BACKGROUND Attempts to identify noninvasive markers of ventricular dysfunction accompanying acute rejection have been hampered by a lack of detailed simultaneous hemodynamic data. Therefore, we prospectively performed serial monitoring of detailed left and right heart hemodynamic parameters in cardiac transplant recipients at the time of routine(More)
OBJECTIVES The primary objective of this study was to determine outcomes in left ventricular assist device (LVAD) patients older than age 70 years. BACKGROUND Food and Drug Administration approval of the HeartMate II (Thoratec Corporation, Pleasanton, California) LVAD for destination therapy has provided an attractive option for older patients with(More)
Immunofluorescent techniques were utilized to identify the types of infiltrating lymphocytes adjacent to human malignant tumors arising from a wide range of anatomic sites. 24 of 29 primary tumors and 5 of 8 metastatic lesions showed varying degrees of lymphocytic infiltration. T cells predominated in the infiltrates in primary tumors (mean 80%, range(More)
To analyze whether atherosclerotic risk factors, including systemic hypertension, an elevated serum cholesterol level, smoking and diabetes, were associated with the presence of aortic stenosis (AS) in adults, 105 adults who had AS without coronary artery disease (CAD) were compared with 110 control subjects who had other types of valvular disease, 170(More)
BACKGROUND Aortic valve integrity is crucial for optimal left ventricular assist device (LVAD) support. Pre-existing native aortic insufficiency, aortic valve incompetence acquired during support, as well as previously placed prosthetic aortic valves present unique problems for these patients. METHODS We reviewed and analyzed data for 28 patients who(More)
Most centers consider medically unresponsive pulmonary hypertension an absolute contraindication to orthotopic cardiac transplantation because the alternative surgical therapy, heterotopic graft placement, is associated with decreased survival, although most patients normalize their pulmonary hemodynamics postoperatively. Orthotopic transplantation in(More)
To determine the predictors of surgically correctable aortic stenosis in patients with systolic murmurs, 231 patients were evaluated. Five variables (carotid upstroke timing, carotid upstroke volume, aortic valve calcification on chest radiography, single or absent second heart sound, and a murmur with its maximal intensity at the right upper sternal(More)
BACKGROUND Patients with advanced heart failure may require long-term support with an intracorporeal left ventricular assist device (LVAD) before cardiac transplant, while awaiting myocardial recovery, or during destination therapy. Compared with the diagnosis of native heart dysfunction, there is less experience with the assessment of recurrent heart(More)
BACKGROUND Ultrafiltration (UF) can rapidly and predictably remove extracellular and intravascular fluid volume. To date, assessment of UF in patients with cardiovascular disease has been confined to short- and medium-term studies in patients with a principal diagnosis of acute heart failure. METHODS In-hospital and long-term outcomes were reviewed from(More)
