iFR en lesiones no culpables: el momento de la medición parece cambiar la historia

iFR Assessment of Intermediate Aortic Stenosis Lesions Consolidates

iFR Assessment of Intermediate Aortic Stenosis Lesions Consolidates

Once a big void that prevented us from effectively assessing functional compromise, intermediate aortic stenosis has made us treat many lesions “just in case”, to save us what would be a complicated procedure, had a valve been placed. Auspiciously, some light has been shed by several, most welcome, studies simultaneously published in J Am Coll

¿Qué usar para medir funcionalmente una lesión coronaria en el contexto de estenosis aórtica severa?

What Should We Use for the Functional Assessment of Coronary Lesions in Severe Aortic Stenosis?

This systematic analysis measured intracoronary pressure in different phases of the cardiac cycle and flow velocity in patients with severe aortic stenosis and coronary artery disease, who were scheduled for transcatheter aortic valve replacement (TAVR). The aim was to determine the impact of aortic stenosis on: 1) flow, at different phases; 2) hyperemic coronary flow;

Safety of Lesion Deferral with iFR or FFR in Both Stable and Acute Patients

Overall, deferral of lesion revascularization is equally safe with both fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR), with a low rate of events of about 4%. Lesions were more frequently deferred when iFR (as opposed to FFR) was used for functional assessment. Among patients with deferred lesions, acute patients experienced significantly more events

TCT 2018 | FAST-FFR: Angiography-Derived FFR Without Hyperemic Stimulus or Invasive Guidewire Placement

All over the world, functional lesion measurement remains underutilized due to the need for a hyperemic stimulus (which may be avoided with instantaneous wave-free ratio [iFR]) and, above all, the invasiveness of guidewire placement (crossing the intended lesion) for the measurement. These guidewires have improved a lot, but they still lack the navigating capacity of

FUTURE: una piedra en el zapato para el FFR y más preguntas que respuestas

ESC 2018 | FUTURE: A Thorn in FFR and More Questions than Answers

As observed at the preliminary analysis that motivated the FUTURE trial early termination, the use of fractional flow reserve (FFR) to guide revascularization in an unselected population with multivessel disease was associated to twice the mortality rate in one year, with no beneficial impact on other end points. Even though the combined end point of

FFR vs Angiography Guided CABG

In the daily practice and in randomized studies such as Syntax or Freedom, most cardiovascular surgeons across the world use angiography guided CABG to teat 50% coronary stenosis. Many of these lesions might not be functionally significant. There is abundant evidence in favor of fractional flow reserve (FFR) guided PCI, but FFR guided CABG is

Real-Life Functional Assessment of Coronary Stenosis: We Are Yet to Convert to It

The use of functional assessment of coronary stenosis (following the class IA recommendation in both American and European guidelines) is below 50% in daily clinical practice. Truth be told, most operators continue having blind faith in angiography. The inclusion of coronary physiology in the decision-making process has spread widely across countries, sites, and operators. The ERIS

Angina Is as Subjective as Any Other Pain

Almost 80% of all patients randomized in this study reported Canadian Cardiovascular Society class II or III angina, and almost all of them (97%) had more than 1 positive non-invasive ischemia test that matched the area of their single diseased coronary vessel. Beyond fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR), the study randomized patients to

EuroPCR 2018 | SYNTAX II: Results at 2 Years for Best Angioplasty vs. Surgery in Multivessel Disease

Since the publication of the original SYNTAX trial, there have been great technical advancements that have influenced the results of angioplasty: New tools for risk stratification using the SYNTAX II score which integrate clinical and anatomical variables to the team’s decision-making process. Functional revascularization (hybrid use of fractional flow reserve or instantaneous wave-free ratio). Optimization of

EuroPCR 2018 | Compare-Acute: FFR or Primary Angioplasty at a 2-Year Follow-Up After Complete Revascularization

Recent studies in patients undergoing acute myocardial infarction showed that a complete revascularization strategy in an acute or subacute setting, whether it be guided through angiography (PRAMI, CvLPRIT) or fractional flow reserve (FFR) (PRIMULTI, COMPARE-ACUTE), improves the combined endpoint of major adverse cardiac events (MACE) when compared with treatment of the culprit artery only.
