ABSTRACT
Background:
Cardiac myxoma is the most common primary cardiac tumor.Aim:
To evaluate clinical aspects, diagnostic methods and surgical outcomes in patients with cardiac myxoma. Patients andMethods:
AH patients who underwent surgical resection of a cardiac myxoma between January 1973 and December 2004 at our institution, were identified and their medical records and diagnostic data reviewed.Results:
Thirty seven patients identified (24 women), with a median age of 54 years (range 2-74). The most common symptom was dyspnea (51 percent), followed by embolism (24 percent) and cardiac murmurs (16 percent). The diagnosis was made by echocardiogram in 84 percent of patients. The mean tumor size was 4.9 ± 1.3 cm. The tumor was located in the ¡eft atrium in 83 percent of the patients, right atrium in 8 percent and ¡eft ventricle in 3 percent. Two patients had multiple tumors. Surgical approach was transeptal in 51 percent, left atriotomy in 22 percent, combined transeptal and roof of the left atrium in 19 percent and right atriotomy in 8 percent. The tumor and its attachment base were excised in one piece. There were two operative deaths and five late deaths. The mean follow-up was 11.5 years. The 5, 10, 15 and 20 years survival was 89 percent, 83 percent, 75 percent and 64 percent, respectively. Two patients had recurrence (5.4 percent), at 2 and 25years after surgery, respectively, and the recurrence free survival at 10 and 25years was 97 percent and 73 percent, respectively.Conclusions:
Dyspnea was the most common symptom and echocardiogram the main diagnostic method. Surgical treatment was highly effective, with low mortality and recurrence rate, with good long term survival.
