EDITORIAL
Toby Rogers, Lowell F Satler
A novel device that diverts a proportion of contrast injected by hand through the manifold can potentially reduce volume of contrast delivered to the patient by almost 50% to reduce risk of contrast-induced nephropathy. Another simple solution to reducing contrast volume is to limit the number of angiographic views and cine runs acquired. A conscious effort by the angiographer to limit the contrast volume to less than the eGFR should be considered.

REVIEW
Toby D Rogers, Giulia Cambiè, Michel J Kaiser
The lack of detailed life history (LH) information (e.g. age, growth, size at maturity, sex composition etc.) for many species of conservation importance limits the implementation of appropriate conservation measures. Typically, LH information is acquired using lethal sampling techniques, which undermines the goal of conservation. This is particularly problematic for many shark species that have low fecundity and slow growth rates. Here we tested the use of non-invasive laser photogrammetry to measure body morphometry in vivo...

OBJECTIVES: Electrifying a coronary guidewire may be a simple escalation strategy when trans-septal needle puncture is unsuccessful. BACKGROUND: Radiofrequency energy to facilitate trans-septal puncture through a dedicated device is costly and directly through a trans-septal needle may be less safe. Our technique overcomes these limitations. METHODS: The technique was used in patients when trans-septal needle penetration failed despite excessive force or tenting of the atrial septum...

BACKGROUND: Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety...

Patients at high bleeding risk (HBR) are at increased risk of bleeding following percutaneous coronary intervention (PCI) with drug-eluting stents (DES) due to the need for longer dual antiplatelet duration. We sought to evaluate the likelihood of receiving DES during PCI in HBR populations and to characterize DES utilization trends over time. Consecutive patients who underwent PCI from April 2003 to September 2015 were identified. HBR is defined as patients fulfilling 1 or more of the HBR criteria: age ≥75 years, anticoagulation use at discharge, history of stroke, cancer in previous 3 years, glucocorticoid use, hemoglobin (Hgb) <11 g/dl, platelet count <100,000/mm(3), or creatinine clearance (CCr) <40 ml/min...

In X-ray fluoroscopy, static overlays are used to visualize soft tissue. We propose a system for cardiac and respiratory motion compensation of these overlays. It consists of a 3-D motion model created from real-time MR imaging. Multiple sagittal slices are acquired and retrospectively stacked to consistent 3-D volumes. Slice stacking considers cardiac information derived from the ECG and respiratory information extracted from the images. Additionally, temporal smoothness of the stacking is enhanced. Motion is estimated from the MR volumes using deformable 3-D/3-D registration...

The Valve Academic Research Consortium-2 recommends cutoff levels of cardiac troponin of >15 and of creatine kinase MB (CKMB) of >5 of the upper limit of normal (ULN) as markers of periprocedural myocardial infarction. We aimed to evaluate the correlation of these cutoffs with the survival rate in patients who underwent transcatheter aortic valve implantation (TAVI) through the femoral access. Patients who underwent TAVI were classified according to the postprocedural peak marker level of >15 and >5 ULN for troponin and CKMB, respectively...

We aimed to evaluate the success rates of balloon valvuloplasty post-dilation (BVPD) and a second-valve deployment in reducing residual aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) and its impact on outcome. Residual AR immediately post-TAVI in patients with aortic stenosis is a common condition that adversely affects outcome. Patients who underwent TAVI who had more-than-mild residual AR were managed either with medical therapy, re-intervention with BVPD, or a second valve...

Transradial percutaneous coronary intervention (TR-PCI) may be associated with reduced rates of acute kidney injury (AKI). There is limited data from real-world registries about AKI rates stratified by PCI access. Our aim was to evaluate AKI rates and correlates in TR-PCI versus transfemoral PCI (TF-PCI) in a propensity score-matched analysis of patient data from a large, single-center registry. We performed a 1:1 propensity score-matched analysis on consecutive patients who underwent PCI from January 2011 to June 2016, excluding those on dialysis...

BACKGROUND: Deep neck flexor (DNF) muscles stabilize the neck and contribute to head acceleration control. The function of DNF in cervical spine dynamic stabilization has not been examined in athletes of any age group, including adolescents. This investigation was necessary prior to studying the DNF muscles' role in cervical spine injury patterns. OBJECTIVES: The objectives of this study were (1) to determine average Deep Neck Flexor Endurance Test (DNFET) time scores in high school-aged and university-aged subjects (aged 14-22 years); and (2) to establish the relationship between gender and age for adolescent DNFET time scores...

We sought to determine whether balloon-expandable valve (BEV) and self-expanding valve (SEV) affect valve hemodynamics differently according to native aortic annulus size. Transcatheter aortic valve replacement can achieve superior prosthetic valve hemodynamics compared with surgical aortic valve replacement, particularly in patients with small aortic annulus. One hundred ninety-three consecutive transcatheter aortic valve replacement patients were grouped into tertiles defined by computed tomography derived aortic annulus systolic perimeter...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...
