Left Ventricular Outflow Obstruction due to a Left Ventricular Myxoma

Once it is diagnosed, immediate surgical extirpation is desirable for treating left ventricle myxoma that's accompanied with stenosis of the left ventricle outflow tract. This is because this condition may potentially induce fatal complications such as cerebral infarction or myocardial infarction that's triggered by myxoma embolus, or even sudden death due to coronary malperfusion. An 18-year-old male with the chief complaint of NYHA class II exertional dyspnea was found to have a $4{\times}3\;cm^2$ sized mass on transthoracic ultrasonography, which was shown to move down the left ventricle outflow tract on the systolic phase. The mass was immediately extirpated by incision of the left ventricle; the mass was finally diagnosed as a myxoma. The patient was discharged on at the 10th day postoperatively without any complications. On the 22-month follow-up observation made at the out-patient clinic after discharge, there have been no noticeable, significant changes seen on physical examination or the cardiac ultrasonography.

좌심실 점액종에 의해 발생한 좌심실 유출로 협착증

좌심실 유출로 협착을 동반한 좌심실 점액종은 점액종 색전에 의한 뇌경색, 심근경색 등의 치명적인 합병증을 유발할 수도 있고 돌연사의 위험성도 있어 진단되면 조기에 외과적으로 적출하는 것이 바람직하다. NYHA II의 운동성 호흡곤란을 주소로 내원한 18세 남자 환자가 경흉부 초음파상 심 수축기에 좌심실 유출로를 협착하는 $4{\times}3\;cm^2$ 크기의 좌심실내 종양이 발견되어 좌심실 절개를 통한 적출술을 받았다. 술 후 점액종으로 확진되었으며 환자는 10일째에 합병증 없이 퇴원하였다. 현 22개월째 외래 추적관찰 중인데 이학적 소견이나 심초음파 검사상에서 특이 사항은 관찰되지 않고 있다.
