Background: Heterotopic pancreas is defined as pancreatic tissue located outside the pancreatic parenchyma that lacks an anatomic or vascular connection to the normal pancreas. Symptomatic gastric heterotopic pancreas is a rare condition that can manifest as acute or chronic pancreatitis. Asymptomatic heterotopic pancreas does not require treatment, while symptomatic lesions should be resected.

- * In a review of 755 patients, the study found a 25% prevalence of SVT in those with isolated pre-capillary PH (Ipc-PH) and significantly higher rates (51%) in those with combined post- and pre-capillary PH (Cpc-PH). Atrial fibrillation was the most common type of SVT.
- * The study concluded that SVT is quite common in PH patients, particularly in those with elevated post-capillary pressure, but having SVT did not correlate with

Background And Aims: Colonoscopy with polypectomy are associated with a reduction in the incidence of colorectal cancer (CRC), as well as mortality, secondary to CRC. Because of the variation in physicians' performance and the risk of interval CRC after a colonoscopy, several quality indicators have been established. ADR (adenoma detection rate) is a generally accepted quality indicator.

Three stages of cardiac involvement are usually described. Initially, myocardial inflammation occurs, that can continue with a thrombotic stage and eventually progress to the last irreversible stage called endomyocardial fibrosis, which represents one of the acquired forms of restrictive cardiomyopathy.

Their prevalence and impact on prognosis of patients are not known. We analysed the prevalence of AF/AT and the clinical outcome in 197 patients with CTEPH treated with PEA (median age 62; interquartile range 53-68 years; 62% males).

Article Synopsis
- The registry aimed to evaluate the effects of riociguat on clinical outcomes and quality of life in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who could not undergo surgery or had surgery that did not fully resolve their condition.
- The study collected retrospective data from 51 patients over a period of approximately 5 months and 1 year after starting riociguat, noting improvements in walking distance, quality of life scores, and self-assessment of health status.
- Results showed significant health improvements and good tolerability for riociguat, with an 89.1% annual survival rate, indicating its effectiveness in real-world clinical settings.
Magnetic resonance is becoming an increasingly used examination in cardiology, since it greatly improves the accuracy of diagnosing of many heart diseases. At present magnetic resonance is the gold standard in assessing the volumes of the heart chambers and the systolic function of both ventricles. The possibility of detecting tissue characteristics to refine the diagnostics of different types of myocardial pathology is of essential importance.

- Magnetic resonance imaging (MRI) is increasingly used in cardiology for more accurately diagnosing heart diseases, particularly assessing heart chamber volumes and ventricular function.
- The article provides an overview of how MRI helps diagnose various myocardial conditions, such as cardiomyopathy and myocarditis, by detecting tissue characteristics.
- It specifically details the advantages of MRI in different types of cardiomyopathies, including dilated, hypertrophic, and arrhythmogenic right ventricular cardiomyopathy.
