Key result
Left atrial appendage intussusception follows cardiac procedures in ~80% of cases, mostly resolving without open surgery.
Why the study?
Cardiac mass assessment is challenging in the intraoperative scenario, and the left atrial appendage can be a rare cause of an acute left atrial mass.
Systematic Review (n=25)
Recognize LAA inversion intraoperatively to avoid misdiagnosis; Level 5 data leave incidence and management strategies open.
Cardiac mass assessment is challenging in the intraoperative scenario. We present the case of a 22-year-old woman with a new-onset left atrial mass during cardiopulmonary bypass following closure of a ventricular septal defect. We discuss the role of intraoperative echocardiographic examination, the differential diagnosis, and raise awareness of the left atrial appendage as a rare etiology of an acute left atrial mass.
