BACKGROUND Patients with advanced heart failure have improved survival rates and quality of life when treated with implanted pulsatile-flow left ventricular assist devices as compared with medical therapy. New continuous-flow devices are smaller and may be more durable than the pulsatile-flow devices. METHODS In this randomized trial, we enrolled patients(More)
Acute right ventricular (RV) failure is a frequent and serious clinical challenge in the intensive care unit. It is usually seen as a consequence of left ventricular failure, pulmonary embolism, pulmonary hypertension, sepsis, acute lung injury or after cardiothoracic surgery. The presence of acute RV failure not only carries substantial morbidity and(More)
Obliterative bronchiolitis (OB) post-lung transplantation involves IL-17-regulated autoimmunity to type V collagen and alloimmunity, which could be enhanced by complement activation. However, the specific role of complement activation in lung allograft pathology, IL-17 production, and OB is unknown. The current study examines the role of complement(More)
Ventricular arrhythmia (VA) is a significant factor in the clinical management of patients with congestive heart failure (CHF). Understanding the implications of VA in ventricular assist device-supported CHF patients is critical to appropriate clinical decision making in this special population. This article details research findings on this topic, and(More)
OBJECTIVE Leak after esophageal anastomosis or perforation repair prolongs hospitalization, prevents oral hydration and nutrition, and can produce localized infection or sepsis. This investigation reviews our experience treating postoperative esophageal leaks with the Polyflex esophageal stent (Boston Scientific, Natick, Mass). METHODS Over a 30-month(More)
BACKGROUND Plication of the hemidiaphragm for unilateral diaphragm paralysis is infrequently performed in adults. Barriers to diaphragm plication have included the perceived need for thoracotomy and uncertainty of the potential benefits. The purpose of this investigation was to assess the effects of video-assisted thoracoscopic diaphragm plication in(More)
Early risk-prediction is essential to prevent cardiac allograft vasculopathy (CAV) and graft failure in heart transplant patients. We developed multivariate models to identify patients likely to experience CAV, severe CAV, and failure due to CAV, at 1, 5 and 10 years. A cohort of 172 patients was followed prospectively for 6.7 ± 3.9 years. Logistic(More)
INTRODUCTION Cystic fibrosis (CF) is an inherited disorder that presents in childhood as a multisystem disease. Pulmonary failure and pancreatic insufficiency, including CF-related diabetes (CFRD) and exocrine insufficiency, are significant causes of morbidity and mortality in these patients. In this report we have reviewed our experience with a(More)
OBJECTIVES The purpose of this study was to determine the risk factors for ischemic in hemorrhage cerebrovascular events in patients supported by the HeartWare ventricular assist device (HVAD). BACKGROUND Patients supported with left ventricular assist devices are at risk for both ischemic and hemorrhagic cerebrovascular events. METHODS Patients(More)
Timing of surgical management of acute infective endocarditis is a major challenge, with respect to surgical complications, risks of recurrences and optimal valve repair or replacement. We present a case of a 24-year-old male with a history of intravenous drug abuse, who was referred to our center after 10 days of medical management of acute infective(More)
