41st Annual Cardiothoracic Surgery Symposium (CREF 2022)
The 41st Annual Cardiothoracic Surgery Symposium (CREF 2022) offers cutting-edge presentations, interactive discussions and debates, hands-on workshops, and extracurricular education on topics related to cardiac surgery, cardiopulmonary bypass, extracorporeal perfusion, and extracorporeal life support. It offers Category 1 CME and CEU credits, meeting the specific educational needs of CVOR and CVICU teams: cardiac anesthesiologists, cardiac…
Read MoreElevated Procalcitonin as a Risk Factor for Postoperative Delirium in the Elderly after Cardiac Surgery—A Prospective Observational Study
In a multivariable logistic regression model, preoperative procalcitonin (odds ratio (OR) = 3.05), depressive symptoms (OR = 5.02), age (OR = 1.14), impaired daily functioning (OR = 0.76) along with CPB time (OR = 1.04) were significant predictors of postoperative delirium.

Preoperative impaired response to low-dose ACTH stimulation test is not a risk factor for post-cardiotomic vasoplegia; conversely, higher preoperative copeptin predicts the complication.
Read MoreBlockage of Extracorporeal Circulation During Emergency Surgery for Fulminant Infective Endocarditis.
Extracorporeal circulation was turned on during direct heart massage. After opening of the aorta, the circulation was blocked by total clogging of the arterial line filter by fibrine deposits.
Read MoreCardiac Surgery: Beyond Conventional Sternotomy With Cardiopulmonary Bypass
This article increases nursing-related knowledge of minimally invasive cardiac procedures, providing an overview of current minimally invasive cardiac surgeries and their associated risks and benefits.
Read MoreHaematic Antegrade Repriming Procedure to Initiate A Safer Cardiopulmonary Bypass
HAR is proposed as a new approach to increase the safety of the CPB. Its overall benefits should be properly assessed and validated by current and further studies.

The primary novelty and contribution of this work is in demonstrating the feasibility of collecting continuous sensor data from a surgical team member in a real-world setting.
Read MoreDescription of the Minimized Extracorporeal Circuit to Perform Haematic Antegrade Repriming in Cardiopulmonary Bypass
Detailing the MiECC circuit used during HAR is a differencing feature that increases the replicability of the procedure reducing errors and the impact of the cardiopulmonary bypass.
Read MoreDiabetic Control Agents and Their Impact on Cardiac Surgery Patients: A Clinical Overview
A literature review was performed to identify articles discussing the effects of anti-diabetic medications (ADMs) on cardiovascular outcomes and surgical mortality and morbidity rates.
Read MoreInter-hospital COVID ECMO Air Transportation
The detailed protocol is described alongside initial data of its use. To date, 14 patients have been placed on ECMO support at an outside facility and successfully transported via helicopter to our hub hospital using this protocol.
Read MoreSafely Repositioning Dual-Lumen ECMO Cannulas with A Transfemoral Lasso Snare
We describe three patients who successfully had dual-lumen cannulas repositioned without cessation of ECMO using a transfemoral “lasso” technique.
Read MoreComparison of A Perfusion Simulator to A Clinical Operating Room: Evaluation of Eye Tracking Data and Subjective Perception. A Pilot Study
The use of the simulator for (advanced) training is accepted and explicitly requested by perfusionists. Yet further research is needed to identify the decisive factors (like simulation duration or additional tasks) for a valid execution in the simulator. Furthermore, a larger sample size should be regarded to allow statistical analysis.
Read MoreBrain Protection in Aortic Arch Surgery: An Evolving Field
The neurologic outcomes of brain protection in aortic arch surgery largely depend on the following three major components: cerebral temperature, circulatory arrest time, and cerebral perfusion during circulatory arrest.
Read MoreHype or Hope: Vagus Nerve Stimulation Against Acute Myocardial Ischemia-Reperfusion Injury
In this review, we describe the protective role of VNS in myocardial I/R injury and related potential mechanisms. Then, we discuss the challenge and the opportunity of VNS in the treatment of acute myocardial I/R injury.
Read MoreValidation of a Novel NeurOs Cerebral Oximetry Monitor Against the INVOS Monitor During Cardiac Surgery
In conclusion, the novel NeurOs system was found to correlate with INVOS cerebral oximetry measurements during cardiac surgery.
Read MoreAssociations Between Mean Arterial Pressure During Cardiopulmonary Bypass and Biomarkers of Cerebral Injury in Patients Undergoing Cardiac Surgery: Secondary Results from A Randomized Controlled Trial
We found no significant differences in levels of biomarkers of neurological injury in patients undergoing elective or subacute CABG and/or aortic valve replacement randomized to either a target MAP of 40–50 mmHg or a target MAP of 70–80 mmHg during CBP.
Read MoreRole of Extracorporeal Membrane Oxygenation in Critically Ill COVID-19 Patients and Predictors of Mortality
The present study suggests that ECMO is a potentially lifesaving treatment for selected critically ill COVID‐19 patients. Considering IL‐6 and NT‐per‐BNP, in addition to the RESP score, may enhance outcome predictions.
Read MoreInfluence of Blood Haemoglobin Concentration on Renal Haemodynamics and Oxygenation During Experimental Cardiopulmonary Bypass in Sheep
In experimental CPB blood transfusion to increase Hb concentration from ~7 g dL−1 to ~9 g dL−1 did not improve renal cortical or medullary tissue PO2 even though it decreased whole kidney oxygen extraction.
Read MoreThe Effect of Vacuum-Assisted Venous Drainage on Hemolysis During Cardiopulmonary Bypass
There was no significant increase in hemolysis among the groups, which demonstrates that the VAVD technique, even if lower negative pressure is preferred, can be applied safely and effectively to improve venous drainage and consequently, cardiac decompression, even if smaller venous cannulas are used, and also avoid from superfluous fluid addition to sustain adequate extracorporeal perfusion.
Read MoreContinuous Ultrafiltration During Extracorporeal Circulation and Its Effect on Lactatemia: A Randomized Controlled Trial
The use and control of continuous high-volume hemofiltration through a polyethersulfone membrane during heart-lung surgery could potencially prevent postoperative complications. The reduction of lactatemia implied a reduction in intubation time, a decrease in morbidity and mortality in the intensive care unit and a shorter hospital stay.The use and control of continuous high-volume hemofiltration through a polyethersulfone membrane during heart-lung surgery could potencially prevent postoperative complications.
