Key result
Diligent hemodynamic assessment differentiates stiff left atrial syndrome from overlapping cardiac conditions.
Why the study?
Stiff left atrial syndrome is a complication of left atrial scarring following procedures such as catheter ablation, but its clinical manifestations can overlap with other conditions.
Case Report (n=4)
This case series highlights the diagnostic challenges of stiff left atrial syndrome and the necessity of diligent hemodynamic assessment to differentiate it from overlapping cardiac conditions.
Background: Stiff left atrial syndrome (SLAS) is a complication that occurs due to left atrial scarring following procedures such as radiofrequency catheter ablation for atrial fibrillation. Case summary: We present a series of four patients with pre-existing conditions that ultimately were diagnosed as SLAS. In each case, clinical manifestations of SLAS may overlapped with other conditions and required a high index of clinical suspicion and diligent hemodynamic assessment to differentiate it from other concomitant cardiac conditions. Discussion: We aim to highlight key differentiating diagnostic features from overlapping cardiac conditions and to summarize current treatment options for patients with SLAS.

Banthiya et al. (2025) conducted a case report in Stiff left atrial syndrome (SLAS) (n=4). A case series of 4 patients with stiff left atrial syndrome demonstrates that diligent hemodynamic assessment is required to differentiate it from overlapping cardiac conditions.
