Two female patients undergoing left atrial radiofrequency catheter ablation developed Tako‐tsubo cardiomyopathy. This reversible form of left ventricular dysfunction is known to occur under conditions associated with marked sympathetic nervous activation. Radiofrequency catheter ablation in the left atrium can damage autonomic ganglionated plexi, leading to vagal withdrawal, thus resulting in enhanced sympathetic tone. Tako‐tsubo cardiomyopathy has not been previously described following radiofrequency catheter ablation.
