BACKGROUND: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. METHODS AND RESULTS: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N=200) and a new image noise reduction fluoroscopy system (N=200)...

Kinking of the catheter due to excessive rotation is not a rare complication. However, percutaneous retrieval of a kinked catheter can be difficult. The key to bailout is fixation of the catheter tip. Herein, we present a 78-year-old woman who had this complication during transradial angiography. Retrieval using several previously reported techniques was unsuccessful. We finally retrieved the kinked catheter by fixing the tip of the catheter, using external and internal compressions. The former comprises manual compression on the axillary artery, while the latter comprises deployment of a balloon catheter via another puncture site...

A 76-year-old man with aplastic anemia presented with recurrent acute myocardial infarction (AMI) with heart failure. After the initial appearance of AMI approximately 2 months earlier, he had received conservative treatment/transfusion alone because of severe thrombocytopenia and anemia (platelet 11 × 10(3)/μL, hemoglobin 6.4 g/dL). Refractory heart failure persisted despite repeated conservative treatment/transfusion for the second AMI, and therefore, we performed transradial coronary angiography and left main crossover stenting with a bare metal stent...

Background and Aim. The aim of study was to evaluate safety, feasibility, and procedural variables of transradial approach compared with transfemoral approach in a standard population of patients undergoing coronary catheterization as one of the major criticisms of the transradial approach is that it takes longer overall procedure and fluoroscopy time, thereby causing more radiation exposure. Method. Between January 2015 and December 2015, a total of 1,997 patients in LPS Institute of Cardiology, GSVM Medical College, Kanpur, UP, India, undergoing coronary catheterization were randomly assigned to the transradial or transfemoral approach...

OBJECTIVE: To compare radiation exposure during transradial diagnostic coronary angiography (DCA) using standard single- or multi-catheters with different shapes. BACKGROUND: Transradial DCA can be performed using single- or multi-catheters to canulate left and right coronary ostia. To date, it remains unknown whether there are differences in radiation exposure between the two strategies. METHODS: From November 2012 to June 2014, 3,410 consecutive patients who underwent transradial DCA were recruited...

We report transradial access (TRA) for emergency carotid artery stenting (CAS) as a useful alternative when the femoral artery cannot be accessed. A 63-year-old man arrived at our emergency room 30 minutes after left hemiplegia and loss of consciousness. Brain computed tomography (CT) anigograpy showed occlusion of the right interntal carotid artery (ICA) and CT perfusion revealed delayed time-to-peak in the territory of the middle cerebral artery. For, endovascular treatment, trans-femoral access (TFA) was attempted but failed due to occlusion of the abdominal aorta...

The volume of cardiac diagnostic procedures involving the use of ionizing radiation has increased rapidly in recent years, and the radiation exposure experienced by patients undergoing any medical imaging procedure has recently obtained a growing attention. Transradial (TR) access is being increasingly used worldwide for diagnostic coronary angiography (CA), and percutaneous coronary interventions, since it offers several benefits as compared to transfemoral (TF) access, such as by reducing hemostasis time and vascular complications, increased patient comfort, reduced hospital stay, and lower cost...

AIMS: During transradial coronary catheterization the radial artery is functionally occluded and hand perfusion depends on the collateral circulation. Nexfin is a simple, non-invasive technique to measure digital arterial pressure and could serve to quantify the palmar collateral circulation. Potentially, inter-individual differences in the extent of collateralization are related to perfusion and function after transradial intervention. METHODS AND RESULTS: In total 85 adults were included (18 healthy volunteers; 67 patients who underwent transradial catheterization)...

BACKGROUND: While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. METHODS: We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters...

BACKGROUND: Radial access is the preferential access route in patients undergoing diagnostic coronary angiography. We hypothesised that we could reduce hospital stay and improve patient comfort by accelerated deflation of the radial compression device (Terumo radial band). AIMS: The aim of this study was to compare accelerated pressure reduction with a standard Terumo radial band protocol with regard to local bleeding complications and reported pain scores after cardiac catheterisation...

Minimizing the catheter size can reduce vascular access complications and contrast dye usage in coronary angiography. The small diameter of the 4Fr guiding catheter has limited the use of several angioplasty devices such as intravascular ultrasound (IVUS) in the past. However, the combination of a novel IVUS catheter and a 0.010 guidewire makes it possible to perform IVUS-guided percutaneous coronary intervention (PCI) with a 4Fr guiding catheter. We herein report the case of a 51-year-old man with silent myocardial ischemia who underwent IVUS-guided transradial PCI with a 4Fr guiding catheter...

BACKGROUND: Transradial catheterisation is known to be associated with occlusion of the radial artery with an estimated incidence of 2-10% (1). There are very few studies looking at the patency of radial artery as a bypass graft after utilisation for catheterisation. METHODS: We conducted a retrospective review of patients undergoing coronary artery bypass grafting (CABG) utilising a radial artery graft. RESULTS: Long term patency rates were 59% in radial artery grafts utilised for catheterisation prior to CABG, compared to 78% if it were not (p= 0...

The percutaneous transradial approach for coronary angiography and percutaneous coronary intervention is increasing in the United States. Although its vascular safety profile is better than the traditional femoral approach, it is important to learn about potential complications. In this article, we present two cases of vascular complications, namely, pseudoaneurysm and radial artery occlusion, after transradial cardiac catheterization, along with a review of the relevant literature.

BACKGROUND: The transradial approach has become the preferred vascular access during conventional coronary angiography (CCA). Hereby, we evaluated the impact of pre-procedural radial artery diameter (RAD), the cross-sectional area (CSA), and the perimeter on vascular complications (VACs). METHODS: We conducted a single-center prospective analysis of 513 patients who underwent CCA. Radial artery ultrasonography was performed before and after CCA to measure the RAD, CSA, and perimeter...
