The aim of this study was to evaluate the accuracy and feasibility of real-time 3-D echocardiography (3-DE) in assessing right ventricular (RV) systolic function. A latex balloon was inserted into the right ventricle of 20 freshly harvested pig hearts which were then passively driven by a pulsatile pump apparatus. The RV global longitudinal strain (GLS), global circumferential strain (GCS), global area strain (GAS) and RV ejection fraction (RVEF), derived from 3-DE, as well as the RVEF obtained from 2-D echocardiography (2-DE) were quantified at different stroke volumes (30-70 mL) and compared with sonomicrometry data...

BACKGROUND: Postcardiotomy cardiogenic shock (PCCS) refractory to inotropic support and intra-aortic balloon pump (IABP) occurs rarely but is almost universally fatal without mechanical circulatory support. In this systematic review and meta-analysis we looked at the evidence behind the use of veno-arterial extra-corporeal membrane oxygenation (VA ECMO) in refractory PCCS from a patient survival rate and determinants of outcome viewpoint. METHODS: A systematic review was performed in January 2017 using PubMed (with no defined time period) using the keywords "postcardiotomy", "cardiogenic shock", "extracorporeal membrane oxygenation" and "cardiac surgery"...

BACKGROUND: Femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) is widely used to maintain blood flow in patients with cardiogenic shock. However, retrograde blood flow increases left ventricular (LV) afterload during femoral VA-ECMO. Additional support by means of an intraaortic balloon pump (IABP) alleviates LV afterload but is associated with significant adverse events. We previously developed a system for rotational speed modulation in synchrony with the native cardiac cycle, for use with implantable continuous-flow LV assist devices...

A 73-year-old male was brought into hospital with chest pain and inferior ST elevation on ECG. He immediately proceeded to the catheter lab for primary percutaneous coronary intervention. Angiography did not identify any culprit lesions to account for the patient's electrocardiographic changes and ongoing symptoms of chest pain. Bedside echocardiography revealed critical aortic stenosis. Intra-aortic balloon pump was inserted resulting in resolution of chest pain and ST-segment changes. The patient underwent successful aortic valve replacement without the need for coronary intervention...

Mechanical assistance of systemic single ventricle is effective in pulling blood through a cavopulmonary circuit. In patients with superior cavopulmonary connection, this strategy can lead to arterial desaturation secondary to increased inferior caval flow. We hypothesized that overall augmentation in cardiac output with mechanical assistance compensates for the drop in oxygen saturation thereby maintaining tissue oxygen delivery (DO2). Bidirectional Glenn (BDG) was established in seven swine (25 kg) after a common atrium had been established by balloon septostomy...

Temporary mechanical circulatory support is increasingly used, particularly in patients with cardiogenic shock or during high-risk percutaneous coronary interventions. In the last five years there have been numerous developments in this field. Experience has been gained from usage of temporary heart pumps, and new pumps have arrived on the market. Until recently, the intra-aortal balloon pump was the standard treatment for patients with cardiogenic shock; however, results from the latest research into the effectiveness of this pump have rendered it less popular...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

Post-myocardial infarction ventricular septal defect corresponds to the rupture of the ventricular septum between the healthy and infarcted parts. It is a rare complication still associated with a high mortality rate. Its diagnostic should be evoked in case of pathologic cardiac auscultation and confirmed by emergent transthoracic echocardiography. Hemodynamic stabilisation, mainly with the insertion of an intra-aortic balloon pump is the first step in the management. The subsequent modality of closure, either surgical or transcatheter, as well as the ideal timing should be discussed in the Heart team...

Blood oxygenized by veno-arterial extracorporeal membrane oxygenation (ECMO) can be returned to the aorta (central cannulation) or to peripheral arteries (axillar, femoral). Hemodynamic effects of these cannulation types were analyzed in a mock loop with an aortic model representative of normal anatomy and compliance under physiological pressures and flow rates. Pressures, flow rates, and contribution of ECMO flow to total flow as a measure of oxygen supply were monitored in the carotids. Steady or pulsatile ECMO flow, residual or no cardiac output, and intraaortic balloon pump counterpulsation were tested as independent factors...
