NADİR KARDİYAK TÜMÖR: ATRİYAL MİKSOMANIN TOMOGRAFİ İLE TANI VE YÖNETİMİ

Atrial myxomas are the most common benign primary cardiac tumors, predominantly located in the left atrium and frequently diagnosed between the ages of 30 and 60, with a higher prevalence in women. Although often asymptomatic, these tumors can present with various symptoms, including dyspnea, palpitations, and systemic embolic events, depending on their size, location, and mobility. We report the case of a 62-year-old female patient with a left atrial myxoma, presenting with mild dyspnea and palpitations. The patient’s past medical history included hypertension and type 2 diabetes, with no prior history of cardiovascular disease. Initial transthoracic echocardiography (TTE) revealed a pedunculated mass in the left atrium, partially obstructing the mitral valve opening. Contrast-enhanced computed tomography (CT) further confirmed the diagnosis of atrial myxoma. Surgical resection was performed successfully, with histopathological confirmation of the myxoma. Postoperative imaging showed no residual mass, and the patient’s symptoms resolved entirely. This case underscores the importance of prompt diagnosis and surgical intervention in atrial myxoma cases to prevent potential embolic complications and hemodynamic deterioration. Early surgical removal offers an excellent prognosis, minimizing the risk of recurrence. Regular follow-ups remain essential to monitor for potential recurrence, although rare. This case emphasizes the role of echocardiography and CT in the diagnostic process and highlights the favorable outcome achievable with early intervention in atrial myxoma cases.
