Filter by:This study hypothesizes that Sugammadex may has more appropriate recovery profile than neostigmine in pediatric cardiac patients undergoing cardiac catheterization. In pediatric cardiac patients, clear and rapid recovery (fast-tracking) is required to maintain hemodynamic within the normal physiological values which may be saved by sugammadex
Traditionally, patients are asked to fast prior to invasive cardiac procedures. There exists neither clear evidence nor guidance about the benefits of this. Hypothesis/Objective : To show that allowing unrestricted oral intake before a coronary interventional procedure is not inferior to imposing a pre-procedural fasting period, in terms of adverse events, in patients requiring coronary angiography or a planned or semi-urgent percutaneous coronary intervention. Method: The study is a prospective, monocentric, controlled, single-blind, randomized trial in two parallel arms. The investigating physician performing the interventional procedure and evaluating the safety judgment criteria will not be informed of the patient's randomization arm. In order to keep the blind, the medical and paramedical staff of the interventional cardiology room will not inquire about the fasting status of patients included in the study. Patients are randomized either to the pre-procedural fasting arm or to the absence of pre-procedural fasting. - No intervention: Pre-procedural fasting is defined by the absence of ingestion of fluids or solid food for at least 6 hours before the examination. - Experimental: free feeding and drinking until the procedure. Patients are followed for 4 hours after the end of the procedure at the hospital for adverse events (vagal discomfort, nausea, vomiting or hypoglycaemia). Then a follow-up will be done at day 7 after the procedure (by telephone for outpatients or discharged from the hospital and in the cardiology department for patients still hospitalized on D7) to look for the occurrence of acute renal failure or pneumonia
The purpose of the study is to compare different short durations of radial clamp application following an angiogram via a trans-radial approach.
The current practice of fasting before cardiac catheterization is not based on any studies. If the procedure is to be delayed ( which is common due to busy catheterization lab), this could result in patient's dis-satisfaction and hypoglycemia. Occasionally, cancellation occur because patients are found to be non fasting ( not following the current protocol). The old data of fasting was extrapolated from procedure done under general anesthesia. Now days, cardiac catheterization is always done under local anesthesia and mild sedation. As a matter of fact, emergency cardiac catheterization done for heart attack patients carries more risk than elective one , and are still done without fasting with no reported complication rate like lung aspiration . The highest level of evidence to change the current practice comes from randomized control study. This study has been designed to challenge the current practice. The patients will be divided into 2 groups: - Fasting group (current practice): Clear fluids up to the time of the procedure and no food for at least 2 hours before the procedure. - Non Fasting Group: clear fluids and food and up to the time of the procedure The investigators' aim is to show that there is no difference with regards to potential complications between fasting (current practice) and non fasting (new practice) groups of patients with less incidence of hypoglycemia and hypotension in non fasting group. In addition, The investigators believe that patient satisfaction will be improved if patients are allowed to eat freely before the procedure and the catheter lab working ability will be maximized as the list can be filled promptly with patient on the waiting list (as fasting is no longer required) if a previously booked patient has to be cancelled in the last minute improving patient experience along with the associated financial benefits.
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 sufficient accuracy to allow clinical applicability in humans.
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 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 sufficient accuracy to allow clinical applicability in humans.
Design: Observational - Cross study with followed up for 30 days. The Primary Objective is to realize a record that reflects a national overview of the role of cardiac catheterization in patients with congenital heart disease in hospitals distributed by geographic density of each region of Brazil.
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.
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.
This study is being done to determine if a picture taking test of the heart, positron emission tomography/computed tomography (or cardiac PET/CT), can identify the blockages in the heart arteries that lead to heart attacks when compared to the standard of heart catheterization.
