Tako-Tsubo cardiomyopathy after radiofrequency ablation of atrioventricular nodal reentrant tachycardia

Tako-Tsubo cardiomyopathy following colonoscopy: Insights on pathogenesis

“…Similarly, Derntl et al reported two cases of post radiofrequency ablation TTC following posterior atrial wall ablation and evidence of vagal withdrawal concurrent with the stress of the procedure [12]. Latcha et al reported a case of TTC after posteroseptal slow pathway ablation also site of known vagal innervation once again occurring along with the stress of the procedure [13]. Artukoglu et al reported a patient who developed TTC after orthoscopic knee surgery [21].…”

“…Excessive sympathetic discharge has been thought to be a primary pathogenic factor possibly through induced microvascular changes [11]. Prior reports have documented a plethora of potential triggers for TTC and have included surgery, radiofrequency ablation [12,13] and even upper gastrointestinal contrast radiography [14]. The occurrence of post procedural TTC has not been reconciled with present thoughts on the pathogenesis of this syndrome.…”
