Journal ArticleDOI
Autotransfusion of shed mediastinal blood after cardiac surgery: A prospective study
Hartzell V. Schaff,Jerome Hauer,William R. Bell,Timothy J. Gardner,James S. Donahoo,Vincent L. Gott,Robert K. Brawley +6 more
TL;DR: In this study, autotransfusion of shed mediastinal blood was safe and simple, it significantly reduced bank blood requirements and resulted in substantial financial savings for the patients and the hospital.
Journal ArticleDOI
Clinical and Hemodynamic Evaluation of the 19 mm Björk-Shiley Aortic Valve Prosthesis
Hartzell V. Schaff,A. Michael Borkon,A. Michael Borkon,Clifford Hughes,Clifford Hughes,Stephen C. Achuff,James S. Donahoo,James S. Donahoo,Timothy J. Gardner,Timothy J. Gardner,Levi Watkins,Levi Watkins,Vincent L. Gott,Andrew G. Morrow,Andrew G. Morrow,Robert K. Brawley +15 more
TL;DR: For patients with smallAortic roots, aortic valve replacement with the 19 mm Björk-Shiley valve is a satisfactory and, perhaps, preferable alternative to aortIC annuloplasty to accommodate larger sized prostheses.
Journal ArticleDOI
Comparison of regional myocardial blood flow and metabolism distal to a critical coronary stenosis in the fibrillating heart during alternate periods of pulsatile and nonpulsatile perfusion
TL;DR: Fibrillation-induced regional ischemia distal to a critical coronary stenosis can be reduced by pulsatile perfusion during bypass and the mechanism for the reduction in regional isChemia is improved myocardial blood flow.
Journal ArticleDOI
Myocardial ischemia during cardiopulmonary bypass. The hazards of ventricular fibrillation in the presence of a critical coronary stenosis.
TL;DR: It is concluded that the myocardium distal to a critical stenosis suffers a progressive reduction in flow during ventricular fibrillation which does not occur in regions supplied by unstenosed coronary arteries.
Journal ArticleDOI
Influence of coronary artery anatomy on survival following resection of left ventricular aneurysms and chronic infarcts.
Robert K. Brawley,Hartzell V. Schaff,Rosemary Stevens,Hector Ducci,Vincent L. Gott,James S. Donahoo +5 more
TL;DR: It is concluded that the presence or absence of occlusive disease in the arteries supplying the LV lateral wall is an important determinant of the mortality rate associated with resection of anterior apical LV aneurysms in patients with severe congestive heart failure.
