INTRODUCTION: It is hypothesized that systemically administered antibiotics penetrate wound sites more effectively during negative pressure wound therapy (NPWT). However, there is a lack of clinical data from patients who receive NPWT for deep sternal wound infection (DSWI) after open-heart surgery. Here, we evaluated vancomycin penetration into exudate in this patient group. PATIENTS AND METHODS: For this prospective observational study, we enrolled 10 consecutive patients treated with NPWT for post-sternotomy DSWI. On the first sampling day, serum and exudate samples were synchronously collected at 0 (pre-dose), 0.5, 1, 2, 3 and 6 h after vancomycin administration. On the following three consecutive days, additional samples were collected, only before vancomycin administration. RESULTS: The ratio of average vancomycin concentration in wound exudate to in serum was higher for free (unbound) (1.51 ± 0.53) than for total (bound + unbound) (0.91 ± 0.29) concentration (p = 0.049). The percentage of free vancomycin was higher in wound exudate than serum (0.79 ± 0.19 vs. 0.46 ± 0.16; p = 0.04). Good vancomycin wound penetration was maintained on the following three days (vancomycin trough exudate-to-serum concentration ratio > 1). The total hospital stay was significantly longer in patients with DSWI (46 ± 11.6 days) versus without DSWI (14 ± 11.7 days) (p < 0.001). There was no in-hospital or 90-day mortality. Two patients experienced late DSWI recurrence. All-cause mortality was 4.8% during a median follow-up of 2.5 years. CONCLUSION: Vancomycin effectively penetrates wound exudate in patients receiving NPWT for DSWI after open-heart surgery.The protocol for this study was registered at ClinicalTrials.gov on July 16, 2024 (NCT06506032).

BACKGROUND Traumatic thoracic aortic transection is one of the most severe complications of high-energy injuries, but patients rarely receive treatment, and it is fatal in the vast majority of cases. Due to the complexity of surgical revision for transection, endovascular repair with stent graft implantation is the preferred approach. MATERIAL AND METHODS We retrospectively analyzed the short-term and long-term treatment results for 31 patients (29 men, 2 women) treated at the Interventional Radiology Department, University Hospital Ostrava, for the isthmus part of a descending thoracic aorta injury between 2004 and 2020. RESULTS The median patient age was 48 years (interquartile range [IQR]: 28-63 years). The most common causes of injury were traffic accidents and falls or jumps, with the trauma location at the Ishimaru zones 2 to 4 of the aortic isthmus. Aortic stent grafts were successfully implanted in all patients; 13% of patients had complications and 10% died due to the trauma severity. The median procedure duration was 30 min (IQR: 25-43 min) and the median hospital stay was 29 days (IQR: 28-63 days). CONCLUSIONS Aortic stent graft implantation appears to be a safe and effective method for dealing with thoracic aorta injury, with a low complication rate and high patient survival. The endovascular approach is the method of choice for treating this severe disease, and a multidisciplinary approach for emergency medical treatment with a comprehensive trauma protocol is essential.

AIMS: Limited contemporary data are available on the clinical and echocardiographic outcomes after surgery for cardiac papillary fibroelastoma (CPF). The aim of this study was to review the clinical manifestations, pathological characteristics, surgical management, and prognoses of patients with histologically verified CPF, who underwent surgery at our cardiac surgery center from 2008 to 2018. METHODS AND RESULTS: Twelve patients of median age 62 years (28 to 77 years) were treated. Embolic stroke or transient ischemic attack (five patients, 42%) were the only CPF clinical manifestations. Eleven (92%) tumors were localized on the valves, with the aortic valve being the most common tumor site (seven patients; 58%). Multiple factor analysis revealed no independent predictor of CPF-related embolization. Simple shave tumor excision was sufficient in most patients (10 patients, 83%). No operative or tumor-related late mortality during the median follow-up period of 4.7 years (1.1 to 10.2 years) was recorded. Asymptomatic metachronous valve tumor recurrence (in a location different from that of the original tumor) was revealed in two patients (17%) by transesophageal echocardiography (TEE), not detected by transthoracic echocardiography (TTE). One of these two patients underwent repeated surgery for CPF but later suffered a recurrent embolic stroke, due to another tumor recurrence. CONCLUSION: CPF can be safely and effectively treated surgically. TEE is superior to the TTE option in CPF post-operative recurrence detection. There is a clear need for a prospective study to determine criteria for embolization risk stratification and optimum management in patients with CPF.

INTRODUCTION: The β1 adrenergic receptor blocker metoprolol is often prescribed together with the antiarrhythmic drug propafenone. Both are metabolized by cytochrome P450 2D6 and propafenone is also an inhibitor of this enzyme. We present a pediatric case showing metoprolol and propafenone intoxication in combination. CASE: A 14-year-old girl was admitted to a local emergency department after ingestion of metoprolol (probably 1g) and propafenone (probably 1.5-3g) in a suicide attempt. She developed cardiogenic shock with cardiac arrest and was fully resuscitated. Veno-arterial femorofemoral extracorporeal membrane oxygenation was started immediately. High serum levels of both drugs were detected approximately 10h after ingestion (2630ng/mL metoprolol and 2500ng/mL propafenone). Other serial samples for the monitoring of the levels of metoprolol and its metabolite alfa-hydroxymetoprolol were obtained between days 2 and 4 after admission. The metoprolol/alfa-hydroxymetoprolol ratio on the 2nd day was 36.1, indicative of a poor metabolizer phenotype. The elimination half-life of metoprolol was prolonged to 13.2h and the clearance decreased by about 70%. The patient condition gradually worsened, brain edema and intracerebral hemorrhage occurred, and on the 6th day, the patient died. CONCLUSION: We document a pediatric case report of death due to a mixed drug overdose of metoprolol and propafenone, along with data regarding serum metoprolol, alfa-hydroxymetoprolol, and propafenone levels.

BACKGROUND: There are limited contemporary data on the safety and efficacy of echo-guided pericardiocentesis following cardiac surgery in Europe. The aim of the study was to review tertiary cardiac surgery center experience with postoperative pericardial effusion (PE) diagnosis and treatment. METHODS: A total of 6830 patients underwent open-heart surgery at our center between December 2004 and November 2016. Of these patients, 208 (3%) required pericardiocentesis for significant PE. RESULTS: There was a significant reduction of the incidence of substantial PE requiring pericardiocentesis by use of alternative surgical pericardial cavity drainage system (the accessory Redon drain positioned along the diaphragmatic surface of the heart) compared to conventional retrosternal chest tube drainage (3.3% vs. 2.1%). The rate/relative risk of pericardiocentesis was significantly higher after valve surgery, aortic root and ascending aorta surgery, and surgical ablation of atrial fibrillation-i.e. among patients who had received postoperative anticoagulation therapy. Clinical manifestations of cardiac tamponade were observed in 36% of patients, while progressive large PE without tamponade was evacuated in 41% of patients. Initial echo-guided pericardiocentesis was therapeutically effective in 98.6% of cases, and the rate of major complications was 1%. There was no mortality related to pericardiocentesis. Eighteen patients (8.7%) required repeated pericardiocenteses due to recurrent effusion. Fifteen patients (7.2%) in the pericardiocentesis group required surgery due to recurrent effusion, persistent bleeding, or clotted hemopericardium. CONCLUSIONS: Echo-guided pericardiocentesis was very effective and safe method for primary treatment of postoperative PE. Most patients did not require further intervention after this treatment.

Here, we examined whether intraoperative sonolysis can alter the risk of new ischemic lesions in the insonated brain artery territory during coronary artery bypass grafting (CABG) or valve surgery.Silent brain ischemic lesions could be detected in as many as two-thirds of patients after CABG or valve surgery.Patients indicated for CABG or valve surgery were allocated randomly to sonolysis (60 patients, 37 males; mean age, 65.3 years) of the right middle cerebral artery (MCA) during cardiac surgery and control group (60 patients, 37 males; mean age, 65.3 years). Neurologic examination, cognitive function tests, and brain magnetic resonance imaging (MRI) were conducted before intervention as well as 24 to 72 hours and 30 days after surgery.New ischemic lesions on control diffusion-weighted MRI in the insonated MCA territory ≥0.5 mL were significantly less frequent in the sonolysis group than in the control group (13.3% vs 26.7%, P = 0.109). The sonolysis group exhibited significantly reduced median volume of new brain ischemic lesions (P = 0.026). Stenosis of the internal carotid artery ≥50% and smoking were independent predictors of new brain ischemic lesions ≥0.5 mL (odds ratio = 5.685 [1.272-25.409], P = 0.023 and 4.698 [1.092-20.208], P = 0.038, respectively). Stroke or transient ischemic attack occurred only in 2 control patients (P = 0.496). No significant differences were found in scores for postintervention cognitive tests (P > 0.05).This study provides class-II evidence that sonolysis during CABG or valve surgery reduces the risk of larger, new ischemic lesions in the brain.www.clinicaltrials.gov (NCT01591018).
