Introduction Recently, some centers have used extubation during extracorporeal membrane oxygenation (ECMO) to eliminate barotrauma and volutrauma as a lung rest strategy. This study aims to demonstrate the use of extubation during ECMO in children. Methods This retrospective study was conducted from January 1, 2015, to April 1, 2023, in our pediatric intensive care unit. Results In this study, we presented six cases that were extubated during ECMO support. In addition, we followed 130 pediatric patients on ECMO in the same period. Two patients were primarily diagnosed with cardiomyopathy, one with myocarditis, two with congenital heart defect, and one with necrotizing pneumonia. The median age of patients was 99 (interquartile range 25-75) (16.5-192) months, and all were male. Venoarterial ECMO was connected to 4 patients, and venovenous ECMO was connected to 2 patients. Six patients were extubated during ECMO on the 5th, 12th, 3rd, 4th, 3rd and 14th days of their treatment, respectively. While the patients were extubated, three of them were supported by biphasic positive airway pressure, one was supported by nasal continuous positive airway pressure, and two were provided with supplementary oxygen. Three patients were extubated under ECMO and discharged. Conclusion The risk of mechanical ventilation related complications such as volutrauma and barotrauma could minimized in patients extubated under ECMO. In addition, sedatives, analgesics, and muscle relaxant related complications such as delirium, muscle weakness, or prolonged ventilation could reduced via awake ECMO.

Background: The initial extracorporeal membrane oxygenation (ECMO) configuration is inefficient for patient oxygenation and flow, but by adding a Y-connector, a third or fourth cannula can be used to support the system, which is called hybrid ECMO. Methods: This was a single-center retrospective study consisting of patients receiving hybrid and standard ECMO in our PICU between January 2014 and January 2022. Results: The median age of the 12 patients who received hybrid ECMO and were followed up with hybrid ECMO was 140 (range, 82-213) months. The total median ECMO duration of the patients who received hybrid ECMO was 23 (8-72) days, and the median follow-up time on hybrid ECMO was 18 (range, 3-46) days. The mean duration of follow-up in the PICU was 34 (range, 14-184) days. PICU length of stay was found to be statistically significant and was found to be longer in the hybrid ECMO group (p = 0.01). Eight (67%) patients died during follow-up with ECMO. Twenty-eight-day mortality was found to be statistically significant and was found to be higher in the standard ECMO group (p = 0.03). The hybrid ECMO mortality rate was 66% (decannulation from ECMO). The hybrid ECMO hospital mortality rate was 75%. The standard ECMO mortality rate was 52% (decannulation from ECMO). The standard ECMO hospital mortality rate was 65%. Conclusions: Even though hybrid ECMO use is rare, with increasing experience and new methods, more successful experience will be gained. Switching to hybrid ECMO from standard ECMO at the right time with the right technique can increase treatment success and survival. [ABSTRACT FROM AUTHOR]

Background: In this study, we aimed to evaluate the duration of extracorporeal membrane oxygenation (ECMO) and its effect on outcomes. Also, we sought to identify hospital mortality predictors and determine when ECMO support began to be ineffective. Methods: This was a single-center, retrospective cohort study conducted between January 2014 and January 2022. The prolonged ECMO (pECMO) cut-off point was accepted as 14 days. Results: Thirty-one (29.2%) of 106 patients followed up with ECMO had pECMO. The mean follow-up period of the patients who underwent pECMO was 22 (range, 15–72) days, and the mean age was 75 ± 72 months. According to the results of our heterogeneous study population, life expectancy decreased dramatically towards the 21st day. Hospital mortality predictors were determined in the logistic regression analysis in all ECMO groups in our study as high Pediatric Logistic Organ Dysfunction (PELOD) two score, continuous renal replacement therapy (CRRT) use, and sepsis. The pECMO mortality was 61.2% and the overall mortality was 53.0%, with the highest mortality rate in the bridge-to-transplant group (90.9%) because of lack of organ donation in our country. Conclusions: In our study, the PELOD two score, presence of sepsis, and use of CRRT were found to be in the predictors of in-hospital ECMO mortality model. Considering the complications, in the COX regression model analysis, the factors affecting the probability of dying in patients followed under ECMO were found to be bleeding, thrombosis, and thrombocytopenia.

Objective: Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment option providing cardiopulmonary support when standard therapies prove insufficient for reversible diseases. The mean objective of this study was to evaluate our center’s experience with ECMO following pediatric cardiac surgery. Materials and Methods: This retrospective study was conducted in our pediatric intensive care unit (PICU) between November 2014 and March 2021 and included patients who received ECMO following cardiac surgery. Results: Over the 7-year period, 324 patients underwent cardiac surgery, of which 24 (7.4%) required ECMO support. Among them, 13 (54.2%) were female, with a median age of 16.0 (2.0-208) months and a median weight of 7.0 (3.5-70) kg. The mean vasoactive inotrope score (VIS) was 53.9 ± 44.5. Atrioventricular septal defect repair was the most common surgical procedure (n = 8/24, 41.6%). The primary indication for ECMO was low cardiac output syndrome (LCOS) in 14 (58.3%) patients. The median duration of ECMO support was 6.0 (1.0-46.0) days. Nonsurvivors had significantly higher Pediatric Risk Score of Mortality (PRISM) III scores (P = .014) and VIS scores during the pre-ECMO period (P = .004). Early or late neurological complications developed in 12 (50%) patients, with significant differences in lactate levels and pH levels pre-ECMO between those with and without neurological complications (P = .01, P = .02, respectively). We successfully decannulated 16 (66.6%) patients, with a final survival rate of 12 (50%). Conclusion: ECMO plays a crucial role in providing pre- and post-cardiac surgery support for children. LCOS remains the main indication, and high PRISM III and VIS scores are valuable predictors of outcomes. [ABSTRACT FROM AUTHOR]

This scientific letter discusses the use of intravesical tranexamic acid (TXA) for severe macroscopic hematuria in a child with a biventricular assist device (BiVAD). Mechanical circulatory support (MCS) is commonly used in children with end-stage heart failure, and bleeding is a common complication in these patients. Anticoagulant treatment can be interrupted and cystoscopic interventions performed for bleeding control, but the use of intravesical TXA in this patient group is not well-documented. The authors share their experience with intravesical TXA application in a 10-year-old girl with a BiVAD and receiving anticoagulant treatment, which successfully controlled her macroscopic hematuria. They suggest that intravesical TXA may be a useful option for managing severe macroscopic hematuria in patients who require anticoagulants. [Extracted from the article]

Objective: Extracorporeal membrane oxygenation is a life-saving treatment for patients with circulatory and respiratory failure refractory to standard therapy. However, safe and timely patient transport to the referral extracorporeal membrane oxygenation center is critical for better patient outcomes in patients with acute cardiogenic shock. This study aimed to describe children’s features who were transferred to our center under extracorporeal membrane oxygenation by aircraft/ground vehicle and demonstrated the importance of extracorporeal cardiopulmonary resuscitation for transported children. Materials and Methods: We report the first Turkish pediatric case series of patients with acute cardiogenic shock transported by aircraft and ground ambulances on extracorporeal membrane oxygenation support to a referral extracorporeal membrane oxygenation center between January 2016 and January 2021. Results: Overall, 6 patients on venoarterial extracorporeal membrane oxygenation support were transported by aircraft and ground vehicles to our pediatric intensive care unit. Transport was achieved by fixed-wing aircraft in 5 patients and commercial aircraft in 1. Our mobile extracorporeal membrane oxygenation team cannulated 3 patients, and 3 patients were cannulated by the team at the hospital they applied to. The median age was 112 (range: 14-204) months and the median weight was 28.6 kg (range: 8.6-57.2 kg). The etiology of acute cardiogenic shock was fulminant myocarditis in 4 patients, dilated cardiomyopathy in 1, and transposition of great arteries and atrial flutter in 1. The median distance of travel for the patients to our hospital was 618 (407-955) km. No adverse events were detected during aircraft or ground vehicle transport. Conclusion: Mobile pediatric extracorporeal membrane oxygenation transport teams may provide safe aircraft and ground vehicle transportation in high-risk patients with acute cardiogenic shock bridging to survival or long-term circulatory support.

Although infective endocarditis (IE) is rare, it is still important as an infectious disease because of the resulting morbidity and substantial mortality rates. Epidemiological studies in developed countries have shown that the incidence of IE has been approximately 6/100 000 in recent years and it is on the fourth rank among the most life-threatening infectious diseases after sepsis, pneumonia and intraabdominal infections. Although IE is not a reportable disease in Turkey, and an incidence study was not performed, its incidence may be expected to be higher due to both more frequent presence of predisposing cardiac conditions and higher rates of nosocomial bacteremia which may lead to IE in risk groups. Additionally, while IE generally affects elderly people in developed countries it still affects young people in Turkey. In order to reduce the mortality and morbidity, it is critical to diagnose the IE, to determine the causative agent and to start treatment rapidly. However, most of the patients cannot be diagnosed in their first visits, about half of them can be diagnosed after 3 months, and the disease often goes unnoticed. In patients diagnosed as IE, the rate of identification of causative organisms is more than 90% in developed countries, while it is around 60% in Turkey. Furthermore, some important microbiological diagnostic tests are not performed in most of the centers. Some antimicrobials that are recommended as the first option for treatment of IE, particularly antistaphylococcal penicillins, are unavailable in Turkey. These problems necessitate to review the epidemiological, laboratory and clinical characteristics of IE in the country, as well as the current information about its diagnosis, treatment and prevention together with local data. Patients with IE can be followed by physicians in many specialties. Diagnosis and treatment processes of IE should be standardized at every stage so that management of IE, a setting in which many physicians are involved, can always be in line with current recommendations. From this point of view, Study Group for Infective Endocarditis and Other Cardiovascular Infections of the Turkish Society of Clinical Microbiology and Infectious Diseases has called for collaboration of the relevant specialist organizations to establish a consensus report on the diagnosis, treatment and prevention of IE in the light of current information and local data in Turkey. In the periodical meetings of the assigned representatives from all the parties, various questions were identified. Upon reviewing related literature and international guidelines, these questions were provided with consensus answers. Several of the answers provided in the report are listed below: [1] IE is more frequent in patients with a previous episode of IE, a valvular heart disease, a congenital heart disease, any intracardiac prosthetic material, an intravenous drug addiction, chronic hemodialysis treatment, solid organ and hematopoietic stem cell transplantation as compared with normal population. [2] The most frequent causative organisms are Staphylococcus aureus, streptococci, coagulase-negative staphylococci, and enterococci, respectively, both in Turkey and globally. Brucella spp. is the fifth common causative agent of IE in Turkey. [3] The echocardiograpghy is the imaging modality of choice to define cardiac lesions in patients with suspected IE. Both transthoracic and transesophageal echocardiography are generally necessary in almost all patients. Both are inconclusive approximately in 15% of total IE cases whereas the percentage is up to 30% in patients with intracardiac prosthetic devices. In these instances, multi-slice (MS) computed tomography (CT) should be the imaging modality in patients with native valve IE, whereas MS-CT or radiolabelled leukocyte scintigraphy with single-photon emission tomography/CT should be choosen for patients who have prosthetic valve IE within the first 3 months of surgery, and MS-CT or positron-emission tomography/CT should be chosen for patients with prosthetic valve IE after 3 months of surgery. [4] Blood cultures should be taken without any delay to catch-up the febrile period as 3 sets with 30-minute intervals (3 aerobic and 3 anaerobic bottles, totally 6 bottles) in patients with suspected IE. Each set, comprised of 1 aerobic and 1 anaerobic bottle, should be inoculated with 18-20 ml of blood (9 -10 ml blood per bottle). Totally 60 ml of blood should be taken from one patient with suspected IE. Two sets of control blood cultures should be repeated in every 48 hours after initiation of therapy in order to show blood sterility. If causative organism do not grow in the usual blood culture bottles, additional three mycobacterial blood culture bottles should be inoculated in patients with suspected prosthetic valve IE and who had a cardiac surgery in the last decade. [5] The excised valvular tissue from patients with suspected IE should be evaluated both microbiologically and histopathologically. [6] First of all, Wright agglutination test (if negative, by adding Coombs' serum) and indirect fluorescent yaşantibody (IFA) test to investigate Coxiella burnetii phase I IgG antibodies should be done in culture-negative patients. If these two tests are negative, IgG antibodies for Bartonella spp., Legionella spp., Chlamydia spp., and Mycoplasma spp. should be tested respectively and preferably by IFA test. [7] Multiplex polymerase chain reaction (PCR) tests should be used to identify the pathogen in whole blood in a culturenegative patient who has received previous antibiotic therapy. If the blood cultures are negative in a patient who has not received previous antibiotic therapy, PCR tests for 16S rRNA gene analysis and Tropheryma whipplei should be performed on the resected valve obtained during surgery. [8] Histopathological examination of resected valvular tissue in patients with suspected IE give valuable information about the activation and degree of the inflammation. Moreover, histopathological examination with appropriate routine and immunohistochemical staining, aid to identify especially intracellular pathogens like C. burnetii, Bartonella spp. and T. whipplei in blood culture-negative patients. [9] Bactericidal agents given parenterally for long duration is the general principle of antimicrobial treatment of IE. The pathogenic organism, presence of prosthetic material and duration of symptoms specifies the duration of treatment. The therapy duration is generally 4-6 weeks for native valve IE and >6 weeks for prosthetic valve IE. [10] As the efficacy and feasibility of oral antimicrobial choices of left-sided IE are not well defined in Turkey and it is related with substantial mortality, parenteral route should be preferred for the complete duration of antimicrobial treatment of left-sided IE in Turkey. In case of unavailability of intravenous access or outpatient parenteral antibiotic therapy, oral agents may be feasible to complete the therapy duration in stable patients with uncomplicated native valve IE due to drug-susceptible viridans streptococci, provided that initial two weeks should be completed parenterally, and the patient should give an informed consent after notifying all possible risks, and regular post-discharge follow-up should be possible. The decision for oral maintenance therapy has to be given by the IE team. [11] The appropriate antimicrobials should be initiated without any delay as it reduces not only the risk of an embolic event in patients with either acute or subacute IE, but also decreases the mortality associated with sepsis in acute IE. Therefore, the empirical antimicrobials should be promptly initiated after blood cultures are taken. [12] Ampicillin-sulbactam ± gentamicin can be initiated empirically in the treatment of community-acquired, both acute and subacute types of native and late prosthetic valve IE in adults whereas either vancomycin + ampicillin-sulbactam or ceftriaxone ± gentamicin can be the choice for acute types. Vancomycin + cefepime ± gentamicin combination can be initiated empirically in the treatment of nosocomial native, early and late prosthetic valve IE in adults. Gentamicin should be avoided initially in patients with impaired renal function. Rifampin can be added to initial empirical treatment of early prosthetic valve IE. Daptomycin alone is not a drug of choice for initial empirical treatment of IE because of its suboptimal efficacy for streptococci and enterococci in which resistance can easily develop during therapy.

Objective: All innovations in cardiac surgery provide us with new techniques to perform surgery through smaller incisions with less invasive and best cosmetic results. After promising results in minimally invasive cardiac surgery (MICS), pain and cosmetic appearance became important end points, especially for female patients. In the current study, we intended to evaluate the surgical results and cosmetic satisfaction with the periareolar and submammary incision types in cardiac surgery. Methods: Ninety-four female patients underwent MICS between July 2013 and March 2018. MICS was performed in 62 patients via periareolar incision and in 32 patients via submammarian incision. We investigated the incision size, wound infection, pain levels by using a postoperative standard pain-level questionnaire, the postoperative scar size, and patient satisfaction using a postoperative patient questionnaire. Results: Periareolar incision size was smaller than the submammary incision (Group A: 5.6±0.6 vs. Group B: 6.7±0.8, p=0.001). Four patients from Group B had superficial wound infection (p=0.01). Patients who underwent MICS via periareolar incision and submammary incision had similar pain level (p=0.2). The scar tissue was smaller in size and postoperatively healed better in the following days for the patients with periareolar incision due to the elastic structure of breast tissue. (Group A: 4.3±0.4 vs. Group B: 5.3±0.2, p=0.001). Conclusion: Our study suggests that the periareolar approach would be more aesthetic, show better healing, and have a smaller scar size in female patients. [ABSTRACT FROM AUTHOR]

Aims: Statin pretreatment in patients undergoing cardiac surgery is understood to prevent postoperative atrial fibrillation (AF). However, this is based on observational and limited randomized trial evidence, resulting in uncertainty about any genuine anti-arrhythmic benefits of these agents in this setting. We therefore aimed to quantify precisely the association between statin pretreatment and postoperative AF among patients undergoing cardiac surgery. Methods and results: A detailed search of MEDLINE and PubMed databases (1st January 1996 to 31st July 2012) was conducted, followed by a review of the reference lists of published studies and correspondence with trial investigators to obtain individual-participant data for meta-analysis. Evidence was combined across prospective, randomized clinical trials that compared the risk of postoperative AF among individuals randomized to statin pretreatment or placebo/control medication before elective cardiac surgery. Postoperative AF was defined as episodes of AF lasting >=5 min. Overall, 1105 participants from 11 trials were included; of them, 552 received statin therapy preoperatively. Postoperative AF occurred in 19% of these participants when compared with 36% of those not treated with statins (odds ratio 0.41, 95% confidence interval 0.31-0.54, P < 0.00001, using a random-effects model). Atrial fibrillation prevention by statin pretreatment was consistent across different subgroups. Conclusion: Short-term statin pretreatment may reduce the risk of postoperative AF among patients undergoing cardiac surgery. [ABSTRACT FROM AUTHOR]

Background: In this study, we aimed to compare ultrasoundguided versus bronchoscopy-guided percutaneous dilatational tracheostomy outcomes in critically ill adult patients undergoing a median sternotomy., Methods: Between January 2015 and December 2020, a total of 54 patients (17 males, 37 females; mean age: 54.9±13.1 years; range, 39 to 77 years) who underwent elective ultrasound- or bronchoscopy-guided percutaneous dilatational tracheostomy after a median sternotomy were included. We compared the ultrasound-guided group (n=25) with the bronchoscopy-guided group (n=29) regarding all-cause mortality and complications. Safety assessments included major and minor bleeding, procedural hypoxic or hypotensive event, cardiac dysrhythmias, tracheal injury, damage to adjacent structures, and requirement of conversion to open surgical tracheostomy., Results: No tracheostomy procedure-related death was observed in either group. The median time for tracheostomy was 13 (range, 8 to 17) min in the ultrasound-guided group and 10 (range, 7 to 15) min in the bronchoscopy-guided group (p=0.387). There was no need for conversion between the two methods or conversion to surgical tracheostomy for any patient. The overall complication rates did not significantly differ between the groups (p=0.15)., Conclusion: Ultrasound-guided percutaneous dilatational tracheostomy can be safely performed in patients undergoing sternotomy. Complication rates of the procedure are similar to those guided with bronchoscopy., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2021, Turkish Society of Cardiovascular Surgery.)

Any highly infectious and rapidly spreading disease is a primary concern for immunocompromised solid organ transplant recipients. The number of data about the spectrum of clinical illness, the treatment modalities, and the outcomes of COVID-19 in this vulnerable population is scant and still remains empirical. Herein, we report the first COVID-19 case of a heart transplant recipient in Turkey who presented with fever, postnasal discharge, and myalgias for two days. The possibility of lung involvement was ruled out by thoracic computed tomography. Despite stable vital signs, we reduced the intensity of immunosuppressive therapy and maintained home self-isolation promptly. We also commenced a five-day course of hydroxychloroquine 200 mg q12h initially. After confirmation of real-time reverse-transcriptase-polymerasechain- reaction testing of the nasopharyngeal swab positive for COVID-19, the patient was hospitalized. After a loading dose of favipiravir 1,600 mg b.i.d., the patient received a five-day course of favipiravir 600 mg q12h. He was discharged with cure after 23 days of hospital isolation and treatment. In conclusion, treatment process can be affected by the daily electrocardiography, hand-held portable echocardiography, myocardial injury markers, and pulse oximeter for selfmonitoring in the follow-up of previous heart transplant recipients suffering from COVID-19. The lack of treatment protocols in the solid organ transplant recipients with COVID-19 infection and the controversies about the protective effect of immunosuppression invite a global and update discussion., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2020, Turkish Society of Cardiovascular Surgery.)
