When deciding on the optimal coronary artery revascularization treatment of coronary artery disease (CAD) patients, physicians normally assessed clinical presentation, surgical risk, survival expectation, and the likelihood of a better quality of life. Decisions are made after careful consideration, by the Heart Team, who will ponder options such as coronary artery bypass graft (CABG), percutaneous…
Complex PCI in Octogenarian
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…
Antiplatelet Treatment with Ticagrelor vs. Clopidogrel in Patients with Chronic Coronary Syndrome
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…
Glycemic Control and Coronary Stent Failure
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,…
Coronary Angioplasty with Sirolimus Eluting Stents
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…
Patients with CABG History and new N-ST ACS: Routine Invasive Strategy?
Multiple studies support the use of an early invasive approach in high risk patients with non-ST elevation acute coronary syndrome (NST ACS). This benefit of an invasive strategy over the expected management has been shown in randomized studies and meta-analysis. Patients with a history of cardiac artery bypass graft (CABG) represent approximately 10% of ACS…
Long Term Outcomes of Hyperemic Stenosis Resistance Index (HSR) in Patients with Stable Chronic Angina
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…
BIONYX: Onyx vs. Orsiro At 5 Years
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…
Pre-Catheterization Fast
It has been generally established that coronary procedures with local anesthesia and moderate sedation minimally require a 6 hour fast for solids and 2 hours for liquids (according to SCAI guidelines 2021). However, complications requiring emergency orotracheal intubation are extremely rare. Prolonged fasting can have adverse effects such as hypoglycemia, insulin resistance, acute renal failure…
CART Technique for Chronic Total Occlusions
The retrograde technique has significantly improved the success of percutaneous treatment of chronic total occlusions (CTO). After crossing a collateral channel, creating a connection between the anterograde and retrograde systems is key. The most common technique for this is reverse controlled antegrade and retrograde subintimal tracking (reverse CART). This technique involves inflating a balloon over…
Microvascular Resistant Reserve: Impact on STEMI Patients
Coronary Microvascular Dysfunction (CMD) is being increasingly considered a common consequence of STEMI. Its presence partly explains the persistence of angina symptoms in over 50% of patients after PCI, despite successful epicardial artery reperfusion. Also, CMD has been independently associated with worse left ventricular ejection fraction recovery, which leads to worse prognosis, including recurrent events,…
