Objective: Cardiac thromboses are not uncommon, but right atrial thromboses are extremely rare. Methods: This study is a systematic study. 1541 articles were analyzed based on keywords and according to pubmed, scopus, web of science and embase databases. After removing duplicates, 964 articles remained. Finally, after reviewing the articles according to the title and abstract, 906 articles were removed and only 58 articles were included in the study and analyzed. Results: After the investigations, the results showed that in the studies, surgical treatments and anticoagulation and thrombolysis treatments were used to treat patients. Discussion: Finally, according to the data obtained from this study, it has been shown that the use of anticoagulation and thrombolysis treatment methods compared to surgical treatment for the treatment of patients can be associated with fewer complications for them. The use of surgery as the first treatment option can be combined with the use of antibiotics to prevent infection in patients. Therefore, the type of treatment can be chosen based on the clinical process and clinical symptoms of the patients.
