BACKGROUND: Recent trends on outcomes in cardiogenic shock (CS) complicating acute myocardial infarction (AMI) suggest improvements in early survival. However, with the ever-changing landscape in management of CS, we sought to identify age-based trends in these outcomes and mechanical circulatory support (MCS) use among patients with both AMI and non-AMI associated shock. METHODS: We queried the 2005-2014 Nationwide Inpatient Sample databases to identify patients with a diagnosis of cardiogenic shock...

BACKGROUND: Aim of the current study was to analyse the impact of atrial fibrillation (AF) on prognosis in patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI), which has never been investigated yet. METHODS: The current analysis is a substudy of the IABP-SHOCK II trial. Patients were grouped according to the presence or absence of AF. The primary endpoint was all-cause mortality at 30-day follow-up. Secondary endpoints included all-cause mortality, recurrent myocardial infarction, repeat revascularisation, and stroke at 12 months...

Cases: Septic cardiomyopathy is defined as a reversible left ventricular systolic dysfunction. Patients with severe septic cardiomyopathy have a high mortality rate, even if they receive conventional therapy. For those patients, previous reports showed intra-aortic balloon pump (IABP) efficacy. We report two rare cases with IABP introduction leading them to drastic improvement, and survival from severe septic cardiomyopathy. Case 1 is a 78-year-old woman diagnosed with renal calculus pyelonephritis, septic shock, and septic cardiomyopathy...

We aimed to evaluate the timing of preoperative intra-aortic balloon pump (IABP) placement and outcomes in patients undergoing off-pump coronary artery bypass grafting (OPCAB). Patients with prophylactic IABP placement before OPCAB presenting between January 1, 2010 and December 31, 2013 were included. Patients were categorized into two groups based on the timing of preoperative IABP placement: less than 2 h (Group A, n = 223) and more than 2 h (Group B, n = 94). According to the European System for Cardiac Operative Risk Evaluation (EuroSCORE), patients were divided into two subgroups: middle-low EuroSCORE (<6, Groups A1 and B1) and high EuroSCORE (≥6, Groups A2 and B2)...

Intra-aortic balloon pump (IABP) is normally contraindicated in significant aortic regurgitation (AR). It causes and aggravates pre-existing AR while performing well in the event of mitral regurgitation (MR). Indirect parameters, such as the mean systolic pressure, product of heart rate and peak systolic pressure, and pressure-volume are used to quantify the effect of IABP on ventricular workload. However, to date, no studies have directly quantified the reduction in workload with IABP. The goal of this study is to examine the effect of IABP therapy on ventricular mechanics under valvular insufficiency by using a computational model of the heart...

Aims: Evidence on the impact on clinical outcome of active mechanical circulatory support (MCS) devices in cardiogenic shock (CS) is scarce. This collaborative meta-analysis of randomized trials thus aims to investigate the efficacy and safety of percutanzeous active MCS vs. control in CS. Methods and results: Randomized trials comparing percutaneous active MCS to control in patients with CS were identified through searches of medical literature databases. Risk ratios (RR) and 95% confidence intervals (95% CI) were calculated to analyse the primary endpoint of 30-day mortality and device-related complications including bleeding and leg ischaemia...

The intra-aortic balloon pump (IABP) has been the most commonly used mechanical circulatory support device for nearly five decades. In theory, the IABP can increase the blood and oxygen supply of the coronary artery by increasing the diastolic pressure in the aortic root when the balloon is inflated and reduce left ventricular afterload by rapidly deflating the balloon during the systolic phase. Therefore, some researchers put forward the idea of preoperative prophylactic use of an IABP, which has been frequently performed in high-risk patients undergoing elective percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG)...

This CME article addresses the pathophysiology, incidence, current survival outcome and treatment options for patients with cardiogenic shock as a complication of acute myocardial infarction. The shock spiral of left heart failure due to cardiac infarction, subsequent vasoconstriction and paradoxical vasodilation due to the systemic inflammation response syndrome (SIRS) is a vicious circle which must be interrupted. Treatment focuses on the evidence from randomized clinical trials and the current guideline recommendations...

Percutaneous transfemoral transcatheter aortic valve implantation (TF-TAVI) is generally an acceptable procedure but may be associated with vascular complications at femoral access sites, particularly in obese patients. This report aimed to describe a case of successful performance of our "double crossover technique" in an obese patient undergoing TF-TAVI with a percutaneous transfemoral intra-aortic balloon pump (TF-IABP). A 75-year-old man presented with heart failure due to a left ventricular ejection fraction of 35% and low-flow, low-gradient severe aortic stenosis...

BACKGROUND: Small randomized controlled trials (RCTs) and observational studies have examined the effectiveness and safety of the Impella device, a percutaneous left ventricular assist device, in the setting of high-risk percutaneous coronary intervention (PCI). However, data are sparse and results are conflicting. Our objective was to evaluate the effectiveness and safety of the Impella device in high-risk patients undergoing PCI via a systematic review of the literature. METHODS: We searched Medline, EMBASE, and the Cochrane Library for RCTs and observational studies that evaluated the Impella device in high-risk patients undergoing PCI...

Cardiac failure may occur after repair of type A aortic dissections and contributes significantly to mortality. The use of an intraaortic balloon pump (IABP) for circulatory support in these patients is traditionally considered contraindicated because of concerns over extension of the residual dissection flap or aortic rupture. We propose that the use of an IABP may be appropriate and safe to improve cardiac function in patients after type A dissection repair. The two cases presented here contribute to increasing the body of evidence to support the appropriate use of IABP in these patients...

BACKGROUND: Despite widespread use, evidence to support preemptive intraaortic balloon pump (IABP) insertion for patients undergoing high-risk coronary artery bypass graft (CABG) surgery remains sparse, and in need of a well-defined clinical trial. To inform the design of a prospective trial, we sought to review outcomes in randomized controlled trials (RCTs) of anticipatory IABP use vs control in patients undergoing high-risk CABG through meta-analysis. The primary endpoint was all-cause mortality within 30 days of surgery...

The clinical results of patients with acute myocardial infarction (AMI) at the left main trunk (LMT) remain unclear, especially in cases requiring percutaneous cardiopulmonary support (PCPS). Twenty seven cases of AMI at the LMT requiring emergent PCPS were retrospectively investigated. These 27 patients were aged 44-83 years (65.6 ± 8.6 years) and 20 (81.5%) were men. Peak creatine kinase (CK) leakage ranged from 538 to 34,010 IU/l (13,553 ± 7656 IU/l). Eight (29.6%) patients were discharged without mechanical support...

BACKGROUND: Acute kidney injury (AKI) and its severity after transcatheter aortic valve replacement (TAVR) have been associated with worse outcomes. Studies have shown that AKI duration (transient or persistent) affects outcomes independently of AKI severity. This study was undertaken to determine the association, risk factors, and outcomes associated with persistent AKI (pAKI) after TAVR. METHODS: Adult patients undergoing TAVR at Mayo Clinic between January 1, 2008 and June 30, 2014 were enrolled...

INTRODUCTION: Intra-aortic balloon pump (IABP) counterpulsation is a catheter-based treatment for coronary artery disease and decompensated heart failure to increase coronary blood flow and improve cardiac output. IABP is generally well tolerated, and complications are usually related to peripheral vasculature or red blood cell and platelet consumption. The usual insertion site via femoral artery renders the patient bedbound. Recently, axillary artery has been used in patients with atherosclerotic peripheral vascular disease and documented small arteries or in those awaiting transplant to ensure ambulation and prevent deconditioning...

BACKGROUND: The use of the intra-aortic balloon pump (IABP) as a support device remains controversial due to the fact that a number of studies have shown no benefit in end mortality whilst using this device. One of the reasons for this could be the increase in vascular complications when using the pump. Therefore, the aim of the present review was to assess the current literature available with regards to IABP vascular complications during the clinical situation. METHODS: A literature search was performed, searching for IABP complications in adult human studies between 1990 and 2016...
