Preoperative and postoperative examination. (A) Preoperative parasternal short-axis view at the level of the aortic valve showing the obstructed right ventricular outflow tract and pulmonary trunk. (B) Postoperative parasternal short-axis view at the level of the aortic valve showing the unobstructed right ventricular outflow tract and pulmonary trunk. (C) Computed tomography reveals the right ventricular outflow tract. (D) Computed tomography reveals the pulmonary trunk and right pulmonary artery. RVOT, right ventricular outflow tract; PA, pulmonary artery.

The pressure gradient from the pulmonary artery to the RV was 64 mmHg (Figure 1A). A filling deficit in the RV, pulmonary trunk, and right pulmonary artery was discovered by computed tomography (CT) (Figures 1C,D). She was discharged 7 days after surgery and the recovery time was uncomplicated. Following surgery, echocardiography showed an unobstructed RVOT (Figure 1B). Seven-year postoperative follow-up showed no recurrence of the patient's tumor.
Surgery pictures. Operative procedures. (A) Right ventricular outflow tract incision was made to expose the tumor. (B) and (C) The tumor root which attached to the membranous portion of interventricular septum was surgically removed. (D) The entire tumor.
