percutaneous coronary revascularization

In acute coronary syndromes (ACS), revascularization is the standard of care. However, trials comparing contemporary coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are limited. Optimal revascularization in patients with multi-vessel coronary artery disease (MV-CAD) presenting with ACS is unclear. This is a multi-centred, retrospective observational study from a large, hospital system in the United States. We abstracted data on patients with MV-CAD and ACS from 2018 to 2022 who underwent revascularization with PCI, CABG or medically managed (MM)...

BACKGROUND: The registry-based randomized VALIDATE-SWEDEHEART trial (NCT02311231) compared bivalirudin vs. heparin in patients undergoing percutaneous coronary intervention (PCI) for myocardial infarction (MI). It showed no difference in the composite primary endpoint of death, MI, or major bleeding at 180 days. Here, we report outcomes at two years. METHODS: Analysis of primary and secondary endpoints at two years of follow-up was prespecified in the study protocol...

IMPORTANCE: There have been heterogeneous results related to sex differences in prognosis after percutaneous coronary artery intervention (PCI) for complex coronary artery lesions. OBJECTIVE: To evaluate potential differences in outcomes with intravascular imaging-guided PCI of complex coronary artery lesions between women and men. DESIGN, SETTING, AND PARTICIPANTS: This prespecified substudy evaluates the interaction of sex in the investigator-initiated, open-label, multicenter RENOVATE-COMPLEX-PCI randomized clinical trial, which demonstrated the superiority of intravascular imaging-guided PCI compared with angiography-guided PCI in patients with complex coronary artery lesions...

BACKGROUND: Recently, machine learning algorithms have identified preprocedural γ-glutamyl transferase (GGT) as a significant predictor of long-term mortality after coronary revascularization in the SYNTAX (Synergy Between PCI [Percutaneous Coronary Intervention] With Taxus and Cardiac Surgery) trial. The aim of the present study is to investigate the impact of preprocedural GGT on 10-year all-cause mortality in patients with complex coronary artery disease after revascularization...

BACKGROUND: The study assessed the outcomes of patients undergoing percutaneous coronary intervention (PCI) to bypass grafts, focusing on all-cause mortality and target vessel failure (TVF) rates. METHODS: A single-centre registry analysis included 364 patients who underwent PCI on coronary bypass grafts between 2008 and 2019. The study analyzed all-cause mortality and TVF, which encompassed target lesion revascularization, target vessel revascularization, and medically treated occluded target graft post-PCI...

Background The impact of long-term systemic steroid use on electrical and mechanical complications following ST-segment elevation myocardial infarction (STEMI) has not been extensively studied. Methods In a retrospective cohort study of the National Inpatient Sample (NIS) from 2018 to 2020, adults admitted with STEMI were dichotomized based on the presence of long-term (current) systemic steroid (LTCSS) use. The primary outcome was all-cause mortality. Secondary outcomes included a composite of mechanical complications, electrical, hemodynamic, and thrombotic complications, as well as revascularization complexity, length of stay (LOS), and total charge...

Low-dose prasugrel demonstrated a similar effectiveness profile to clopidogrel in East Asian ACS patients, but its comparison with another new-generation potent P2Y12 inhibitor, ticagrelor, remains unclear. To compare the effectiveness and safety of low-dose prasugrel against those of standard-dose ticagrelor in East Asian patients with ACS. This retrospective cohort study used Taiwan's National Health and Welfare Database. This study included ACS patients who underwent percutaneous coronary intervention and, at discharge between January 1, 2018 and December 31, 2020, were prescribed with low-dose prasugrel plus aspirin or standard-dose ticagrelor plus aspirin...

BACKGROUND: Acute myocardial infarction is associated with the release of the co-transmitter neuropeptide-Y (NPY). NPY acts as a potent vasoconstrictor and is associated with microvascular dysfunction after ST-elevation myocardial infarction (STEMI). This study comprehensively evaluated the association of plasma NPY with myocardial function and infarct severity, visualized by cardiac magnetic resonance (CMR) imaging, in STEMI patients revascularized by primary percutaneous coronary intervention (PCI)...

BACKGROUND: The role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) who subsequently undergo transcatheter aortic valve replacement (TAVR) remains uncertain. Therefore, we conducted this study to assess the association of PCI before TAVR with mortality and cardiovascular outcomes. METHODS: We used the TriNetX database (Jan 2012 - Aug 2022) and grouped patients into PCI (3 months or less) before TAVR and no PCI...

BACKGROUND: Limited data are available regarding myocardial injury and its risk factors in percutaneous coronary interventions (PCI) of severe calcified lesions using orbital atherectomy (OA). METHODS: Patients who underwent OA at our institution were retrospectively enrolled into the present registry. High-sensitive Troponin I (hsTroponin I), EKG and echocardiography were used to assess myocardial injury after the procedure. RESULTS: A total of 27 patients between who underwent OA between January 2022 and June 2023 were included...

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome in young patients. Supportive care is recommended for most uncomplicated cases. However, it is unclear if revascularization plays a role in treating SCAD, particularly in the setting of cardiogenic shock. We present a case of a 40-year-old female with no past medical history admitted for SCAD that was complicated by the Society for Cardiovascular Angiography & Interventions (SCAI) stage D cardiogenic shock. She was successfully managed with a percutaneous left ventricular assist device without revascularization...

Ischemic cardiomyopathy (ICM) is the most common underlying etiology of heart failure in the United States and is a significant contributor to deaths due to cardiovascular disease worldwide. The diagnosis and management of ICM has advanced significantly over the past few decades, and the evidence for medical therapy in ICM is both compelling and robust. This contrasts with evidence for coronary revascularization, which is more controversial and favors surgical approaches. This review will examine landmark clinical trial results in detail as well as provide a comprehensive overview of the current epidemiology, diagnostic approaches, and management strategies of ICM...

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is recommended for at least 6 and 12 months following percutaneous coronary intervention with drug-eluting stents among patients with stable ischemic heart disease and acute coronary syndrome, respectively. Additional exposure to antiplatelet therapy reduces ischemic events but also increases bleeding risk. Conversely, shorter durations of DAPT are preferred among those at high bleeding risk. Hence, decisions surrounding duration of DAPT after revascularization should include clinical judgment, assessment of the risk of bleeding and ischemic events, and time after revascularization...

Revascularization is an effective adjunct to medical therapy for some patients with chronic coronary disease. Despite numerous randomized trials, there remains significant uncertainty regarding if and how to revascularize many patients. Coronary artery bypass grafting is a class I indication for patients with significant left main stenosis or multivessel disease with ejection fraction ≤ 35%. For other patients, clinicians must carefully consider the potential benefits of symptom improvement and reduction of future myocardial infarction or CV death against the risk and cost of revascularization...

BACKGROUND: The value of counting inflammatory cells and especially their counting ratio in predicting adverse clinical outcomes in patients with acute coronary syndrome (ACS) undergoing revascularization has been shown, but the results of studies have been very diverse and paradoxical. The aim of the current study was to systematically review the studies that investigated the role of increased neutrophil-to-lymphocyte ratio (NLR) in predicting long-term clinical outcomes in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI)...

BACKGROUND: Complete revascularization of the culprit and all significant nonculprit lesions in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and multivessel disease (MVD) reduces major adverse cardiac events, but optimal timing of revascularization remains unclear. OBJECTIVES: This study aims to compare immediate complete revascularization (ICR) and staged complete revascularization (SCR) in patients presenting with NSTE-ACS and MVD...

BACKGROUND: Percutaneous coronary intervention (PCI) for bifurcation lesions still represents a clinical challenge. The Bioss Lim C is a dedicated device for bifurcation lesions, features a tapered shape and large cells, and thus appears as a promising adjunct to the current interventional cardiologists' armamentarium. We aimed at conducting a prospective multicenter study focusing on early and long-term results after Bioss Lim C implantation for true coronary bifurcation lesions. METHODS: Patients with true bifurcation lesions in whom Bioss Lim C implantation was attempted were enrolled in four Italian centers...

BACKGROUND: The risk of coronary artery disease is exaggerated in patients with autoimmune diseases (AID). A higher risk of complications has been reported during and after percutaneous coronary intervention (PCI) in these patients. We aimed to analyze the in-hospital outcomes and trends of patients with AID, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD) undergoing PCI. METHOD: We identified all PCI procedures using the National In-patient Sample database from 2016 to 2020...

We present a case of a patient with inferior myocardial infarction (MI) and anomalous left main artery originating from the right coronary sinus. The left main artery and right coronary artery originated from the right coronary sinus but with separate ostia. The patient underwent revascularization of the right coronary artery with balloon angioplasty and a drug-eluting stent. Despite being rare, these anomalies can be life-threatening depending on the course of the artery, and when atherosclerotic disease is present, a revascularization strategy can be challenging...
