A surgical operation on a patient with infected left atrial myxoma is presented. The patient was a 50-year-old woman who was admitted to the Kyung Hee Medical Center Hospital on March 7 1987 with complaints of high fever, cough and dyspnea that occurred a few days prior to admission. She, who no definite history of the previous cardiac-related problems was obtained from, had visited a dentist to have her eight teeth pulled out a few months prior to this admission. A preoperative 2-D echocardiogram revealed a left atrial tumor, strongly suggesting myxoma and two blood cultures drawn prior to surgery yielded streptococcus viridans. Under the preoperative impression of an infected left atrial myxoma, the tumor was removed through a biatrial approach after establishing CPB and cold cardioplegic. Pathologic examination of the tumor demonstrated a typical myxoma with bacterial colonies within. Postoperative course was uneventful and she was completely well at discharge from the hospital. To our best knowledge, this report is the first surgical experience of infected left atrial myxoma in the Korean literature.

Myxoma constitue about 50% of a II primary cardiac, tumor (incidence 0.03%) and occur in any of the cardiac chambers, but about 75% of themare found in the left atrium. As is well known, left atrial myxoma usually simulates mitral valvular disease, and it tends to bring about postural syncope and frequent embolic manifestaticns. The clinical manifestation of left atrial myxoma upon the circulation are obstructive effects, embolic effects and constitutional effects. Diagnosis is now most of all important since surgery can be dramatically curable, whereas untreated myxoma apparently invariably lead to deadful course. Preaprative diagncsis by echocardiogram is so simple and accurate for detection of myxoma that awareness of mitral valvular heart disease with rapid deterioration must be screened. We have diagnosed one case of the left atrial myxoma preopratively by phonocardiogram, echocardiogram and levophase pulmonary angiograJ;n and successfully treated by operation under extra corporeal circulation. A 38 years old housewife was admitted to the National Medical Center because of dyspnea, and paroxysmal cough on occasions for prior to hospitalization. Operation was carried out by median sternotomy and left atriotomy with mild hypothermia under E.C.C. The left atrial myxoma was extirpated including endocardial fragment and its weight was 23gm. The hospital course was not eventful and she can work nowadays without symptoms.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.

Primary cardiac tumors usually are benign and are left atrial myxoma. We experienced with two cases of left atrial myxoma recently, and underwent surgical resection successfully. Diagnoses were obtained by echocardiogram and the angiocardiography was not performed. The operation consisted of excision of the tumor with a segment of atrial septum or wall through a right atriotomy, transseptal approach. Postoperative functional results were good and the literature is reviewed.

A 33-year-old man presented to the physician with epigastric discomfort. Computed tomography of the chest and echocardiography showed a mass in the left atrium; this mass was resected and diagnosed as myxoma. 12 months later, myxoma recurred in the right atrium, and it was resected without recurrence for 10 months until now. As there are only a few reports on recurred right atrial myxoma after left atrial myxoma, we report here on successful surgical removal of a recurred right atrial myxoma after resection of left atrial myxoma.

Systemic emboli occur in approximately one-third of patients with cardiac myxoma. Embolization is common because of the friability of the tumor and intracardiac location. Embolic episodes in young patients with normal sinus rhythm should arouse suspicions of cardiac myxoma in the absence of active endocarditis. We present one case of 17 years old girl having saddle embolism combined with left atrial myxoma. We planned staged operation. First, the emergency thromboembolectomy of aortic bifurcation was performed through bilateral transfemoral approach with use of Forgaty catheter. One week later, the extirpation of myxoma was successfully done with ECC.

Cardiac myxoma is most significant benign tumors constituting nearly 50% of all primary cardiac tumors. Its diagnosis is important because prognosis is excellent by surgical therapy and is usually fatal if unrecognized and untreated. Recently the development of diagnostic procedure and cardiac surgery increased the accuracy of diagnosis and the opportunity of successful treatment. Two cases of left atrial myxoma removed successfully were presented.

Left atrial myxoma constitutes the most significant cardiac tumors, which occupies 30 to 50% of the total in most pathological series with the age range from 3 to 83 years, mostly between the age of 30 to 60 years. Over 90% of myxomas occur in the atria, with 3 to 4 times as many occurring in the left as in the right. They may cause severe and progressive disease mimicking mitral valvular disease with non-specific general symptoms. Recent attentions were focussed in the clinical features along with various diagnostic techniques including angiocardiography, echocardiography and cross-sectional sector scanning echocardiography, and definitive treatment with surgical removal under direct vision using cardiopulmonary bypass. There are several reports on the atrial myxomas removed from various cardiac chambers in Korea, and we report another typical case of left atrial myxoma of 6.8 x 3.8 x 1.7 cm3 attached to the upper margin of fossa ovalis with a short pedicle, also with calcification at it`s distal free end. 29 year old young mother complaining of mild fever, vaginal spotting, numbness of left upper and lower extremities, nocturnal attack of dyspnea and palpitation for 2 months was diagnosed as large left atrial myxoma with the aid of angiocardiography and echocardiography. Trans-right-atrial, transseptal surgical removal of the tumor was successfully performed under the cardiopulmonary bypass for 22 minutes on 24th of July 1980. Postoperative hospital course was uneventful and discharged from hospital on the 12th POD with complete recover from the previous symptoms and signs.

Left atrial myxoma, an unusual clinical entity, may cause severe and progressive cardiac disease mimicking mitral valvular disease. In recent years, increased clinical awareness and improved diagnostic techniques has led to a higher incidence of correct preoperative diagnosis. Recently we experienced 2 cases of left atrial myxoma, which were removed successfully under the cardiopulmonary by pass. The first case was 45 years old woman and the second was 23 years old female. Preoperative definite diagnosis was entertained by angiocardiography and echocardiography in both cases. In the first case, tumor was removed with left atriotomy and atrial septectomy was done with additional right atriotomy. In the second case, tumor and atrial septum were removed en bloc through the right atrium. Both patients were discharged with good results 2 weeks postoperatively.

Seven patients [six cases of left atrial myxoma, one case of right atrial myxoma] from 24 to 66 years of age [4 male and 3 female, mean age 48 years] underwent excision of atrial myxoma between 1982 and 1989 at Keimyung University Dongsan Medical Center. All patients presented with congestive heart failure, six with cardiac murmur, three with syncope, two with sinus tachycardia, one each with sinus arrhythmia, atrial fibrillation, pleural effusion, peripheral embolization. Symptoms were present from 1 month to 8 years before operation [mean 28 months], All tumors originated from atrial septum and pedunculated. The myxomas were successfully removed in all patients, either shaving them from atrial septum [n=3] or by excising a portion at normal atrial septum with tumor [n=4]. One case was replaced mitral valve with carbomedics-31mm due to severe mitral regurgitation. Follow up is current. No recurrent myxoma has been identified clinically or by echocardiography. In this series, excellent results were obtained by simple excision of the tumor, with or without a margin of normal atrial septum.
