Why the study?
What is the incidence of incomplete surgical left atrial appendage ligation during mitral valve surgery?
Population
50 patients who underwent mitral valve surgery and ligation of the left atrial appendage (LAA)
Design
Cohort
Follow-up
immediately postoperative to 13 years after surgery
Key result
Surgical left atrial appendage ligation during mitral valve surgery was found to be incomplete in 36% (18 of 50) of patients assessed by transesophageal echocardiography.

May warrant caution assuming surgical LAA closure success without imaging; leaves open optimal techniques and surveillance in mitral valve surgery.
Observational (n=50)
What is the incidence of incomplete surgical left atrial appendage ligation during mitral valve surgery?
Surgical LAA ligation during mitral valve surgery is frequently incomplete (36%), which may create a milieu for stagnant blood flow and potential embolic events.
Katz et al. (2000) conducted an observational in Mitral valve surgery and ligation of the left atrial appendage (n=50). Surgical left atrial appendage ligation was evaluated on Incidence of incomplete ligation of the left atrial appendage. Surgical left atrial appendage ligation during mitral valve surgery was found to be incomplete in 36% (18 of 50) of patients assessed by transesophageal echocardiography.
