Percutaneous coronary intervention is commonly used to treat coronary artery disease. Both transradial and transfemoral approaches are applied. In general, fewer complications are seen with the transradial approach compared to the transfemoral access, for which reason the transradial catheterization is frequently preferred. In this case presentation, we describe 2 cases of elective transradial coronary angiography both resulting in severe central vascular complications: perforation of the right subclavian artery with a mediastinal hematoma and dissection of the brachio-cephalic trunk and the aortic arch...

BACKGROUND: It remains unclear whether radial access (RA), compared with femoral access (FA), mitigates the risk of acute kidney injury (AKI). OBJECTIVES: The authors assessed the incidence of AKI in patients with acute coronary syndrome (ACS) enrolled in the MATRIX-Access (Minimizing Adverse Haemorrhagic Events by Transradial Access Site and Systemic Implementation of Angiox) trial. METHODS: Among 8,404 patients, 194 (2.3%) were excluded due to missing creatinine values, no or an incomplete coronary angiogram, or previous dialysis...

OBJECTIVES: The aim of this study was to compare bivalirudin with heparin as anticoagulant agents in patients with ST-segment elevation myocardial infarction treated with radial primary percutaneous coronary intervention (PCI). BACKGROUND: Recent studies in which PCI was performed predominantly via radial access did not show bivalirudin to be superior to heparin. METHODS: Outcomes were compared in patients with STEMI included in the National Cardiovascular Data Registry CathPCI database from 2009 to 2015 who underwent primary PCI via radial access and who were anticoagulated with bivalirudin or heparin...

Previous studies have showed that arm position variations would significantly degrade the classification performance of myoelectric pattern-recognition-based prosthetic control, and the cascade classifier (CC) and multiposition classifier (MPC) have been proposed to minimize such degradation in offline scenarios. However, it remains unknown whether these proposed approaches could also perform well in the clinical use of a multifunctional prosthesis control. In this study, the online effect of arm position variation on motion identification was evaluated by using a motion-test environment (MTE) developed to mimic the real-time control of myoelectric prostheses...

During transradial intervention, sharp edge of the guide catheter tip may act like a "razor-blade" and can prevent the catheter navigation especially in situation like double hair pin loop. Here, we report primary percutaneous coronary intervention (PCI) through diagnostic catheter using an innovative technique, balloon-assisted sliding and tracking (BLAST), to overcome this double hairpin loop, thus saving time and contrast volume.

AIMS: To demonstrate the feasibility of distal left transradial approach for patients in whom left radial access is preferred over right radial access for coronary angiography and interventions. This procedure is more convenient for the operator. For the right- handed patient, left radial access is more convenient because of the free use of the right hand after the procedure. In addition, this technique reduces the chance for radial artery occlusion at the site of the distal forearm. METHODS AND RESULTS: Coronary access via the left distal radial artery at the anatomical snuffbox allows comfortable positioning of the dorsal side of the patient's left hand near the right groin...

To investigate the postprocedural cardiovascular events and vascular outcomes, including hand ischemia and neurological compromise, after transulnar (TU) catheterization in ipsilateral radial artery occlusion.Previous randomized trials have shown that the transulnar (TU) approach for coronary angiogram and intervention has safety and outcomes similar to those of the transradial (TR) approach. However, the safety of the TU procedure when ipsilateral radial artery occlusion occurs is unknown.We retrospectively reviewed 87 TU cases with ipsilateral radial artery occlusion confirmed by a forearm angiogram...

The prevalence of radial access for transradial catheterization remains low in the United States, occurring in only 28% of cases in the National Cardiovascular Data Registry (NCDR) CathPCI. It is unknown whether the low adoption rate has been influenced by patient characteristics or is more operator dependent. In a 10-center study, we compared clinical and demographic characteristics among 323 radial and 1,506 femoral access percutaneous coronary intervention (PCIs) performed by 65 interventionists capable of radial PCI...

Vascular access sheaths are now available with thin walls specifically designed for transradial use. A thin-walled sheath with an outside diameter on the same order of size as a 6-F traditional sheath can carry a 7-F guiding catheter. While the larger-sized guides may increase the interventional options for the radial operator, a hazard from vascular damage due to the larger-sized lumens may exist and points to a need for further improvement in radial specific equipment.

Transradial access (TRA) is often avoided in favor of the transfemoral access (TFA) during percutaneous coronary interventions of the unprotected left main coronary artery (ULM), due to technical and safety concerns. The aim of this study was to compare the performance of TRA and TFA in the treatment of ULM with second-generation drug-eluting stents. Consecutive patients who underwent percutaneous coronary intervention on ULM with second-generation drug-eluting stents were retrospectively enrolled in the multicenter Failure in Left Main Study With 2nd Generation Stents (FAILS 2) registry...

We report a new technique of arterial access through the ipsilateral interosseous artery in a case of late radial artery occlusion (RAO). RAO, although not frequent, is a limiting iatrogenic complication after transradial intervention (TRI) and precludes repeat use of the same radial artery for future procedures. Our technique involves obtaining access to the ipsilateral radial artery (RA) in the distal postocclusion segment and use of collateral channel between this segment and the interosseous artery (IOA) for advancing a guidewire and sheath in the IOA lumen and in brachial artery thereafter...

BACKGROUND: Transradial approach has significantly decreased the rate of access site bleeding in patients undergoing percutaneous coronary interventions (PCI), therefore potentially mitigating the benefits offered by bivalirudin in lowering major bleeding complications as compared to heparin. However, nonaccess site bleeding, that represent the majority of hemorrhagic complications, still carry negative prognostic consequences for these patients and no study has so far defined the exact impact of bivalirudin on nonaccess site bleeding, that was therefore the aim of present meta-analysis...

OBJECTIVES: To explore patient preference for vascular access site in percutaneous coronary procedures, the perceived importance of benefits and risks of transradial access (TRA) and transfemoral access (TFA) were assessed. In addition, direct preference for vascular access and preference for shared decision making (SDM) were evaluated. BACKGROUND: TRA has gained significant ground on TFA during the last decades. Surveys on patient preference have mostly been performed in dedicated TRA trials...

OBJECTIVES: to understand the role of a transradial (TR) secondary approach during complex percutaneous interventions. BACKGROUND: The value of the TR route for ancillary vascular approach has not been adequately validated in this setting, and there is scant data on its role in reducing bleeding complications. METHODS: In the present study we retrospectively included patients undergoing the following interventions requiring two vascular approaches at nine high-volume centers in Italy: structural cardiac interventions, complex PCI, endovascular aortic repair (EVAR) and complex lower limb angioplasty...

BACKGROUND: Radiation exposure is an important issue for interventional cardiologists that is often underevaluated. Our aim was to evaluate determinants of operator radiation exposure during percutaneous coronary procedures. METHODS: The RADIANT (NCT01974453) is a prospective, single-center observational study involving 4 expert operators and 2 fellows performing percutaneous coronary procedures. The operator radiation dose was evaluated using dedicated electronic dosimeters in 2,028 procedures: 1,897 transradial access (TRA; 1,120 right and 777 left TRA) and 131 transfemoral access (TFA)...
