The association of obesity with atrial fibrillation (AF) and with ventricular arrhythmias is well documented. The aim of this study was to investigate whether weight reduction by a laparoscopic sleeve gastrectomy has any effect on P wave dispersion (PWD), a predictor of AF, and corrected QT interval dispersion (CQTD), a marker of ventricular arrhythmias, in obese individuals. In a prospective study, a total of 114 patients (79 females, 35 males) who underwent laparoscopic sleeve gastrectomy were examined. The patients were followed 1 year. PWD and CQTD values before and 3rd, 6th, and 12th months after the surgery were calculated and compared. There was a statistically significant decline in body mass index (BMI), PWD, and CQTD values among baseline, 3rd, 6th, and 12th months (p < 0.001 for all comparisons). Correlation analysis showed a statistically significant correlation between Delta PWD and Delta BMI (r = 0.719, p < 0.001), Delta PWD and Delta left ventricular end-diastolic diameter (LVEDD) (r = 0.291, p = 0.002), Delta PWD and Delta left atrial diameter (LAD) (r = 0.65, p < 0.001), Delta CQTD and Delta BMI (r = 0.266, p = 0.004), Delta CQTD and Delta LVEDD (r = 0.35, p < 0.001), Delta CQTD and Delta LAD (r = 0.289, p = 0.002). In multiple linear regression analysis, there was a statistically significant relationship between Delta PWD and Delta BMI (beta = 0.713, p < 0.001), Delta PWD and Delta LVEDD (beta = 0.174, p = 0.016), Delta PWD and Delta LAD (beta = 0.619, p < 0.001), Delta CQTD and Delta BMI (beta = 0.247, p = 0.011), Delta CQTD and Delta LVEDD (beta = 0.304, p < 0.001), Delta CQTD and Delta LAD (beta = 0.235, p = 0.009). PWD and CQTD values of patients were shown to be attenuated after bariatric surgery. These results indirectly offer that there may be a reduction in risk of AF, ventricular arrhythmia, and sudden cardiac death after obesity surgery.
A Case of Mediastinal Mesenchymal Tumor Resembling Hemopericardium

Mediastinal neoplasms are rare in the elderly, and clinical suspicion is the first and most important step of differential diagnosis. Mediastinal tumors can be misdiagnosed because their symptoms or signs can overlap with cardiovascular diseases, which have a higher prevalence among the older population. The diagnostic process should be managed with multimodality imaging and clinical judgement. Here, the case of a 74-year-old male patient, who presented with shortness of breath, is examined. A chest X-ray revealed an increased cardiothoracic ratio, and he was diagnosed with hemopericardium following an emergent chest computed tomography. In the echocardiography, it was suspected that a hyperechogenic area adjacent to the heart might be due to a mass, and further examinations confirmed a mediastinal neoplasm. A surgical biopsy was performed, and it was determined to be a mesenchymal tumor. To conclude, clinicians should keep in mind the possibility of paracardiac neoplasm in the elderly, as well as in other age groups, when encountering mediastinal widening so that the patient can be protected from unnecessary interventions such as pericardiocentesis.

OBJECTIVES: Since many similar mechanisms may play a role in the pathophysiology of sarcoidosis and atherosclerosis, the risk of subclinical atherosclerosis may be increased in patients with sarcoidosis. The aim of this study was to evaluate known markers of subclinical atherosclerosis, namely epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) in patients with sarcoidosis. MATERIALS AND METHODS: This cross-sectional study included a total of 183 subjects, including 94 patients with sarcoidosis (patient group) and a control group of 89 healthy individuals. Measurements of EFT and CIMT were taken from all subjects and recorded. The groups were compared, and differences were analyzed statistically. RESULTS: EFT was higher in patients than in control subjects (6.42 +/- 1.12 mm vs 7.13 +/- 1.41 mm, p<0.001). CIMT was higher in patients than in control subjects (0.51 +/- 0.02 mm vs 0.52 +/- 0.02 mm, p=0.003). CONCLUSION: EFT and CIMT were found to be higher in patients with sarcoidosis than in healthy people. These results indicate that the risk of subclinical atherosclerosis might be increased in these patients.
