Leiomyosarcoma with coronary fistulae and ventricular septal perforation: A case study

Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of any abnormal cardiac mass. Therefore, the malignant cardiac tumors could appear in an invasive form without mass and be one of the causes of the coronary fistulae and ventricular septal perforation.
