• BackgroundThe prevalence and evolution of Takotsubo cardiomyopathy (TCM) post-catheter ablation in atrial fibrillation (AF) patients is unknown.ObjectiveWe present 5 reported cases of TCM in patients receiving AF ablation at our center.MethodsPatients developing symptoms of TCM following AF ablation were included in this review. The syndrome was diagnosed based on the clinical presentation and cardiac imaging, i.e. echocardiography and LV angiogram. Besides, coronary angiography was performed to exclude arterial stenosis.ResultsFive cases of TCM (3 females) were reported of the 11,500 AF ablations performed at our center to date. In 3 cases, the syndrome was diagnosed 1-2 days post-ablation whereas in the other two, it manifested much later following severe emotional stress. Thus, TCM complicating AF ablation was seen in 3 of 11,500 patients (0.026%), which demonstrate the rarity of this complication. None had evidence of coronary artery stenosis. Most common presenting symptoms were respiratory distress and chest pain. Reduction in LVEF (19±4.2%) and the typical apical LV ballooning was detected in all (figure). Four patients recovered completely, without any treatment in 3 and with conservative therapy for heart failure in one. The 5 patient with malignant presentation was treated conservatively but died on the 3 day of the diagnosis after multiple episodes of electromechanical dissociation.ConclusionTakotsubo syndrome is uncommon following AF ablation and mostly resolves without intervention. Very rarely a malignant presentation is seen for which the best treatment approach is still unclear. FigureLV angiogram in diastole (left) and systole (right)
