2020 World Heart and Cardiothoracic Surgery Conference (2020WHCS) is a premiere educational Heart Congress in the field of Cardiothoracic Surgery and Cardiology that rotate between continents and are organized in collaboration with national and international Cardiac societies and associations.
Read MoreDevelopment of A Valve Type Semi-Closed Extracorporeal Circulation System
In Japan, perfusionists who work on other clinical tasks are involved in cardiopulmonary bypass. Moreover, the number of cases they can perform is limited. In view of this situation, valve type semi-closed extracorporeal circulation (VACC) was developed as a system that enables extracorporeal circulation (ECC) regardless of perfusionists’ experience.
Read MoreComparison of Microcirculatory Perfusion in Obese and Non-Obese Patients Undergoing Cardiac Surgery with Cardiopulmonary Bypass
Microcirculatory perfusion did not differ between obese and lean patients the day before surgery. CPB decreased microcirculatory perfusion with 9% in both groups, but this was only significant in lean patients (p < 0.05). Three days following surgery, microcirculatory perfusion was restored in both groups. In conclusion, microcirculatory perfusion was equally disturbed during cardiac surgery with CPB in metabolically healthy obese patients compared to lean patients.

It is thus demonstrated that the surplus energy provided by pulsatile flow remains moderate (of order 10 mmHg), but that it can be improved by changing the relative shapes of the pressure and flow waves.
Read MoreNadir Oxygen Delivery During Pediatric Bypass as A Predictor of Acute Kidney Injury
The lowest suitable DO 2i during CPB in the present population undergoing pediatric cardiac surgery was 353 mL/min/m 2. And below this threshold, there was a high probability of inducing CS-AKI.
Read MoreBlood Cell Adhesion to Arterial Filters Analysis by Scanning Electron Microscopy and Real-Time PCR Assay: Observational Clinical Study in Cardiac Surgery Patients
There was adhesion of blood elements, especially nucleated platelets, on all arterial filters studied. Although the arterial filter worked as a safety device, that possibly prevented arterial embolisation, it may also have caused greater hyperfibrinolysis during cardiopulmonary bypass.
Read MoreFunctional Brain Isolation Technique for Stroke Prevention in Thoracic Endovascular Aortic Repair
To prevent embolic stroke during thoracic endovascular aortic repair, we have adopted the brain isolation technique since June 2014 in 9 selected high-risk patients (9/134: 6.7%) having ulcerated or protruding atheromas within the proximal aorta.
Read MoreIntraoperative Collection of Autologous Platelet-Rich Plasma from The Cardiopulmonary Bypass Circuit Upon Initiation of Extracorporeal Circulation
Autologous PRP can be safely collected by drawing blood from the CPB circuit, platelet count and aggregation ability significantly decreased after CPB including autologous PRP collection. Some improvement was detected in the number of the platelets count and platelet aggregation ability by administrating an autologous PRP even if autologous PRP is collected from CPB circuit.

Our document should be the basis of future Task Forces to develop a more comprehensive consensus considering new evidence uncovered during the COVID-19 pandemic.

The del Nido cardioplegia was found to be efficacious, safe and more economical alternative to St. Thomas solution.

This narrative review explores those clinical and technical limitations and proposes solutions and alternatives in order to avoid some of those pitfalls.
Read MoreEstimation Model for Hypothermic Circulatory Arrest Time to Predict Risk in Total Arch Replacement
As with the actual hypothermic circulatory arrest time, the predicted hypothermic circulatory arrest time using our model detected significant factors associated with major adverse outcomes. These results indicated that this prediction model for hypothermic circulatory arrest time may be effective.
Read MoreFactors Associated with Acute Kidney Injury and Mortality During Cardiac Surgery
A history of hypertension was predictive of the development of CSA-AKI, and preoperative eGFR was an independent predictor of mortality in this cohort. Both factors are modifiable.
Read MoreLessons Learned on A New Procedure: Nonsternotomy Minimally Invasive Pulmonary Embolectomy
The initial data was positive and suggested that this approach is safe and feasible. We now broaden our experience with another two patients who underwent this approach, and highlight a number of technical and management modifications that have been made to optimize the procedure.
Read MoreCorrelating Oxygen Delivery on Cardiopulmonary Bypass with Society of Thoracic Surgeons Outcomes Following Cardiac Surgery
Low DO2 on bypass may be associated with morbidity/mortality following cardiac surgery, particularly in patients undergoing nonisolated CABG. These results underscore the importance of goal-directed perfusion strategies.
Read MoreHypofibrinogenemia Can Be Estimated by The Predictive Formula in Aortic Surgery
The SFL at the termination of CPB in aortic surgery can be predicted by the preoperative SFL, body weight, CPB time and surgical approach. The predictive formula is useful for developing a hemostasis strategy, including preparing for blood transfusion.
Read MoreSuccessful Antithrombin Administration in Andexanet Alfa-Associated Heparin Resistance
During routine CPB, high-dose unfractionated heparin (UFH) prevents consumptive coagulopathy and the formation of thrombi within the CPB circuit and the patient’s circulation. Prior treatment with andexanet alfa can pose difficulties in achieving adequate anticoagulation during CPB with UFH. The administration of antithrombin, in combination with UFH, may overcome these difficulties.
Read MoreMinimum Alveolar Concentration of Sevoflurane as a Single Hypnotic Agent to Maintain BIS Below 50 in Patients During Normothermic Cardiopulmonary Bypass
MACBIS50 of sevoflurane as a single hypnotic agent was 0.82% in patients undergoing CABG during normothermic CPB.
Read MoreRationale for the Role of Heparin and Related GAG Antithrombotics in COVID-19 Infection
The SARS-CoV-2 pandemic has focused attention on prevention, restriction and treatment methods that are acceptable worldwide. This means that they should be simple and inexpensive. This review examines the possible role of glycosaminoglycan (GAG) antithrombotics in the treatment of COVID-19. The pathophysiology of this disease reveals a complex interplay between the hemostatic and immune systems that can be readily disrupted by SARS-CoV-2.

Results from this exploratory, hypothesis-generating retrospective, observational study shows that fHb ratio at the end of CPB might be used as a novel, widely applicable biomarker for AKI. The use of fHb ratio might help for an early detection of AKI, compared with prediction based only on urinary biomarkers.
Read MoreEffect of Different Types of Cerebral Perfusion for Acute Type A Aortic Dissection Undergoing Aortic Arch Procedure, Unilateral Versus Bilateral
In our study, it was observed that b-ACP procedure exhibited shorter CPB time, milder hypothermia, shorter ventilation time, lower incidence of postoperative hypoxia, and neurological dysfunction compared to u-ACP. Meanwhile, the incidence of ND was independently associated with three factors: preoperative neurological dysfunction, CPB time, and type of cerebral perfusion.
