Objective: to study the clinical efficiency of introducing an algorithm for organ protective intensive care. Materials and methods. 3278 case histories of patients admitted to the clinic in 2000-2009 for surgical treatment (under extracorpore al circulation) for coronary heart disease (CHD) and acquired heart defects (AHD) were retrospectively analyzed. Throughout the analyzed period, the patients operated on for CHD and AHD were 2068 (63.1%) and 1210 (36.9%), respectively; the postoperative incidence of multiple organ dysfunction (MOD) among all the patients was 11.8% (378 patients); mortality in MOD was 3.75% (n=123) of the operated patients (included into the study) or 32.5% of all the patients with MOD. Conclusion. The incidence of MOD is in proportion to the number of surgical interventions and depends on their specific features (recurrence, baseline severity, comorbidity, or multifocal atherosclerosis). Preventive intensive therapy for MOD reduced mortality and altered its syndromic pattern towards a preponderance of pyoseptic complications.
Aim: to evaluate the manipulative properties of the system being developed for cardiac valve re-operation on an in vitro bovine heart model.Material and methods. The prototype of the prosthesis being developed, mounted on the implant holder, as well as the dilatation balloon of its own design, were used as the objects of the study. The bioprosthesis «UniLine» of 21 mm size for the aortic position was chosen as the target site of implantation, which was established by the «classical» suture method. After that, the implantation of the tested device was carried out as a «valve in valve» and the quality of the installation and the combined operation of all the components of the re-prosthesis system were evaluated.Results. The test implantation demonstrated the consistency of the proposed method on the basis of balloon seamless fi xation, as well as high ergonomic characteristics: the average time of seamless implantation of the developed prototype on an in vitro animal heart model was 3 minutes versus the implantation of the «UniLine» bioprosthesis – 11 min, Implantation provided a reliable prosthesis The breaking force was 12.9 N, which is equivalent to a pressure of 279 mm Hg.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
