Marian Ion Ionescu (born 21 August 1929) is a pioneering British cardiac surgeon who spent his professional life initially in his native Romania and afterwards, the main part of his productive life, in Great Britain. His interest in heart surgery covered several aspects of this speciality.〔Shumacker H B Jr. ''The Evolution of Cardiac Surgery.''Indiana University Press (1992), Bloomington, Indianapolis. pages 199,269,310,313–315 ISBN 0-253-35221-5〕 He was an inventor of surgical devices, mostly artificial heart valves,〔Westaby S, Bosher C,''Landmarks in Cardiac Surgery.''ISIS Medical Media, (1997) Oxford,pages 157–159,168, ISBN 1-899066-54-3,〕 a scientist in the broad term and a medical educator.〔''125th Anniversary Exhibition at The General Infirmary at Leeds since the opening of the Gilbert Scott Building 1868–1993'' |() Woodgate Graphic Design Consultants, Leeds.〕 In addition to his interests in literature and philosophy, his main passion was and remains high altitude mountain climbing. ==Early life and medical career== Marian Ionescu's complex, adventurous and arduous life started in a small medieval town (Targoviste) in the shadow of the Carpathian Mountains where, during his high school years, he discovered the beauty of literature, the wonders of science and the magic and mystery of the mountains. He attended medical school at the University of Bucharest and graduated in 1954. At this time he married Christina Marinescu, a medical school colleague who specialised in cardiology. Throughout their life she was a continuous support and played an important role in his later discoveries and inventions. Following compulsory work as a general practitioner in rural areas, Ionescu obtained a World Health Organisation fellowship for cardiac surgery in the United States of America. During 1958 and 1959 he spent time at the Mayo Clinic with Dr D.C.McGoon, and at the Cleveland Clinic with Dr D.B.Effler in the clinical service, and with Dr W. Kolff in the Laboratory for Artificial Organs. Following this unique experience, he returned in 1964 to 'the source of real knowledge' as he used to call the United States. He spent more time at the Cleveland Clinic and at the Texas Heart Institute for further experience in heart surgery with Dr Denton A. Cooley. Upon his return to Romania in 1960 he was appointed Consultant Cardiovascular Surgeon at Fundeni Hospital in Bucharest. In 1961 he became Chief of the Department of Cardiovascular Surgery and head of the Laboratory for Artificial Organs which he created and developed into a modern and efficient laboratory for research and experimental surgery. In a short time he built an intensive care unit and transformed the Department of Cardiovascular Surgery into a modern and very active cardiac surgical unit. The first open heart procedures with extracorporeal circulation were performed at the beginning of 1962. During the years 1961 to 1965 Ionescu found himself to be progressively and severely constrained, not only by the lack of surgical material which could not be imported from abroard, but mainly by the increasingly complicated communist dictatorial Romanian political situation and by what his distant Roman ancestors would have called 'invidia medicorum pessima'.Finally frustrated by all these impediments and mainly by increasing political pressure, the Ionescus decided to make the bold and dangerous move to escape 'illegally' from Romania to the west. In the summer of 1965, in a little Fiat 600 car with nothing but two suitcases, a few books and some cans of reserve petrol, they took the risk to cross the frontiers to Yugoslavia and to Italy during moonless nights, and to reach Italy nationless and homeless but 'free'. This saga continued until they reached Paris where loyal and generous friends found them jobs for survival. Ionescu obtained a position in cardiothoracic surgery at Hôpital St. Joseph as 'locum intern', but in charge of most everything, especially at night and during the weekends. His wife got a similar position in cardiology at the Institute National du Sport. Less than one year later Mr G.H.Wooler, a surgeon in Leeds, learned about their escape from Romania and, in search himself of a cardiac surgeon to bolster his fledgling unit at the Leeds General Infirmary, invited the Ionescus to come to England, and helped them to join his unit where they were able to work and develop their many original ideas. As it transpired, this was a seminal move, not only for the Ionescus but for the advancement of cardiac surgery in general. The Ionescus would spend a quarter of a century in Leeds. That time was the most prolific and productive period for the Ionescus and for Leeds. In 1968 Ionescu, following a complex examination, became Licentiate of the Apothecaries Hall of Dublin. In 1971 he was appointed Consultant Cardiothoracic Surgeon at the General Infirmary at Leeds, at Killingbeck Hospital Leeds and Reader in Surgery at Leeds University. Upon Mr Wooler's retirement in 1974, Ionescu became the Chief of the Department of Cardiothoracic Surgery. He was later appointed as Consultant to the Ministry of Health (United Kingdom) for matters related to artificial heart valves. The cardiac surgical unit in Leeds became one of the most productive centres in Great Britain which attracted a considerable number of overseas surgeons for further training or for scientific visits. During his entire life as an active cardiac surgeon, Ionescu made significant and original contributions to cardiovascular science in several fields. He has been a prolific writer, a medical educator and a tireless speaker.His opinions, which were based on his vast knowledge of literature and philosophy, often generated interesting discussions and occasionally heated but healthy debate. He is a highly respected senior figure in international cardiac surgical circles. In 1987 he retired from active surgical work〔Gonzalez-Lavin L. (1988) "Letter to the editor, on the retirement of Marian I. Ionescu from clinical practice." ''Journal of Cardiac Surgery,''3,1,85–86 |(),〕 and despite some health problems he pursues his lifelong passion for high altitude mountain climbing. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Marian Ionescu」の詳細全文を読む スポンサード リンク
