BACKGROUND Studies have found that cardiac surgery patients receiving blood transfusions are at risk for increased mortality during the first year after surgery, but risk appears to decrease after the first year. This study compared 5-year mortality in a propensity-matched cohort of cardiac surgery patients. STUDY DESIGN AND METHODS Between July 1, 2004,(More)
OBJECTIVES Prior studies have found that cardiac surgery patients receiving blood transfusions are at risk for increased mortality and morbidity following surgery. It is not clear whether this increased risk occurs across all haematocrit (HCT) levels. The goal of this study was to compare operative mortality in propensity-matched cardiac surgery patients(More)
OBJECTIVE The left atrial appendage (LAA) is the source of 90% of thrombi in patients with atrial fibrillation. Our double LAA ligation (LLAA) technique was shown to be 96% successful in a small study. However, the outcomes of these patients have yet to be compared with a set of nonligated patients. METHODS From 2005 to 2012, a total of 808 patients(More)
OBJECTIVES Utilization of bilateral internal mammary arteries (BIMAs) has been shown to improve long-term outcomes in patients undergoing coronary artery bypass grafting. To achieve complete revascularization, BIMAs may be used as either sole conduits for revascularization through a Y-graft configuration (BIMA-Y) or deployed with additional grafts used in(More)
Hyperplastic polyps are by far the most common benign tumors in the stomach larger than 5mm. Although the malignant potential of hyperplastic gastric polyps was originally denied, a low risk for carcinomatous conversion is now recognized. Its has been recommended that all gastric polyps of 5mm or more in diameter have to be removed. We present here the case(More)
Worse prognosis of IgA nephropathy (IgAN) is associated to hypertension, high proteinuria, glomerular and vascular sclerosis. A family story of hypertension (FHT) in relatives could be a strong predictor of the occurrence of hypertension (HT) in children. Renal vascular lesions (RVL) are often observed in normotensive patients with IgAN. In order to(More)
