Various Aspects of the Multipolarity within the World Economic System

The key aspects of the world economy’s transformation in the context of the multipolar world formation are studied in the article. Various kinds of economic multipolarity are analyzed. There is specially emphasized the wide range of multipolarity’s forms except the classical form concerning the competitive interactions of great powers. The particular role of financial and industrial sectors in the formation of the «branch growth poles»is considered in detail. Specific attention is paid to the growing influence of the regional leaders and strengthening positions of developing countries within the world economic system.The reinforcing influence of the regional and transregional integration groups is underlined. The key economic tendencies concerning the vectors of reshaping of the world geo-economic alignment of forces in the nearest future are examined in the article. There is also demonstrated the global economic and political reluctance of developed countries (especially Anglo-Saxon ones) to the objective process of a gradual dispersal of geo-economic influence within the world economy.

Palliative reconstruction of right ventricular outflow tract by using femoral vein allograft in a newborn with hypoplastic pulmonary artery and ventricular septal defect: case report

Treating patients with pulmonary atresia and ventricular septal defect, who have hypoplastic native pulmonary arteries, is a challenge for cardiac surgeons. We have reported a case of successful pulmonary bed rehabilitation using a femoral vein allograft in a patient with pulmonary atresia and ventricular septal defect. No similar cases with a detailed description of surgery stages and pulmonary artery development supported by illustrative materials are described both in the literature. The strategy of rehabilitation of the native pulmonary artery bed facilitates antegrade pulmonary blood flow, increases native pulmonary arteries growth, contributes to successful implementation of staged endovascular interventions and allows for complete repair. The technique of “short” cardiopulmonary bypass with induced ventricular fibrillation is a safe and effective option for such patients. This clinical case might be useful in medical practice of pediatric cardiac surgeons involved in the problem of pulmonary artery rehabilitation.Received 4 June 2018. Revised 4 July 2018.
