Abstract
- BACKGROUND
Cardiac myxoma is uncommon, even though accounts for 50% of primary cardiac tumor, histologically benign disease but may be lethal because of its strategic position. It has diverse clinical manifestations mimicking various diseases, which can be described under the three headings: constitutional, obstructive and embolic and the diagnosis can be easily missed unless clinician has high index of suspicion. A correct diagnosis is made before operation with the development of echocardiography. We reviewed our clinical experience in diagnosis and management of 21 cases of myxomas from 1985 to 2000.
METHODS
There were 4 males (19%) and 17 females (81%). Their ages ranged from 17 to 66 years (mean 42.2 years). All the patient's medical records on their clinical features, laboratory findings, chest X-rays, electrocardiograms, echocardiographic findings, operative findings and postoperative follow-up were reviewed.
RESULTS
Seventeen cases (81%) of the myxomas originated in left atrium and four (19%) in right atrium. Most common symptom was that of intracardiac obstruction such as dyspnea or dyspnea on exertion (62%). Fatigue which accounted for most of the constitutional symptom found in 38% of the 21 patients while embolism accounted for 38%. In all patients, echocardiography was used for diagnosis and the diagnostic accuracy of echocardiography was 100%. All patients received surgical treatment and immediate postoperative complications occurred in seven patients (33%). Among them, serious complications were found in two cases and one expired due to congestive heart failure. Follow-up duration ranged from 2 months to 15 years. There was no recurrence or other problem in all patients during the follow-up period.
CONCLUSION
Although clinical suspicion is difficult due to the nonspecific presentation of myxoma, the diagnosis can be made easily with echocardiographic examination in all cases and surgical excision of myxoma may be curative with good long-term result.
