OBJECTIVE To (1) characterize atrial fibrillation complicating lung cancer resection, (2) evaluate its temporal relationship to other postoperative complications, and (3) assess its economics. METHODS From January 1998 to August 2002, 604 patients underwent anatomic lung cancer resection. Atrial fibrillation prevalence, onset, and temporal associations(More)
BACKGROUND Increased life expectancy and younger patients' desire to avoid lifelong anticoagulation requires a better understanding of bioprosthetic valve failure. This study evaluates risk factors associated with explantation for structural valve deterioration (SVD) in a long-term series of Carpentier-Edwards PERIMOUNT aortic valves (AV). METHODS From(More)
BACKGROUND Recent US and European registries have indicated 30% to 60% of patients with critical valvular aortic stenosis (AS) are not treated surgically, usually due to advanced age and comorbidities. We report on a Food and Drug Administration approved feasibility study of a less invasive transcatheter approach to potentially treat these high-risk(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)
OBJECTIVE Percutaneous aortic valve replacement is an emerging therapy for selected patients with severe aortic stenosis. Preoperative imaging of the aortic root facilitates sizing and deployment of the percutaneous aortic valve replacement device. We compared morphologic characteristics of the aortic root in patients with aortic stenosis versus elderly(More)
BACKGROUND Computed tomography (CT) imaging has not been systematically studied for predicting vascular complications during transcatheter aortic valve replacement (TAVR). METHODS Clinical data were obtained from the electronic medical record and analysis was performed for each individual patient's iliofemoral CT angiogram. Sheath : femoral artery(More)
BACKGROUND Coronary transplant vasculopathy (CAV) has been associated with both immunologic and nonimmunologic factors. The impact of preoperative ventricular assist device (VAD) support on the development of CAV has not been studied. To examine this, we obtained posttransplant coronary angiograms from a group of patients bridged with VAD and compared them(More)
OBJECTIVES We sought to examine whether contrast-enhanced multidetector row computed tomography (MDCT) allows prediction of X-ray angiographic planes for the root angiogram in the context of transcatheter aortic valve implantation. BACKGROUND Understanding of aortic root orientation relative to the body axis is critical for precise positioning of the(More)
BACKGROUND Endovascular repair of thoracic aneurysm has demonstrated low risks of mortality and spinal cord ischemia (SCI), but few large series have been published on endovascular thoracoabdominal aneurysm repair, and reports suffer from a lack of accurate comparison with similar open surgical procedures. METHODS AND RESULTS A consecutive cohort of(More)
OBJECTIVE To compare explantation for structural valve deterioration in nonelderly patients after aortic valve replacement with stented bovine pericardial and cryopreserved allograft valves. METHODS From 1981 to 1985, 478 patients received pericardial prostheses during premarket approval; from 1987 to 2000, 744 patients received cryopreserved allografts.(More)
