LONG-TERM FOLLOW-UP OF CARDIAC MYXOMAS (7-31 YEARS)

Between 1961 and 1985, 14 patients (9 males, 5 females; mean age 42.3 +/- 7.26 years) underwent surgery for excision of cardiac myxoma. Origin of the neoplasm was left atrium in all patients. In the last 7 cases diagnosis was obtained by echocardiographic examination. The clinical manifestations were dyspnea in 8 cases, palpitation in 5 and neurological symptoms in 3. One patient with concomitant mitral and aortic incompetence died on the 13th postoperative day because of low-output syndrome. All 13 operative survivors are alive and well without echocardiographic evidence of neoplastic recurrence at a follow-up ranging from 7 to 31 years. These results indicate a low incidence of recurrence with a complete tumor excision even without its extension to the normal atrial endocardium.
