Final answer:
Chest X-ray findings for a large VSD include an enlarged heart and prominent pulmonary arteries, indicative of the increased blood flow and pressure changes within the heart and lungs.
Step-by-step explanation:
The subject of the question relates to the chest X-ray findings associated with a large ventricular septal defect (VSD). On a chest X-ray, a large VSD can present with various findings, such as an enlarged cardiac silhouette due to left ventricular hypertrophy, pulmonic arterial prominence because of increased blood flow, or changes in the lung fields that might suggest pulmonary edema. These findings are indicative of the significant hemodynamic changes caused by a large VSD.
