OBJECTIVES: The goal of this study is to evaluate the safety and efficacy of the second-generation robotic-assisted system CorPath GRX (Corindus) for percutaneous coronary intervention (PCI). BACKGROUND: The first-generation CorPath 200 robotic-assisted system for PCI is effective, but is limited by the lack of an active robotic guide-catheter control. The CorPath GRX device enables robotic guide-catheter manipulation, in addition to guidewire and balloon/stent delivery...

INTRODUCTION: To evaluate the flow characteristics produced by a manual and automated-pump irrigation system connected to a flexible ureteroscope. METHODS: An in vitro analysis of a manual hand-pump infuser (HP) and the UROMAT Endoscopic Automatic System for Irrigation® (E.A.S.I.) pump was performed. Standard irrigation tubing was used to connect a three-way valve to a flexible ureteroscope, the irrigation system and a digital manometer. Flow rate and irrigation pressure measurements were recorded over a 15-minute period using pressure settings of 150 and 200 mmHg for both irrigation pump systems...

OBJECTIVES: To identify potential underlying mechanisms of early and (very) late scaffold thrombosis (ScT) by optical coherence tomography (OCT), in a frame-by-frame analysis. BACKGROUND: The absorb scaffold is associated with an increased risk of ScT compared with metallic stents. Several potential causes of bioresorbable ScT have been identified, however the precise etiology still remains unclear. METHODS: Between February 2013 and February 2016, 13 patients presenting with definite ScT underwent OCT imaging...

BACKGROUND: The aim of this study was to develop a minimal invasive complete spinal cord injury (SCI) minipig model for future research applications. The minipig is considered a translationally relevant model for SCI research. However, a standardized minimal invasive complete SCI model for pigs has not yet been established. METHODS: Adult Göttingen minipigs were anesthetized and placed in extended prone position. After initial computed tomography (CT) scan, the skin was incised, a needle placed in the epidural fatty tissue...

Purpose: A prototype steerable catheter was designed for endovascular procedures. This technical pilot study reports the initial experience using the catheter for cannulation of visceral arteries. Technique: The 7F catheter was manually steerable with operator control handle for bending and rotation of the tip. The maximum bending angle was approximately 90° and full 360° rotation of the tip was supported. The study involved 1 pig with 4 designated target arteries: the left and right renal arteries, the superior mesenteric artery, and the celiac trunk...

OBJECTIVE: Nephrostomy tubes (NT) inserted in emergency settings by interventional radiologists are frequently unsuitable for subsequent percutaneous nephrolithotomy (PCNL). We report a novel method of adjusting these NTs to be used as PCNL tracts and avoid renal re-puncture. PATIENTS AND METHODS: A retrospective search of 981 consecutive PCNLs performed in our institution between 2002-2017 identified all patients with preoperatively inserted NTs. The NTs unsuitable for PCNL were adjusted by a novel approach in which a 5-mm incision was made at the ideal puncture location (IPL) as indicated under fluoroscopic guidance...

INTRODUCTION: Cerebral-protection devices (CPDs) are a well-established system for reduction of embolic risk in carotid artery angioplasty and stenting (CAS). Although rare, adverse events with CPDs are unpredictable and can be associated with serious outcomes and iatrogenic sequelae. PRESENTATION OF CASE: We describe the unique case of dislocation of a FilterWire EX™ filter loop during right CAS. On trying to recapture the CPD filter at the end of the procedure, the filter loop suddenly detached from the guidewire and dislocated to the proximal middle cerebral artery...

BACKGROUND & AIMS: Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP). Pancreatic duct guidewire placement method (PGW) is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP). The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts...

BACKGROUND AND AIMS: Wire-guided biliary cannulation has been demonstrated to improve cannulation rates and reduce post-ERCP pancreatitis (PEP), but the impact of wire caliber has not been studied. This study compares successful cannulation rates and ERCP adverse events using a 0.025-inch and 0.035-inch guidewire. METHODS: A randomized, single blinded, prospective multi-center trial at 9 high volume tertiary referral centers in the Asia Pacific region was performed...

OBJECTIVES: To describe and evaluate the efficacy of a novel antegrade dissection/re-entry (ADR) technique, called antegrade fenestration and re-entry (AFR), for chronic total occlusions (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The widespread adoption of ADR is limited by several technical, logistic, and financial factors. Therefore, novel ADR techniques are needed. METHODS: AFR consists in creating multiple fenestrations of the dissection flap separating the false and true lumen...

BACKGROUND: Proper vessel sizing during endovascular interventions is crucial to avoid adverse procedural and clinical outcomes. LumenRECON (LR) is a novel, nonimaging, 0.035-inch wire-based technology that uses the physics-based principle of Ohm's law to provide a simple, real-time luminal size while also providing a platform for therapy delivery. This study evaluated the accuracy, reliability, and safety of the LR system in patients presenting for a femoropopliteal artery intervention...

AIM: The balloon assisted tracking (BAT) technique is utilised to overcome various anatomical difficulties during radial procedures when standard measures such as adequate sedation, pain relief, vasodilators and use of hydrophilic guidewires, fail. The aim of this study was to evaluate the success rates of the BAT technique in overcoming anatomical difficulties during radial coronary interventional procedures. METHODS: We retrospectively reviewed 1100 consecutive patients undergoing coronary procedures from the transradial approach (TRA) between May 2015 and May 2017...

Peter Tajti, Yader Sandoval, Emmanouil S Brilakis
For patients with prior coronary artery bypass graft surgery, reaching lesions in native coronary arteries distal to the anastomosis of bypass grafts can be challenging due to long distance between the graft ostium and the lesion and significant tortuosity that needs to be traversed. We describe one such lesion in a patient presenting with non-ST segment elevation myocardial infarction and cardiogenic shock. The lesion was successfully treated using a variety of strategies, including use of a short guide catheter, long guidewire, a guide catheter extension, long shaft balloons and stents, and short length stents...

OBJECTIVE: To describe our ultrasound technique for confirming intraoperative, antegrade-placed ureteral stent position during laparoscopic pyeloplasty. BACKGROUND: Disadvantages of retrograde stent placement include the need to reposition the patient into and out of the lithotomy position. Antegrade stent placement can reduce procedure time but requires confirming appropriate distal placement into the bladder with cystoscopy, percutaneous drain placement, or instillation of methylthioninium chloride or indigo carmine...

Introduction Arterioureteral fistula (AUF) is a rare but potentially life-threatening disease which primarily arises as a long-term complication in oncological patients who have permanent ureteric stenting. The incidence is rising. The objective of this study was to outline the risk factors for, management and outcome of AUF in a large individual case series. Patients and methods 26 AUF cases in 24 patients from six German tertiary referral centres occurring between 2008 and 2016 were identified retrospectively and entered into a dedicated database using patient notes and out-patient visits...

BACKGROUND: Cannulation of the great vessels is required for extracorporeal membrane oxygenation (ECMO). Currently, there is no guideline for optimal imaging modalities during percutaneous cannulation of ECMO. OBJECTIVE: The purpose of this study was to describe percutaneous cannulation guided by point-of-care ultrasound (POCUS) for ECMO and compare it with fluoroscopy and landmark guidance. METHODS: Three groups (POCUS-, fluoroscopy-, and landmark-guided) of percutaneous cannulation for ECMO were analyzed retrospectively in a tertiary academic hospital...
