Injury of the sinus node in open-heart operations

Single-patch, 2-patch, and caval division techniques for repair of partial anomalous pulmonary venous connections: Does it matter?

“…Sinus node dysfunction can occur with incisions involving the SVC or close to the cavoatrial junction. 13 Junctional rhythm was identified in 4 after single-patch repair in the series by Iyer and colleagues, 7 with no other rhythm abnormalities with the 2-patch technique. Rhythm abnormalities were observed in only 2 patients among the 18 patients who underwent cavoatrial incisions in the series by DeLeon and colleagues.…”

Comparative study of single- and double-patch techniques for sinus venosus atrial septal defect with partial anomalous pulmonary venous connection

“…There are reports that an incision in the SVC or across the cavoatrial junction may cause sinus node dysfunction in follow-up even if there is no injury to the node or the artery because of fibrosis in that area. 15 We have not encountered such events in longterm follow-up. DeLeon and colleagues 16 observed rhythm abnormalities in only 2 of the 18 patients with cavoatrial incisions through the sinus node.…”

Successful surgical repair in an older adult with supracardiac total anomalous pulmonary venous connection: A case report

“…The single-patch technique uses only one patch to drain pulmonary vein blood from the SVC to the LA. Rhythm disturbance and SVC obstruction are known procedural complications due to an inadequate blood supply to the sinus node during surgery ( 17 ). Schuster and colleagues used an extra patch (two-patch technique) to broadening the SVC–RA junction to achieve an unobstructed SVC drainage and, thus, reproducible without an increase in complications, such as pulmonary venous obstruction or SVC stenosis or any rhythmic issues ( 18 ).…”
