ABSTRACT

A 22 year-old man presented to the emergency unit with the complaint of difficulty in breathing. In the physical exam, dyspnea and orthopnea were found. In the electocardiographic exam (ECG) atrial flutter rhythm was seen. The transthoracic echocardiographic exam revealed a large atrial mass that was originating from interatrial septum. During surgery, complete surgical removal of the right atrial mass was successfully performed under moderate hypothermia. Histological investigations revealed a mass of 15 x 3 cm in diameter and the pathological examination showed that the lesion is a myxoma. Twelve months after surgical excision, clinical and echocardiographical follow-up showed a satisfactory exercise tolerance, sinus rhythm in ECG exam, and cardiac functions within normal limits.

Key Words: Right atrial myxoma; atrial şutter

ÖZET

22 yaşında erkek hasta solunum sıkıntısı ile acil servisimize başvurdu. Fizik muayenesinde, dispne ve ortopne saptandı. Elektrokardiyografisinde (EKG) atrial flutter ritmi gözlendi. Transtorasik ekokardiografisinde sağ atriuma yerleşmiş ve interatrial septumdan kaynaklanan bir kitle görüldü. Operasyon sırasında orta dereceli hipotermi uygulanarak sağ atriumdaki kitle başarılı bir şekilde çıkartıldı. 15 x 3 cm çapındaki kitlenin histolojik incelemesi atrial miksoma olarak değerlendirdi. Cerrahi olarak çıkartılmasından 12 ay sonra, klinik ve ekokardiografik takiplerinde yeterli egzersiz toleransı, EKG'de sinüs ritmi ve normal sınırlar içinde kardiyak fonksiyonlar gözlendi.
