Abstract
Abstract Introduction Perioperative Takotsubo cardiomyopathy (pTC) represents a rare and still not well characterized disease. Biventricular involvement is an uncommon manifestation of TC and is associated with a more severe clinical presentation. Case report A 72-year-old male, hospitalized for a laparoscopic left hemicolectomy, was transferred to ICU after having developed severe bradycardia, treated with Adrenalin, and cardiogenic shock during induction of general anesthesia. EKG showed complete atrio-ventricular block, so a temporary PMK was placed. Troponin was raised. Echocardiogram showed severe biventricular disfunction (LVEF 25%, TAPSE 12 mm) with akinesia of medio-apical segments, suggesting a biventricular pTC. Also, there was a reduction of 3D LV longitudinal strain (- 5,8%), particularly of the medio-apical portion, and RV free wall longitudinal strain (- 11%). Coronary angiography resulted negative. Patient's hemodynamic was supported with Noradrenalin and a cycle of Levosimendan, allowing to reach stability. Further echocardiogram showed improvement of biventricular function and longitudinal strain values. Due to the persistency of atrio-ventricular block, a definitive PMK was placed. Patient was discharged after therapy optimization. Discussion pTC is a little-known disease, as incidence and etiology are not well definite. Literature suggests a relation between pTC and physical or emotional stress due to surgery to promote an increase of catecholamine release. Other potential factors may be inadequate depth of anesthesia or tracheal manipulation during intubation and catecholaminergic drugs administration. On the other hand, the use of anesthetic volatile agents seems to have a cardioprotective effect. PTC is more common during general anesthesia and when occurs intraoperatively has a worse clinical presentation. Biventricular involvement, which is a rare and severe manifestation of TC, has been reported frequently among pTC patients. To date, due to the lack of a systematic review, there is little knowledge about potential risk factors, prevention strategies and management of pTC. Conclusions Despite multiple cases of pTC have been reported, several characteristics of this entity are not fully understood. However, it must be considered as a part of differential diagnosis in patients with anaesthesia-related decompensation. Biventricular involvement represents an infrequent presentation and its commonly associated with life-threating hemodynamic impairment.
