Axillary arteries are less calcified and tortuous than iliofemoral arteries Axillary artery minimal luminal diameters are usually >5.0 mm even in patients with iliofemoral artery diameters < 5.0 mm Axillary and transcaval access are the only non-surgical fully percutaneous options for large-bore arterial access for TAVR or mechanical circulatory support devices.

Aims: To determine the bioequivalence of several T1 mapping sequences in myocardial characterization of diffuse myocardial fibrosis. Methods and results: We performed an intra-individual sequence comparison of three types of T1 mapping sequences [MOdified Look-Locker Inversion recovery (MOLLI), Shortened MOdified Look-Locker Inversion recovery ((sh)MOLLI), and SAturation recovery single-SHot Acquisition (SASHA)]. We employed two model diseases of diffuse interstitial fibrosis [patients with non-ischaemic dilated cardiomyopathy (NIDCM), n = 32] and aortic stenosis [(AS), n = 25)]...

The World Bank is publishing nine volumes of Disease Control Priorities, 3rd edition (DCP3) between 2015 and 2018. Volume 9, Improving Health and Reducing Poverty, summarises the main messages from all the volumes and contains cross-cutting analyses. This Review draws on all nine volumes to convey conclusions. The analysis in DCP3 is built around 21 essential packages that were developed in the nine volumes. Each essential package addresses the concerns of a major professional community (eg, child health or surgery) and contains a mix of intersectoral policies and health-sector interventions...

OBJECTIVE: Evaluation of invasive hemodynamic parameters as prognostic markers of mortality in patients undergoing TAVR. BACKGROUND: The value of invasive intraprocedural hemodynamic evaluation of patients undergoing transcatheter aortic valve replacement is unclear. METHODS: Consecutive patients who underwent transfemoral TAVR and had complete prospectively collected intraprocedural invasive hemodynamic parameters were retrospectively analyzed...

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...

BACKGROUND: Quantification of cardiac output and pulmonary vascular resistance (PVR) are critical components of invasive hemodynamic assessment, and can be measured concurrently with pressures using phase contrast CMR flow during real-time CMR guided cardiac catheterization. METHODS: One hundred two consecutive patients underwent CMR fluoroscopy guided right heart catheterization (RHC) with simultaneous measurement of pressure, cardiac output and pulmonary vascular resistance using CMR flow and the Fick principle for comparison...

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...

OBJECTIVES: To evaluate balloon-expandable and self-expanding third-generation transcatheter aortic valve replacement (TAVR) devices according to patient selection criteria and outcomes. BACKGROUND: Two competing third-generation TAVR technologies are currently commercially available in the US. There are no published head-to-head comparisons of the relative performance of these two devices. METHODS: 257 consecutive patients undergoing TAVR with a third-generation balloon-expandable (Edwards Sapien 3) or self-expanding device (Medtronic CoreValve Evolut R) at a single US medical center were included...

OBJECTIVES: This study sought to use a new catheter technique to split the anterior mitral valve leaflet (AML) and prevent iatrogenic left ventricular outflow tract (LVOT) obstruction immediately before transcatheter mitral valve replacement (TMVR). BACKGROUND: LVOT obstruction is a life-threatening complication of TMVR, caused by septal displacement of the AML. METHODS: The procedure was used in patients with severe mitral valve disease and prohibitive surgical risk...
