Use of fine-needle puncture under endosonographic control in the diagnosis of left atrium sarcoma – case report

Background. Over the past 30 years, with the development of endoscopic technologies and the advent endoscopic ultrasound-guided fine-needle aspiration (EuS-FnA) it has become possible to diagnose with preliminary verification of cardiac tumors, which in turn is an undoubted advantage in detecting cardiac pathology. A rare clinical case is presented: the detection of a tumor of the left atrium using high-tech endoscopic techniques, in particular a EuS-FnA. when studying the surgical material using immunohistochemistry and FISH hybridization, the final diagnosis sounded like intimal sarcoma. Diagnosis of intimal sarcoma is a complex clinical task, and difficulties in making a diagnosis delay the duration of treatment. Our experience demonstrates the modern role of endoscopy as a minimally invasive method of diagnosing intracardiac tumors.
