BACKGROUND Intensity-modulated radiation therapy (IMRT) is a novel approach to the planning and delivery of radiation therapy. The prevalence of IMRT use among radiation oncologists in the U.S. appears to be increasing, despite limited data evaluating its risks and benefits. METHODS A random sample of radiation oncologists in the U.S., including a cohort(More)
Red blood cell distribution width (RDW), a widely available biomarker, independently predicts adverse outcomes in left-sided heart failure. The relation between RDW and death in pulmonary hypertension (PH) is unknown. In a prospective study of 162 consecutive patients with PH, RDW was recorded during initial diagnostic right-sided cardiac catheterization,(More)
UNLABELLED Study's purpose: Plasma levels of soluble receptor for advanced glycation endproducts (sRAGE) and S100A12 are increased in young children after cardiac surgery and correlate with the time spent on cardiopulmonary bypass (CPB). This study was performed to investigate whether plasma levels of sRAGE and S100A12 are affected by the use of CPB. Levels(More)
OBJECTIVES This study sought to assess the effectiveness of a novel percutaneous method to treat left ventricular assist device (LVAD)-associated severe aortic insufficiency (AI) in a series of patients determined to be poor reoperative candidates. BACKGROUND The increased use of continuous-flow LVAD in advanced heart failure has led to marked changes in(More)
The diagnosis of acute coronary syndrome relies on clinical history, electrocardiographic (ECG) changes, and cardiac biomarkers; but within the spectrum of acute coronary syndrome, there exist subtle presentations that cannot afford to be overlooked. Wellens syndrome is one such example, in which a patient can present with both ECG changes that are not(More)
Pulmonary arterial hypertension is a fatal disease. Intravenous prostanoids are often utilized for long-term management of patients. The therapy requires a significant commitment and change in lifestyle for both the patient and family. Takotsubo cardiomyopathy, transient apical ballooning syndrome, has been reported in association with emotional and(More)
BACKGROUND The Medtronic Sprint Fidelis defibrillator lead has a high failure rate and was recalled in October 2007. OBJECTIVE The purpose of this study was to determine the incremental cost of the management of this lead to Medicare. METHODS Real hospital cost data in U.S. dollars were collected on 32 patients with a Medtronic Sprint Fidelis lead who(More)
We report a case of a patient with pulmonary hypertension who presented with acute hypoxemic respiratory failure. The patient had continued refractory hypoxemia despite a prolonged ICU admission that included ventilatory support, and empiric therapy for pulmonary embolism and pneumonia. Transthoracic echocardiography (TTE) revealed a patent foramen ovale(More)
