Early Multicenter Outcomes of Dedicated Transcatheter Aortic Valve Replacement for Left Ventricular Assist Device‐Associated Pure Aortic Regurgitation

Artificial Organs, EarlyView.
LVAD‐associated aortic regurgitation impairs circulatory support, with limited surgical and off‐label options. In a multicenter registry (n = 30), the AR‐dedicated JenaValve Trilogy TAVR eliminated AR, achieving 96.7% (29/30) technical success and 93.3% (28/30) device success (VARC‐3), with 3.3% (1/30) 30‐day mortality.

The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence ‐ OMEGA report 3

Acta Ophthalmologica, EarlyView.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age‐related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify the GA area in a monocentric study.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Adult‐onset Coats disease: A systematic review and meta‐analysis of imaging biomarkers and targeted therapies

Acta Ophthalmologica, EarlyView.
Abstract Coats disease diagnosed in adulthood is a rare idiopathic retinal telangiectatic vasculopathy that may differ in phenotype from childhood‐diagnosed cases. This systematic review synthesizes current evidence to characterize its clinical spectrum, imaging features, treatment outcomes and underlying mechanisms, with a focus on immunovascular ...

The effect of rhegmatogenous retinal detachment on retinal oxygenation

Acta Ophthalmologica, EarlyView.
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

The role of optical coherence tomography in detecting and correcting stent malapposition during primary percutaneous coronary intervention: A case series and review of current practice

Heart India
Primary percutaneous coronary intervention (PCI) is the gold standard for treating acute myocardial infarction (AMI). Stent malapposition, a complication more common in AMI due to plaque disruption and thrombus burden, increases the risks of stent ...
