OBJECTIVE We performed a review of a consecutive series of 487 patients undergoing the Ross operation to identify surgical techniques and clinical parameters that affect outcome. METHODS We performed a prospective review of consecutive patients from August 1986 through June 2002 and follow-up through August 2004. Patient age was 2 days to 62 years(More)
Sera mass spectrometry (MS) peak differences were analyzed from 35 ovarian cancer patients and 16 disease-free individuals. "Leave one out" cross validation was used to assign "% cancer peaks" in control and ovarian cancer sera samples. Sera MS discriminated stage I/II and stage III/V ovarian cancer patients versus controls with ROC curve area values of(More)
This study evaluated the usefulness of electrospray mass spectrometry to distinguish sera of early-stage pancreatic cancer patients from disease-free individuals. Sera peak data were generated from 33 pancreatic cancer patients and 30 disease-free individuals. A "leave one out" cross-validation procedure discriminated stage I/II pancreatic cancer versus(More)
Goals of this study were to analyze the ability of mass spectrometry serum profiling to distinguish non-small cell lung adenocarcinoma from squamous cell carcinoma patients and healthy controls. Sera were obtained from 19 adenocarcinoma patients, 24 squamous cell carcinoma patients, and 21 controls. Identifications of significant mass-to-charge ratio (m/z)(More)
In a study comparing indium-111 platelet scintigraphy and two-dimensional echocardiography as methods of identifying left ventricular thrombi, the results obtained with both techniques were verified at surgery or autopsy in 53 patients--34 with left ventricular aneurysms, and 19 with mitral-valve disease. Left ventricular thrombi were found at surgery or(More)
Clinical pulmonary embolic disease was categorized into four classes according to hemodynamic and respiratory effects of the occlusion at the time of diagnosis. A new approach to management of massive embolization (Class III and IV) by transvenous catheter embolectomy was attempted in ten patients with initial success in eight. Three additional deaths(More)
Twenty-five low birth weight, premature neonates who were refractory to aggressive medical management underwent ligation of symptomatic patent ductus arteriosus. The mean birth weight was 1,007 g and the mean gestational age 29 weeks. Six patients (24 percent) died before discharge, two from continued cardiorespiratory failure. Echocardiography showed(More)
