Multimodal Imaging Analysis in a Case with Congenital Fovea-Involving Retinal Macrovessel and Excellent Visual Acuity

Case Reports in Ophthalmological Medicine, 2017
Purpose. Congenital retinal macrovessels (CRM) represent rare aberrant vasculature of the retinal vessels that can supply or drain the macula. In this report, the optical coherence tomography angiography features of a congenital retinal macrovessel are ...

Temporal Trends and Prognosis in Rotational Atherectomy: A Comparison of Contemporary and Traditional Eras

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Rotational atherectomy (RA) has undergone considerable technical modernization in recent years. This study evaluated whether RA performed in the contemporary era was associated with superior cardiovascular outcomes compared with the traditional era. Aims To compare the clinical characteristics and cardiovascular outcomes of patients

OCT Angiography (abstract)

, 2017
Optical coherence tomography angiography (OCTA) is a non-invasive approach to visualize ocular microcirculation of the capillary plexuses. OCTA is currently in its infancy and can potentially make a significant impact in ophthalmology and neuro ...

Retinal Non-Perfusion in Proliferative Diabetic Retinopathy Before and After Panretinal Photocoagulation Assessed by Wide Field OCT Angiography

American journal of ophthalmology-glaucoma, 2020
Purpose: Wide field swept source OCT angiography (WF SS-OCTA) imaging was compared with ultrawide-field (UWF) fluorescein angiography (FA) imaging to better understand changes in retinal non-perfusion before and after panretinal photocoagulation (PRP) in

Maximum Allowable Contrast Dose and Risk of Acute Kidney Injury After Coronary Procedures

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Recent studies have questioned whether iodinated contrast is causally related to acute kidney injury (AKI). AIM We pursed a contemporary analysis to determine the impact of contrast dose on AKI following coronary procedures in an era of lower contrast doses and less nephrotoxic agents.

Spontaneous retinal-choroidal anastomosis in a case of branch retinal vein occlusion

American Journal of Ophthalmology Case Reports, 2018
Purpose: To report a case of a patient affected by branch retinal vein occlusion (BRVO) showing a possible spontaneous retinal-choroidal anastomosis (RCA) at the level of the fovea. Observations: A 72 years old male patient with diagnosis of BRVO of left

Changes in Retinal Vessel and Retinal Layer Thickness After Vitrectomy in Retinal Detachment via Swept-Source OCT Angiography

Investigative Ophthalmology and Visual Science, 2020
Purpose To compare postvitrectomy retinal and choroidal vessel density (VD) and retinal layer thickness between eyes with macula-off and macula-on rhegmatogenous retinal detachment (RRD) using swept-source optical coherence tomography (SS-OCT) and ...

Incidence of Periprocedural Myocardial Injury and Infarction After Intravascular Lithotripsy for Calcified Coronary Artery Stenosis

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Intravascular lithotripsy (IVL) has emerged as an effective technique for modifying heavily calcified coronary plaques, facilitating optimal stent expansion while minimizing procedural complications. However, data on periprocedural myocardial injury (PMI) and infarction (PPMI) following IVL remain scarce.

Optical coherence tomography (OCT) - versus angiography-guided strategy for percutaneous coronary intervention: a meta-analysis of randomized trials

BMC Cardiovascular Disorders
Background Optical coherence tomography (OCT) guidance in percutaneous coronary intervention (PCI) has been shown to improve procedural outcomes. However, evidence supporting its superiority over angiography-guided PCI in terms of clinical outcomes is ...
