Primary left atrial rhabdomyosarcoma in a 42-year-old patient: an unusual cardiac tumor presentation

Left atrial rhabdomyosarcoma is an extremely rare and often overlooked form of primary cardiac malignancy that primarily affects the atria of the heart. The aggressive nature of atrial rhabdomyosarcoma necessitates early recognition, a comprehensive diagnostic workup, and prompt intervention to achieve the best possible outcomes. In this case report, we present the clinical details of a 42-year-old female diagnosed with left atrial rhabdomyosarcoma, who exhibited symptoms of recent pulmonary edema, weight loss, and alternating flushing. Diagnosis, surgical treatment, and the iatrogenic atrial septal defect complication due to interatrial septum invasion were discussed.
