Chronic total occlusion (CTO) affect up to 20% of patients undergoing angiographic diagnostic tests. During the last two decades, recanalization technique refinement, the development of specific devices and operator skill improvement have elevated procedural success rate up to 90%. However, there are still particular complications such as collateral perforation and access site complications. This is…
EXCEL Study: Complete vs. Incomplete Revascularization
Regardless of whether it is attempted through percutaneous coronary intervention (PCI) or myocardial revascularization surgery (MRS), complete revascularization (CR) is not always achieved. Overall, it is more frequent with surgery than with percutaneous treatment. Additionally, incomplete revascularization (IR) has proven to be associated with worse outcomes compared to CR. Researchers conducted an analysis of the…
Physiologically Significant Obstructions in the Left Main Coronary Artery: Revascularizing vs. Deferring
Most randomized studies on revascularization in stable coronary artery disease exclude left main coronary artery disease (LMCAD). One example of this was the ISCHEMIA study. However, the benefits of functional lesion assessment, as demonstrated in the FAME studies, highlight the importance of this tool in guiding decisions regarding revascularization. Nevertheless, the clinical outcomes of patients…
Rehospitalization After Treatment of Left Main Coronary Artery Disease and Its Prognosis: Sub-Analysis of the EXCEL Study
Individual randomized studies have shown variable results regarding the mortality risk following treatment of left main coronary artery disease (LMCAD), either through percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG). However, upon assessment of the latest meta-analyses (with matched data), similar risks of all-cause and cardiovascular mortality have been reported for both groups.…
Lithotripsy in the Left Main Coronary Artery
A lesion ≥50% in the left main coronary artery (LMCA) is considered severe, according to various scientific societies, regardless of the presence of symptoms or ischemia, due to the extent of myocardium at risk. In such cases, revascularization is indicated. In many patients, lesions in this section of the coronary artery have severe calcification, which…
ERCTO Registry: Current Results for Percutaneous Treatment of Chronic Total Occlusions
Chronic total occlusions (CTO) occur in up to 20% of patients undergoing diagnostic angiographic studies. Over the past two decades, the optimization of recanalization techniques, the development of new specialized devices, and improvement in operator skill have contributed to an increased procedural success rate, reaching 90%. However, specific complications such as collateral perforation and access…
Proximal Optimization Technique in Unprotected LMCA
Proximal optimization technique (POT) has been recommended as a standard strategy in bifurcation lesions because it facilitates proper stent implantation and apposition in the proximal main vessel, according to the European Bifurcation Club. Percutaneous coronary intervention (PCI) of the unprotected left main coronary artery (LMCA) has specific characteristics, and the long-term impact of this strategy…
Use of Intravascular Lithotripsy in Left Main
The Left main coronary artery supplies circulation to roughly 70% of myocardium, and left main disease requires a high risk intervention with significant impact on patient prognosis. The current guidelines have set the threshold for intervention in LM disease at ≥50% stenosis, irrespective of the presence of symptoms or ischemic burden. LM calcification is an…
Recurrent Revascularization at 10 Years after Percutaneous Treatment of DES In-Stent Restenosis
In stent restenosis (ISR) continues to be the main limitation to the percutaneous treatment of coronary artery disease, with 5 to 10% prevalence after new generation DES stenting. Guideline recommendations for this intervention include new DES stenting and the use of drug coated balloons (DCB). Recurrent ISR stenting rate ranges between 10 and 40%, and…
Contemporary Outcomes of CTO PCI in Europe: The ERCTO Registry
Roughly 20% or coronary angiographies show some form of chronic total occlusion (CTO), and this figure is twice as high for diabetic patients or those with cardiac failure and reduced ejection fraction (EF). CTO percutaneous intervention (PCI) has experienced a significant growth thanks to the development of new techniques and dedicated material. However, a considerable…
Long-term Results of Coronary Bifurcation Lesion Treatment in Diabetic Patients
The effects of diabetes on patients with coronary artery disease are well-known, and their outcomes after angioplasty are less favorable, with a higher rate of restenosis, recurrent acute myocardial infarction, and stent thrombosis. Despite advances in drug-eluting stents and procedural techniques, the treatment of coronary bifurcation lesions in diabetic patients shows less positive clinical outcomes…
