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…
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…
Revascularization vs. Deferral of Physiologically Significant Lesions in the Left Main Coronary Artery
Most randomized studies on decision-making in coronary artery disease revascularization exclude left main coronary artery disease (LMCAD), as did the ISCHEMIA Study. On the other hand, the benefits of functionally assessing lesions, proven in studies such as FAME, emphasize the importance of this tool in guiding revascularization decisions. However, there is still little understanding of…
We Should Revascularize Patients with Stable Coronary Syndromes and Ischemia Assessed by iFR
Chronic stable angina has shown a good response to medical treatment, and the Ischemia study has recently demonstrated the safety of such treatment in stable chronic angina with moderate to severe ischemia. However, this study excluded left main coronary artery (LMCA) lesions. The FAME Study has shown the safety and efficacy of fractional flow reserve…
Left Main Coronary Artery Percutaneous Coronary Intervention: Evolution and Results over Time
Left main coronary artery percutaneous coronary intervention (LMCA PCI) is a treatment option that is increasingly used in our setting. One of the reasons for choosing this therapeutic strategy is the improvements in devices and techniques. However, the long-term results of LMCA PCI are not well established. The aim of this retrospective study was to…
Left Main Coronary Artery PCI Using State-of-the-Art Zotarolimus-Eluting Stents
Percutaneous coronary intervention (PCI) to the left main coronary artery (LMCA) with drug-eluting stent implantation is currently a major challenge due to the size of the vessel, the compromise of a bifurcation lesion in important branches, and the potential risk of complications. Available information on LMCA PCI comes from studies where DES stents were implanted…
Real-World Revascularization Strategy for Left Main Coronary Artery: Surgery or PCI?
There are many current randomized trials comparing percutaneous coronary intervention (PCI) with myocardial revascularization surgery (MRS) for the treatment of left main coronary artery disease (LMCAD). In the European Society of Cardiology guidelines, PCI is classified as Ia (LMCAD with low-complexity coronary disease) or IIa indication (intermediate complexity), whereas, according to the American Heart Association…
Long-Term Mortality in Non-Obstructive Lesions in the Left Main Coronary Artery
Left main coronary artery (LMCA) intervention with significant lesions on both coronary angiography and intravascular ultrasound (IVUS), either through angioplasty (PCI) or myocardial revascularization surgery (MRS), is directly related to a decrease in long-term adverse clinical events. However, the relationship between subclinical LMCA disease (preserved luminal diameters) and long-term mortality is still unknown. A retrospective…
Provisional vs Dual Stenting in Left Main: An Endless Discussion?
True left main stem bifurcation patients have shown fewer adverse events with stepwise provisional stenting vs systematic dual stenting as first strategy, even though the difference was not significant. Usually, for any other vessel, the preferred technique is provisional stenting. However, when it comes to the left main, there is a randomized, dedicated, well designed…
