Abstract
Primary cardiac tumors are relatively rare, and myxoma, the most common variety, is found predominantly in the left atrium. Clinical presentation varies from asymptomatic incidental masses to serious life-threatening cardiovascular complications. Some cases are difficult to diagnose, as symptoms can be nonspecific. We present a case of a young female with 4 months of history of dyspnea, weight loss, and night sweats, eventually diagnosed as a case of large left atrial myxoma arising from the anterior mitral valve through transthoracic echocardiography.
