Strategies for Reducing Vascular and Bleeding Risk for Percutaneous Left Ventricular Assist Device-supported High-risk Percutaneous Coronary Intervention.

In patients at high risk for haemodynamic instability during percutaneous coronary intervention (PCI), practitioners are increasingly opting for prophylactic mechanical circulatory support, such as the Impella® heart pump (Abiomed, Danvers, MA, USA). Though Impella-supported high-risk PCI (HRPCI) ensures haemodynamic stability during the PCI procedure, access-related complication rates have varied significantly in published studies. Reported variability in complication rates relates to many factors, including anticoagulation practices, access and closure strategy, post-procedure care and variations in event definitions.

A Review of Bleeding Risk with Impella-supported High-risk Percutaneous Coronary Intervention.

Complex, high-risk percutaneous coronary intervention (HR-PCI) is increasingly being performed, often with mechanical circulatory support (MCS), though to date, there are limited randomised data on the efficacy of MCS for HR-PCI. The majority of MCS is provided by intra-aortic balloon pumps, but increasingly Impella® (Abiomed, Danvers, MA, USA) heart pumps are being used. While the Impella pumps provide greater increases in cardiac output, these devices require large bore access, which has been associated with an increased risk of bleeding and vascular complications.

Cost savings for pVAD compared to ECMO in the management of acute myocardial infarction complicated by cardiogenic shock: An episode-of-care analysis.

Background: Acute myocardial infarction complicated by cardiogenic shock (AMICS) occurs in up to 10% of acute myocardial infarction admissions and is associated with high mortality, frequent adverse outcomes, prolonged hospitalizations, extensive medical resource utilization, and major cost. Using hospital cost data for Medicare Fee-for-Service (FFS) patients with AMICS, we sought to evaluate in hospital and 45-day outcomes and cost, comparing patients treated with percutaneous ventricular assist device (pVAD) versus extracorporeal membrane oxygenation (ECMO). The goal of this study was to better understand clinical and economic outcomes of AMICS to help clinicians and hospitals optimize outcomes most economically for AMICS patients.

Comparison of In-Hospital Outcomes in Patients Having Limb-Revascularization With Versus Without Atrial Fibrillation.

The impact of atrial fibrillation (AF) on clinical outcomes among patients with peripheral artery disease (PAD) who undergo limb revascularization procedures is not well understood. We aim to compare in-hospital outcomes for patients with and without AF who underwent limb revascularization. We identified patients with PAD aged ≥18 years that underwent limb revascularization using endovascular or surgical approaches in the National Inpatient Sample between 2002 and 2014.

Expanding opportunities for stent optimization.

Restenosis is reduced but continues to impact optimal late PCI outcomes. FFR post stenting can predict late need for repeat revascularization. Intraluminal Intensity of Blood Speckle measured via Intravascular Ultrasound may provide another method to predict target vessel revascularization.

Stent "Hygiene".

Studies demonstrate ideal Stent expansion with prolonged inflations. Longer inflations, a mediator of greater stent expansion, lower immediate, subacute, and late stent failure. Research should focus on components of stent deployment that optimize early and late stent outcomes.

A comprehensive meta-analysis of randomized controlled trials comparing drug-eluting stents with bare-metal stents in saphenous vein graft interventions.

Background: Several large randomized controlled trials (RCTs) have proven the superiority of drug-eluting stents (DESs) over bare-metal stents (BMSs) for native coronary stenosis. However, RCTs comparing DESs with BMSs for SVG lesions have predominantly been small in size and have yielded conflicting results. Therefore, we conducted an updated comprehensive meta-analysis of RCTs comparing DESs versus BMSs for SVG interventions using the largest sample size to date.

The cVAD registry for percutaneous temporary hemodynamic support: A prospective registry of Impella mechanical circulatory support use in high-risk PCI, cardiogenic shock, and decompensated heart failure.

Unlabelled: Management of patients requiring temporary, mechanical hemodynamic support during high- risk percutaneous coronary intervention (PCI) or in cardiogenic shock is rapidly evolving. With the availability of the Impella 2.5, CP, 5.

One-Year Clinical Effectiveness Comparison of Prasugrel with Ticagrelor: Results from a Retrospective Observational Study using an Integrated Claims Database.

Background: No direct comparisons of ticagrelor and prasugrel with 1-year clinical follow-up have been reported.

Objectives: Our objective was to compare 1-year clinical outcomes among patients with acute coronary syndrome (ACS) managed with percutaneous coronary intervention (PCI) and treated with either ticagrelor or prasugrel in a real-world setting.

Methods: This retrospective study included patients from a payer database who were aged ≥18 years and had ACS managed with PCI with no history of transient ischemic attack (TIA)/stroke.

Hemodynamic Support Devices for Shock and High-Risk PCI: When and Which One.

Purpose Of Review: This article addresses evolving devices and uses of hemodynamic support in the management of high-risk PCI and AMI with cardiogenic shock.

Recent Findings: Recent publications question the benefit of Intra-aortic Balloon Pump support for AMI Shock. Furthermore, in high-risk PCI, the Impella support system provides better late outcomes than does the intra-aortic balloon pump.

Meta-Analysis Comparing Coronary Artery Bypass Grafting to Drug-Eluting Stents and to Medical Therapy Alone for Left Main Coronary Artery Disease.

Historically, coronary artery bypass graft (CABG) surgery has been the standard revascularization method for unprotected left main coronary artery (LMCA) disease. Over the last decade, several randomized controlled trials (RCTs) have shown favorable results for percutaneous coronary intervention (PCI) with drug-eluting stent (DES) compared with CABG; however, no RCT has been conducted directly comparing DESs with medical therapy alone (MTA). Furthermore, the 2 most recently reported larger RCTs, using new-generation DESs reached somewhat conflicting conclusions comparing the 2 revascularization strategies.

Outcomes in Patients Undergoing Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction Via Radial Access Anticoagulated With Bivalirudin Versus Heparin: A Report From the National Cardiovascular Data Registry.

Objectives: The aim of this study was to compare bivalirudin with heparin as anticoagulant agents in patients with ST-segment elevation myocardial infarction treated with radial primary percutaneous coronary intervention (PCI).

Background: Recent studies in which PCI was performed predominantly via radial access did not show bivalirudin to be superior to heparin.

Methods: Outcomes were compared in patients with STEMI included in the National Cardiovascular Data Registry CathPCI database from 2009 to 2015 who underwent primary PCI via radial access and who were anticoagulated with bivalirudin or heparin.
