AIMS: We aimed to investigate the performance of virtual functional assessment of coronary stenoses using intravascular ultrasound (IVUS)-based three-dimensional (3D) coronary artery reconstruction against the invasively measured fractional flow reserve (FFR). METHODS AND RESULTS: Twenty-two patients with either typical symptoms of stable angina or a positive stress test, who underwent IVUS and FFR, were included in this study. Five patients presented FFR values lower than the 0...

Importance: The increasing burden due to cancer and other noncommunicable diseases poses a threat to human development, which has resulted in global political commitments reflected in the Sustainable Development Goals as well as the World Health Organization (WHO) Global Action Plan on Non-Communicable Diseases. To determine if these commitments have resulted in improved cancer control, quantitative assessments of the cancer burden are required. Objective: To assess the burden for 29 cancer groups over time to provide a framework for policy discussion, resource allocation, and research focus...

AIMS: Randomised controlled trials have reported instantaneous wave-free ratio (iFR) to be non-inferior to fractional flow reserve (FFR) for major adverse cardiovascular events at one year; however, iFR is limited by sensitive landmarking of the pressure waveform, and the assumption that maximal flow and minimal resistance occur during a fixed period of diastole. We sought to validate the resting full-cycle ratio (RFR), a novel non-hyperaemic index of coronary stenosis severity based on unbiased identification of the lowest distal coronary pressure to aortic pressure ratio (Pd/Pa), independent of the ECG, landmark identification, and timing within the cardiac cycle...

Stent placement guided by angiography alone is often inexact, but of increased importance with bifurcation percutaneous coronary intervention (PCI). We describe a novel technique using optical coherence tomography (OCT)-guided angiographic co-registration termed "Bifurcation and Ostial OCT Mapping" (BOOM). The technique is based on the precise identification and mapping of the side-branch ostium using co-registration to minimize protrusion of stent struts into the main branch while ensuring full coverage of the ostium in the side-branch...

AIMS: Among technologies used to assess FFR, a monorail, sensor-tipped micro pressure catheter (PC) may be advantageous for delivery and re-assessment. We sought to determine whether the larger cross-sectional area of the PC influences FFR measurements compared to the pressure wire. METHODS AND RESULTS: PERFORM was a single-center, prospective study designed to determine the precision and accuracy of the PC compared with the pressure wire (PW) for measurement of FFR...

AIMS: We evaluated the effectiveness of excimer laser coronary angioplasty (ELCA) to treat in-stent restenosis (ISR) due to peri-stent calcium-related stent under-expansion as assessed by optical coherence tomography (OCT). METHODS AND RESULTS: We studied 81 patients (81 lesions with ISR, stent under-expansion, and peri-stent calcium >90°) who underwent OCT imaging both pre- and post-percutaneous coronary intervention and compared lesions treated with ELCA (n=23) vs without ELCA (n=58)...

The advent of the fully bioresorbable vascular scaffold (BVS) is the latest step in a series of advancements in the design of intracoronary stents over the past few decades. The novelty of this technology is in providing temporary vessel scaffolding and local antiproliferative therapy to prevent neointimal hyperplasia after percutaneous coronary intervention followed by gradual resorption of the scaffold to restore the native vessel anatomy and physiology-a process termed vascular reparative therapy. Areas covered: The first generation of BVS has not been able to fully match the high benchmark in safety and efficacy set by contemporary metallic drug-eluting stents...

Middle East respiratory syndrome (MERS) is a respiratory disease caused by MERS coronavirus. Because of lack of vaccination, various studies investigated the therapeutic efficacy of antiviral drugs and supportive remedies. A systematic literature search from 10 databases was conducted and screened for relevant articles. Studies reporting information about the treatment of MERS coronavirus infection were extracted and analyzed. Despite receiving treatment with ribavirin plus IFN, the case fatality rate was as high as 71% in the IFN-treatment group and exactly the same in patients who received supportive treatment only...

AIMS: To evaluate the predictability of resting distal coronary pressure wave forms for fractional flow reserve (FFR). METHODS AND RESULTS: Resting coronary wave forms were qualitatively evaluated for the presence of (i) dicrotic notch; (ii) diastolic dipping; and (iii) ventricularization. In a development cohort (n=88) a scoring system was developed that was then applied to a validation cohort (n=428) using a multivariable linear regression model to predict FFR and receiver operating characteristics (ROC) to predict FFR ≤0...

OBJECTIVE: To study outcomes with use of percutaneous mechanical circulatory support (MCS) devices in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We examined characteristics and outcomes of 1598 CTO-PCIs performed from 2012-2017 at 12 high-volume centers. RESULTS: Patient age was 66 ± 10 years; 86% were men. An MCS device was used electively in 69 procedures (4%) and urgently in 22 procedures (1%). The most commonly used elective MCS device was Impella 2...

Background: Intracoronary imaging is an important tool for guiding decision making in the cardiac catheterization laboratory. Sources of data: We have reviewed the latest available evidence in the field to highlight the various potential benefits of intravascular imaging. Areas of agreement: Coronary angiography has been considered the gold standard test to appropriately diagnose and manage patients with coronary artery disease, but it has the inherent limitation of being a 2-dimensional x-ray lumenogram of a complex 3-dimensional vascular structure...

Procedural guidance with intravascular ultrasound (IVUS) imaging improves the clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) by: 1) informing the necessity for lesion preparation; 2) directing appropriate stent sizing to maximize the final stent area and minimize geographic miss; 3) selecting the optimal stent length to cover residual disease adjacent to the lesion, thus minimizing geographic miss; 4) guiding optimal stent expansion; 5) identifying acute complications (edge dissection, stent malapposition, tissue protrusion); and 6) clarifying the mechanism of late stent failure (stent thrombosis, neointimal hyperplasia, stent underexpansion or fracture, or neoatherosclerosis)...

INTRODUCTION: Anastomotic leak and conduit necrosis are devastating complications following Ivor Lewis esophagectomy. Near infrared imaging (NIR) using IndoCyanine Green allows for real time tissue perfusion assessment which may reduce anastomotic leak during minimally invasive Ivor Lewis esophagectomy (MIE).

PURPOSE: The purpose of this study was to report an unusual first manifestation of Coats' disease presenting as an acute angle-closure glaucoma attack in an adult patient. PATIENTS AND METHODS: A 37-year-old African woman presented to the emergency department with severe headache, ocular pain, and no light perception in the left eye. The left pupil was middilated and nonreactive, and the intraocular pressure (IOP) by applanation tonometry was 47 mm Hg.

BACKGROUND: The Absorb bioresorbable vascular scaffold (BVS) completely resorbs within 3 years after coronary artery implantation. The safety and effectiveness of BVS through this critical 3-year period have not been characterized. METHODS: We performed an individual-patient-data pooled meta-analysis of the 4 randomized ABSORB trials in which 3389 patients with coronary artery disease were randomly assigned to everolimus-eluting Absorb BVS (n=2164) or cobalt-chromium everolimus-eluting stents (n=1225)...

OBJECTIVE: To evaluate the performance of non-contrast computed tomography (CT) by reporting the difference in attenuation between normal and inflamed renal parenchyma in patients clinically diagnosed with acute pyelonephritis (APN). MATERIAL AND METHODS: This is a retrospective study concerned with non-contrast CT evaluation of 74 patients, admitted with a clinical diagnosis of APN and failed to respond to 48h antibiotics treatment. Mean attenuation values in Hounsfield units (HU) were measured in the upper, middle and lower segments of the inflamed and the normal kidney of the same patient...
