Filter by:The purpose of the study is to evaluate the initial short and long-term safety and performance of the CardiAQ™ Transcatheter Mitral Valve Implantation System using the Transapical Delivery System. The study will enroll patients with moderate to severe mitral valve regurgitation who are considered high or extreme risk for mortality and morbidity from conventional open heart surgery.
A retrospective, multi-center, proof-of-concept study to evaluate the use of remote monitoring in rural emergency departments to decrease time to treatment decision for pacemaker and defibrillator patients using the St Jude Medical Merlin@home transmitter. The purpose of the study is to determine if utilization of remote monitoring technology in a rural emergency department may improve patient care. Up to 10 rural ED sites will enroll a total of 200 patients. One hundred patients will be in the remote monitoring group comprised of patients with SJM devices compatible with the unpaired transmitter and 100 patients will be in the usual medical care group comprised of patients with SJM devices that are not compatible with the unpaired transmitter or that have a competitor's device.
Cardiac rehabilitation is a program designed to help patients regain good health through lifestyle change after a heart attack, heart surgery or other heart problems. Patients will take part in exercise sessions and education lessons, tailored to meet their personal needs. The exercise training component of cardiac rehabilitation may be delivered as intervals of short intense sessions (also known as high intensity intervals) or the current standard care of longer but less intense sessions (moderate intense intervals). Both exercises have been shown to increase fitness levels and also prevent future risk of heart disease. The purpose of this study is to determine the efficacy and safety of high intensity interval exercise training (HIIT) in patients who had a recent cardiac revascularization procedure or recovering from a heart attack, in comparison to current standard of moderate intensity exercise training in terms of their physical fitness and psychological well-being.
A Relational Agent (RA) "virtual counselor" (VICKY: VIrtual Counselor for Knowing Your Family History) has been developed to collect family health history information for common health conditions including heart disease, stroke, diabetes, hypertension and various cancers. In this study, the investigators will conduct a randomized controlled trial (RCT) to compare the efficacy of using VICKY to the existing My Family Health Portrait (MFHP) tool for collecting family health history information among an underserved primary care patient population. The primary aims of the study are to 1) evaluate the efficacy of VICKY versus MFHP for collecting accurate family health histories and 2) determine whether accuracy varies as a function of health literacy. This project will obtain validation data on the efficacy of both VICKY and MFHP for collecting accurate family history data among an underserved patient population, in two languages (English and Spanish). The study will determine whether a virtual counselor can overcome many of the existing barriers to using traditional web-based family history tools.
Cardiovascular disease (CVD) is the leading cause of death in the U.S. Efforts to improve CVD risk factors often fall short in complex patients with multiple co-morbid conditions, a growing, expensive, and high-risk segment of the U.S. population. The investigators are testing a multi-component behavioral intervention designed to help complex patients with CVD and other concurrent chronic conditions to become more effective agents of their own care.
Safety and Efficacy Study in pediatric subjects aged 9 to 17 years of age with suboptimal LV EBD on non-contrast 2D echocardiography. Imaging modalities that are used throughout the study in pediatric subjects represented those utilized in routine clinical practice in adults.
Excessive bleeding after cardiopulmonary bypass (CPB) operations remains to be a persistent problem. Antiplatelet therapy (APT) is an integral component of perioperative management in patients undergoing cardiac surgery. The impact of drug induced platelet inhibition on early postoperative bleeding extent and transfusion requirements remains difficult to predict. In addition to, resistance to antiplatelet drugs as well as perioperative increase in platelet reactivity following CPB has been reported but this phenomenon has to be comprehensively investigated. The best point-of-care platelet function test to predict bleeding complications/transfusion requirements remains unclear. In addition to, the best test platelet function test to monitor resistance to antiplatelet therapy and its impact on clinical outcomes remains elusive. The aim of this study is: 1. to compare two point-of-care platelet function analyzers (Multiplate and ROTEM Platelet) in regard to prediction of bleeding complications/trasfusion requirements. 2. to compare two point-of-care platelet function analyzers (Multiplate and ROTEM Platelet) in regard to detection of high "on-treatment" platelet reactivity both pre- and postoperatively.
The purpose of this randomized trial is to clarify the role of enteral nutrition (EN) on the relationship between cardiopulmonary bypass-induced inflammation and insulin resistance by investigating the effects of two different feeding strategies in infants following cardiac surgery. The study's primary objective is to determine if early and higher volume feeding modifies the relationship between the severity of postoperative systemic inflammation and insulin resistance.
Background: The prevalence of both senile cardiac amyloidosis (CA) and aortic stenosis (AS) markedly increases with age. Aortic stenosis increases left ventricular pressure overload. Cardiac deposits have been observed in AS and the amount of these deposits has been correlated to post-surgical outcome. As they are strong echocardiographic and cardiac MRI imaging similarities between CA and AS, the investigators hypothesized that the deposit observed in AS is transthyretin amyloid deposit. The investigators objective is to demonstrate that amyloid deposit is associated with poor outcomes following aortic stenosis surgical valve replacement. Materiel and methods: 180 patients with indication for surgical aortic valve replacement will be recruited prospectively and consecutively in 5 French centers. A replicative study will be performed in one Austrian center. Echocardiography, cardiac MRI and bone scintigraphy will be performed prior to surgery. During surgery, a basal LV septum biopsy will be collected for determination and quantification of interstitial deposits using specific staining which will be performed in a blind fashion. Clinical outcomes will be recorded during the hospitalization period following the surgery and at 1 year. Alive and re-hospitalization status will be determined. Patients will be classified according to the presence or not of amyloid deposits. Expected results and impact: This study will emphasize how pressure overload stress accelerates and magnifies amyloid deposition usually known to be related to cardiac aging process. It will develop reliable imaging tools and markers to detect cardiac amyloid deposition. Correlation between anatomopathologic analyses and the three different imaging technics will identify accurate imaging markers of CA. A risk stratification model based on amyloid deposits level for the clinical management of these patients will be created combining imaging and biological markers.
The study will examine the quality of two sedation techniques (dexmedetomidine and pentobarbital) used for children aged 3 to 24 months who are undergoing a transthoracic echocardiography (TTE).
