Technological advancements and technique improvements have significantly enhanced the success rate of percutaneous interventions for treating chronic total occlusions (CTO). Angiographic scores and CTO-PCI algorithms are valuable tools that help us select the optimal strategy when planning these procedures. The retrograde strategy, specifically, has proven beneficial in addressing complex CTOs. However, standardized tools to predict...
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....
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...
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...
Complementary imaging allows for the identification of numerous scenarios not visible with conventional angiography (ICA), both for the assessment of differential diagnoses and the improvement of percutaneous coronary intervention (PCI) outcomes. Advantages include assessment of plaque characteristics, vessel plaque burden, stent edge dissection, vessel diameter, and correct apposition, among others. While intravascular ultrasound (IVUS) was...
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...
The first experiences with distal radial access (DRA) have revealed significant benefits compared against the transradial approach (TRA), showing reduced bleeding events and better puncture site occlusion rate. Even the spectrum of diseases treated with DRA has grown, and now includes chronic total occlusion (CTO) though 7Fr inductors, such as Terumo’s Glidesheath Slender. The aim...
Aortic stenosis shares risk factors with coronary artery disease (CAD), and its prevalence varies according to age, reaching approximately 50% or more in some registries. Deciding when to treat and the need for percutaneous intervention presents a challenge. It has been established that epicardial stenosis at proximal level, or the medial segment, requires intervention, especially...
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...
