Myxomas make up roughly half of all primary cardiac tumors, with three-quarters originating in the left atrial cavity and one-quarter in the right. These tumors can occur sporadically or in families. Atrial myxomas are classified as severe based on factors such as their size, the patient's age and gender, and the tumor's proclivity to embolize or occlude coronary vessels. The case of a young female with an unusual presentation of left atrial myxoma and a new neurovascular deficit is discussed.
