Atrial Flutter Ritmi ile Birlikte Görülen Büyük Sa¤ Atrial Miksoma

Özet

22 yaflnda erkek hasta solunum sknts ile acil servisimize baflvurdu. Fizik muayenesinde, dispne ve ortopne saptand. Elektrokardiyografisinde (EKG) atrial flutter ritmi gözlendi. Transtorasik ekokardiografisinde sa¤ atriuma yerleflmifl ve interatrial septumdan kaynaklanan bir kitle görüldü. Operasyon srasnda orta dereceli hipotermi uygulanarak sa¤ atriumdaki kitle baflarl bir flekilde çkartld. 15 x 3 cm çapndaki kitlenin histolojik incelemesi atrial miksoma olarak de¤erlendirdi. Cerrahi olarak çkartlmasndan 12 ay sonra, klinik ve ekokardiografik takiplerinde yeterli egzersiz tolerans, EKG'de sinüs ritmi ve normal snrlar içinde kardiyak fonksiyonlar gözlendi.

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.
