Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Phytophthora infestans (Mont.) de Bary is a destructive potato pathogen. Changing weather conditions are among the factors that influence the pathogen population structure. In this study, 237 P. infestans isolates were collected from a single unprotected experimental field in an area with high late-blight pressure located in Boguchwała in the southeastern part of Poland during 15 growing seasons (2000-2014). The isolates were assessed for mating type, mitochondrial haplotype, resistance to metalaxyl, virulence, and polymorphism of 14 single-sequence repeat markers (SSRs). The results revealed 89 unique genotypes among the 237 P. infestans isolates. Eighty-seven isolates belonged to genotype 34_A1, which was detected in all the years of research except 2012. Isolates of P. infestans from individual years were very similar to each other, as shown by Nei's genetic identity based on 14 SSR markers. The obtained results on isolate characteristics were analyzed in terms of meteorological data (air temperature and precipitation) and indicated that frost, long winters, and hot, dry summers did not directly affect the P. infestans population structure. We described the variability in metalaxyl resistance and virulence among isolates of the P. infestans genotype 34_A1.

Abstract
Objectives: Mechanical circulatory support for pediatric heart failure patients with the Berlin Heart EXCOR ventricular assist system is the only approved and established bridging strategy for recovery or heart transplantation. In recent years, the burden of thromboembolic events has led to modifications of the recommended antithrombotic therapy. Therefore, we aimed to assess modifications of antithrombotic practice among the European EXCOR Pediatric Investigator Group members. Methods: We sent a questionnaire assessing seven aspects of antithrombotic therapy to 18 European hospitals using the EXCOR device for children. Returned questionnaires were analyzed and identified antithrombotic strategies were descriptively compared to “Edmonton protocol” recommendations developed for the US EXCOR pediatric approval study. Results: Analysis of 18 received surveys revealed substantial deviations from the Edmonton protocol, including earlier start of heparin therapy at 6–12 h postoperatively and in 50% of surveyed centers, monitoring of heparin effectiveness with aPTT assay, administering vitamin K antagonists before 12 months of age. About 39% of centers use higher international normalized ratio targets, and platelet inhibition is changed in 56% including the use of clopidogrel instead of dipyridamole. Significant inter-center variability with multiple deviations from the Edmonton protocol was discovered with only one center following the Edmonton protocol completely. Conclusion: Current antithrombotic practice among European EXCOR users representing the treatment of more than 600 pediatric patients has changed over time with a trend toward a more aggressive therapy. There is a need for systematic evidence-based evaluation and harmonization of developmentally adjusted antithrombotic management practices in prospective studies toward revised recommendations.

Abstract
A diploid, potato mapping population consisting of 149 individuals was assessed in three consecutive years for important agronomic and quality traits: tuber shape, regularity of tuber shape, eye depth, mean tuber weight, and tuber flesh color. Analysis of variance showed that the genotype had the largest influence on the phenotypic scores but effect of the genotype × year interactions was also strong. Using this data and an existing genetic map, a quantitative trait loci (QTL) analysis was conducted. From four to seven QTL were detected for each trait except tuber flesh color, which was determined by a major QTL on chromosome III explaining 76.8% of the trait variance. Additionally, a minor QTL for flesh color was localized on chromosome II. For the other traits, significant QTL were detected: for tuber shape on chromosome X, for regularity of tuber shape on chromosome III, for eye depth on chromosome IV, and for tuber weight on chromosome I. Some detected QTL confirmed previous studies, but new ones were also identified.

Abstract
Initial experience of transcatheter aortic valve implantation (TAVI) or replacement (TAVR) has ap-peared as a promising minimally invasive technology for patients disqualified from surgical treatment (SAVR). Safety and efficacy of TAVI has been analyzed and assessed through numerous registries and trials. Furthermore, results obtained from comparative TAVI vs. SAVR trials proved that both treat¬ments can be considered equal in terms of post-procedural mortality and morbidity in high-risk, as well as lower risk patients. However, there are still some issues that have to be addressed, such as higher chance of paravalvular leakage, vascular injuries, conduction disturbances, malpositioning and the yet unmet problem of insufficient biological valves durability. Recent technological developments along with the learning curve of operators prove a great potential for improvement of TAVI and a chance of surpassing SAVR in various groups of patients in the near future. In pursuit of finding new solutions, the CardValve Consortium consisting of leading scientific and research institutions in Poland has been created. Under the name of InFlow and financial support from the National Center for Research and Development, they have started a project with the aim to design, create and implement into clinical practice the first, Polish, low-profile TAVI valve system, utilizing not only biological but also artificial, polymeric-based prosthesis. This review focuses on current developments in TAVI technologies including the InFlow project.

Abstract
Tuber tissue discolorations caused by impact (blackspot bruising) and enzymatic discoloration (ED) after tuber cutting are crucial quality traits of the cultivated potato. To understand the complex genetics of the traits, quantitative trait locus (QTL) analysis using diploid mapping population and diversity array technology (DArT) markers was performed. The phenotypic assessment included the complex evaluation of blackspot bruising susceptibility through two methods: rotating drum (BRD) and falling bolt (BFB) in combination with the evaluation of enzymatic discoloration. Because of observed in-practice relationship between bruising susceptibility and tuber starch content (TSC), analysis of starch content-corrected bruising susceptibility (SCB) was performed. QTLs for bruising were detected on chromosomes I, V with both test methods. The rotating drum method enabled the detection of additional QTLs on chromosomes VIII and XII. Analysis of SCB enabled the identification of the major QTL on chromosome V and two weaker QTLs on chromosomes VIII and XII, independently of starch content. The QTL for bruising detected on chromosome I overlapped with the most significant QTL for tuber starch content. This QTL was not significant for starch content-corrected bruising susceptibility, and the effect of the QTL on chromosome V was enhanced for this trait. The QTL analysis of ED revealed the contribution of seven QTLs for the trait, located on six chromosomes, including these detected for the first time: a major locus on chromosome V and minor QTLs on chromosomes VII and X, which were specific for the trait. The QTL for ED on chromosome VIII was co-localized with the marker for polyphenol oxidase (POT32). The phenotypic correlation between bruising and ED was confirmed in QTL analyses of both traits, and the QTLs detected for these traits overlapped on chromosomes I, V, and VIII. Our results should provide a basis for further studies on candidate genes affecting blackspot bruise susceptibility and enzymatic discoloration.
