On the one hand, chronic peripheral vascular disease is on the rise. On the other, over the past 20 years, percutaneous coronary intervention (PCI) has gained considerable ground thanks to various new devices, replacing surgery as an alternative in most scenarios. Both strategies have shown similar results, but PCI has fewer complications and shorter hospital stays....
ACC 2024 | PREVENT Study
The use of intravascular imaging to identify vulnerable plaque (VP) has proven to be very useful, as such plaque is associated with an increase in major adverse cardiac events. Optimal medical treatment is currently considered the standard strategy to stabilize VP. However, the safety and effectiveness of preventive treatment with percutaneous coronary intervention (PCI) in...
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....
Use of IVL in Calcified Coronary Lesions in a Real World Population
The presence of calcification in coronary arteries (CAC) remains a challenge for the percutaneous treatment of these lesions. Several studies have established the link between CAC and poor long term results. Intravascular lithotripsy (IVL) has surged as a tool to induce calcified plaque fracture. Even though studies on this strategy are not randomized, they have...
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...
Survey on Hemodynamics Centers in Latin America – SOLACI, Stent Save a Life! and South American Society of Cardiology Initiative
The treatment of ST-segment elevation myocardial infarction (STEMI) in Latin America is highly diverse. There are notable differences between countries and even among regions within a single country. It is clear that the treatment of STEMI is still an unmet need in our region. SOLACI and the Stent – Save a Life! Initiative in Latin...
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...
Network Meta-Analysis of Complementary Imaging (IVUS/OCT + Conventional Angiography) for Coronary Stenting
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...
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...
