Case Report: Takotsubo Syndrome Induced by Severe Anaphylactic Reaction During Anesthesia Induction and Subsequent High-Dose Epinephrine Resuscitation

A rare case report of catecholamine-induced takotsubo in a patient with anaphylaxis shock due to amoxicillin-clavulanate

Takotsubo syndrome (TTS), also known as stress cardiomyopathy, is a life-threatening condition characterized by transient left ventricular dysfunction with nonischemic abnormalities. This syndrome in scenarios of anaphylactic shock is quite rare, with only a few cases reported. Early diagnosis and treatment are crucial. We presented a rare case of 58-year-old woman presented to our hospital due to an anaphylactic shock. The patient was stable and in the de-escalation dose of adrenaline (0.05 µg/kg/h). Twenty-two hours from exposure, the patient experienced pulmonary edema that required intubation, both adrenaline and dobutamine to maintain blood pressure. Echocardiography revealed a reduced ejection fraction of 35%. Subsequent coronary angiography showed no signs of coronary obstruction and left ventriculography provided typical apical ballooning and hyperkinesia in the basal region, highly suggesting TTS. The patient was successfully treated with inotrope and vasopressor and was discharged in stable condition after 7 days and improved normal heart function after 4 weeks. This case demonstrates the delayed onset of adrenaline-induced takotsubo complicated with pulmonary edema in a patient with anaphylactic shock due to antibiotics despite a de-escalation dose of adrenaline. Regardless of the duration of the event or the optimal epinephrine dosage in patients with anaphylactic shock, physicians should be aware of the risk of TTS.

Cardiac stress in a child with perioperative anaphylaxis

A case of cardiac stress following a grade 4 perioperative anaphylaxis was identified. We speculate that this may be a case of Kounis or adrenaline, takotsubo, anaphylaxis and Kounis (ATAK) complex. This is the first such case reported from the UK. We propose performing routine cardiac investigations in patients with grade 4 anaphylaxis or chest pain following anaphylaxis to evaluate any similar future presentations.

Mechanical Circulatory Support Strategies in Takotsubo Syndrome with Cardiogenic Shock: A Systematic Review

BACKGROUND

Takotsubo syndrome is, by definition, a reversible form of acute heart failure. If cardiac output is severely reduced, Takotsubo syndrome can cause cardiogenic shock, and mechanical circulatory support can serve as a bridge to recovery. To date, there are no recommendations on when to use mechanical circulatory support and on which device is particularly effective in this context. Our aim was to determine the best treatment strategy.

METHODS

A systematic literature research and analysis of individual patient data was performed in MEDLINE/PubMed according to PRISMA guidelines. Our research considered original works published until 31 July 2023.

RESULTS

A total of 93 publications that met the inclusion criteria were identified, providing individual data from 124 patients. Of these, 62 (50%) were treated with veno-arterial extracorporeal life support (va-ECLS), and 44 (35.5%) received a microaxial left ventricular assist device (Impella). Eighteen patients received an Impella CP and twenty-one an Impella 2.5. An intra-aortic balloon pump (IABP) without other devices was used in only 13 patients (10.5%), while other devices (BiVAD or Tandem Heart) were used in 5 patients (4%). The median initial left ventricular ejection fraction was 20%, with no difference between the four device groups except for the IABP group, which was less affected by cardiac output failure (p = 0.015). The overall survival was 86.3%. Compared to the other groups, the time to cardiac recovery was shorter with Impella (p < 0.001).

CONCLUSIONS

Though the Impella treatment is new, our analysis may show a significant benefit of Impella compared to other MCS strategies for cardiogenic shock in Takotsubo syndrome.

Not all Shock States Are Created Equal: A Review of the Diagnosis and Management of Septic, Hypovolemic, Cardiogenic, Obstructive, and Distributive Shock

Shock in the critically ill patient is common and associated with poor outcomes. Categories include distributive, hypovolemic, obstructive, and cardiogenic, of which distributive (and usually septic distributive) shock is by far the most common. Clinical history, physical examination, and hemodynamic assessments & monitoring help differentiate these states. Specific management necessitates interventions to correct the triggering etiology as well as ongoing resuscitation to maintain physiologic milieu. One shock state may convert to another and may have an undifferentiated presentation; therefore, continual re-assessment is essential. This review provides guidance for intensivists for management of all shock states based on available scientific evidence.
