BACKGROUND: This single-center study reviews our experience with cardiac myxomas over the past decade. METHODS: Sixty-two patients (23 male) with median age 38 years (range: 8 to 69 years) underwent excision of primary or recurrent cardiac myxomas between 2000 and 2009. Patients were evaluated with echocardiography preoperatively and annually postoperatively. Follow-up is current for all survivors (range 13 months to 10 years). RESULTS: Fifty-two patients had left atrial myxomas, seven right atrial, two biatrial, and one right ventricular. Three cases were familial. Maximum number of myxomas in a single patient was four. Symptom duration ranged from two to eight months. Two early deaths were due to low cardiac output and embolic cerebrovascular accident; one late death was due to a noncardiac cause. Actuarial survival was 96.8 ± 1.8% at 10 years. Most patients were asymptomatic following surgery. No sporadic, multiple, or biatrial myxomas recurred. Recurrence occurred in two familial cases, both with single, left atrial myxoma. Freedom from reoperation was 98.4 ± 1.3% at five years and 96.8 ± 1.8% at 10 years. CONCLUSIONS: Biatrial involvement or multiplicity of myxomas does not mandate recurrence. Surgical excision has excellent overall survival and freedom from reoperation rates, but annual follow-up including echocardiographic surveillance is recommended as familial cases tend to recur.
