The current clinical practice for management of post-infarction ventricular septal rupture: a European survey.

Aims: Many historical and recent reports showed that post-infarction ventricular septal rupture (VSR) represents a life-threatening condition and the strategy to optimally manage it remains undefined. Therefore, disparate treatment policies among different centres with variable results are often described. We analysed data from European centres to capture the current clinical practice in VSR management. Methods and results: Thirty-nine centres belonging to eight European countries participated in a survey, filling a digital form of 38 questions from April to October 2022, to collect information about all the aspects of VSR treatment. Most centres encounter 1-5 VSR cases/year. Surgery remains the treatment of choice over percutaneous closure (71.8% vs. 28.2%). A delayed repair represents the preferred approach (87.2%). Haemodynamic conditions influence the management in almost all centres, although some try to achieve patients stabilization and delayed surgery even in cardiogenic shock. Although 33.3% of centres do not perform coronarography in unstable patients, revascularization approaches are widely variable. Most centres adopt mechanical circulatory support (MCS), mostly extracorporeal membrane oxygenation, especially pre-operatively to stabilize patients and achieve delayed repair. Post-operatively, such MCS are more often adopted in patients with ventricular dysfunction. Conclusion: In real-life, delayed surgery, regardless of the haemodynamic conditions, is the preferred strategy for VSR management in Europe. Extracorporeal membrane oxygenation is becoming the most frequently adopted MCS as bridge-to-operation. This survey provides a useful background to develop dedicated, prospective studies to strengthen the current evidence on VSR treatment and to help improving its currently unsatisfactory outcomes.

Toxoplasma Gondii Serostatus in Heart Transplant Recipients: Is It an Independent Prognostic Factor?

INTRODUCTION AND OBJECTIVES: To assess the potential association between recipient Toxoplasma gondii serostatus and outcomes after heart transplant (HT). METHODS: We conducted a retrospective single-center study of 657 HT recipients from 1991 to 2015. Survival and the incidence of adverse clinical events of T. gondii-seropositive (n = 481) vs T. gondii-seronegative (n = 176) recipients were compared by means of 2 different multivariable Cox regression models. Model 1 included solely age and sex, and model 2 included other potential confounders. RESULTS: Over a median follow-up of 2903 days (interquartile range: 898-4757), 250 seropositive recipients (52%) and 72 seronegative recipients (41%) died. Univariable analysis showed increased posttransplant mortality among T. gondii-seropositive recipients (hazard ratio [HR] = 1.31; 95% confidence interval [95%CI], 1,00-1.70). After multivariable adjustment, the statistical significance of this association was lost (model 1: HR = 1.09; 95%CI, 0.83-1.43; model 2:HR = 1.12; 95%CI, 0.85-1.47). Recipient T. gondii seropositivity was independently associated with an increased risk of acute rejection (model 1: HR = 1.36; 95%CI, 1.06-1.74; model 2: HR = 1.29; 95%CI, 1.01-1.66). Multivariable models showed no statistically significant impact of recipient T. gondii serostatus on the incidence of infection, malignancy, coronary allograft vasculopathy, or the composite outcome of cardiac death or retransplant. No significant association was found between donor-recipient T. gondii serostatus matching and posttransplant outcome. CONCLUSIONS: In this study, recipient T. gondii serostatus was not an independent predictor of long-term post-HT outcome.

Lower limb overflow syndrome in extracorporeal membrane oxygenation.

Peripheral extracorporeal membrane oxygenation (ECMO) is associated with a not negligible rate of vascular morbidity. Most vascular complications are related to limb ischaemia mainly due to insufficient limb perfusion or embolic events. To the best of our knowledge, this is the first report of a severe epidermolysis and overflow syndrome as a result of an overperfusion phenomenon through an unknown femoral arterio-venous fistula in a patient requiring ECMO support.

[Persistent candidemia in a renal-pancreatic transplant patient]. / Candidemia persistente en una paciente receptora de trasplante renopancreático.

BACKGROUND: In recent decades, there has been an increase in the survival of recipients of solid organ transplants related to the improvement of the surgical technique, the introduction of protocols for immunosuppressive therapy, and the use of antimicrobial prophylaxis. Nonetheless, invasive fungal infection (IFI) is currently the major cause of morbidity and mortality in this group of patients. Invasive candidiasis is the most common IFI found after renal transplantation and is usually associated with total parenteral nutrition, broad-spectrum antibiotic therapy and abdominal surgery. CLINICAL CASE: We report the case of a recent kidney-pancreas transplant recipient who developed a persistent catheter-related candidemia caused by Candida glabrata. The patient was treated with anidulafungin and had a good clinical course with no significant drug interactions. We discuss the possible causes and diagnostic and therapeutic alternatives of this kind of infection.
