Left Ventricular Outflow Obstruction due to a Left Ventricular Myxoma / 대한흉부외과학회지

ABSTRACT

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 4x3 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.
