The Editorial Board is pleased to announce the appointment of Dr. Alberto Benchimol as Editor of the Department, Graphic Techniques in Cardiology. Dr. Benchimol received his M.D. degree in 1956 from the National Medical School, University of Brazil, Rio de Janeiro. His postgraduate training included fellowships at the University of Kansas Medical Center, Kansas City, and the Scripps Institute Clinical and Research Foundation, La Jolla. He was appointed Associate at the institute in 1963. Since 1966, Dr. Benchimol has been Director, Institute for Cardiovascular Diseases, Good Samaritan Hospital, Phoenix, Arizona. Dr. Benchimol has been a member of the Editorial Board of the American Heart Journal since 1968 and a member of the Editorial Board of the American Journal of Cardiology since 1969. He has lectured throughout the United States in the disciplines of cardiovascular disease and cardiovascular physiology and has written numerous articles which have contributed significantly to advances in cardiology. He is a distinguished educator and investigator.

A technique was developed for closed-chest bypass of the right ventricle. Blood is removed from the right atrium and returned into the pulmonary artery. The blood return cannula can be inserted without x-ray equipment. The maximum flow through the system is ten liters per minute. Acute right ventricular failure produced by embolization of pulmonary arteries with starch could be treated promptly and repeatedly with the bypass. In six out of eight failure periods, the right ventricle had recovered after only five minutes of bypass. Progressive decrease of the arterial oxygen saturation, inherent with diffuse pulmonary embolization, could not be reversed. During ventricular fibrillation, while the circulation was maintained with closed-chest left ventricular bypass (transarterial), right heart bypass could not substitute right heart function. The reasons for this failure were incompetence of the pulmonary artery and tricuspid valves and increase of pulmonary arterial resistance.
