Long-Term Mortality in Non-Obstructive Lesions in the Left Main Coronary Artery

Long-Term Mortality in Non-Obstructive Lesions in the Left Main Coronary Artery

Left main coronary artery (LMCA) intervention with significant lesions on both coronary angiography and intravascular ultrasound (IVUS), either through angioplasty (PCI) or myocardial revascularization surgery (MRS), is directly related to a decrease in long-term adverse clinical events. However, the relationship between subclinical LMCA disease (preserved luminal diameters) and long-term mortality is still unknown. A retrospective

Primary vs Secondary Retrograde Approach in CTO: Differences

Successful chronic total occlusion procedures are on the rise, especially in high volume centers, seeing as they count on more sophisticated materials and different techniques, such the retrograde approach. However, the significant increase of success rate with this technique has also brought along an increase in associated complications.  The aim of this study was to

The Best of the SOLACI-SOCIME 2022 Main Arena: Day 3

Lecture by Dr. Hector García García – LM-PCI: IVUS and FFR/IFR? Dr. Hector García delivered an excellent presentation on whether we should use intravascular ultrasound (IVUS) or fractional flow reserve (FFR)/instantaneous wave-free ratio (iFR) in the left main coronary artery (LMCA) to consider severe obstruction, since there is significant interobserver variability with angiography. Although the

The Best of SOLACI-SOCIME 2022 Main Arena – Chronic Total Occlusions (CTO)

How to Choose the Best Approach in Chronic Total Occlusions, by Dr. Jean-Michel Paradis CTO are present in around 16 to 20% of patients with coronary artery disease who get a coronary angiography. CTO Percutaneous intervention has been on the rise, mainly due to equipment and technique advancement. During his presentation, Dr. Paradis mentioned the

Cortar las valvas, una medida extrema para evitar la oclusión coronaria post TAVI

CTO: Trials vs. Real-World

Percutaneous coronary intervention of chronic total occlusions (CTO) is currently indicated for symptom improvement, as studies have inadequate randomization of data which hinders the assessment of hard outcomes. However, patient inclusion in randomized controlled trials has been challenging, especially for highly symptomatic and higher risk patients. This causes a selection bias in randomized studies on

Resultados a 2 años de los stents liberadores de Zotarolimus vs stents libres de polímero liberadores de Biolimus. ¿Son seguros en pacientes con alto riesgo de sangrado?

Longitudinal Deformation of a Stent with the POT Technique

The fractal geometry of coronary bifurcations offers a mismatch between the proximal diameter of the main branch and the distal branches that make up the bifurcation. Angioplasty in this area can be performed through different techniques depending on plaque distribution, and the particular geometry of each bifurcation. Overall, and regardless of the strategy used, there

Progress-CTO Score: A Key New Tool to Plan CTO

Intervention of chronic total occlusions (CTO) through angioplasty (PCI) can cause complications, even in highly experienced centers. Plenty has been written on the probability of success for the treatment of CTOs using scores such as CL-SCORE, J-CTO, ORA, E-CTO, CASTLE-CTO, etc. (some of which are usually used when preparing these cases). However, besides estimating success

Changes in Coronary Collateral Function Post CTO Intervention

In the last few years, we have seen significant growth of chronic total occlusion (CTO) percutaneous intervention, which has also been considered for patients with viable territory that remain symptomatic. Experienced centers present successful CTO intervention rates close to 90%, especially with a hybrid approach. However, it is still a complex procedure, and target vessel

Resultado a 3 años luego de ATC con técnica de 2- stents vs Provisional stent por bifurcaciones complejas

Three-Year Outcomes after CTA with 2-Stent Technique Vs. Provisional Stenting for Complex Bifurcation Lesions

The prevalence of coronary lesions with bifurcation involvement is about 20% in patients undergoing coronary angiography (CTA). While provisional stenting is overall the most accepted technique, the 2018 myocardial revascularization guidelines recommend the 2-stent technique for complex bifurcation lesions, defined as side branch with lesion >5mm, distal reference diameter of the side branch ≥2.75, or

Coronary Bifurcation Lesions: MRS or PCI? 10-Year Mortality of the SYNTAX Study

Percutaneous treatment of coronary lesions affecting bifurcations has increased in recent decades. Coronary angioplasty (percutaneous coronary intervention, PCI) in these cases is associated with an increased rate of adverse events in patients with multivessel disease and left main coronary artery lesions. The SYNTAX score, which is a predictor of total mortality, is used to evaluate

EuroPCR 2022 | The IMPROVED-CTO Trial

PCI success rate in chronic total occlusion (CTO), according to some registries, is below 80%. These failed revascularization procedures might lead to quality-of-life deterioration and shorter survival. This concern has driven the development of new techniques and technologies in an attempt to increase PCI success. Today, approximately 20% of CTOs are treated with a second
