Intra-aortic balloon pump (IABP) is commonly used as mechanical support after cardiac surgery or cardiac shock. Although its benefits for cardiac function have been well documented, its effects on cerebral circulation are still controversial. We hypothesized that transfer function analysis (TFA) and continuous estimates of dynamic cerebral autoregulation (CA) provide consistent results in the assessment of cerebral autoregulation in patients with IABP. Continuous recordings of blood pressure (BP, intra-arterial line), end-tidal CO2, heart rate and cerebral blood flow velocity (CBFV, transcranial Doppler) were obtained i) 5 minutes with IABP ratio 1:3, ii) 5 minutes, starting 1 minute with the IABP-ON, and continuing for another 4 minutes without pump assistance (IABP-OFF)...

OBJECTIVES: This retrospective, single-center, observational analysis from prospectively collected database evaluated whether left dominance affected the long-term outcomes of acute coronary syndrome patients undergoing percutaneous coronary intervention, and whether the effect was independent of SYNTAX score. BACKGROUND: Left dominance is believed to be associated with worse prognoses. The anatomical SYNTAX score is a scoring system based on the complexity and severity of coronary lesions and is thought to be a prognostic tool to predict short- and long-term outcomes...

OBJECTIVE: To determine the ability of simple hemodynamic parameters obtained at the time of cardiac catheterization to predict in-hospital mortality following ST-elevation myocardial infarction (STEMI). BACKGROUND: Hemodynamic parameters measured at the time of primary percutaneous coronary intervention (PPCI) could potentially identify high-risk patients who would benefit from aggressive hemodynamic support in the Cardiac Catheterization laboratory. METHODS: This is a retrospective single-center study of 219 consecutive patients with STEMI...

CONTEXT: Both invasive and noninvasive blood pressure (invasive arterial blood pressure [IABP] and noninvasive BP [NIBP]) monitors are used perioperatively; however, they often produce different values. The reason for this discrepancy is not clear, and it is possible that the act of cuff inflation itself might affect the IABP values, especially with the recurrent cycling of NIBP cuff. AIM: The aim of this study was to determine the effect of ipsilateral NIBP cuff inflation on the contralateral IABP values...

Cardiogenic shock in the context of acute ST-elevation myocardial infarction (STEMI) remains a challenge to manage and results in significant mortality and morbidity, cardiac arrest in this setting even more so. The increase in myocardial oxygen demand and consumption with the use of inotropes is recognised as increasing mortality. Alternatives include the intra-aortic balloon pump (IABP), which has yet to be shown to improve outcomes, and extracorporeal membrane oxygenation (ECMO), which requires super-specialised techniques not widely available...

AIMS: Prophylactic intra-aortic balloon pump (IABP) support for high-risk patients before coronary artery bypass grafting (CABG) is controversial. This meta-analysis sought to determine the current role of preoperative IABP support. METHODS: We performed a meta-analysis of randomized (RCT) and observational trials (OT) that fulfilled the following criteria: (1) Group comparison of patients with prophylactic IABP implantation before CABG with a control group; (2) reporting at least one desired clinical endpoint, including all-cause mortality, myocardial infarction, cerebrovascular accident (CVA), and renal failure...

Coronary artery disease (CAD) represents a common structural cause for developing cardiac arrest in older patients, whereas in young adults cardiac arrest is more often caused by cardiomyopathies and cardiac channelopathies. A structural heart disease is known in almost 50% of patients prior to cardiac arrest. The present review outlines current interventional and operative therapeutic options for patients surviving cardiac arrest. The focus is on associations between epidemiological data on the incidence of malignant arrhythmias causing cardiac arrest depending on the presence or absence of CAD...

We report on a 69-year-old woman who demonstrated native coronary artery and grafted vessel spasm following on-pump coronary artery bypass grafting (CABG). Despite intraaortic balloon pump (IABP) insertion, electrocardiogram (ECG) abnormalities did not disappear. Emergency coronary angiography (CAG) was performed. The patient was successfully treated with systemic and intracoronary injection of vasodilator agents. ECG changes disappeared, with normalized and stable hemodynamic function. Intraaortic balloon pump was maintained for 48 h...

A 90-year-old female with severe peripheral vascular disease developed cardiogenic shock (CS) due to critical aortic stenosis (AS). The balloon aortic valvuloplasty was emergently performed via transvenous and transseptal antegrade approach (ante-BAV), which saved arterial accesses for intra-aortic balloon pump (IABP) and enabled us to use the Inoue balloon. The IABP augmented systemic perfusions and controlled left heart filling pressures. Multiple times of inflations with stepwisely increased balloon diameters were performed under IABP support (ante-Inoue-BAV + IABP), resulting in remarkable improvements both in clinical and hemodynamic conditions...

Acute left ventricular dysfunction in children justifies aggressive treatment because of the high potential for complete recovery. The options for providing mechanical support to the failing heart in a child include extracorporeal membrane oxygenation, left ventricular assist devices, and the use of the intra-aortic balloon pump (IABP). The IABP is a commonly used method of temporary circulatory support in adults. However, despite the availability of pediatric size balloons, the usage of IABP for temporary circulatory support in children has not been widespread...

RATIONALE: Severe left main disease combined with right coronary artery occlusion was rarely encountered in our daily practice. Percutaneous coronary intervention in these patients was most challenging due to high probability of hemodynamic changes. PATIENT CONCERNS: Here, we report a 67-year-old man with Non-ST-Segment Elevation Myocardial Infarction (NSTEMI) and profound cardiogenic shock and we attempted coronary intervention with total revisualization for severe left main (LM) disease and angulated epsilon right coronary artery total occlusion...

Critical illness associated with cardiac pump failure results in reduced tissue perfusion in all organs and occurs in various conditions such as sepsis, cardiogenic shock, and heart failure. Mechanical circulatory support (MCS) devices can be used to maintain organ perfusion in patients with cardiogenic shock and decompensated chronic heart failure. However, correction of global hemodynamic parameters by MCS does not always cause a parallel improvement in microcirculatory perfusion and oxygenation of the organ systems, a condition referred to as a loss of hemodynamic coherence between macro- and microcirculation (MC)...

BACKGROUND: Despite the improvement of therapeutic options for patients in acute myocardial infarction (AMI), cardiogenic shock (CS) remains a complication with high mortality rates. Organ failure centrally determines the prognosis of these high-risk patients. Aim of the current study was to assess the incidence of hypoxic hepatitis (HH) in CS, its laboratory detection evaluating novel and established biomarkers and to estimate the prognostic relevance of HH in current clinical practice...

BACKGROUND: Catalytic iron (CI) is unbound ferric iron with the potential to generate reactive oxygen species with further deleterious vascular effects. In acute coronary syndromes, high levels of CI are linked to all-cause mortality. The prognostic impact of CI and iron metabolism in cardiogenic shock (CS) is currently undetermined. Aims of this study were to investigate the prognostic impact of CI and to identify predictors of high CI levels in patients with CS complicating acute myocardial infarction...
