Parents deny any recent febrile illness. Chest radiograph demonstrates cardiomegaly and the electrocardiogram is notable for a QR pattern, ST segment depression, and T-wave inversion in leads I, II, and aVL. A transthoracic echocardiogram reveals severe left atrial dilation, severe mitral regurgitation, and left ventricular dysfunction with an EF of 15%-20% with preserved right ventricular function.
