing this technique consists in obtaining direct revascularization of the left coronary artery via a coronary sinus approach, thereby reducing the complexity of the surgical operation. All the patients presented valvular ring lesions, associated with aortic root degeneration accountable for failure of conventional artificial aortic valve replacements; in 8 patients, this had been their third aortic prosthetic surgery. The mean survival period for eight patients was 44 months. Considering the highly critical aspect of such lesions, this technique apparently constitutes a working solution, barring all chances for relapse.
