The Current Role of Thrombus Aspiration in Primary PCI

The Current Role of Thrombus Aspiration in Primary PCI

In general, thrombus aspiration in acute myocardial infarction (AMI) has not been shown beneficial by large studies. It could even be prejudicial, since it has been associated with stroke. However, there are certain scenarios where the presence of a significant number of these prevents us from reaching adequate TIMI flow 3, or is associated with

Coronary Flow Reserve in Patients with Intermediate FFR: Should We Use This Tool to Define When to Perform Coronary Angioplasty?

Current guidelines recommend using fractional flow reserve (FFR) to guide coronary angioplasty. However, intermediate FFR values (0.75-0.80) generate uncertainty about the prognostic value of performing coronary angioplasty over optimal medical treatment. The use of coronary flow reserve (CFR) together with FFR provides further insight into coronary circulation because CFR is an index that also includes

Coronary Angioplasty Evolution According to Syntax II: 5-Year Followup

It has been long since the SYNTAX (NEJM 2009) came out comparing percutaneous coronary intervention (PCI) against coronary artery bypass grafting (CABG). That emblematic study associated PCI with first generation drug eluting stents (Taxus) with increased major cardiac and cerebrovascular events (all-cause mortality, AMI, stroke, or any revascularization – MACCE) vs. CABG, at 5 years,

IVUS-Guided Coronary Angioplasty: Promising Results at 3-Year Follow-Up

Intravascular ultrasound (IVUS) to guide drug-eluting stent (DES) implantation has been evaluated in several studies. Two randomized studies, IVUS-XPL (Impact of Intravascular Ultrasound Guidance on the Outcomes of Xience Prime Stents in Long Lesions) and ULTIMATE (Intravascular Ultrasound Guided Drug Eluting Stents Implantation in All-Comers Coronary Lesions), have shown fewer repeat revascularizations compared with angiography-guided

OCT in STEMI Patients: Is It Safe to Prevent Stenting?

Percutaneous coronary intervention in patients with acute myocardial infarction (AMI) where the physiopathological mechanism is plaque erosion or non-atherosclerotic mechanisms (such as spontaneous coronary artery dissection) is not beneficial according to recent studies.  The EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion) has shown medical treatment with no

ACC 2022


Percutaneous coronary intervention improves angina related quality of life in AMI patients with multivessel disease. The COMPLETE study has shown patients receiving complete revascularization compared against culprit-only revascularization presented lower cardiovascular rate or AMI at 3-year followup. ACC featured a COMPLETE subanalysis assessing angina related quality of life.  It included 4041 patients, mean age 62,

IVUS in Femoropopliteal PCI: Should We Start Using It?

For approximately two decades now, PCI has been the treatment of choice in femoropopliteal territory, and even though technological developments and increasing operator experience have indeed improved outcomes, IVUS (which has showed great benefits in PCI, even reducing left main mortality) is hardly used in this territory.  This was a prospective randomized controlled study including

Post-PCI Ticagrelor Monotherapy in High-Risk Bleeding

In patients at high risk of bleeding undergoing coronary PCI and after completing 3-month DAPT with no events, you may discontinue aspirin and follow up with ticagrelor monotherapy. This will significantly reduce bleeding without increasing ischemic events.  With this strategy, the greater the risk of bleeding, the greater the absolute reduction of bleeding. Patients at

The FDA Approves Intravascular Lithotripsy for Calcified Lesions

The US Food and Drug Administration (FDA) has cleared the shockwave lithotripsy system to treat severely calcified plaque lesions. The device uses a balloon to release pressure sound waves capable of passing through the softest material, and possibly rupture calcified plaque and optimize stent implantation. As such, it has the potential to replace or, at

AHA 2021 | Meta-análisis de cirugía vs angioplastia para el tronco de la coronaria izquierda

AHA 2021 | Meta-Analysis of Surgery vs. Angioplasty in Left Main Coronary Artery Disease

According to this new meta-analysis (presented at AHA 2021 and published in The Lancet), mortality is similar between surgery and angioplasty to treat left main coronary artery in patients with simple or intermediate anatomy. This new study estimates that, after 5 years, mortality with surgery would be 11.2% vs. 10.2% with angioplasty, a non-significant difference. This debate
