We compared patients who received an internal-mammary-artery graft to the anterior descending coronary artery alone or combined with one or more saphenous-vein grafts (n = 2306) with patients who had only saphenous-vein bypass grafts (n = 3625). The 10-year actuarial survival rate among the group receiving the internal-mammary-artery graft, as compared with(More)
OBJECTIVE To relate morbidity and mortality risk to preoperative severity of illness in patients undergoing coronary artery bypass grafting. DESIGN Retrospective analysis of 5051 patients using univariate and logistic regression to identify risk factors associated with perioperative morbidity and mortality. Prospective application of models to a(More)
Of 6,504 consecutive patients who underwent isolated coronary bypass grafting in 1985 to 1987, 72 (1.1%) patients experienced sternal wound complications. Ten patients (14%) with wound complications died of multi-system failure. Only the patients with negative cultures fared well; of the bacterial culture categories, polymicrobial infection carried the(More)
BACKGROUND To compare survival of patients receiving bilateral internal thoracic artery grafts and single internal thoracic artery grafts more than 20 postoperative years, assess magnitude of benefit, and identify predictors of benefit. METHODS From cohorts of 8123 patients receiving single internal thoracic artery grafts and 2001 receiving bilateral(More)
OBJECTIVE Does the use of bilateral internal thoracic artery (ITA) grafts provide incremental benefit relative to the use of a single ITA graft? METHODS We conducted a retrospective, nonrandomized, long-term (mean follow-up interval of 10 postoperative years) study of patients undergoing elective primary isolated coronary bypass surgery who received(More)
OBJECTIVE Our objective was to quantify incremental risk associated with transfusion of packed red blood cells and other blood components on morbidity after coronary artery bypass grafting. DESIGN The study design was an observational cohort study. SETTING This investigation took place at a large tertiary care referral center. PATIENTS A total of(More)
BACKGROUND Perioperative red blood cell (PRBC) transfusion has been associated with early risk for morbid outcomes, but risk related to long-term survival has not been thoroughly explored. Therefore, we examined the influence of PRBC transfusion and component therapy on long-term survival after isolated coronary artery bypass grafting after controlling for(More)
BACKGROUND Degenerative mitral valve disease is the most common cause of mitral regurgitation in the United States. Mitral valve repair is applicable in the majority of these patients and has become the procedure of choice. OBJECTIVE This study was undertaken to identify factors influencing the durability of mitral valve repair. PATIENTS AND METHODS(More)
OBJECTIVE To evaluate long-term effectiveness of a strategy for managing the aortic root and distal aorta according to the pathology in ascending aortic dissection. METHODS From 1978 to 1995, 208 patients underwent operations for acute (n = 135) and chronic (n = 73) ascending aortic dissection. Surgical strategies included valve resuspension with(More)
BACKGROUND This study was performed to develop an intensive care unit (ICU) admission risk score based on preoperative condition and intraoperative events. This score provides a tool with which to judge the effects of ICU quality of care on outcome. METHODS Data were collected prospectively on 4,918 patients (study group n = 2,793 and a validation data(More)
