BACKGROUND Coronary slow flow phenomenon (CSFP) is defined as delayed coronary opacification in the absence of obstructive coronary artery disease. In the present study, we sought to define its prevalence and clinical features. METHODS AND RESULTS The 1,741 consecutive patients who underwent coronary angiography (CAG) were identified. Those with normal(More)
BACKGROUND Autopsy studies consistently demonstrate cardiac involvement in thrombotic thrombocytopenic purpura (TTP), but clinical evidence for cardiac abnormalities is rarely reported. STUDY DESIGN AND METHODS This systematic review addresses the apparent discrepancy between autopsy and clinical data. English language articles were identified by keywords(More)
The transition to pulmonary respiration following birth requires rapid alterations in the structure of the mammalian cardiovascular system. One dramatic change that occurs is the closure and remodeling of the ductus arteriosus (DA), an arterial connection in the fetus that directs blood flow away from the pulmonary circulation. A role for prostaglandins in(More)
BACKGROUND Venous thromboembolism contributes significantly to morbidity and mortality in cancer patients. Because cancer patients frequently have contraindications to anticoagulation, inferior vena cava filters are commonly placed. The use, safety, and retrieval of retrievable inferior vena cava filters in cancer patients have not been well studied. (More)
OBJECTIVES Our goal was to describe a single-center's experience in managing acute and chronic mesenteric ischemia with endovascular therapies. BACKGROUND Open surgical revascularization has been considered the historical gold standard treatment for mesenteric ischemia though it poses considerable morbidity and mortality risk. An aging population with(More)
OBJECTIVES The aim of this study was to compare the stroke/death rates between proximal embolic protection devices (P-EPDs) and distal filter embolic protection devices (F-EPDs) in elective carotid artery stenting (CAS). BACKGROUND P-EPDs have theoretical advantages that may make them superior to F-EPDs for stroke prevention during CAS. METHODS We(More)
Recent studies have highlighted differences in how older patients respond to high-risk pulmonary embolism (PE) and treatment. However, guidelines for PE risk stratification and treatment are not based on age, and data are lacking for older patients. We characterized the impact of age on clinical features, risk stratification, treatment, and outcomes in a(More)
OBJECTIVES We developed and internally validated a risk score to predict in-hospital stroke or death after carotid artery stenting (CAS). BACKGROUND A tool that accurately assesses CAS risk could aid clinical decision making and improve patient selection. METHODS Patients undergoing CAS without acute evolving stroke from April 2005 through June 2011 as(More)
Retrievable inferior vena cava filters (IVCFs) were designed to provide temporary protection from pulmonary embolism in high-risk situations. However, little is known about their effectiveness, and many remain permanently implanted, leading to potential complications. The aim of this study was to determine patient characteristics, indications for IVCF(More)
OBJECTIVES This study sought to characterize usage and outcomes of carotid stenting platforms. BACKGROUND A variety of stents and embolic protection devices (EPDs) are used for carotid artery stenting. Little is known about current usage patterns and differences in outcomes with these devices. METHODS We analyzed 12,135 consecutive carotid stent(More)
