OBJECTIVES Cell therapy may offer novel therapeutic options for chronic ischemic heart disease. In a clinical trial, we first assessed the feasibility and safety of intramyocardial CD133+ bone marrow cell injection together with coronary artery bypass grafting (CABG). We then tested the hypothesis that CABG plus CD133+ cell injection would result in better(More)
Between 43,000 and 47,000 people die annually in the United States from diseases of the aorta and its branches and continues to increase. For the thoracic aorta, these diseases are increasingly treated by stent-grafting. No prospective randomized study exists comparing stent-grafting and open surgical treatment, including for disease subgroups. Currently,(More)
BACKGROUND Patency or thrombosis of the false lumen in type B acute aortic dissection has been found to predict outcomes. The prognostic implications of partial thrombosis of the false lumen have not yet been elucidated. METHODS We examined 201 patients with type B acute aortic dissection who were enrolled in the International Registry of Acute Aortic(More)
BACKGROUND Studies of aortic aneurysm patients have shown that the risk of rupture increases with aortic size. However, few studies of acute aortic dissection patients and aortic size exist. We used data from our registry of acute aortic dissection patients to better understand the relationship between aortic diameter and type A dissection. METHODS AND(More)
AIMS This article summarizes all available published data with respect to clinical success, complications, and outcomes of endovascular stent-graft placement among patients with descending aortic dissection (AD). METHODS AND RESULTS We performed a meta-analysis of all published series on retrograde endovascular stent-graft placement encompassing >or=3(More)
BACKGROUND Experimental and clinical evidence has recently shown that pluripotent stem cells can be mobilized by granulocyte colony-stimulating factor (G-CSF) and may enhance myocardial regeneration early after primary percutaneous coronary intervention (PCI) management of acute myocardial infarction. Sustained or long-term effects of mobilized(More)
Cardiovascular disease is the leading cause of death in most Western societies and is increasing steadily in many developing countries. Aortic diseases constitute an emerging share of the burden. New diagnostic imaging modalities, longer life expectancy in general, longer exposure to elevated blood pressure, and the proliferation of modern noninvasive(More)
An expert multidisciplinary panel in the treatment of type B aortic dissection reviewed available literature to develop treatment algorithms using a consensus method. Data from 63 studies published from 2006 to 2012 were retrieved for a total of 1,548 patients treated medically, 1,706 patients who underwent open surgery, and 3,457 patients who underwent(More)
Implantation of bone-marrow stem cells in the heart might be a new method to restore tissue viability after myocardial infarction. We injected up to 1.5x10(6) autologous AC133+ bone-marrow cells into the infarct border zone in six patients who had had a myocardial infarction and undergone coronary artery bypass grafting. 3-9 months after surgery, all(More)
