OBJECTIVE To describe a clinicopathologic study of a large group of congenitally bicuspid aortic valves surgically excised at a single institution. MATERIAL AND METHODS The medical charts and bicuspid valves from patients undergoing aortic valve replacement at Mayo Clinic Rochester between 1991 and 1996 were retrospectively reviewed. RESULTS The age of(More)
BACKGROUND Disruptions in surgical flow have the potential to increase the occurrence of surgical errors; however, little is known about the frequency and nature of surgical flow disruptions and their effect on the etiology of errors, which makes the development of evidence-based interventions extremely difficult. The goal of this project was to study(More)
BACKGROUND Factors predicting long-term survival and reoperative risk after mitral valve repair for subsets with prolapse involving the anterior leaflet in the current era are unclear. METHODS Between January 1, 1980 and December 31, 1999, surgical correction of mitral regurgitation was performed in 2,219 patients. We analyzed a subset of 1,411 patients(More)
From 1975 to 1991, 112 patients (64 men and 48 women) were found to have an epiphrenic diverticulum. Symptoms were absent or minimal in 71 patients and incapacitating in 41. All patients with minimal symptoms were managed conservatively; 35 were available for follow-up, which ranged from 1 to 25 years (median, 9 years). None of these 35 patients had(More)
BACKGROUND Use of the left internal mammary artery (LIMA) in multivessel coronary artery disease improves survival after coronary artery bypass graft surgery; however, the survival benefit of multiple arterial (MultArt) grafts is debated. METHODS AND RESULTS We reviewed 8622 Mayo Clinic patients who had isolated primary coronary artery bypass graft(More)
INTRODUCTION The RIFLE (risk, injury, failure, loss of kidney function, and end-stage renal failure) classification for acute kidney injury (AKI) was recently modified by the Acute Kidney Injury Network (AKIN). The two definition systems differ in several aspects, and it is not clearly determined which has the better clinical accuracy. METHODS In a(More)
BACKGROUND The relative importance and interrelationship of risk factors for posttransplantation lymphoproliferative disorder are poorly understood. METHODS The prospective pretransplantation serologic testing for Epstein-Barr virus of all nonrenal solid organ transplant recipients at our institution made it possible to assess the relative risk for(More)
OBJECTIVE To assess outcome of valve repair in patients with aortic valve regurgitation with emphasis on incidence and risk of reoperation. METHODS We retrospectively reviewed 160 consecutive patients (127 men) who underwent aortic valve repair between 1986 and 2001. Ages ranged from 14 to 84 years (mean 55 +/- 17 years). Patients were categorized(More)
BACKGROUND Cardiac allograft vasculopathy (CAV) is primarily immune-mediated. We investigated the role of cellular rejection in CAV development. METHODS The study comprised 252 cardiac transplant recipients (mean age, 49.02 +/- 17.05 years; mean follow-up, 7.61 +/- 4.49 years). Total rejection score (TRS) based on the 2004 International Society of Heart(More)
Between 1965 and 1989, 96 consecutive patients (64 men and 32 women) underwent complete pulmonary resection for metastatic renal cell carcinoma. Median age was 63 years (range, 33 to 82 years). Median time between nephrectomy and pulmonary resection was 3.4 years (range, 0 to 18.4 years). Forty-eight patients had solitary metastasis, 16 had two, 18 had(More)
