Case 1
A 13-year-old female patient (height:150 cm; weight: 42 kg) was diagnosed with functional SV combined with transposition of the great arteries (TGA) with a right position of the aorta based onultrasound findings at the age of 3, but did not receive any treatment. In 2017, she came to our hospital due to numbness in both lower limbs and dyskinesia. Thoracic magnetic resonance imaging (MRI) showed a space-occupying lesion in the spinal canal. A bone biopsy was performed and revealed cavernous hemangioma. This patient underwent a tumor resection at another hospital and returned to our hospital for radiotherapy 5 months after the operation.
Physical examination at our hospital showed a temperature of 36.5℃, a pulse of 80 beats/min, no difference in the pulse and heart rate (HR), a respiratory rate of 18 breaths/min, and a blood pressure of 120/80 mmHg.Other pertinent examinations showed no signs of anemia and she had no history of hemoptysis, syncope, or long-term high fever. The patient exhibited normal development, moderate nutrition, and a clear mind. Her New York Heart Association functional class was II. Echocardiography revealed the following: the heart was located in the left thoracic cavity, the atrium was in the normal position, the left ventricular cavity was the main cavity, and the right ventricular cavity was the residual cavity. The pulmonary artery (PA) was locatedon the posterior sideand arose from the autonomous cavity. The aorta was moderately developed, located on the anterior sideand arose from the self-mutilating cavity. Echocardiography at the upper interventricular septum was interrupted by 22.3 mm(Figure 1). Color Doppler flow imaging (CDFI) revealed a two-way low-resistance shunt in the ventricular septal defect. The patient was diagnosed with the following diseasesbased on the echocardiography results: congenital heart disease, functional SV, TGA, mild PS, left ventricular hypertrophy, and left atrial enlargement. Further examination was recommended. No tumor metastasis was found after radiotherapy at our hospital and the prognosis was appreciable.
