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 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)
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 This study evaluated long-term results of aortic root replacement and valve-preserving aortic root reconstruction for patients with aneurysms involving the aortic root. METHODS AND RESULTS Two-hundred three patients aged 53+/-16 years (mean+/-SD; 153 male, 50 female) underwent elective or urgent aortic root surgery from 1971 to 2000 for an(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)
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 Mitral regurgitation (MR) may develop in patients with advanced systolic congestive heart failure (CHF) without organic mitral valve disease and contribute to worsening symptoms and survival. Surgical mitral annuloplasty improves symptoms in patients with advanced CHF, and percutaneous approaches to mitral annuloplasty are being developed. Our(More)
BACKGROUND Primary cardiac tumors are rare but have the potential to cause significant morbidity if not treated in an appropriate and timely manner. To date, however, there have been no studies examining survival characteristics of patients who undergo surgical resection. METHODS AND RESULTS From 1957 to 2006, 323 consecutive patients underwent surgical(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)
Analysis of 164 percutaneous chest tube thoracostomies performed as a standardized technical procedure in the management of 129 blunt trauma victims demonstrated an overall complication rate of 9.1% (15 of 164). Three complications (1.8%) were related to problems of insertion, and four (2.4%) represented the problem of pneumothorax after chest tube removal.(More)
