Review Case Reports
Mitral valve myxoma: a case report and brief review of the literature.
A case of cardiac myxoma arising from the mitral valve is reported. A 50-year-old woman presented with history of shortness of breath and angina. ⋯ At surgery, the tumor was found to be arising from the anterior leaflet of the mitral valve. The tumor was excised and a defect in the anterior leaflet of the mitral valve was repaired by direct suture.

Although the results of intracardiac repair for pulmonary stenosis or atresia are generally good, some patients develop symptoms due to to pulmonary regurgitation and right ventricular dilatation. Implantation of a pulmonary homograft may have a beneficial effect on these symptoms. Twenty-seven patients with symptoms due to pulmonary regurgitation and right ventricular dilatation were reoperated. ⋯ We conclude that pulmonary regurgitation after transannular patching can be treated with implantation of a cryopreserved pulmonary homograft with acceptable mortality and low morbidity. Clinical improvement results from reduction of the right ventricular volume overload rather than from decline in right ventricular dilatation. Arrhythmia as the only indication for operation is controversial.
