Introduction

Infective endocarditis (IE) is still connected with high operative mortality. Inflammatory markers are commonly used in monitoring patient clinical condition. Respiratory burst and reactive oxygen species (ROS) are the main way of pathogen elimination. Specificity of this process in the aspect of bacterial infection is the key for correlation assessment between ROS and inflammatory markers in patients with IE. In the study, assessment of ROS as a clinical indicator in IE was conducted.

Material and methods

During 2007/2008 in the Cardiosurgical Clinic of the Medical University in Lodz there were 20 patients operated on for IE. The examined population consisted of 13 men and 7 women, aged from 23 to 74 years. Inflammatory markers – leukocytosis (WBC), C-reactive protein (CRP), procalcitonin (PCT) and erythrocyte sedimentation rate (ESR) – were assessed preoperatively, on the 3rd, 7th, 12th and 21st day. Simultaneously, with the second venous blood sample chemiluminescence (luminal enhanced whole blood chemiluminescence) was carried out and used to assess ROS production. The results were analyzed statistically.

Results

Positive correlation between ESR, CRP and ROS in the preoperative period was confirmed. An increase in ROS and a statistically significant increase in inflammatory markers on the 3rd day were observed. The ROS normalized on the 12th day. Marked individual variability was specific for the inflammatory markers. Despite the significant decrease, not all of them achieved a normal level at the last control point.

Conclusions

Assessment of ROS seems to be a universal parameter with possible application in patients with IE.

Intracardiac fistulas are rare complications of infective endocarditis. We report an unusual case of successful surgical repair of intracardiac fistula between the left ventricle and the left atrium in the course of infective endocarditis in a 20-year-old patient. According to this we conclude that timely diagnosis, proper antibiotic treatment, and early surgical intervention should improve the outcomes of infective endocarditis complications.

The heart is the rarest site for neoplasms to be localized. Despite modern diagnostic techniques, cardiac tumours continue to among those discovered latest and with the worst prognoses. We present the case of a 62-year-old woman with a heart tumour and mediastinal lymphadenopathy, who was admitted to the Department of Cardiac Surgery. The patient underwent surgical removal of the tumour with extracorporeal circulation. The left atrium, mitral valve and the left ventricle were occupied by the infiltration. A radical resection appeared to be impossible. A valvular prosthesis was not implanted. The perioperative period was uncomplicated. On the 9th day a local recurrence was confirmed in the transthoracic echocardiography. Further oncological diagnostics revealed the spread of the malignant neoplasm to bones of the pelvis and spine. Chemotherapy was initiated. The authors discuss the most appropriate diagnostic and treatment procedures employed in the above case.

Introduction

The aim of the study was to analyse the risk factors of early and late mortality in patients undergoing the first reoperation for prosthetic valve dysfunction.

Material and methods

A retrospective observational study was performed in 194 consecutive patients (M = 75, F = 119; mean age 53.2 ±11 years) with a mechanical prosthetic valve (n = 103 cases; 53%) or bioprosthesis (91; 47%). Univariate and multivariate Cox statistical analysis was performed to determine risk factors of early and late mortality.

Results

The overall early mortality was 18.6%: 31.4% in patients with symptoms of NYHA functional class III-IV and 3.4% in pts in NYHA class I-II. Multivariate analysis identified symptoms of NYHA class III-IV and endocarditis as independent predictors of early mortality. The overall late mortality (> 30 days) was 8.2% (0.62% year/patient). Multivariate analysis identified age at the time of reoperation as a strong independent predictor of late mortality.

Conclusions

Reoperation in patients with prosthetic valves, performed urgently, especially in patients with symptoms of NYHA class III-IV or in the case of endocarditis, bears a high mortality rate. Risk of planned reoperation, mostly in patients with symptoms of NYHA class I-II, does not differ from the risk of the first operation.

Systemic lupus erythematosus is a chronic inflammatory autoimmune disease which damages tissue and organs. Circulation, kidney, lungs, liver, central and peripheral nervous systems, joints and skin may be damaged. It also often involves psychotic syndromes which might even be stimulated by glucocorticoid therapy. In the following article we present the case report of psychotic symptoms in a 26-year old patient after management of aortic stenosis in systemic lupus erythematosus receiving glucocorticoid therapy.
