Introduction; The diagnosis of COVID-19 is quite challenging due to the inconsistent correlation between laboratory findings, radiological imaging, and the clinical picture and contact history of the patient. The patients who underwent cardiac surgery with cardiopulmonary bypass (CPB) face double risk because CBP triggers an intense inflammatory response and the leading cause of mortality in COVID-19 patients is “cytokine storm”. In our institution 15 confirmed cases operated on with open-heart surgery. 9 cases isolated CABG, 4 cases valvular combined with CABG, and 1 valvular disease. Materials and method; All patients undergoing elective or urgent cardiac surgery at “Mother Theresa” ’s Hospital from 11 March to 30 November 2020 were included in this study. Patients diagnosed with COVID-19 infection via positive throat swab taken due to clinical suspicion postoperatively were reviewed. Patients characteristics, type of intervention, date of COVID-19 diagnosis. Results: 9 patients (72%) normal recovery, no respiratory failure, only 3-5 days of fever (max 39,4). 3 of them a moderate respiratory failure. 3 patients with severe respiratory failure. Only 3 deaths (26,6%). Recommendation: It's important to a preoperative screening for COVID-19 patients. The outcome of cardiac surgical patients who contracted COVID-19 infection perioperatively is extremely poor. Aggressive respiratory assistance (early intubation), high doses of corticosteroids, and anticoagulation, better results.

Objective This novel preliminary study sought to capture dynamic changes in heart rate variability (HRV) as a proxy for cognitive workload among perfusionists while operating the cardiopulmonary bypass (CPB) pump during real-life cardiac surgery. Background Estimations of operators’ cognitive workload states in naturalistic settings have been derived using noninvasive psychophysiological measures. Effective CPB pump operation by perfusionists is critical in maintaining the patient’s homeostasis during open-heart surgery. Investigation into dynamic cognitive workload fluctuations, and their relationship with performance, is lacking in the literature. Method HRV and self-reported cognitive workload were collected from three Board-certified cardiac perfusionists ( N = 23 cases). Five HRV components were analyzed in consecutive nonoverlapping 1-min windows from skin incision through sternal closure. Cases were annotated according to predetermined phases: prebypass, three phases during bypass, and postbypass. Values from all 1min time windows within each phase were averaged. Results Cognitive workload was at its highest during the time between initiating bypass and clamping the aorta (preclamp phase during bypass), and decreased over the course of the bypass period. Conclusion We identified dynamic, temporal fluctuations in HRV among perfusionists during cardiac surgery corresponding to subjective reports of cognitive workload. Not only does cognitive workload differ for perfusionists during bypass compared with pre- and postbypass phases, but differences in HRV were also detected within the three bypass phases. Application These preliminary findings suggest the preclamp phase of CPB pump interaction corresponds to higher cognitive workload, which may point to an area warranting further exploration using passive measurement.

Abstract Background Type A aortic dissection is a very dangerous, fatal, and emergency condition for surgery. Acute aortic dissection is a rare condition, such that many patients will not survive without reconstructive surgery. Case presentation We present a case 24-year-old male who came with symptoms of shortness of breath and cough. The patient underwent ECG, chest radiology, and ultrasound, where the patient was found to have right pleural effusion while his ECG was normal. In the history taken from the patient, he had no underlying disease, no history of heart diseases in his family. For a better diagnosis, ETT and aortic CT angiography was performed on the patient which confirmed the evidence of dissection. Immediately after the diagnosis, necessary arrangements were made for open heart surgery and the patient was prepared for surgery. The patient was admitted in the cardiac surgery ICU for 5 days and his medication was carefully administered. After the conditions were stabilized, the patient was transferred to the post-cardiac surgery ICU ward. The patient was discharged from the hospital one week after the surgery and returned to the office as an OPD one week after his discharge. Conclusion Various risk factors can play a role in creating aortic dissection. Therefore, it is necessary to pay attention to patients’ history for achieving a quick and definitive diagnosis. Therefore, to control the complications of placing the cannula as well as the duration of the surgery, it is very important to reduce the duration of pumping on the patient and to be very careful during the cannula placement.

Background: Acute kidney injury (AKI) is one of the most serious complications during the postoperative period of cardiac surgery. Multiple variables predict the ARF after cardiac surgery. Objective of this study was to evaluate the significance of pre and peri-operative variables which may help in predicting the chances of developing ARF after cardiac surgery.Methods: This study was an observational, prospective study conducted among patients who were scheduled to undergo open heart surgery under cardiopulmonary bypass.Results: In total, 50 patients who underwent open-heart surgery, ARF was seen in 5 patients, with the incidence rate of 10%. Acute renal failure was present in one patient with ejection fraction <35, 2 patients had ejection fraction between 35 to 50 and 2 patients with ejection fraction >50. It was seen in 4 patients with 1-2 hrs of cardiopulmonary bypass and in 1 patient with >2 hrs of cardiopulmonary bypass. ARF was also seen in 4 patients with hematocrit between 22-26% and in 1 patient with >26%.Conclusions: The study provided a clinical variable score that can predict ARF after open-heart surgery. The score enhances the accuracy of prediction by accounting for the effect of all major risk factors of ARF.

Organ Dysfunctions

Cardiopulmonary bypass is associated with an injury that may cause pathophysiological changes in the form of systemic inflammatory response syndrome (SIRS) or multiple organ dysfunction syndrome (MODS). In the present study, we investigated the inflammatory response of patients with multiple organ dysfunctions following open-heart surgery. Plasma levels of cytokines (IL-1β, IL-6, IL-8, IL-18) and procalcitonin (PCT) were measured on the first four postoperative days in 12 adult male patients with SIRS and two or more organ dysfunctions after myocar-dial revascularization (MODS group), and 15 patients without organ dysfunctions (SIRS group). All cytokines (except IL-1β) and PCT were significantly elevated in MODS patients, with peak values at the first two postoperative days. The results of our study show a different expression of members of the IL-1 family following extracorporeal circulation. For the first time, we can document that IL-18 is involved in the inflammatory response and the initiation of the MODS following cardiopulmonary bypass. In addition to APACHE-II score, PCT, IL-8, and IL-18 may be used as parameters for the prognosis of patients with organ dysfunctions after cardiac surgery. Furthermore, it must be noted that the duration of the surgical procedure is one of the most important factors for the initiation of the inflammatory response.

Relevanc. Surgical Site Infection (SSI) after open heart surgery is a significant problem in clinical, social, and economic aspect which causes the need to identification of the preferred procedures for successful prevention of the SSI.Objectives. To determine risk of the SSI in cardiac surgery depending on complexity of intervention, using of cardiopulmonary bypass (CBP) and use of both internal mammary arteries (IMA).Methods. Prospective observations study from 2010 to 2019 in cardiac surgery department of the Ural Institute of Cardiology, where in total 4993 open heart surgery procedures were consecutively performed. All SSI cases were recorded up to 90 days after surgery. The analysis was performed to identify risk of cardiopulmonary bypass (CPB), bilateral IMA grafting and combined procedures on the risk of the postoperative wound infection.Results. During the investigation period, total 220 cases of the SSI (4,5%) have been registered of the 4993 patients undergoing open heart surgery. It included 42 cases of deep sternal infection (0,9%) and 178 cases of superficial infection (3,6%). The main pathogen identified was Staphylococcus epidermidis (56,4%). During the hospital period, 151 cases (66,5%) of SSI have been detected, with the median time to detection of the complication 6 days. The relative mortality risk in deep sternal infection group was 4,4 times higher than in the group without SSI (HR 4,6, 95 % CI 1,5-13,9, p=0,003624). CABG increases the relative risk of SSI in compare with non-CABG procedures (OR 3,086169; 95%CI 1,281 – 7,437), while the complexity of the operation (combined versus isolated interventions) does not significantly increase the risk (OR 0.972283; 95% CI: 0.696 - 1.359). The incidence of SSI in the group of in situ BIMA grafting was 8.8%, significantly increasing the likelihood of the SSI in compare to those with SIMA (OR 2.167983, 95% CI 1.463 - 3.212; p =0,000057). CBP significantly increases the risk of postoperative wound infections (OR 1.523890, 95% CI 1.149 - 2.022, p = 0.001742).Conclusions. Refusal of cardiopulmonary bypass, simultaneous procedures and bilateral coronary artery bypass does not allow completely to avoid postoperative wound infections. Nevertheless, the technical features of the preparations and use of grafts, including skeletonization, prevention of coagulation and the preference for sequential composite CABG, can reduce the risk associated with the type of the open heart surgery.

The beginnings of cardiac surgery in Serbia date back to the aftermath of World War II, when the first ?closed heart surgery? was performed in Belgrade. It was done by Professor Vojislav Stojanovic at the Second Surgical Clinic, and shortly afterwards, during the 1950s, by Professor Izidor Papo at the Medical Military Academy, also in Belgrade. ?Open heart surgery,? using heart-lung machine, was introduced in Serbia in 1960, and performed by the same cardiac surgery pioneers. Some of the very first heart operations in the world had been done before cardiac surgery was even officially recognized as a surgical discipline. Therefore, they were performed only as lifesaving procedures in patients with heart wounds. This article describes the first successful surgical treatment of heart wound in Serbia. It was a penetrating revolver wound, and the operation took place on April 7, 1928, at Valjevo City hospital, performed by Dr. Jovan Mijuskovic, who had received his degree from the School of Medicine in Vienna in 1917, and over the years worked as director and chief of surgical departments in various hospitals ? Cuprija, Valjevo, as well as in the City Hospital in Belgrade. He was elected Professor of History of Medicine at Belgrade School of Medicine in 1936. In 1941 he was appointed Minister of Health in the pre-war Serbian Government. Sadly, upon liberation of Belgrade in 1944, this surgical pioneer was arrested and executed.

A Prospective Study

Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD) newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB), has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels.Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN) measurement were drawn at five perioperative time-points.Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak(P<0.01)during CPB and at the end of the surgical procedure. Moreover, ADN showed a flat pattern and no significant differences(P>0.05)have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery.Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

A miniaturized cardiopulmonary bypass circuit enables the safe performance, in selected pediatric patients, of bloodless open heart surgery. As the latest survival rates in neonatal and infant cardiac surgery have become satisfactory, investigators have concentrated upon the improvement of existing procedures. Institutional guidelines and multidisciplinary efforts undertaken in the pre- and postoperative periods are of great importance, concerning bloodless CPB and should be seriously pursued by all involved caregivers. This review reflects upon the selective, most relevant requirements for success of asanguinous neonatal and infant CPB: acceptable level of hemodilution during the CPB, patient preoperative hematocrit value and volume of CPB circuit. We present an assessment of practical measures that were also adapted in our institution to achieve an asanguinous CPB for neonatal and infant patients.
