The aim of the study is to facilitate radial artery access for cardiac catheterization. The investigators hypothesize that topical nitroglycerin and lidocaine will reduce radial artery spasm. Patients undergoing cardiac catheterization via the radial artery will be randomized to topical nitroglycerin + lidocaine versus placebo.
The radial artery, which is located on the outer side of the forearm, can be used in interventional procedures, such as cardiac catheterization, to provide access to the arterial blood supply. In order to facilitate successful catheterization of the artery, a dilated artery and one free of arterial spasm is desirable. The proposed study will randomize twenty three healthy subjects to determine the effect of topical nitroglycerin on radial artery vasodilation. In the first phase...
The radial approach for a coronary angiography has became popular in several centers because of its simplicity and fewer complications. The radial artery occlusion (RAO) is the main inconvenient and impose a limitation of future use of the radial artery as an access site for catheterization in the future. Several strategies have been used to decrease the incidence of RAO (heparin, patent hemostasis, etc). Nitrates in intra-arterial have been widely studied in prevention of this...
The purpose of this study is to collect data about the efficacy of utilizing distal topical heat application for dilatation of the radial artery. Transradial arterial access is widely accepted as the standard of care for cardiac catheterization procedures due to its increased patient comfort and significantly decreased risk of major vascular complications, and has been recently utilized in increasing volume by the interventional radiology community throughout the world. Due to ...
This study is being done to determine if lidocaine, administered during surgery and for 24 hours after surgery can reduce inflammation, thereby reducing the risk of atrial fibrillation and delirium after surgery. Participants undergoing cardiac surgery will be randomized to receive either lidocaine or placebo.
The aim of this study is to find out and record the indications for diagnostic catheterization as well as for interventional cardiac catheterization in A.U.C.H , and record the outcome in these cases.
Retinal emboli is a common phenomenon in cardiac catheterization. In this study the investigators evaluate the incidence of retinal emboli post diagnostic and therapeutic cardiac catheterization over 300 patients. The incidence was 6.3% and had no clinical sequel on visual acuity and visual field.
This study is a prospective, randomized study of patients with single ventricle heart disease who are to undergo superior cavo-pulmonary anastomosis, or "Glenn" operation. Such patients have historically undergone cardiac catheterization to ensure suitability for the procedure. Cardiac magnetic resonance imaging (cardiac MRI) is a newer technology that provides excellent anatomic and functional imaging of the heart. This study is designed to demonstrate our hypothesis that card...
Cardiac catheterization has traditionally been performed via access to the arterial circulation from the femoral artery located in the groin. As an alternative to this approach, the radial artery, located in the arm, is gaining wider use in clinical practice. Multiple studies have demonstrated that cardiac catheterization via the radial approach has a very low complication rate, in the short term. This study is intended to determine if there are any differences in the long te...
We will conduct a randomized controlled trial that aims to compare the incidence of contrast-induced nephropathy between transradial- and transfemoral-access cardiac catheterization.
Periprocedural management of guidewire placement and removal in patients needing cardiac catheterization by use of marking of the access site and removal procedure due to a graduated scheme
Patients admitted for acute heart failure and undergoing right heart catheterization will be enrolled in this study. Subjects will undergo catheterization of the heart to obtain central cardiac pressure and other cardiac hemodynamic parameters. Subsequently, the subject will undergo a regional nerve block of the splanchnic nerves. Patients will remain in the catheterization lab for the duration of anesthetic block and will be continuously hemodynamically monitored. This ...
This study is intended to investigate the effect of nitroglycerin on vericiguat in patients with stable coronary artery disease (CAD). Nitroglycerin is the standard therapy to treat acute crisis of angina. Thus there is a high likelihood of co-administration of both drugs in the target indication of vericiguat, worsening heart failure (HF). Therefore, it is important to investigate the safety and tolerability of vericiguat and nitroglycerin, which may be used as unprescribed on...
This study will use contrast echocardiography to assess the accuracy of a new non-invasive imaging method for subharmonic aided pressure estimation (SHAPE) compared to simultaneously acquired intra-cardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with...
The purpose of this research study is to test the safety, tolerability, and effectiveness of Topical AmphiMatrix with Nitroglycerin (MQX0503) to relieve Raynaud's symptoms and increase blood flow to the fingers.
Bleeding complications after cardiac catheterization have been reviewed previously, but there are very few studies on retroperitoneal hematoma and appropriate treatment of patients is not well defined. For this reason, we aimed to analyze the clinical manifestations of retroperitoneal hematomas in a single center using a case-control study design, to analyze the treatment procedure determinants and consequently to provide an updated and usable treatment algorithm.
To determine if survival to hospital discharge with good neurological outcome for adults ages 18-75 who are resuscitated from out-of-hospital VT/VF cardiac arrest without clinical signs of a heart attack do better by going straight to the cardiac catheterization laboratory or admitted to the intensive care unit for evaluation. The investigators think a large portion of resuscitated patients presenting with VT/VF have ischemic heart disease which is the cause for the arrest. And...
When compared to aqueous gel, 2% Lidocaine jelly does not reduce the pain perception during evaluation of postvoid residual volume and the Q-tip test.
The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound technique called subharmonic-aided pressure estimation (SHAPE).This study will use contrast echocardiography to assess the accuracy of SHAPE compared to simultaneously acquired intracardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast ...
The purpose of this study is to see if a drug called lidocaine prevents cognitive injury (a decline in mental abilities) after heart surgery. Lidocaine is currently FDA approved and is commonly used for treating some heart rhythm disorders and for regional anesthesia (blocking nerves). The investigators are enrolling subjects in this research project to see if lidocaine will reduce the high incidence of cognitive injury seen after heart surgery. As part of this study, the inves...
The purpose of this study is to determine if a single application of Lidocaine gel topical anesthesia is as effective in decreasing the discomfort associated with urinary catheterization as two applications, within our pediatric population. Currently, two applications is our standard of care within our pediatric Radiology Department. Urinary catheterization is the process of placing a flexible tube into the urinary opening (urethra), to drain urine or instill radiographic solut...
This work will assess the reliability of a simple painless test for the effectiveness of the commonly used local anesthetic lidocaine
This study evaluate topical anaesthesia application for 30 minutes before tranradial catheterization during cardiac catheterization can reduce pain and decrease radial artery spasm
Patients will be randomized prospectively to one of two groups. One group will receive 5 mg/kg of 1% lidocaine, and the other will receive .9 normal saline, instilled into their VAC sponge ½ hour prior to VAC dressing change. All patients will complete a pain assessment tool prior to receiving the instilled lidocaine/placebo, immediately after the procedure and 1 hour after the procedure. Pain scores will then be compared between the lidocaine and placebo groups. Ris...
The overall goal of this study is to evaluate agreement between cardiac MR parameters and well-established clinical and catheterization parameters of poor prognosis in patients with pulmonary hypertension. The identification of noninvasive cardiac MR techniques to evaluate myocardial disease in patients with pulmonary hypertension would be beneficial to society due to the potential to replace serial invasive cardiac catheterization procedures with a noninvasive imaging test.
