Fibrin clot permeability (Ks) in patients on left ventricular assist device.

Patients on left ventricular assist devices (LVAD) are prone to excessive hemostasis disturbances due to permanent contact of artificial pump surfaces with blood components. We aimed to investigate if fibrin clot permeability is altered in patients on long-term continuous-flow LVAD therapy and if the clot permeability is associated with clinical characteristics and adverse events. We investigated 85 end-stage heart failure patients (90.6% men, age 48.6-63.8 years) scheduled for continuous flow long-term LVAD support according to current clinical indications. The patients were assessed periodically: prior to LVAD implantation (T1), 3-6 months (T2) after LVAD implantation, 6-12 months after (T3) and then every 6 months. We tested the first three blood samples (T1-T3) and the last available blood sample (T4), but no longer than 5 years after LVAD implantation. We assessed hemostasis parameters (Activated Partial Thromboplastin Time (APTT) Prothrombin Time, Activated Partial Thromboplastin Time, Fibrinogen, D-dimer, Antithrombin, Thrombin Time, Factor VIII, and von Willebrand Factor, aspirin-induced platelet inhibition, adenosine-diphosphate test) changes during the study period. Fibrin Clot Permeability was evaluated using a pressure system and Permeability Coefficient (Ks) was calculated. We observed a decrease in fibrin clot permeability (Ks) between T1, T2, T3 and T4 time periods; P < 0.01 for each comparison. Fibrin clot permeability was negatively correlated with fibrinogen concentration: r = - 0.51, P < 0.001, factor VIII activity r = - 0.42, P < 0.001. There was no association of Ks with age, Left Ventricular Ejection Fraction (LVEF) and medications P > 0.001, however cumulative measurements in patients on aspirin showed shortening of Ks in this group P = 0.0123. Major adverse cardiac and cerebrovascular events (MACCE) occurred in 36.5% patients, bleeding events in 25.9%, Net Adverse Clinical Events (NACE) in 62.4%; 31.7% patients died, and 17.6% underwent transplantation. The transplantation was considered as the endpoint. Discrepancies in Ks were observed between patients with MACCE, bleeding, and NACE, and patients without adverse events. Ks showed a constant trend towards normalization (P < 0.01) only in patients without adverse events. Patients with advanced heart failure have disturbed clot structure. A trend towards normalization of the Ks values is associated with fewer thromboembolic and bleeding complications in this group of patients.

Systemic Sclerosis as a Challenge for Heart Transplantation: A Case Report.

OBJECTIVE: To assess the principles of qualification and the range of organ transplantation in a patient with diagnosis of system sclerosis with pulmonary manifestation and severe myocardial insufficiency. METHODS: We present the case of a 43-year-old patient with confirmed systemic sclerosis with pulmonary manifestations and biventricular heart insufficiency after disease exacerbation and sudden cardiac arrest in the pulseless electrical activity (PEA) mechanism with effective resuscitation, with increasing shortness of breath and the need for inotropes and levosimendan infusion without a significant improvement in his general status. Owing to the diagnosis of a systemic disease with no option for pharmacologic or any other treatment for heart failure, he was reevaluated and put on an urgent waiting list for isolated heart transplantation. After 7 days, heart transplantation was performed. Given the risk of disease progression and the possibility of future lung transplantation, the pleural cavities were untouched. The standard immunosuppression protocol was followed with the use of rabbit antithymocyte globulin. RESULTS: The patient was extubated at 24 hours after heart transplantation. The results of endomyocardial biopsies performed during the hospital stay and at a 6-month follow-up were negative. The patient was discharged to home after 22 days of an uneventful hospital stay. CONCLUSIONS: Scleroderma as an autoimmunologic disease remains a challenge for the transplantation team as a possible progressive multiorgan insufficiency requiring qualification for organ transplantation. The course of the disease varies depending on the form of systemic sclerosis. Careful assessment, qualification, and determination of appropriate preprocedure and postprocedure immunosuppressive treatment are essential to an uncomplicated course of treatment.

Utility of 64-Slice Coronary Computed Tomography Angiography in Heart Transplant Recipients.

BACKGROUND: Graft vasculopathy is a leading cause of death after heart transplantation (HTx). Diagnosing cardiac allograft vasculopathy (CAV) within this patient group poses significant challenges. This study aimed to evaluate the safety and efficacy of coronary computed tomographic angiography (CCTA) in patients after HTx. METHODS: We enrolled 107 consecutive HTx recipients (26 women, mean age 50 ± 17 years); all were ≥3 years post-HTx with minimal or no evidence of CAV in a prior coronary angiography performed a minimum of 2 years before the current examination. The inclusion criteria comprised an estimated glomerular filtration rate (eGFR) of ≥30, absence of new heart failure symptoms, and no contraindications to iodine contrast or CT scans. All patients underwent a 64-slice CCTA. In cases of minimal or no changes, noninvasive follow-up examinations were conducted. Significant changes in CT prompted additional coronary angiography. RESULTS: Of the enrolled participants, 9 exhibited minimal changes; 98 displayed no changes in coronary angiography. The median time since transplant was 7 years, with IQR of 4 to 11.25 years. Significant changes were excluded in 98 patients. Among the 9 patients with suspected significant CAV, significant changes were confirmed in 8 patients, resulting in percutaneous transluminal coronary angioplasty (PTCA) performed in 6. One patient from this group died shortly after PTCA. No cardiovascular incidents were observed within the remaining group. The median follow-up period was 539 (IQR = 289-654 days). The mean left ventricular ejection fraction at follow-up was 58% ± 5% compared with 58% ± 4% at baseline. At follow-up, the mean eGFR was 64 ± 18 mL/kg/1.73 m2 compared with the baseline value of 67.2 mL/kg/1.73 m2. CONCLUSIONS: CCTA appears to offer a secure and efficient means of assessment in HTx recipients.

Assessment of Selected Parameters of Heart Donors and Recipients and Their Impact on the Transplantation Result.

OBJECTIVE: To evaluate the impact of heart donors and recipients parameters on the outcomes after orthotopic heart transplantation (OHT). METHODOLOGY: Two hundred fifteen patients who underwent OHT from 2020 to 2023 were analyzed. RESULTS: Average donors age 36.3 (±13.1) years, 74 women (34.42%), BMI 25.3 (±4.99), Na+ concentration 153.7 (±11.8) mmol/L. Mean intraventricular septum thickness 10.0 (±2.2) mm, left ventricular end-diastolic diameter 44.3 (±6) mm, ejection fraction 60.3 (±7.92) %. Median procalcitonin was 0.6 ng/mL. Levonor was used in 75.8%, Empressin in 4.2%, Dopamine in 5.1%, Dobutamine in 3.7%, and Adrenaline in 3.7% of donors. The most common cause of death: intracranial injury (34.42%). Cardiopulmonary resuscitation occurred in 34%, alcoholism in 20.9%, nicotinism in 16.3%, and drug addiction in 7.4% of donors. Mean aortic cross-clamping time was 200.3 (±48.8) minutes. Intra-aortic balloon pump (IABP) after OHT required 6.1%, extra corporeal membrane oxygenation (ECMO) 6.1%, and renal dialysis 36% of recipients. The 1-year mortality rate was 19.1%. Death after OHT correlated with: longer aortic cross-clamping time (207.6 vs 198.59 minutes, P = .292), longer extracorporeal circulation time (196.3 vs 186.47 minutes, P = .335), lower Empressin dose (median 0.01 vs 0.02 j.m/min, P = .03) in donors, longer postoperative mechanical ventilation (mean 101.46 vs 23.09 hours, P = .001), more frequent dialysis, IABP or ECMO (P = .001) and older age of the recipient (51.2 vs 44.8 years, P = .014). Previous cardiac surgery or any surgical intervention after transplantation significantly influenced mortality. The remaining donor factors had no impact on the OHT result. CONCLUSIONS: Identification of risk factors in the donor and recipient may improve treatment outcomes after OHT.

Pediatric Heart Transplantation in the Context of Severe Pulmonary Hypertension Secondary to Restrictive Cardiomyopathy-Case Report.

The aim of this study is to analyze the feasibility of performing an isolated heart transplant in patients with severe pulmonary hypertension as a result of restrictive cardiomyopathy. The results present the clinical course from the diagnosis of restrictive cardiomyopathy at the age of 2 until the heart transplant at 8 years old. Initially, the patient was considered for multiorgan transplantation, heart and lungs, due to extremely high pulmonary resistance. However, due to the prolonged waiting period for a donor and the worsening condition of the child, a decision was made to perforate the atrial septum with the implantation of an atrial flow regulator system. After conducting control hemodynamic measurements, the qualification was changed to an isolated heart transplant, accepting the high operative risk associated with the still elevated pulmonary resistance index of 4.9 Wood units. This study describes the medical problems that occurred during postoperative treatment. The patient underwent an orthotopic heart transplant in her eighth year of life. Postsurgery, complications were observed, including generalized seizures and heart transplant rejection reaction. Immunosuppressive therapies were applied, and efforts were made to combat anemia and electrolyte disorders. While the cardiovascular system and heart parameters improved, there were some difficulties in controlling heart rhythm and stabilizing electrolyte levels.

Case Report: Heart aneurysm of unknown origin in a two-year-old child diagnosed in the course of Multisystem Inflammatory Syndrome in Children.

We present a case of a 22-month-old boy with a hypokinetic and thin-walled aneurysm of the left ventricle apex. The lesion was diagnosed during routine echocardiography examination in the course of MIS-C, and its occurrence due to MIS-C is plausible. Cardiac magnetic resonance imaging revealed an akinetic aneurysm of the LV apex with a full-wall ischemic scar. Aortography confirmed a normal course of coronary arteries, with adequate perfusion of essential branches and no evidence of stenosis or aneurysms. The boy underwent consultation with the heart team and was deemed eligible for surgery. The aneurysm was excised up to the margin of healthy tissues, and both the surgery and the periprocedural period were uneventful. Determining the origin of the aneurysm is challenging. The most probable etiology appears to be a congenital lesion. Another consideration is an ischemic lesion that may have resulted from impaired coronary circulation during the complicated course of MIS-C. It is possible that this disturbance resolved spontaneously before aortography was performed. Additionally, a complication of pericarditis cannot be entirely ruled out.

Does the induction immunotherapy (basiliximab) influence the early acute cellular rejection index after orthotopic heart transplantation?- Preliminary assessment report.

The study aimed to determine the influence of induction therapy on the acute cellular rejection (ACR) index in adult heart transplant recipients during the one-year observation. The study population consisted of 256 consecutive adult patients (pts), aged 51.5 (±11.9) years, 199 (77%) men treated with orthotopic heart transplantation (OHT) in the period between 2015 and 2020 in a single high-volume heart transplant center. The endomyocardial biopsies (EMBs) were performed according to the protocol consisting of 7 protocolary EMBs for up to 3 months and 10 EMBs for up to one year after OHT. The rejection index (ACRI) was calculated as the number of scheduled EMBs with the ACR ≥ 2 divided by the total number of protocolary EMBs. The study population was divided into two groups according to the application of basiliximab. The total number of pts. who received basiliximab was 10 (3.9%). The main indications for the usage of the induction therapy were heart retransplantation, mechanical circulatory support (MCS), severe renal insufficiency (eGFR <30 mL/min/1.73 m2), and a panel of reactive antibody (PRA) > 10%. In the group with induction, the mean age was 49 (±14) years; 3 (30%) patients had the MCS prior to OHT, and 3 (30%) patients had heart retransplantation. Four (40%) patients had diabetes mellitus, and 4 (40%) patients had severe renal insufficiency. As maintenance therapy during the observation period, tacrolimus was given to 10 (100%) patients, everolimus to 2 (20%) patients, and MPA to 9 (90%) patients. In the group with no induction, the mean age was 51.8 (±12) years, MCS was used in 56 (23%) patients, 2 (0.8%) patients were retransplanted; 10 (4%) patients had eGFR <30 mL/min/1.73 m2 and 58 (24%) patients had diabetes. Tacrolimus was administered to 243 (99%) patients, cyclosporine to 3 (1%), everolimus to 40 (16%), and mycophenolate to 245 (99.6%) heart recipients. The median one-year ACRI was 0.0, IQR:0.0-0.08 in the group with induction vs. 0.077, IQR: 0.0-0.154 with no induction; p = 0.11. ACRI up to three months was significantly higher in the entire cohort in comparison to up to one year (P < 0.01). The multivariate analysis showed that only everolimus implementation and younger age at the time of transplant influenced patients' mortality rate (P < 0.01). Significant graft rejections (≥ 2R ISHLT) are most common in the first three months after OHT. Patients who are initially at high risk of significant cellular rejection may benefit from induction therapy.

Invasive Pulmonary Aspergillosis After Sars-CoV-2 Infection as Limitation of Contemporary Transplantology: A Case Report.

Invasive fungal infections are uncommon in pediatric heart transplant recipients. Risk and mortality are highest in the first 6 months post-transplant, especially in patients with previous surgery and those requiring mechanical support. There is a possibility that prior SARS-CoV-2 infection may cause a more severe course of pulmonary aspergillosis, especially in immunosuppressed individuals. This report describes a female patient, eight years of age, who was admitted to the pediatric cardiac surgery department with symptoms of end-stage heart failure in urgent need of mechanical circulatory support (MCS). A left ventricular assist device (LVAD) was implanted as a bridge to transplantation. During over a year on the waiting list, LVAD was replaced twice due to the presence of fibrin on the inlet valve. While staying in the ward, the patient underwent SARS-CoV-2 infection. An orthotopic heart transplant was successfully performed after 372 days of MCS with LVAD. One month after transplantation, the girl developed severe pulmonary aspergillosis complicated by sudden cardiac arrest and implantation of venovenous extracorporeal membrane oxygenation (VV ECMO) used for 25 days. Unfortunately, a few days after weaning from VV ECMO, the patient died due to intracerebral bleeding.

Economic Considerations on Costs and Pricing of Two Surgical Techniques for Treating Cranial Cruciate Disease in Dogs.

In surgical treatment of cranial cruciate ligament disease in dogs, Tibial Plateau Levelling Osteotomy (TPLO) and Tibial Tuberosity Advancement (TTA) are commonly established procedures and have proven effective in restoring limb function. Unlike clinical outcome, economic aspects have not been studied as extensively. However, the surgical intervention poses an enormous financial burden on patients' owners. In a veterinary practice setting, this study compares prices for TPLO and TTA and examines prices differences as well as potential cost drivers. Charges for veterinary treatments are based on the Gebührenordnung für Tierärztinnen und Tierärzte (GOT), which is mandatory for veterinarians in Germany but allows a certain range in billing. This study found that TPLO is charged at a higher price than TTA; however, this might not cover the additional costs of this procedure. The price is also associated with weight, heavier dogs being more expensive. The underlying strategies for pricing decisions may be based on costs, as efforts for TPLO and heavier dogs are higher in terms of a prolonged surgical time, the number of staff involved and in surgeons' training. Price setting may also be based on a quality promise, suggesting better clinical outcome in a more expensive procedure. Future investigations should involve economic considerations and consider cost-effectiveness analysis when evaluating surgical treatment options.

Long-term results of pediatric heart transplantations: Single-center experiences.

BACKGROUND: Heart failure (HF) is characterized by significant mortality in both adults and children. Characteristics of pediatric HF are feeding problems, poor weight gain, exercise intolerance, or dyspnea. These changes are often accompanied by endocrine disorders. The main causes of HF are congenital heart defects (CHD), cardiomyopathies, arrhythmias, myocarditis, or heart failure secondary to oncological treatment. Heart transplantation (HTx) is the method of choice for treatment of end-stage HF in pediatric patients. AIMS: This article aimed to summarize the single-center experience in heart transplantation in children. METHODS: Between 1988 and 2021 in the Silesian Center for Heart Diseases in Zabrze, 122 pediatric cardiac transplantations were performed. In the group of recipients with failing Fontan circulation, HTx was performed in 5 children. The study group was evaluated for the postoperative course: rejection episodes depending on the medical treatment scheme, coinfections, and mortality. RESULTS: One-, 5-, and 10-year survival rates between 1988 and 2001 were 53%, 53%, and 50%, respectively. One-, 5-, and 10-year survival rates between 2002 and 2011 were 97%, 90%, and 87%, respectively; between 2012 and 2021 (1-year of follow-up), the survival rate was 92%. The main cause of mortality both in early and late periods after transplantation was graft failure. CONCLUSIONS: Cardiac transplantation in children remains the main method of treatment for endstage heart failure. Our results at both early and long-term posttransplant periods are comparable to those obtained in the most experienced foreign centers.

Novel Hybrid Treatment for Pulmonary Arterial Hypertension with or without Eisenmenger Syndrome: Double Lung Transplantation with Simultaneous Endovascular or Classic Surgical Closure of the Patent Ductus Arteriosus (PDA).

Patients with pulmonary arterial hypertension (PAH) become candidates for lung or lung and heart transplantation when the maximum specific therapy is no longer effective. The most difficult challenge is choosing one of the above options in the event of symptoms of right ventricular failure. Here, we present two female patients with PAH: (1) a 21-year-old patient with Eisenmenger syndrome, caused by a congenital defect-patent ductus arteriosus (PDA); and (2) a 39-year-old patient with idiopathic PAH and coexistent PDA. Their common denominator is PDA and the hybrid surgery performed: double lung transplantation with simultaneous PDA closure. The operation was performed after pharmacological bridging (conditioning) to transplantation that lasted for 33 and 70 days, respectively. In both cases, PDA closure effectiveness was 100%. Both patients survived the operation (100%); however, patient no. 1 died on the 2nd postoperative day due to multi-organ failure; while patient no. 2 was discharged home in full health. The authors did not find a similar description of the operation in the available literature and PubMed database. Hence, we propose this new treatment method for its effectiveness and applicability proven in our practice.

Treatment of Pediatric Patients With COVID Infection After Heart Transplantation.

The COVID-19 pandemic that has been ongoing since the beginning of 2020 has forced health care into a difficult struggle for wellness and the lives of patients. International data and our observations show that the course of the disease in these patients is different than in the general population. Symptoms depend on the immunosuppression and severity of viremia. The period of viral replication is much longer. Our observations include 4 pediatric patients post heart transplant who became infected with the coronavirus. One patient was infected in the hospital during perioperative period. Two others required hospitalization because of the severity of symptoms, and 1 was treated on an outpatient basis. The applied treatment included the reduction of immunosuppression, low-molecular-weight heparin, amantadine or remdesivir, steroids, and supplementation with zinc and vitamins C and D. Based on the antigenic tests performed, we determined the period of active replication to be 3 to 8 weeks from the onset of the first symptoms.

Standards of Psychological Care for Pediatric Patients Awaiting Heart Transplantation and Those Requiring Mechanical Circulatory Support.

Children waiting for a heart transplant who require mechanical circulatory support often experience many months of hospitalization. This has a significant impact on their mental health and their development. Additional risk factors for these disorders are neurologic complications associated with the used treatment. To counteract developmental dysfunctions (despite successful heart transplantation) and possible disability in the sphere of mental health as well as to improve executive functions of children after a neurologic incident, there is a need for comprehensive care provided by a clinical psychologist who is a member of a multidisciplinary medical team taking care of the patient. Based on our own experience, standards of psychological care were developed for pediatric patients awaiting heart transplantation and those requiring mechanical circulatory support.

Pregnancies After Orthotopic Heart Transplantation: A Single-Center Experience.

BACKGROUND: Patients who underwent orthotopic heart transplantation have improved survival and quality of live. Some of them are women of childbearing age and have a wish to be pregnant. If the decision to have a child is made, the patient needs a multidisciplinary approach. MATERIAL AND METHODS: We analyzed the whole cohort of patients after orthotopic heart transplantation. From the whole group we extracted women of childbearing age between 16 and 45 years and at least 1 year after transplantation (85 patients). From this group, 8 patients gave birth to children. RESULTS: No cardiocirculatory problems were observed in the mothers during pregnancy and in follow-ups. Strong changes in immunosuppressive drug levels were observed during and directly after the pregnancies. Two children were born prematurely (at 31 and in 34 weeks of gestation). Two children developed cardiomyopathy (the same as in mother). CONCLUSION: The decision of childbearing should be made individually considering each patient's medical history and potential risks connected with the pregnancy. Pregnancy after heart transplantation is relatively safe for the mother. Risk of transmitting cardiomyopathies to the children, especially hypertrophic cardiomyopathy, is high. The patients should be aware of this fact and be carefully counseled preconceptionally.

Patient-Related Preoperative Clinical Factors Influencing 1-Year Survival After Orthotopic Heart Transplantation - A Single Center Polish Experience.

BACKGROUND End-stage heart failure is a growing problem in Poland. Orthotopic heart transplantation remains the best treatment option. Although increasing, the number of heart transplants is disproportionately low compared with patient need. Therefore, it is crucial to identify factors contributing to improvement of heart transplantation outcomes. To find factors providing best survival and optimal recipient selection, we analyzed pretransplant patient-related clinical factors. MATERIAL AND METHODS Between May 2015 and May 2020, we performed 258 cardiac transplants at our institution. We reviewed possible patient-related clinical factors affecting the 1-year survival of our patients and analyzed factors related to survival. Mean age at transplant was 53.5 (±11.8) years; 22.9% of patients were women. Preoperative factors were analyzed using univariable and multivariable analyses. RESULTS In this cohort, 31.8% were diabetic, 43% had ischemic etiology of heart failure, and 15.3% had reversible pulmonary hypertension. Mechanical circulatory support was used in 22%. During 1-year observation, 64 (24.8%) patients died. Univariable analysis showed ischemic etiology (hazard ratio [HR]=2.05, CI=1.227-3.429; P=0.01) and left ventricular assist device were associated with 1-year risk of death (HR=1.953, CI=1.090-3.499; P=0.02). Urgent listing trended toward worsened prognosis (HR=1.509, CI=0.95-2.397; P=0.08). Multivariable analysis showed ischemic etiology (HR=1.81, CI=1.075-3.059; P=0.03), total mechanical circulatory support (HR=1.93, CI=1.080-3.437; P=0.03), decreased eGFR (HR=0.987, CI=0.975-0.998; P=0.03), and protein level (HR=0.97, CI=0.951-0.998; P=0.04) were independently associated with worse 1-year survival after transplantation. CONCLUSIONS Ischemic etiology and mechanical circulatory support were the most important preoperative factors. Malnutrition and renal failure were additional risk factors. Age alone did not influence 1-year survival.

Everolimus-eluting stents versus sirolimus-eluting stents in patients with cardiac allograft vasculopathy.

INTRODUCTION: Cardiac allograft vasculopathy remains one of the most important factors leading to chronic cardiac allograft rejection. When revascularization is needed percutaneous coronary interventions are the method of choice. AIM: To compare the short- and long-term outcomes of cardiac allograft vasculopathy patients treated with everolimus- (EES) or sirolimus-eluting stents (SES). MATERIAL AND METHODS: Between December 2012 and December 2020, 319 patients after heart transplantation undergoing coronary angiography at our institution were analysed. Subsequently 39 patients underwent de novo angioplasty with second-generation EES. The primary study endpoint was angiographic restenosis as evaluated by quantitative coronary angiography. Secondary outcomes included binary restenosis, target lesion revascularization and cardiac death during the follow-up period (6 months). RESULTS: Twenty-four patients were treated with EES and 15 treated with SES. No significant differences were observed regarding the rate of risk factors of cardiovascular diseases and comorbidities. The patients treated with EES were younger (55.8 ±11.8 vs. 60.1 ±12.2) and less frequently male (79% vs. 93%). The majority of patients were diagnosed with single vessel disease with LAD involvement (62% and 86% in the EES group, and 47% and 56% in the SES group). In 6 months follow-up, late lumen loss was comparable in both groups, 0.19 ±0.15 vs. 0.14 ±0.15, and binary restenosis was 4% and 0% for EES and SES groups, respectively. CONCLUSIONS: Second generation drug-eluting stents eluting rapamycin analogues are associated with high direct efficacy of procedures and low incidence of restenosis in a 6-month follow-up.

Off-pump versus on-pump coronary artery surgery in octogenarians (from the KROK Registry).

BACKGROUND: According to the medical literature, both on-pump and off-pump coronary artery surgery is safe and effective in octogenarians. OBJECTIVES: The aim of our study was to examine the epidemiology, in-hospital outcomes and long-term follow-up results in octogenarians undergoing off-pump and on-pump coronary artery surgery utilizing nationwide registry data. METHODS: All octogenarians (≥ 80 years) enrolled in the Polish National Registry of Cardiac Surgical Procedures (KROK Registry), who underwent isolated coronary surgery between January 2006 and September 2017 were identified. Preoperative data, perioperative complications, hospital mortality and long-term mortality were analyzed. Unadjusted and propensity-matched comparisons were performed between octogenarians undergoing off-pump and on-pump coronary artery bypass surgery. RESULTS: Octogenarians accounted for 4.1% of the total population undergoing coronary artery surgery in Poland during the analyzed period (n = 152,631) and this percentage is increasing. Among 6,006 analyzed patients, 2,744 (45.7%) were operated on-pump and 3,262 (54.3%) were operated off-pump. Propensity-matched analysis revealed that patients operated on-pump were more often reoperated due to postoperative bleeding and their in-hospital mortality was higher (6.6% vs 4.5%, p = 0.006 and 8.7% vs 5.8%, p = 0.001, respectively). Long-term all-cause mortality was lower among patients operated off-pump (p = 0.013). CONCLUSION: On the basis of our findings we suggest that off pump technique should be considered as perfectly acceptable in octogenarians.
