Dual Role of Guide Extension Catheters for the Management of High Thrombus Burden in STEMI: Case Report and Mini Review.

High thrombus burden in ST segment elevation myocardial infarction (STEMI) patients increases the risk of adverse events. In this report, we review current strategies for high thrombus burden and present a case report with the combination of two different techniques: aspiration through a guide extension catheter followed by local intracoronary thrombolysis with 'marinade' technique.

Economic benefits of fractional flow reserve utilization on intermediate lesions and its clinical impact after one year-follow up.

Background: Fractional flow reserve (FFR) is a proven technology for guiding percutaneous coronary intervention, but it is not reimbursed despite the fact that it frequently allows to defer revascularization. Our goal was to determine the economic benefit of FFR on intermediate lesions, as well as the clinical endpoints at 1 year follow up.

Methods: Observational prospective study that included consecutive patients with intermediate lesions evaluated with FFR between April 2013 and March 2016.

A simple prediction rule for significant renal artery stenosis in patients undergoing cardiac catheterization.

Background: Renal artery stenosis (RAS) is a potentially reversible cause of hypertension and renal insufficiency and is associated with poor prognosis.

Methods: We aimed to identify simple predictors of significant RAS among patients undergoing coronary angiography. Prospective data were collected on 843 consecutive patients who underwent cardiac catheterization and abdominal aortography.
