Belonging to the normal oral, gastrointestinal, and urogenital flora, Abiotrophia defectiva is responsible for 1–2 % of all infective endocarditis (IE) cases. The manifestation of A.defectiva endocarditis may by atypical, without fever. Difficult to isolate pathogen requires special culture media. A 45-year-old female was admitted due to anemia and progressive weight loss (8 kg in 6 months). She had a history of benign mitral valve (MV) prolapse and non-stenotic bicuspid aortic valve (BAV). In echocardiography, large vegetations on MV and small vegetation on BAV were found. An enriched medium for fastidious pathogens was used. A. defectiva was identified using biochemical analysis with VITEK-2 Compact. In the fourth week of antibiotic therapy, she required urgent MV replacement due to MV regurgitation progression while vegetation on BAV disappeared. Although patient's frailty and underweight caused prolonged postoperative wound healing, she was transferred to rehabilitation in good conditions. No relapse of IE was observed during five-month follow-up.

Background: Coronary heart disease is the most common cause of death worldwide. It is responsible for almost a third of deaths in patients over the age of 35. Various biomarkers are currently being studied in detail for their value in predicting postoperative mortality in patients undergoing CABG. Aim: The aim of this study is to analyze the predictive value of certain blood morphological parameters in CABG and off-pump coronary artery bypass grafting (OPCAB). Methods: A total of 520 patients who underwent surgery in two consecutive years and underwent CABG (404) or OPCAB (116) were included in this retrospective study. Gender, age, comorbidities, five-year survival rate, detailed information on hospitalization, surgery, intensive care unit parameters and preoperative blood samples from the cubital vein were recorded. Inverse propensity treatment weighting was applied to adjust for confounding factors at baseline. Results: No differences were found between OPCAB and CABG as an isolated comparison. In the standardized population, patients with abnormal lymphocyte counts had an increased risk of death at one-year and five-year follow-up. In the standardized population, abnormal red blood cell distribution width (RDW-SD), neutrocyte-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were associated with increased mortality in each period analyzed. Conclusions: Abnormal PLR, RDW-SD and NLR are associated with increased early and late mortality in patients undergoing CABG and OPCAB. Abnormal lymphocytes are only associated with increased late mortality.

Background: The presence of locomotive disorders may negatively impact the outcome of cardiac surgeries. This retrospective study aimed to assess the effect of preoperative diagnosis of locomotive disorders requiring the continuous use of orthopedic devices on postoperative rehabilitation and stable sternum adhesion.
Material and methods: The study included 122 patients who underwent cardiac surgery, with 68 patients in the study group having a musculoskeletal disorder and 54 patients in the control group without such disorders. Preoperative demographic, clinical, and laboratory data as well as postoperative rehabilitation and sternum adhesion were evaluated. Results: The results showed that patients in the study group had lower levels of calcium (p < 0.001), vitamin D (p < 0.001), and creatine kinase (p = 0.022) prior to the surgery. In the early postoperative period, 8 patients from the study group and 4 from the control group required reoperation due to sternal instability (p = ns). In the late postoperative period, sternal instability was present in 2 patients from the study group and 3 from the control group (p = ns). The survey study revealed a significantly better (p = 0.029) evaluation of postoperative rehabilitation among the study group patients.
Conclusions: Overall, the results indicated that a preoperative locomotive disorder has no significant impact on sternal instability in the early or late postoperative periods. However, patients with such disorders have a better understanding of the importance, purpose, and course of rehabilitation after cardiac surgery and exhibit lower levels of calcium, vitamin D, and creatinine.

Background: The incidence of thoracic aortic aneurysms is estimated at 3.0–8.3/100,000 persons per year. There is a lack of reports in the literature on the outcomes of small- and medium-sized thoracic endovascular aortic repairs. The aim of this study is to present the results of thoracic endovascular aortic repairs at a single medium-sized center performed exclusively by a cardiac surgeon. Methods: Ninety patients who had undergone aortic stent graft implantations for the treatment of thoracic aortic anomalies were comprehensively, retrospectively evaluated. The detailed preoperative, surgical, and postoperative parameters of the patients, including the survival rate up to five years, were recorded and further analyzed. Results: The patients’ Euroscores were four (2.1–9). The 30-day mortality rate was 8.9%, the 1-year mortality rate was 15.6%, and the 5-year mortality rate was 38.9% for all causes. Postoperative complications were observed in 10% of the patients. Statistically significant differences were observed between the urgency of surgery at 30 days and survival at one year, but not at five years. The most common complications were related to respiratory (4.4%), renal (3.3%), and neurological (3.3%) dysfunction. Conclusions: Thoracic endovascular aortic repair can be safely performed in small- and medium-sized centers with optimal long-term results.

Aim. Clostridioides difficile (CDI) poses a significant threat to postoperative cardiac surgery patients. This study examines the impact of specific pre-, intra-, and post-operative factors, along with geographical considerations, on Clostridioides difficile (CD) incidence and its consequences. The study aims to identify factors contributing to increased CD prevalence in cardiac surgery units. Material and methods. A single-centre cohort of 3502 patients undergoing surgical myocardial revascularisation between January 2013 and March 2018 was analysed, with 48 diagnosed with CDI. Preoperative risk factors include the use of broad-spectrum antibiotics, advanced age, comorbidities, and prolonged hospital stays. Intraoperatively, attention is given to catheter-related issues, mechanical ventilation, and the use of blood products. Postoperatively, the study assesses CDI's impact on recovery, complications, and outcomes. A geographical analysis explores regional variation in CDI incidence. Results. Results indicate a CDI incidence of 1.37%, aligning with existing literature trends. Demographically matched controls show no significant differences in age, gender, or location. Higher Body Mass Index and lower left ventricular ejection fraction are identified as significant risk factors. Laboratory findings indicate elevated CRP levels and increased platelet count associated with CDI. Postoperative CDI significantly prolongs hospitalisation time. EuroSCORE II values are higher in the CDI group, though not statistically significant. Conclusions. The study offers a comprehensive understanding of CDI dynamics in cardiac surgery, emphasising the need for tailored preventive measures. Specific risk factors and regional variations underscore the importance of vigilant monitoring and early intervention. Future research should include larger cohorts and explore gut microbiota for refined strategies. In the later part of the abstract the authors use the abbreviation CDI. We suggest replacing this abbreviation with CDI.
