Abstract:
Objective To study the clinical manifestations of cardiac myxoma and the morbidity, mortality and recurrence rate following surgery in our institution. Methods From December 1989 to November 2004, 71 patients underwent complete excision of primary or recurrent intracardiac myxoma. Pre-operative diagnosis was established by echo-cardiography. All patients underwent operation soon after the diagnosis of myxoma was made. Combined cardiac disorder was also treated synchronously. The excised myxoma was histopathologically studied routinely. Results Myxoma most commonly occurred in the fourth decade of life. Its commonest location (92.9%) was the left atrium (LA), but 3 patients had myxoma in the right atrium (RA), one in the right ventricle (RV), and one in the left ventricle (LV). Patients with LA myxoma simulated mitral stenosis clinically, whereas patients with RA and RV myxoma presented features of right heart failure. Patients with LV myxoma had the symptoms of the left ventricular outlet tract obstruction. 6 patients had history of embolism. Combined cardiac diseases included coronary heart disease (2 cases), rheumatic mitral stenosis (2 cases), and severe mitral insufficiency (3 cases), and severe tricuspid insufficiency (4 cases). One patient had myxoma recurrence for three times after his first surgery, and died in the fourth operation. All the other patients survived the operation with the condition improved during the follow-up period. No late deaths were observed. Conclusions Echocardiography is the ideal diagnostic tool. Immediate surgical treatment is indicated in all patients. Cardiac myxoma can be excised with a low rate of mortality and morbidity. Close follow-up for detecting recurrence is necessary.
