Estimation of Systolic and Diastolic Left Ventricular Blood Flow From Derivatives of Transesophageal Echocardiographic 3D Volume Curves in Cardiac Surgery Patients: A Proof-of-Concept Study.

Objectives: To examine whether estimates of peak global systolic (S') and diastolic (E') left ventricular (LV) flow rates based on 3D echocardiographic volumes are feasible and match physiology.

Methods: In this retrospective feasibility study, we included patients undergoing major cardiac surgery. S' and E' were derived from 190 patients by taking the first derivative of the volume-time relationship of 3D ecg-gated transesophageal echocardiography (TEE) images.

Pressure-Volume Loops for Reviewing Right Ventricular Physiology and Failure in the Context of Left Ventricular Assist Device Implantation.

Right ventricular (RV) function is complex as a number of determinants beyond preload, inotropy and afterload play a fundamental role. In particular, arterial elastance (E), ventriculo-arterial coupling (VAC), and (systolic) ventricular interdependence play a vital role for the right ventricle. Understanding and actively visualizing these interactions in the failing RV as well as in the altered hemodynamic and morphological situation of left ventricular assist device (LVAD) implantation may aid clinicians in their understanding of RV dysfunction and failure.

Influence of timing of Levosimendan administration on outcomes in cardiac surgery.

Purpose: Though a subgroup analysis has shown improved survival for patients suffering severely reduced ventricular function undergoing coronary artery bypass grafting, RCTs were not able to demonstrate overall beneficial effects of perioperative Levosimendan in cardiac surgery. This might be due to Levosimendan's pharmacokinetics reaching a steady-state concentration only 4-8 h after administration. Thus, this study now analysed the influence of timing of Levosimendan administration on perioperative outcome in cardiac surgery patients preoperatively presenting with severely reduced ventricular function and therefore considered at high-risk for intra- or postoperative low cardiac output syndrome.

Perioperative Doppler ultrasound assessment of portal vein flow pulsatility in high-risk cardiac surgery patients: a multicentre prospective cohort study.

Background: Portal vein Doppler ultrasound pulsatility measured by transoesophageal echocardiography is a marker of the haemodynamic impact of venous congestion in cardiac surgery. We investigated whether the presence of abnormal portal vein flow pulsatility is associated with a longer duration of invasive life support and postoperative complications in high-risk patients.

Methods: In this multicentre cohort study, pulsed-wave Doppler ultrasound assessments of portal vein flow were performed during anaesthesia before initiation of cardiopulmonary bypass (before CPB) and after separation of cardiopulmonary bypass (after CPB).

Pediatric cardiac anesthesia is a subspecialty of cardiac and pediatric anesthesiology dedicated to the perioperative care of patients with congenital heart disease. Members of the Congenital and Education Subcommittees of the European Association of Cardiothoracic Anaesthesiology and Intensive Care (EACTAIC) agreed on the necessity to develop an EACTAIC pediatric cardiac anesthesia fellowship curriculum. This manuscript represents a consensus on the composition and the design of the EACTAIC Pediatric Cardiac Anesthesia Fellowship program.

5-year results of a newly implemented mechanical circulatory support program for terminal heart failure patients in a Swiss non-cardiac transplant university hospital.

Background: In Switzerland, long-term circulatory support programs have been limited to heart transplant centers. In 2014, to improve the management of patients with end-stage heart failure not eligible for transplantation, we implemented a left ventricular assist device (LVAD) program for destination therapy at the University Hospital of Basel.

Methods: We described the program set-up with practical aspects.

Controversies in the Clinical Practice of Patient Blood Management.

Patient blood management (PBM) has been proposed as a standard of care in modern perioperative medicine. PBM-related interventions usually are implemented as bundles, but randomized controlled trials on the implementation of PBM as a bundle are missing. This special article focuses on the current evidence and controversies in the clinical practice of PBM and on emerging data related to specific PBM-related interventions in patients undergoing cardiac surgery.

Current Anesthetic Care of Patients Undergoing Transcatheter Aortic Valve Replacement in Europe: Results of an Online Survey.

Objectives: Transcatheter aortic valve replacement (TAVR) has become an alternative treatment for patients with symptomatic aortic stenosis not eligible for surgical valve replacement due to a high periprocedural risk or comorbidities. However, there are several areas of debate concerning the pre-, intra- and post-procedural management. The standards and management for these topics may vary widely among different institutions and countries in Europe.

Echocardiographic and Clinical Follow-up After Aortic Valve Neocuspidization Using Autologous Pericardium.

Introduction: Mid-term data from a single centre showed the safety and durability of aortic valve neocuspidization using autologous pericardium (OZAKI procedure). Since validation data from other centres are missing, aim of this study was to analyze echocardiographic and clinical results of our first patients that were operated with the OZAKI technique.

Methods: Thirty-five patients (24 males, median (IQR) age 72.

European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia Fellowship Curriculum: First Edition.

This special article summarizes the design and certification process of the European Association of Cardiothoracic Anesthesiology (EACTA) Cardiothoracic and Vascular Anesthesia (CTVA) Fellowship Program. The CTVA fellowship training includes a two-year curriculum at an EACTA-accredited educational facility. Before fellows are accepted into the program, they must meet a number of requirements, including evidence of a valid license to practice medicine, a specialist degree examination in anesthesiology, and appropriate language skills as required in the host centers.

Perspectives on the Fellowship Training in Cardiac, Thoracic, and Vascular Anesthesia and Critical Care in Europe From Program Directors and Educational Leads Around Europe.

This article reviews fellowship training in adult cardiac, thoracic, and vascular anesthesia and critical care from the perspective of European program initiators and educational leaders in these subspecialties together with current training fellows. Currently, the European Association of Cardiothoracic Anaesthesiology (EACTA) network has 20 certified fellowship positions each year in 10 hosting centers within 7 European countries, with 2 positions outside Europe (São Paulo, Brazil). Since 2009, 42 fellows have completed the fellowship training.

Thoracoscopic epicardial left ventricular bipolar lead implantation with the use of automated titanium fasteners (Cor-Knot®).

Background: Pacemaker implantation techniques using thoracoscopy have been described since about 25 years. However, the published reports concerning types of electrodes refer mostly to monopolar screw-in leads. We report our experience of thoracoscopic implantation of a bipolar suture-on epicardial electrode with monofilamentous sutures tightened by automated fasteners to avoid hand-tied knots.

Utilization of echocardiography in Intensive Care Units: results of an online survey in Germany.

Background: In patients with hemodynamic instability echocardiography has been recommended as the preferred modality to evaluate the underlying pathophysiology. However, due to the fact that recent scientific data on the utilization of echocardiography in German Intensive Care Units (ICU) are scarce, we sought to investigate current practice.

Methods: A structured, web-based, anonymized survey was performed from May until July 2015 among members of the German Interdisciplinary Association of Critical Care and Emergency Medicine (DIVI) consisting of 14 questions.

Fluid Management in Cardiac Surgery: Results of a Survey in European Cardiac Anesthesia Departments.

Objective: To evaluate the current practice of perioperative fluid management in cardiac surgery patients.

Design: Multiple choice survey with 26 questions about existing practice of perioperative fluid management in cardiac surgery patients.

Setting: Online survey.

Early levosimendan administration is associated with decreased mortality after cardiac surgery.

Purpose: The aim of this study was to assess the effects on postoperative outcome of levosimendan with respect to timing of its administration in cardiac surgery patients.

Materials And Methods: Levosimendan administration was triggered by a severely reduced left ventricular systolic function (left ventricular ejection fraction, <35%) and/or signs of a low cardiac output syndrome. A total of 159 patients were retrospectively assigned depending on an early (perioperatively up to the first hour after intensive care unit [ICU] admission) vs late (later than the first hour after ICU admission) start of treatment.

["Introduction to transthoracic, transesophageal and real time 3Dimensional transesophageal echocardiography"].

Echocardiography allows assessment of cardiac anatomy and function. A tailored approach to echocardiographic assessment is essential in hemodynamic unstable patients. Standard views allow comprehensive examination and also reduce the chances to oversee unexpected findings.

Influence of levosimendan on organ dysfunction in patients with severely reduced left ventricular function undergoing cardiac surgery.

Objectives: Levosimendan is an inotropic drug with organ-protective properties due to its activation of mitochondrial K(ATP) channels. This prospective, randomized, double-blind, placebo-controlled study investigated whether administration of levosimendan prior to cardiopulmonary bypass could reduce organ dysfunction and influence subsequent secondary endpoints.

Patients And Methods: Patients with left ventricular ejection fraction <30% scheduled for elective coronary artery bypass surgery (with or without valve surgery) received either levosimendan (12.

[DGAI-certified seminar series: anaesthesia focussed echocardiography: module 4 cardiosonography].

The use of ultrasonography in perioperative medicine has developed rapidly within the last decade. Today ultrasonic techniques are established methods for peripheral and central venous access as well as for regional anaesthesia. However, transthoracic ultrasonography by non-cardiologists has not yet been routinely established perioperatively, in intensive care medicine or in emergency medicine.

[Monitoring of perioperative fluid management in children].

Invasive monitoring is rarely used in children undergoing routine anaesthesia. Therefore the management of fluid therapy and its maintenance depends often on the experience of the anaesthetist. In situations of high volume uptake and during critical surgical procedures haemodynamic state can easily be underestimated and hypovolaemic episodes remain undetected.
