    Abstract:
    At the University Department of Cardiovascular Surgery in Zagreb, Croatia, we treated 81 patients with primary intracardiac myxoma, in a period from January 1975 to December 1994. There were 55 female and 26 male pts, in age from 1 month to 80 years, mean 46+/-15 years. Clinical manifestations varied from no symptoms and very poor or no clinical signs to various manifestations of chronic or acute congestive heart failure, syncope and arrhythmias with or without systemic findings such as high erythrocyte sedimentation rate, anaemia, leucocytosis, elevated gamma globulin, thrombocytopenia or low grade fever, as well as cerebrovascular accidents due to tumour embolization. Cardiac symptoms were predominant in 54 pts (66.6%) and cerebrovascular in 20 pts (24.7%). Seven pts (8.6%) were symptomless and discovered accidentally, mostly regarding on an unexplained heart murmur. In almost all the patients preoperative diagnosis of intracardiac myxoma was sufficiently established by echocardiography. The tumour was located in the left atrium in 62 pts (76.5%) and in the right atrium in 19 pts (23.5%). Delay from the onset of symptoms to the diagnosis was 6 months in average (range 10 days to 25 months). The average waiting for the operation was 9 days (range from 1 to 60 days). The echocardiographic diagnosis was confirmed during intraoperative examination followed by histological analysis. All pts underwent excision of myxoma using cardiopulmonary bypass with core and topical hypothermia and cold crystaloid cardioplegia. According to the additional preoperative and intraoperative findings, in 6 pts sinchronous mitral valve reconstruction, in 3 pts artificial mitral valve implantation and in 2 pts atrial wall reconstruction was performed. There was no perioperative mortality. After the operation, we could not evaluate all the patients long enough, mostly because of some paramedical circumstancies, such as war, migrations, etc. Twenty two pts undevent evaluation for at least 5 years after the operation. Among them there was no evidence of the tumour recurrence, 15 pts were asymptomatic and 7 had NYHA II class symptoms. For 17 pts with a left atrial myxoma preoperative and postoperative echocardiographic data were available for comparison, showing a significant reduction of the left atrial diameter (p<0.001) during the postoperative follow-up. Our data, presenting one of the biggest reports concerning cardiac myxomas, showed a broad spectrum of their clinical presentation, importance of echocardiography in diagnosing and postoperative follow-up and efficacy of a proper surgical intervention as a definite, curative therapy since there were no deaths and no significant cardiac dysfunction neither tumour reccurrence as well.
