Filter by:The distal transradial approach (dTRA) via the anatomical snuffbox is hypothesized to be more beneficial than the conventional transradial access (cTRA) in patients undergoing coronary procedures. This prospective single-center randomized trial was designed to investigate the safety, efficacy, and various ultrasound parameters of dTRA.
This research; The aim of this study was to evaluate the effect of the pre-procedural education given to the patients undergoing coronary angiography on the anxiety level and vital signs of the patients.
As a multi-center, retrospective observation study in southern China, this study included the main study population of patients who underwent coronary angiography at 5 hospitals from Guangzhou, Shenzhen, Yangjiang, Maoming and Longyan from January 2000 to Decemeber 2020. The hospitalization information was collected in the form of direct derivation of the case, and cardiac and renal adverse events were collected through outpatient system. Data on all-cause death were obtained from the Guangdong Provincial Public Security and matched to the electronic Clinical Management System of the Guangdong Provincial People's Hospital records.
Transradial approach has become the default arterial access for coronary angiography (CAG) and percutaneous coronary intervention (PCI), mainly due to lower incidence of bleeding compared to transfemoral access.1 However, TRA is not deprived of local access site complications such as radial artery occlusion (RAO), occurring in approximately 5.2% of patients, compartment syndrome, pseudoaneurysm, hematoma, and arteriovenous fistula. Recently, a novel approach has been proposed, the access through the distal radial artery (distal transradial access, dTRA), located in the anatomical snuffbox. Initial studies regarding the dRA have shown feasibility and benefits, including shorter hemostasis time, fewer local access site complications and potentially lower incidence of RAO. GlideSheath Slender is a novel sheath which has a hydrophilic coating and is made of a thinner material than traditional sheaths. As a result, the external diameter of the 5 Fr GlideSheath Slender sheath is 1 Fr lower compared with conventional arterial sheaths. The purpose of the present study was to investigate whether the use of the Slender sheath affects the time of hemostasis, sheath insertion time, crossover rate to conventional radial access, pain associated with the procedure and incidence of local access site complications (RAO, distal radial artery occlusion, fistula, hematoma) in patients undergoing diagnostic angiography through the distal radial artery.
Prospective randomized non-blinded study to determine degree of vessel trauma and adverse remodeling of the proximal forearm radial artery following distal radial artery access (dTRA) for cardiac catheterization compared to standard forearm transradial access (fTRA).
All patients in Iceland with STEMI (2008-2018) and NSTEMI (2013-2018) that underwent coronary angiography and had obstructive coronary artery disease were included. Information about patients and angiography results and treatment were obtained from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR). Survival was estimated with Kaplan-Meier method. Cox regression analysis were used to identify significant risk factors for long-term mortality. Relative survival was defined as observed survival divided by expected survival of the population of Iceland
As a single center, retrospective observation study in Guangdong Institute of Cardiovascular Diseases, this study included the main study population of patients who underwent coronary angiography and / or coronary intervention from January 2007 to Decemeber 2018. The hospitalization information was collected in the form of direct derivation of the case, and cardiac and renal adverse events were collected through outpatient recorder system. All-cause death information was obtained from the Public Security and matched to the electronic Clinical Management System of the Guangdong Provincial People's Hospital records.
This study is designed to compare the bioavailability of the test Product(CE-Iohexol Injection) and the reference product Iohexol Injection (Omnipaque™) following intravenous injection in normal healthy volunteers. The secondary objective is to assess the safety and tolerability of the treatments administered. Captisol® is present to improve stability and to potentially reduce the risk of contrast-induced acute kidney injury(CI-AKI) associated with iohexol administration.
The study team aims to perform a prospective observational case series of one hundred consecutive distal radial artery heart catheterizations to evaluate the safety and feasibility of distal radial access. Distal radial artery access has evolved in the past few years as an alternative to the standard radial artery access for coronary angiography and interventions. However, the available data on the distal radial artery access for coronary angiography and interventions is limited to case reports and small retrospective case series. To date, no prospective randomized data is available. Therefore, the investigators aim to perform a prospective observational case series of one hundred sequential left heart catheterizations performed via distal radial artery to evaluate the safety and feasibility of the distal radial artery access.
The use of coronary intervention has increased over the last decade. Contrast induced nephropathy (CIN) that develops as a result of procedures using intravenous or intra arterial contrast enhancement, or other diagnostic procedures, has been reported to be the third leading cause of acute renal failure in hospitalized patients. It has been hypothesized that this occurs as a result of direct toxicity, oxidative stress, and ischemic injury. Numerous studies have evaluated the incidence of CIN in patients undergoing angiography. There are limited studies in the acute care setting. Therefore, a tool that could identify early risk factors for CIN would be valuable for patient care. Metabolomic profiling is the identification of small molecule metabolites that are altered in response to injury. We hypothetize that urine metabolomic profiles may differ in patients before and after contrast administration coronary intervention.We hypothesized that metabolomic profiles will differ between those patients who develop CIN and those who do not after contrast administration. In addition we believe that metabolomics profiles prior to angiography may identify subjects who will go on to develop CIN and are therefore at higher risk.
