Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.

PCSK‐9 Inhibitors Can Significantly Improve the Coronary Slow Flow Caused by Elevated Lipoprotein (a) in ST‐Elevation Myocardial Infarction Patients With Chronic Kidney Disease

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Coronary slow flow and no reflow significantly predict poor prognosis in acute myocardial infarction (AMI) patients, especially those with chronic kidney disease (CKD). Early identification of factors contributing to these conditions can mitigate ischemic events and improve outcomes.

Measuring Global Multi-Scale Place Connectivity using Geotagged Social Media Data [PDF]

open access: yesarXiv, 2021
Shaped by human movement, place connectivity is quantified by the strength of spatial interactions among locations. For decades, spatial scientists have researched place connectivity, applications, and metrics. The growing popularity of social media provides a new data stream where spatial social interaction measures are largely devoid of privacy ...

Diagnostic Accuracy of Angiography‐Derived Murray Law‐Based Quantitative Flow Ratio (μQFR) Versus Pressure‐Derived Fractional Flow Reserve (FFR) in Moderate to Severe Calcified Coronary Lesions—The DIAMOND Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Murray law‐based Quantitative Flow Ratio (μQFR) is an innovative AI‐driven method for evaluating coronary lesions using contrast flow velocity estimates. Unlike traditional approaches, μQFR does not require pressure wires or hyperemia induction.
