BACKGROUND: Transradial access (TRA) in percutaneous coronary intervention (PCI) is a widely used standard technique with lower complication rates compared to transfemoral access (TFA). The aim of this study was to evaluate the impact of TRA versus TFA for PCI on clinically significant vascular access complications in the setting of acute myocardial infarction (AMI). METHODS: This multicenter study randomly assigned 250 patients in a 1:1 fashion (TRA vs. TFA) admitted with or without ST-segment elevation AMI undergoing immediate PCI...

We evaluated the efficacy and safety of the fixed dose of 5000 IU unfractionated heparin (UFH) represented as peak activated clotting time (ACT) according to the body mass index (BMI) tertiles in patients undergoing diagnostic transradial coronary angiography (TRCA). A total of 422 patients were included in the present study, 84 in the normal weight group, 218 in the overweight group, and the 120 in the grades 1 and 2 obesity groups. Radial artery occlusion (RAO) was observed in 29 (6.8%) patients and the hematoma was observed in 43 (10...

BACKGROUND: Unfractionated heparin (UFH) is purported to reduce the risk of radial artery occlusion (RAO) after transradial cardiac catheterization. However, the efficacy and optimal dose remain unclear. This meta-analysis evaluates the safety and efficacy of UFH in this context. METHODS: MEDLINE, EMBASE, ISI Web of Science, and the Cochrane Registry were searched from 1948-May 2017. Studies investigating UFH for reducing RAO in transradial coronary catheterization were included...

Transradial approach (TRA) is the default access site for diagnostic angiography and intervention in many centers. Repeat ipsilateral radial artery access late after index procedure has been associated with failures. It is unknown whether early (≤30 days) and very early (<24 hours) repeat radial access is technically feasible and safe. Study population consisted of consecutive patients undergoing repeat (≥2) procedures within 30 days in a high-volume TRA center. Transradial access failure and resulting femoral approach was categorized as primary (no repeat attempt) or secondary (crossover)...

Background/Aims: Transradial intervention (TRI) is becoming the preferred method over transfemoral intervention (TFI) because TRI is associated with lower incidence of major bleeding and vascular complications. However, there has been limited published data regarding the clinical outcomes of TRI versus TFI in Korean patients with ST-elevation myocardial infarction (STEMI). Methods: A total of 689 consecutive STEMI patients who underwent primary percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) from January to December of 2009 at nine university hospitals were enrolled in this study...

Transradial access for coronary angiography and intervention is preferred over the femoral approach but can be technically challenging. Identification of predictors of transradial access failure is important, especially in the context of acute coronary syndromes. We therefore retrospectively analyzed 13,095 consecutive patients (66 ± 12 years, 64% male) in whom transradial access was attempted for coronary angiography or intervention to identify predictors of transradial access failure. Angiograms and patient files were systematically reviewed to analyze patient characteristics associated with failure...

Large pectoral haematoma is an extremely rare complication of transradial catheterisation. Branch or main vessel injury due to luminal passage of guidewires and catheters may lead to bleeding and haematoma formation at adjacent sites along the vessel track. We present a 53-year-old post-transradial catheterisation patient, who complained of chest pain due to right axillary artery branch perforation causing haematoma, which was emergently managed by embolisation with autologous coagulated blood.

BACKGROUND: Following cardiac catheterization using radial artery (RA) access, persistent endothelial dysfunction may limit the use of RA as a conduit during coronary artery bypass graft (CABG) surgery. We reviewed published literature to investigate the effects of transradial coronary catheterization on RA endothelial function. METHODS: We searched PubMed from inception to April 2017 for published studies assessing RA endothelial function late (≥1 month) after coronary catheterization...

INTRODUCTION: Removal of embolization coils eroded into the renal collecting system poses a risk of hemorrhage, which may need to be addressed with arteriography and embolization at the time of treatment. The purpose of this report is to describe a novel approach by which prone percutaneous nephroscopic coil retrieval is coupled with simultaneous prone transradial renal arterial access to mitigate this potential complication. METHODS: A retrospective chart review of the electronic medical record systems was performed from January 2008 to May 2017 to identify patients who had undergone percutaneous removal of embolization coils eroded into the renal collecting system...

Transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. Radial artery pseudoaneurysms present as a rare complication of transradial catheterization. Although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the TR Band(®) (Terumo Medical Corporation, Somerset, NJ) is a novel efficient technique only suggested by a few reports. We describe a 34-year-old man, who underwent transradial primary coronary angiography due to ST-elevation myocardial infarction...

In this paper we introduce a robust multi-channel wearable sensor system for capturing user intent to control robotic hands. The interface is based on a fusion of inertial measurement and mechanomyography (MMG), which measures the vibrations of muscle fibres during motion. MMG is immune to issues such as sweat, skin impedance, and the need for a reference signal that is common to electromyography (EMG). The main contributions of this work are: 1) the hardware design of a fused inertial and MMG measurement system that can be worn on the arm, 2) a unified algorithm for detection, segmentation, and classification of muscle movement corresponding to hand gestures, and 3) experiments demonstrating the real-time control of a commercial prosthetic hand (Bebionic Version 2)...

BACKGROUND: Hemostasis following transradial access (TRA) is usually achieved by mechanical compression. We investigated use of the QuikClot Radial hemostasis pad (Z-Medica) compared with the TR Band (Terumo Medical) to shorten hemostasis after TRA. METHODS: Thirty patients undergoing TRA coronary angiography and/or percutaneous coronary intervention were randomized into three cohorts post TRA: 10 patients received mechanical compression with the TR Band, 10 patients received 30 min of compression with the QuikClot Radial pad, and 10 patients received 60 min of compression with the QuikClot Radial pad...

This retrospective study compares the performance of transradial diagnostic procedures using the single versus Judkins catheter approach. The Judkins approach had a 15% lower patient radiation exposure than single catheter approach while fluoroscopy time was comparable. Future studies of comparing such techniques may always be limited by operator preference, experience, and comfort.
