Inverted left atrial appendage mimicking a left atrial mass after surgical repair of an atrial septal defect: a case report.

Background: Inverted left atrial appendage (ILAA) is a rare condition following cardiac surgery. Failure to recognize the condition or making misdiagnosis of a tumour, a thrombus or vegetation can lead to unnecessary and potentially adverse events. We present a case of ILAA after surgical repair of an atrial septal defect (ASD) in a young female.

Cost-effectiveness of transcatheter versus surgical aortic valve replacement in patients at lower surgical risk: results from the NOTION trial.

Aims: The aim of this study was to estimate the cost-effectiveness of transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR) in patients at lower surgical risk.

Methods And Results: Discounted costs from a societal perspective and effectiveness as quality-adjusted life years (QALYs) were projected to lifetime via a decision-analytic model calibrated to 60-month data from the NOTION trial. The base case assumed a scenario in which any mortality benefit would gradually fade out over time, with other scenarios explored in sensitivity analyses.
