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...
IN.PACT Outcomes at 5 Years
Over time, percutaneous coronary intervention (PCI) with drug coated balloons (DCB) have been shown more beneficial than conventional PCI. However, in many cases, stenting is required to treat suboptimal results. Even though several studies have looked into this scenario, long term durability still calls for research. This was a 5 year thorough analysis of the...
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...
Post TAVR Long Term Outcomes in Patients with Chronic Inflammatory Disease
Patients suffering from immune-mediated chronic inflammatory disease (CID) face a high risk of developing heart disease, including aortic valve disease. Inflammatory vascular disease when triggered by an autoimmune condition, can prompt a harmful response leading to valve degeneration, with increased calcification and fibrosis, and the associated progression of stenosis, failure or both. Prior research has...
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...
Motivation Survey and Barriers to Interventional Cardiology Training in Latin America – MIL Group
Interventional cardiology is one of the medical specialties of fastest development in the last 20 years. In Latin America, interventional cardiology is no stranger to the European trend where our career path chosen mostly by men, despite the growing population of medical school female enrolment. This poll on barriers and motivation to choosing an interventional...
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...
Edge-to-Edge Repair in Cardiogenic Shock
The edge-to-edge approach with MitraClip has been established as a valid strategy for patients who experience severe symptomatic mitral regurgitation (MI) with high risk for surgery, currently with a IIa indication. MI complicated by cardiogenic shock, which results in a high risk for conventional valve surgery, is a particularly complex scenario. In such a case,...
