RESUMO

ECMO has become a therapeutic modality for in- and out-of-hospital scenarios and is also suitable as a bridging therapy until further decisions and interventions can be made. Case report: A 27-year-old male patient with mechanical aortic valve prothesis had a sudden cardiac arrest (SCA). ROSC had been achieved after more than 60 min of CPR and eight DC shocks due to ventricular fibrillation (VF). The National Ambulance Service unit transported the patient to our clinic for further treatment. Due to the trauma and therapeutic INR, a CT scan was performed and ruled out bleeding. Echocardiography described severely decreased left ventricular function. Coronary angiography was negative. Due to the therapeutic refractory circulatory and respiratory failure against intensive care, VA-ECMO implantation was indicated. After four days of ECMO treatment, the patient's circulation was stabilized without neurological deficit, and the functions of the end organs were normalized. Cardiac MRI showed no exact etiology behind SCA. ICD was implanted due to VF and SCA. The patient was discharged after 19 days of hospitalization. Conclusion: This case report points out that the early application of mechanical circulatory support could be an outcome-determinant therapeutic modality. Post-resuscitation care includes cardiorespiratory stabilization, treatment of reversible causes of malignant arrhythmia, and secondary prevention.

RESUMO

OBJECTIVES: The benefit of using gelatin solution in cardiac surgery is still controversial. Previous data suggested adverse interactions of gelatin infusion with acute kidney injury (AKI) or coagulopathy. The purpose of this study was to evaluate the association between perioperative gelatin use and fluid overload (FO), hemodynamic stability, and outcomes compared to crystalloid-based fluid management. DESIGN: A retrospective study design. SETTING: At a single-center tertiary university setting. PARTICIPANTS: Propensity score-matched cohort study of 191 pairs of patients scheduled for cardiac surgery. INTERVENTIONS: Patients received either gelatin + crystalloid or pure crystalloid-based perioperative fluid management. The primary outcomes were the frequency of FO and hemodynamic stability defined by the vasoactive-inotropic score. Postoperative complications and 3-year survival were analyzed also. MEASUREMENTS AND MAIN RESULTS: Patients who received gelatin experienced more frequent postoperative FO than controls (11.0% v 3.1%, p = 0.006) despite comparable hemodynamic stability in both groups. Gelatin administration was linked with a higher rate of postoperative complications, including blood loss, AKI, and new-onset postoperative atrial fibrillation. Use of gelatin infusion resulted in an adjusted odds ratio of 1.982 (95% CI 1.051-3.736, p = 0.035) for developing early postoperative AKI. This study confirmed a dose-dependent relationship between gelatin infusion and AKI. Thirty-day mortality and 3-year survival were similar in the groups. CONCLUSIONS: Gelatin administration versus crystalloid fluid management showed a significant association with a higher rate of FO and an increased risk for early postoperative AKI in a dose-dependent manner.

RESUMO

OBJECTIVE: The goal of this study was to compare factor concentrate (FC)-based and blood product-based hemostasis management of coagulopathy in cardiac surgical patients in terms of postoperative bleeding, required blood products, and outcome. DESIGN: Retrospective, propensity score-matched analysis. SETTING: Single, tertiary, academic medical center. PARTICIPANTS: One hundred eighteen matched pairs of 433 consecutive patients scheduled for cardiac surgery in two isolated periods with distinct strategies of hemostasis management. INTERVENTIONS: Patients received either blood product-based (period I) or FC-based (period II) hemostasis management to treat perioperative coagulopathy. MEASUREMENTS AND MAIN RESULTS: Patients treated with FC management experienced less postoperative blood loss (907 v 1,153 mL, p = 0.014) and required less red blood cell and fresh frozen plasma transfusion (2.3 v 3.7 units p < 0.0001, and 2.0 v 3.4 units p < 0.0001, respectively) compared with subjects in the blood product-based management group. The frequency of Stage 3 acute kidney injury and 30-day mortality rate were significantly higher in the blood product-based group than in the FC management group (6.8% v 0.8%, p = 0.016, and 7.2% v 0.8%, p = 0.022, respectively). FC management-related thromboembolic events were not registered. The FC strategy was associated with a 2.19-fold decrease in the odds of massive postoperative bleeding (p < 0.0001), a 2.56-fold decrease in the odds of polytransfusion (p < 0.0001), and a 13.16-fold decrease in the odds of early postoperative death (p = 0.003). CONCLUSIONS: FC-based versus blood product-based management is associated with reduced blood product needs and fewer complications, and was not linked to a higher frequency of thromboembolic events or a decrease in long-term survival in cardiac surgical patients developing perioperative coagulopathy and bleeding.

RESUMO

Összefoglaló. Bevezetés: A Marfan-szindróma autoszomális domináns módon öröklodo, szisztémás kötoszöveti betegség. A hosszú távú túlélés szempontjából fontos a nagyérkatasztrófák megelozése. Szívsebészeti szempontból a legfontosabb elváltozás az aortagyök tágulata. Aortagyök-rekonstrukciós beavatkozásaink Bentall-DeBono-, David I. és módosított Yacoub-mutétek, melyek mind preventív jelleggel, mind dissectio esetén jó eredménnyel végezhetok. Célkituzés: A marfanos betegeknél eltéro technikával végzett aortagyök-rekonstrukciós mutéteink összehasonlítása. Módszer: A Semmelweis Egyetem Városmajori Szív- és Érgyógyászati Klinikáján 1993 és 2020 között Marfan-szindrómásoknál elvégzett Bentall-DeBono-, David I. és módosított Yacoub-féle aortagyök-rekonstrukciókat elemeztük. A mutét szerinti csoportok életkora a beavatkozás idején 29,69 (21,98-41,25) év, 29,15 ± 11,99 év és 35,29 ± 14,14 év volt, a fenti sorrendben. Az adatok forrásául a Magyar Marfan Regiszter és az Aortagyök-rekonstrukciós Regiszter szolgált. Eredmények: Az utánkövetési ido 132 ± 81,04 hónap volt a Bentall-, 76 ± 27,77 hónap a David-, valamint 4,5 (0,75-11,75) hónap a Yacoub-mutét esetén. A David- és a Yacoub-beavatkozások gyakrabban voltak profilaktikusak, mint a Bentall-operációk (p = 0,0153; p = 0,0085). A Bentall-mutéteknél ritkább volt a primer mutét esetleges késobbi elégtelenségébol fakadó reoperáció, mint a David-operációknál (p<0,001). David-beavatkozásnál a Bentall-mutéthez képest hosszabb volt a cardiopulmonaris bypass (p = 0,0013) és az aortalefogás ideje (p = 0,0048), valamint David- és Yacoub-mutét esetén gyakrabban lépett fel korai posztoperatív szövodmény, mint Bentall-operációnál (p = 0,0005; p = 0,0037). A késoi szövodmények és a túlélés tekintetében a csoportok nem különböztek. Következtetés: Marfan-szindrómában a leggyakrabban halált okozó szövodmény az akut aortaruptura, illetve akut aortadissectio. Eredményeink alapján mindhárom profilaktikus aortagyök-rekonstrukciós mutéti típus jól reprodukálható és jó eredménnyel végezheto Marfan-szindrómában. Orv Hetil. 2021; 162(18): 696-704. INTRODUCTION: Marfan syndrome is an autosomal dominant, systemic connective tissue disorder. Preventing vascular complications is essential for long-term survival. Aortic dilation is the main cardiac surgical manifestation. Bentall-DeBono, David I and modified Yacoub aortic root reconstructions treat and prevent aortic dissections with great outcomes. OBJECTIVE: Comparing results of aortic root reconstructions in Marfan syndrome. METHOD: We analysed the data of Bentall-DeBono, David I and modified Yacoub operations performed in Marfan syndrome at the Heart and Vascular Center, Semmelweis University between 1993 and 2020. Ages of surgical groups at the time of operation were 29.69 (21.98-41.25) years, 29.15 ± 11.99 years and 35.29 ± 14.14 years, respectively. Data were obtained from the Hungarian Marfan Register and the Aortic Root Reconstruction Register. RESULTS: Follow-up time was 132 ± 81.04 months for Bentall, 76 ± 27.77 months for David and 4.5 (0.75-11.75) months for Yacoub groups. David and Yacoub operations were prophylactic more frequently than Bentall ones (p = 0.0153; p = 0.0085). Freedom from reoperation after primary surgery insufficiency was more common for Bentall than for David procedure (p<0.001). Compared to Bentall, David surgeries required longer cardiopulmonary bypass (p = 0.0013) and aortic cross clamp time (p = 0.0048), more early postoperative complications occurred after David and Yacoub, than after Bentall operations (p = 0.0005; p = 0.0037). Late complications and survival did not differ among the groups. CONCLUSION: In Marfan syndrome, acute aortic rupture and dissection are the main contributors to mortality. Based on our results, the prophylactic aortic root reconstructions are reproducible and can be performed with great outcomes. Orv Hetil. 2021; 162(18): 696-704.

RESUMO

Since the establishment of highly active antiretroviral therapy, survival rates have improved among patients with human immunodeficiency virus infection giving them the possibility to become transplant candidates. Recent publications revealed that human immunodeficiency virus-positive heart transplant recipients' survival is similar to non-infected patients. We present the case of a 40-year-old human immunodeficiency virus infected patient, who was hospitalized due to severely decreased left ventricular function with a possible aetiology of acute myocarditis, that has later been confirmed by histological investigation of myocardial biopsy. Due to rapid progression to refractory cardiogenic shock, extracorporeal membrane oxygenation implantation had been initiated, which was upgraded to biventricular assist device later. On the 35th day of upgraded support, the patient underwent heart transplantation uneventfully. Our clinical experience confirms that implementation of temporary mechanical circulatory support and subsequent cardiac transplantation might be successful in human immunodeficiency virus-positive patients even in case of new onset, irreversible acute heart failure.

RESUMO

AIMS: The PREPARE-MVR study (PRediction of Early PostoperAtive Right vEntricular failure in Mitral Valve Replacement/Repair patients) sought to investigate the alterations of right ventricular (RV) contraction pattern in patients undergoing mitral valve replacement/repair (MVR) and to explore the associations between pre-operative RV mechanics and early post-operative RV dysfunction (RVD). METHODS AND RESULTS: We prospectively enrolled 42 patients (63 ± 11 years, 69% men) undergoing open-heart MVR. Transthoracic three-dimensional (3D) echocardiography was performed pre-operatively, at intensive care unit discharge, and 6 months after surgery. The 3D model of the RV was reconstructed, and RV ejection fraction (RVEF) was calculated. We decomposed the motion of the ventricle to compute longitudinal ejection fraction (LEF) and radial ejection fraction (REF). Pulmonary artery catheterization was performed to monitor RV stroke work index (RVSWi). RVEF was slightly decreased after MVR [52 (50-55) vs. 51 (46-54)%; P = 0.001], whereas RV contraction pattern changed notably. Before MVR, the longitudinal shortening was the main contributor to global systolic RV function [LEF/RVEF vs. REF/RVEF; 0.53 (0.47-0.58) vs. 0.33 (0.22-0.42); P < 0.001]. Post-operatively, the radial motion became dominant [0.33 (0.28-0.43) vs. 0.46 (0.37-0.51); P = 0.004]. However, this shift was temporary as 6 months later the two components contributed equally to global RV function [0.44 (0.38-0.50) vs. 0.41 (0.36-0.49); P = 0.775]. Pre-operative LEF was an independent predictor of post-operative RVD defined as RVSWi < 300 mmHg⋅mL/m2 [OR = 1.33 (95% CI: 1.08-1.77), P < 0.05]. CONCLUSIONS: MVR induces a significant shift in the RV mechanical pattern. Advanced indices of RV mechanics are associated with invasively measured parameters of RV contractility and may predict post-operative RVD.

RESUMO

Antiphospholipid syndrome is an autoimmune disorder with frequent clinical manifestation of arterial, venous or small vessel thromboembolic events and/or foetal morbidity. Hereby, we present a case report of a patient with a large arterial thrombus originating from the ostium of the right coronary artery accompanied by multiple systemic embolization and right ventricular failure. As a bridge-to-recovery strategy, an extracorporeal right ventricular assist device was successfully applied, representing an effective first choice option in selected patients with isolated acute right heart failure.

RESUMO

The mechanical circulatory support (MCS) program of the Semmelweis University Heart and Vascular Centre has become established over the last five years. The main requirements of our MCS program to be developed first were the Heart Transplantation and Heart Failure Intensive Care Unit and a well trained medical team. The wide range of mechanical circulatory support devices provides suitable background for the adequate treatment of our patients in all indications. In this review, we present our results related to extracorporeal membrane oxygenation (ECMO) supports performed in the last five years. Between 2012 and 2017, we applied MCS support in 140 cases, among them 111 patients received ECMO support. The leading indications of ECMO support were the following: primary graft failure after heart transplantation (33 cases), postcardiotomy cardiogenic shock (18 patients), acute decompensation of end-stage heart failure (14 patients), acute myocardial infarction complicated with refractory cardiogenic shock (37 patients), cardiogenic shock developed after transcatheter aortic valve implantation (3 patients), malignant arrhythmia due to drug intoxication (1 patient) and acute respiratory distress syndrome (4 cases). The mortality of patients receiving ECMO support was 46%. The analysis of the results of ECMO support needs to change our approach. The mortality results show that we lost the half of our patients. However, the mortality in the conventionally treated patients would have been 100% without ECMO. In fact, we could save the life of half of these patients. Orv Hetil. 2018; 159(46): 1876-1881.

RESUMO

The authors give a short introduction of the Hungarian and the international history of adult heart transplantation, and highlight the similarities in the evolution of the two programs. Their aim was to show how the Hungarian post-transplant survival changed in the last five years. They wanted to investigate how all the changes they had made in the program affected the post-transplant results. They investigated 496 heart transplantation data and compared to international data.

RESUMO

INTRODUCTION: The acute surgical treatment of infective endocarditis (IE) carries a high risk of postoperative mortality. Most complications are linked to uncontrolled sepsis and inflammatory processes. Cytokine haemoadsorption is an extracorporeal technique which has benefits reported in haemodynamic stability and inflammatory response. CASE REPORT: A 46-year-old male patient underwent emergency cardiac surgery due to progressive IE. Postcardiotomy cardiogenic shock associated with cardiac surgery required the implantation of venoarterial (VA)-ECMO. Three days later, the patient developed secondary septic shock. The novel application of continuous CytoSorbTM treatment installed in the VA-ECMO circuit is demonstrated in this case during the management of simultaneous shocks. Advanced intensive care led to an improvement in the patient's condition, which facilitated successful weaning from mechanical ventilation. However, the patient died from a new onset fulminant septic shock two months after his initial cardiac surgery. DISCUSSION: VA-ECMO is suitable for installation of the CytoSorbTM cartridge. This modality could be an option for high-volume, continuous cytokine haemoadsorption when VA-ECMO is employed without renal replacement therapy. CONCLUSION: This specific application of CytoSorbTM was safe, feasible and contributed to the optimal management of simultaneous shocks.

RESUMO

Low output syndrome significantly increases morbidity and mortality of cardiac surgery and lengthens the durations of intensive care unit and hospital stays. Its treatment by catecholamines can lead to undesirable systemic and cardiac complications. Levosimendan is a calcium sensitiser and adenosine triphosphate (ATP)-sensitive potassium channel (IK,ATP) opener agent. Due to these effects, it improves myocardium performance, does not influence adversely the balance between O2 supply and demand, and possesses cardioprotective and organ protective properties as well. Based on the scientific literature and experts' opinions, a European recommendation was published on the perioperative use of levosimendan in cardiac surgery in 2015. Along this line, and also taking into consideration cardiac surgeon, anaesthesiologist and cardiologist representatives of the seven Hungarian heart centres and the children heart centre, the Hungarian recommendation has been formulated that is based on two pillars: literature evidence and Hungarian expert opinions. The reviewed fields are: coronary and valvular surgery, assist device implantation, heart transplantation both in adult and pediatric cardiologic practice. Orv Hetil. 2018; 159(22): 870-877.

RESUMO

AIM: The aim of this study was to assess the influence of intraoperative cytokine adsorption on the perioperative vasoplegia, inflammatory response and outcome during orthotopic heart transplantation (OHT). METHODS: Eighty-four OHT patients were separated into the cytokine adsorption (CA)-treated group or controls. Vasopressor demand, inflammatory response described by procalcitonin and C-reactive protein, and postoperative outcome were assessed performing propensity score matching. RESULTS: In the 16 matched pairs, the median noradrenaline requirement was significantly less in the CA-treated patients than in the controls on the first and second postoperative days (0.14 vs 0.3 µg*kg-1 *min-1 , P = .039 and 0.06 vs 0.32 µg*kg-1 *min-1 , P = .047). The inflammatory responses were similar in the two groups. There was a trend toward shorter length of mechanical ventilation and intensive care unit (ICU) stay in the CA-treated group compared to the controls. No difference in adverse events was observed between the two groups. The frequency of renal replacement therapy was less in the CA­treated patients than in the controls. CONCLUSIONS: Intraoperative CA treatment was associated with reduced vasopressor demand with a favorable tendency in length of mechanical ventilation, ICU stay and renal replacement therapy. CA treatment was not linked to higher rates of adverse events.

RESUMO

Assessment of right ventricular (RV) function using conventional echocardiography might be inadequate as the radial motion of the RV free wall is often neglected. Our aim was to quantify the longitudinal and the radial components of RV function using three-dimensional (3D) echocardiography in heart transplant (HTX) recipients. Fifty-one HTX patients in stable cardiovascular condition without history of relevant rejection episode or chronic allograft vasculopathy and 30 healthy volunteers were enrolled. RV end-diastolic (EDV) volume and total ejection fraction (TEF) were measured by 3D echocardiography. Furthermore, we quantified longitudinal (LEF) and radial ejection fraction (REF) by decomposing the motion of the RV using the ReVISION method. RV EDV did not differ between groups (HTX vs control; 96 ± 27 vs 97 ± 2 mL). In HTX patients, TEF was lower, however, tricuspid annular plane systolic excursion (TAPSE) decreased to a greater extent (TEF: 47 ± 7 vs 54 ± 4% [-13%], TAPSE: 11 ± 5 vs 21 ± 4 mm [-48%], P < .0001). In HTX patients, REF/TEF ratio was significantly higher compared to LEF/TEF (REF/TEF vs LEF/TEF: 0.58 ± 0.10 vs 0.27 ± 0.08, P < .0001), while in controls the REF/TEF and LEF/TEF ratio was similar (0.45 ± 0.07 vs 0.47 ± 0.07). Current results confirm the superiority of radial motion in determining RV function in HTX patients. Parameters incorporating the radial motion are recommended to assess RV function in HTX recipients.

RESUMO

BACKGROUND: The role of non-infective inflammatory response (IR) in the aetiology of postoperative cognitive dysfunction (POCD) is still controversial. The aim of this controlled, prospective observational study was to assess the possible relationship between the grade of IR, defined by procalcitonin (PCT) changes, and development of POCD related to cardiac surgery. METHODS: Forty-two patients, who were ≥ 60 years of age and scheduled for elective cardiac surgery, were separated into the low inflammatory (LIR) and high inflammatory (HIR) response groups based on their PCT levels measured on the first postoperative day. A matched normative control group of 32 subjects was recruited from primary care practice. The PCT and C-reactive protein (CRP) levels were monitored daily during the first five postoperative days. The cognitive function and mood state were preoperatively tested with a set of five neurocognitive tests and two mood inventories and at the seventh postoperative day. The Reliable Change Index modified for practice (RCIp) using data from normative controls was applied to determine the significant decline in test performance. RESULTS: The LIR (n = 20) and HIR (n = 22) groups differed significantly in the PCT (p < 0.001) but not in the CRP time courses. The incidence of POCD at the first postoperative week was 35.7% in the cohort. The LIR and HIR groups did not vary in the RCIp Z scores of neurocognitive tests and frequencies of POCD (7 vs 8 cases, respectively, p > 0.05). Additionally, there was no difference in the mood states, anxiety levels and perioperative parameters known to influence the development of POCD. CONCLUSIONS: In this study, the magnitude of the non-infective inflammatory response generated by on-pump cardiac surgery did not influence the development of POCD in the early postoperative period in elderly patients.

RESUMO

BACKGROUND: The secondary forms of hemolytic uremic syndrome/thrombotic thrombocytopenic purpura (secondary TMA) emerge as complications of coexisting diseases. OBJECTIVES: We hypothesized that secondary TMA could be characterized by the presence of relative ADAMTS13 deficiency and complement activation, and this relationship may have a prognostic value for outcome. PATIENTS AND METHODS: Fifty-three patients with thrombotic microangiopathy (TMA) and coexisting disease (such as malignancies, sepsis, heart surgery with extracorporeal circulation, solid organ transplantation, systemic autoimmune disorders), 41 patient controls, and 34 healthy controls were enrolled in our case-control study with 30days follow-up. Complement profile (from serum) and activation products, von Willebrand factor (VWF, from EDTA plasma), and ADAMTS13 activity were determined. RESULTS: ADAMTS13 activity was reduced, while VWF level was elevated in secondary TMA patients. The activity of the classical, lectin and alternative pathways, as well as the levels of C3, C4, and Factor H were significantly lower in secondary TMA patients, and were accompanied by high activation product levels (C3a and sC5b-9). Factor H concentration correlated to relative ADAMTS13 deficiency (i.e. VWF/ADAMTS13 ratio (r=-0.368, p=0.019)). 28/53 patients (53%) died during the follow-up period. Increased sC5b-9, C3a, and C reactive protein levels were all associated with a poor patient outcome. CONCLUSIONS: Our results indicate that the secondary TMA syndrome and its poor outcome is characterized by relative ADAMTS13 deficiency, inflammation, and complement activation with consumption via the classical and alternative pathways. It is yet to be determined whether complement inhibition could be a possible therapeutic option for patients with secondary TMA.

RESUMO

UNLABELLED: Liver resection is the curative therapeutic option for hepatocellular carcinoma, biliary tumors, metastases of colorectal and other extrahepatic tumors, living donor liver transplantation and other benign liver diseases. AIM OF STUDY: To summarize the evaluation methods of liver function before living donor liver transplantation and liver resection. METHOD: We summarize the literature about the evaluation of liver function. RESULTS: Perioperative mortality is determined mostly by the extent of preoperative evaluation focused on the liver. After resection the remnant liver parenchyma must cope with the challenge caused by increased metabolism, portal overflow, decreased vascular bed and biliary tract and oxidative stress following the operation. If the remnant liver is unable to grow up to this challenge, acute liver failure occurs. This maintains the necessity of determining the hepatic functional reserve and the hepatic remnant volume. Child-Pugh classification is widely spread to predict outcome. Dynamic functional tests such as indocyanine green retention test, galactosyl human serum albumin scintigraphy and aminopyrine breath tests can be used to evaluate hepatic reserve. To determine remnant liver volume modern imaging processes such as CT volumetry and hepatobiliary scintigraphy are available. CONCLUSION: After the detailed evaluation resection can be limited to an extent which is oncologically radical enough (1% remnant liver tissue/kg) and spares parenchyma which can ensure survival yet. With careful preoperative examination mortality can be reduced even to reach zero.
