Multivessel disease is often present in ST elevation acute myocardial infarction (STEMI) patients. The AHA/ACC 2021 revascularization guidelines recommend staged complete revascularization as class I, single-setting complete revascularization as class 2b, and recommend against culprit only revascularization. At present, we have more randomized studies (BIOVASC, FIRE and MULTISTAR) comparing staged vs single-setting complete revascularization, but...
Percutaneous coronary intervention (PCI) with drug eluting stents (DES) can present limitations, especially in the form of stent thrombosis or instent restenosis (ISR). These findings have furthered the development of drub coated balloons (DCB). The safety and efficacy of DCB have already been shown in the context of ISR and de novo small vessel coronary...
While transcatheter aortic valve replacement (TAVR) has shown benefits, significant coronary artery disease affects 50% or more of patients who undergo such procedure. However, it is still unclear which is the best treatment strategy or how to handle this condition. Quantitative flow ratio (QFR) could be a non-invasive option to assess the severity of coronary...
The octogenarian population has already reached 137 million and continues to grow. It is estimated to triple by 2050. This increase represents a big challenge, seeing as these patients are often more fragile, present more complex coronary artery disease and multiple comorbidities. This generally requires two or more procedures and more experience both from operators...
One of the limitations of aortic bioprostheses is their durability. When these devices fail, percutaneous valve implantation is a valid strategy. However, it has been shown that there may be high gradients involved. This gradient increase has been associated with worse outcomes and higher mortality rates, as observed in the PARTNER 2 study at 12 months....
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 hyperemic stenosis resistance index (HSR) was introduced as a more complete hemodynamic severity indicator of a coronary lesion. HSR combines both pressure drop across a lesion and the flow through it, therefore overcoming the limitations of traditional indices such as fractional flow reserve (FFR) and coronary flow reserve (CFR). The aim of this multicenter...
Onyx is a zotarolimus-eluting stent (ZES), designed with thin struts and a platinum core that enhances its radiological visibility. This can be beneficial in complex situations with limited visibility, such as in patients who are obese or present severe calcification, two particularly frequent characteristics in diabetic or elderly patients. The BIONYX study was a randomized...
