Excision of a left atrial myxoma with mitral and tricuspid valve repair.

A left atrial myxoma is the most common benign tumor of the heart, but it is still uncommon, with a reported prevalence of 0.03% in the general population. In developing countries, patients may present late with a stroke or with pulmonary artery hypertension and ventricular dysfunction. We may need to address the mitral and tricuspid valves in such cases. This video tutorial illustrates the technical aspects of myxoma excision along with modified De Vega tricuspid annuloplasty. The mitral valve was structurally normal and free from tumor; therefore, it was not touched in the first place but had to be repaired because there was severe regurgitation after the tumor was excised. The presence of left ventricular dysfunction can indicate a dilated mitral annulus and the need to repair the mitral valve.
