We have the honor to invite you to participate in the Latin American Registry of Percutaneous Interventions in Coronary Bifurcations – LATAM Bif Registry. Coronary bifurcations represent a field of particular interest in interventional cardiology, representing 15-20% of coronary angioplasties performed in our daily practice. The LATAM Bif Registry is the scientific research program of the...
Achieving rapid and maximum inhibition of platelet aggregation can reduce complications related to scheduled percutaneous coronary intervention (PCI) in chronic coronary syndromes (CCS). Over the last few decades, the optimal timing for initiating P2Y12 inhibitors and their appropriate dosage have been the subject of numerous studies; however, they have not been clearly established yet. Higher...
Diabetic patients have twice as high a risk of developing coronary artery disease (CAD). Additionally, CAD increases mortality risk. Patients with a history of percutaneous coronary intervention (PCI) tend to need repeat revascularization, even with second generation stents. To date, there are few studies assessing the role of glycemic control in stent failure, stent thrombosis,...
At present, most percutaneous coronary intervention procedures (PCI) are done with drug eluting stents (DES). However, drug coated balloons (DCB) have shown benefits in restenosis and small vessel de novo lesions. Intravascular ultrasound (IVUS) has been shown effective in left main PCI and complex procedures, even though there is little infomration on its use for...
The presence of calcification in the coronary arteries (CAC) remains the main challenge in the percutaneous treatment of these lesions. Various studies have demonstrated the association of CAC with unfavorable long-term outcomes. Intravascular lithotripsy (IVL) has emerged as an effective tool for fracturing calcified plaques. Studies evaluating this strategy have shown high device success rates,...
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...
