Prolonged circulatory support with an Impella assist device in the management of cardiogenic shock associated with takotsubo syndrome, severe sepsis and acute respiratory distress syndrome

Favorable Effects of Impella on Takotsubo Syndrome Complicated with Cardiogenic Shock

Reportedly, approximately 9.9%-12.4% of patients with Takotsubo syndrome (TTS) are complicated with cardiogenic shock (CS) and its prognosis remains poor even with the support of conventional mechanical circulatory assist devices including intra-aortic balloon pumping and venoarterial extracorporeal membrane oxygenation. Impella, a novel percutaneous left ventricular assist device, provides strong circulatory support together with the unloading of the left ventricle, and it is theoretically a promising mechanical circulatory assist device for TTS. In this case study, we report four consecutive patients with TTS complicated with CS who were successfully resuscitated using the Impella support.

Prolonged Use of an Impella Assist Device in a Sepsis-Induced Cardiomyopathy: A Case Report

The inflammatory response triggered by sepsis can frequently cause reversible myocardial depression termed sepsis-induced cardiomyopathy. The resulting pathologic changes are often self-limiting and cardiac function returns to baseline following resolution of the underlying exacerbating factors. The following case examines a patient with septic shock and sepsis-induced cardiomyopathy that, despite maximal medical therapy, required mechanical support with an Impella assist device for seven days. To the best of our knowledge and research, this represents the longest documented use of an Impella heart pump in septic shock and associated sepsis-induced cardiomyopathy. Utilization of mechanical support in the setting of septic shock has seen growing interest in recent years, but more structured studies need to be conducted for better understanding of their overall effect on morbidity and mortality.

Systemic inflammation in patients with Takotsubo syndrome: a review of mechanistic and clinical implications

Over recent decades, systemic inflammation  as  quantified  with  inflammation  markers  or  indices has been extensively  investigated  in the setting of  various  cardiovascular  conditions  including heart failure (HF),  acute coronary syndromes (ACS). In contrast, systemic inflammation  in patients with  takotsubo syndrome (TTS) has been an underrated  phenomenon in clinical practice. On the other hand, experimental and clinical data  have been  rapidly  accumulating  in the recent years  regarding   pathogenetic, prognostic as well as therapeutic implications of  systemic inflammation in TTS.  Accordingly, the present article  aims to provide a general perspective  on mechanistic and  clinical aspects of  systemic  inflammation in the setting of  TTS.
