Filter by:A new hand held pocket echo device (GE Vscan) has now become available to clinicians, with limited data available comparing the effectiveness of this device as a screening tool when compared to traditional transthoracic echocardiography (TTE). The investigators are evaluating the effectiveness of this hand-held echo (HHE) device in detecting cardiac pathology in a both an inpatient and outpatient clinical setting as compared to a comprehensive TTE evaluation.
This randomized pilot clinical trial studies how well positron emission tomography (PET)-magnetic resonance imaging (MRI) works compared to standard-of-care PET-computed tomography (CT) in diagnosing patients with cancer, cardiac diseases, or neurologic diseases. PET-MRI combines two imaging methods that can be used to evaluate disease. PET-MRI is similar to standard-of-care PET-CT, but exposes the patient to less radiation. It is not yet known whether PET-MRI produces better image quality than PET-CT in diagnosing patients with cancer, cardiac disease, or neurologic disease.
Using the 9 centers (Appendix B) involved with the planned multicenter NIRS comparative effectiveness trial the specific aims of this study are: 1. To demonstrate the feasibility of collecting rScO2 data from patients undergoing cardiac surgery in a multicenter study design. 2. To demonstrate the feasibility of using a standard algorithm for treating rScO2 desaturations during cardiac surgery in a multicenter study design.
Delirium after cardiac surgery is reported in a range of 3-47% of patients. Delirium is a serious complication that results in prolonged length of stay, increased health care costs and is associated with higher death rates. The exact cause involved in the development of delirium after cardiac surgery is unclear. The latest advancement in near-infrared spectroscopy (NIRS) Oximetry offers real-time management of patients at risk of brain injury. This approved device will monitor cerebral oxygenation during and 24hr after cardiac surgery, recording oxygenation in real time allowing the clinical team the opportunity to intervene early to prevent ischemia and possibly preventing untoward events. Adverse events followed include, but are not limited to, stroke, (transient ischemic attacks), heart attack, (myocardial infarction), clots found in lungs (pulmonary embolism), kidney failure, pneumonia, cause of death for 30-days after surgery (all cause mortality). Hypothesis: Perioperative restoration of rSO2 desaturation to baseline values results in lower delirium rates after complex cardiac surgery.
Cardiac output (CO) is an important hemodynamic variable in the management of critically ill patients. The pulmonary artery catheter (PAC) requires invasive techniques with potential complications and there is increasing interest in less invasive methods of measuring CO. This study is designed to compare CO values from PAC thermodilution (COTD) and ultrasound dilution (COUD).
Cardiopulmonary bypass surgery is associated with extensive blood loss in upto 20% of patients. Tranexamic acid (TXA) is a routinely administered antifibrinolytic agent that reduces blood loss and blood transfusion requirement. However, standard dosing of TXA in patients suffering from renal dysfunction and undergoing cardiopulmonary bypass surgery may lead to higher blood concentration of TXA when compared to the patients with normal renal function. Solid phase microextraction (SPME) is a fast and simple method to measure TXA levels. This prospective study on cadiac surgical patients undergoing cardiopulmonary bypass aims to study the pharmacokinetics of TXA in patients with renal dysfunction. Two patient groups will be studied who will receive either TXA 50mg/kg bolus or BART regimen (30 mg/kg, 16 mg/kg/h + 2 mg/kg pump prime) depending on the type of cardiac surgical procedure and bleeding risk. Hypothesis: Standard dosing of TXA used in cardiac surgery result in higher blood concentration of TXA in patients with renal dysfunction when compared to patients with normal renal function.
The objective of the CELT ACD® Vascular Closure Device study is to evaluate the safety and effectiveness of the CELT ACD® device to achieve hemostasis of the common femoral artery access site in patients on anticoagulation who are undergoing a percutaneous coronary intervention (PCI) procedure using either a 6F or 7F procedural sheath.
The purpose of this study is the evaluation of safety and efficacy of the pacemaker lead "Setrox JS".
The objective of this study is to investigate the safety and efficacy of the Lumax DX / Linox DX system. No hypothesis has been defined.
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
