Key result
Repeated radiofrequency ablations for atrial fibrillation can cause stiff left atrial syndrome, presenting with recurrent dyspnea and elevated left atrial pressure without mitral regurgitation.
Case Report (n=1)
Stiff left atrial syndrome should be considered in patients presenting with recurrent dyspnea and elevated left atrial pressure after multiple radiofrequency ablations for atrial fibrillation.
Stiff left atrial syndrome warrants consideration in post-ablation dyspnea with elevated LA pressure; this case report leaves open questions on incidence and prevention.
We present the case of a patient who underwent repeated ablations for atrial fibrillation and presented with recurrent dyspnea, elevated left atrial pressure with large V waves in the absence of mitral regurgitation. This case provides an example of "stiff left atrial syndrome" as has been described in patients with mitral valve replacement and only recently in patients with radiofrequency ablations for atrial fibrillation.

Witt et al. (2012) conducted a case report in Atrial fibrillation (n=1). Radiofrequency ablation was evaluated. Repeated radiofrequency ablations for atrial fibrillation can cause stiff left atrial syndrome, presenting with recurrent dyspnea and elevated left atrial pressure without mitral regurgitation.
