a b s t r a c tWe report on a 64-year-old female patient who underwent cardiac surgery for left atrial myxoma, using the superior septal approach with large atrial septal wall resection and patch closure. The superior septal approach is reported to be a relatively safe method for preventing the development of sinus node dysfunction after cardiac surgery. However, this patient developed sinus node dysfunction after surgery and required the implantation of a permanent pacemaker. Moreover, in this case, determining the appropriate positions of the pacemaker leads was difficult because of the presence of a large conduction delay in the interatrium. Selecting the appropriate atrioventricular delay settings was important in order to achieve proper sequential contractions between the left atrium and the left ventricle.

“…The superior septal approach (SSA) is one of the surgical approaches used for myxoma resection. Cases that require pacemaker implantation after SSA have been reported to be very rare [4,5]. We herein describe the case of a patient who required pacemaker implantation after surgery with the SSA for the treatment of a left atrial myxoma.…”

“…In such cases, patch repair are required to close the defect, and many methods have been reported. 8) Because the defect was very large in our case, two patches were used for individual reconstruction of the right and left atrium. We found that this reconstruction method was very effective, and we suggest that it may be useful in cases of atrial myxoma for which extensive resection is necessary.…”

The efficacy and safety of surgical intervention for atrial myxoma are established, but the operative approach to tumor resection and atrial reconstruction are controversial. A biatrial approach is generally used for excision of atrial myxoma and has many advantages. In contrast, there are a few reports about the method of double-patch reconstruction, and the right and left atrium are individually reconstructed with the two patches. We found it to be effective in the case reported here. We suggest that this method can be applied to atrial myxoma in which extensive resection is necessary.

“…It is characterized by the presence of myxoid matrix, rich in acid mucopolysaccharides that are produced by a number of spindle-shaped cells [2]. Myxomas were observed in different locations, including the maxillary sinuses in two horses [3], the diaphragmatic lobe of the right lung in a sheep [4], and the interatrial septum of the heart of an older (72-year-old) man [5].…”
