ABSTRACT
Background: A 56-year-old male with a past history of excision of a malignant melanoma from his lip presented with squeezing chest pain. The patient was evaluated and determined to have a tumor of the left ventricle. Excision of such a tumor is indicated to prevent embolization and also to prevent the possibility of outflow tract obstruction.
Methods: The patient underwent transesophageal echocardiography and was placed on cardiopulmonary bypass with cold-blood cardioplegia. The ascending aorta was opened and a video-assisted cardioscope was inserted through the aortic valve and used to visualize the tumor. The tumor was resected under direct vision and the aorta was closed.
Results: Frozen section analysis revealed the tumor to be a benign hemangioma. The patient had an uneventful recovery with no evidence of ventricular septal defect or embolization.
Conclusions: Performing the cardioscopy via the aortotomy helped us to avoid an atriotomy and/or ventriculotomy and enabled us to discern the precise extent of the tumor and rule out concomitant pathology. The use of cardioscopy as an adjunct for excision of intraventricular abnormalities can assist in determining the precise location and size of tumors and in resecting tumors in areas of the heart that might otherwise be difficult to visualize.
