Filter by:The present study relates to a new approach to coronary artery and coronary artery by-pass graft imaging, and more particularly to computed tomographic angiography following an aortic root injection of a low amount of contrast (up to 30 cc) via a percutaneously placed catheter (Vanguard DX, Medrad Inc.) positioned in the aortic root. The objective of the study is to show the feasibility of Coronary artery CTA using aortic root injection of contrast compared to the standard invasive cardiac catheterization.
The study is to evaluate and compare the effects on kidney function of three iodinated contrast media (CM) in patients at risk of kidney damage evaluating serum creatinine (Scr) concentrations up to three days after CM administration.
The purpose of the present prospective, randomized study is to investigate the clinical effectiveness of standardized left ventricular reconstruction surgery (LVR). In order to standardize the procedure, the operation will be performed with the Blue Egg, manufactured by BioVentrix, a subsidiary of CHF Technologies, Inc.
RIAPRE is a non-interventional registry to be settled in Italy with the purpose of collecting data on 600 cases of high risk elective percutaneous coronary intervention (PCI) patients treated with an anticoagulation regime different from unfractionated heparin in monotherapy. About thirty catheterization laboratories will co-operate in this activity. The long term outcome of patients will be taken into consideration. The availability of these data will allow for a better understanding of the therapeutic needs in this area.
Until today it was not possible to reliably assess the function of a new bypass, i.e., to measure myocardial perfusion. Measuring intramyocardial blood flow directly after revascularisation would greatly improve the assessment of graft function. With transthoracic contrast echocardiography, myocardial perfusion can be reliably assessed, as it has been shown in numerous studies. In the first part of the study the investigators will clarify methodological aspects of contrast echocardiography. In the second part they will analyze the validity of contrast TEE in the operating room.
To assess the procedural success, performance, 30-day and 6 month clinical outcome of bifurcation stenting, and the six month incidence of clinically indicated target lesion revascularization with the use of the Abbott Vascular MULTI-LINK FRONTIER Coronary Bifurcation Stent System in patients with de novo or restenotic bifurcation lesions.
A single post-hospital discharge home visit by a geriatric nurse practitioner or geriatric fellow can bridge the gap and ease the transition for elderly frail patients returning home after hospital admission. We believe this intervention will reduce medication errors, ensure follow-up discharge plans, decrease re-hospitalization rates, and decrease morbidity and mortality.
The purpose of this research study is to obtain experience in the use of fondaparinux (Arixtra) as compared to heparin when administered to patients who undergo percutaneous coronary intervention (PCI). PCI is a mechanical procedure used to widen the narrowing in a coronary artery in patients with symptomatic coronary artery disease. Fondaparinux and heparin are drugs that inhibit blood clotting.
To assess changes in coronary calcium measured by electron beam computed tomography (EBCT) as a predictor of coronary heart disease (CHD) events.
To determine the effects of high or low intensity long-term exercise conditioning in patients with coronary artery disease.
