Takotsubo (Stress) Cardiomyopathy and the Anesthesiologist: Enough Case Reports. Let's Try to Answer Some Specific Questions!

Severe stress cardiomyopathy following spinal corrective surgery for scoliosis complicated with pectus excavatum: a case report

BACKGROUND

Stress cardiomyopathy (SCM) is an acute heart failure syndrome characterized by transient, usually reversible left ventricular systolic dysfunction with normal or enhanced basal compensatory wall motion abnormalities involving the left ventricular anterior septum and apex, resulting in a "ballooning" appearance. However, it has rarely been reported in patients undergoing spinal surgery.

CASE PRESENTATION

We report a case of severe stress cardiomyopathy in a scoliosis patient with pectus excavatum who underwent spinal corrective surgery. During the wake-up period, circulatory collapse occurred. After multidisciplinary consultation, the patient was diagnosed with stress cardiomyopathy. At last, she had a good prognosis after a series of treatments including ECMO.

CONCLUSION

Stress cardiomyopathy is a reversible but uncommon condition. It can cause death if it is not diagnosed in time. Consequently, this report should improve the awareness of orthopedists and anesthesiologists for timely identification and management. For patients with potential risk factors, timely preoperative intervention should be performed to reduce the occurrence of stress cardiomyopathy.

Longitudinal Strain Patterns in Stress (Takotsubo) Cardiomyopathy: Evidence of Global Myocardial Injury and Incomplete Recovery

Stress cardiomyopathy develops after abrupt sympathetic stimulation, likely from catecholamine-induced myocardial toxicity. The evolution of myocardial strain during and after an episode have not been previously characterized. We aimed to determine whether preexisting contractile abnormalities may explain the observed regional dysfunction during an acute episode and to investigate the persistence of strain abnormalities after clinical recovery. We identified patients who were diagnosed with stress cardiomyopathy and had an echocardiogram performed before their episode, during their episode, and within 1 year after. The diagnosis was confirmed based on the absence of obstructive coronary lesions. Left ventricular (LV) longitudinal strain was calculated using speckle-tracking software and compared between baseline, episode, and follow-up echocardiograms. The LV strain analysis was performed on 23 patients. The LV ejection fraction was 64 ± 8.7% at baseline, 45 ± 12% during the episode, and 5 9 ± 10% after a median follow-up of 46 days. The LV global longitudinal strain was 24 ± 4.7% at baseline, 11 ± 4.9% during the episode, and 19 ± 4.6% after the follow-up. The mean ejection fraction (p <0.01) and global longitudinal strain (p <0.001) remained below baseline levels at follow-up. Longitudinal strain was reduced (<18%) in 80 ± 23% of myocardial segments during an episode and 41 ± 21% of myocardial segments at follow-up. During the acute episode, 35 ± 6% of the abnormal segments were in the base, outside of the region of ballooning. Our findings suggests that stress cardiomyopathy is associated with global rather than regional myocardial injury and that contractile abnormalities persist after clinical improvement. These findings challenge our previous understanding of stress cardiomyopathy and may guide future pathophysiologic understanding of this complex disease.

The Safety and Strategies for Reinitiating Electroconvulsive Therapy After ECT-Induced Takotsubo Cardiomyopathy: A Case Report and Systematic Review

OBJECTIVES

Takotsubo cardiomyopathy (TCM) is a life-threatening complication of electroconvulsive therapy (ECT). We report the case of a 66-year-old woman who was rechallenged with ECT after ECT-induced TCM. Moreover, we have made a systematic review to assess the safety of and strategies for reinitiating ECT after TCM.

METHODS

We searched for published reports on ECT-induced TCM since 1990 in MEDLINE (PubMed), Scopus, Cochrane Library, ICHUSHI, and CiNii Research.

RESULTS

A total of 24 ECT-induced TCM cases were identified. Patients who developed ECT-induced TCM were predominantly middle-aged and older women. There was no specific trend in anesthetic agents used. Seventeen (70.8%) cases developed TCM by the third session in the acute ECT course. Eight (33.3%) cases developed ECT-induced TCM despite the use of β-blockers. Ten (41.7%) cases developed cardiogenic shock or abnormal vital signs related to cardiogenic shock. All cases recovered from TCM. Eight (33.3%) cases tried to receive ECT retrial. The duration until ECT retrial was between 3 weeks and 9 months. The most common preventive measures during ECT retrial were related to β-blockers; however, the type, dose, and route of administration of β-blockers varied. In all cases, ECT could be reperformed without TCM recurrence.

CONCLUSIONS

Electroconvulsive therapy-induced TCM is more likely to cause cardiogenic shock than nonperioperative cases; nevertheless, it has good prognosis. Cautious reinitiation of ECT after TCM recovery is possible. Further studies are required to determine preventive measures for ECT-induced TCM.

A study of takotsubo syndrome over 9 years at the Tokyo Cardiovascular Care Unit Network Registry

BACKGROUND

Takotsubo syndrome (TTS) is an acute cardiovascular disease with clinical manifestations similar to those of acute myocardial infarction (AMI), and TTS sometimes occurs just after catastrophes. Large-scale studies of TTS in Japan are scarce, so we examined data over 9 years from Tokyo metropolitan acute cardiovascular care hospital network registry.

METHODS

A total of 1626 patients were diagnosed with TTS between 2010 and 2018 at Tokyo Cardiovascular Care Unit Network facilities, and data from all these patients were analyzed. We investigated annual and monthly captured incidence of TTS, temporal trend of the captured incidence proportion of TTS versus AMI, the occurrence of TTS on the day of the great earthquake, and we elucidated the prognostic factors for in-hospital death.

RESULTS

The annual incidence proportion of TTS versus AMI increased from 2.3 % to 4.5 % (p < 0.001) over 9 years. The mean TTS patient age was 74.4 years: the peak incidence of TTS was at 80 to 84 years of age for both male and female; females accounted for 78.5 % of patients. The monthly variation of the incidence of TTS was found (p = 0.009). In 2011, a total of 137 cases of TTS occurred, with as many as 6 occurring on March 11, the day of the Great East Japan Earthquake. There was a definable trigger for TTS in 64 % (physical: 36 %; emotional: 27 %; others: 2 %). All-cause in-hospital mortality was 5.3 % and was higher in males than in females (10.3 % vs 3.9 %; p < 0.001). Non-cardiac causes accounted for 62 % of in-hospital mortality. Factors at presentation that were associated with in-hospital all-cause mortality were male sex, low body mass index, and a high C-reactive protein level.

CONCLUSIONS

This study elucidated the clinical features, in-hospital outcomes, and their attributed factors in patients with TTS in real-world clinical practice in Japan.

A simple procedure in a complex patient: perioperative takotsubo cardiomyopathy

Takotsubo cardiomyopathy (TTC) is a rare but life-threatening condition that is still not completely understood. Characterised by rapidly reversible ventricular dysfunction without any prior coronary artery disease, it can imitate a myocardial infarction and lead to death if not managed appropriately. This report examines a case of intraoperative cardiac arrest in a patient with no previous cardiac disease, and discusses the factors that may have precipitated this event, as well as the ways of distinguishing the cause of the arrest based on clinical course and investigations, eventually leading to a diagnosis of TTC.

Variants of Takotsubo syndrome in the perioperative period: A review of potential mechanisms and anaesthetic implications

Takotsubo syndrome (TS) is a condition of transient cardiac dysfunction that develops in the setting of abrupt sympathetic stimulation. Although classically identified by ballooning of the apical segment, TS can also present in atypical forms with abnormalities of the basal, mid-ventricular, or other focal segments. In the perioperative setting, anaesthetic effects and physiologic perturbations from surgery can further confound the diagnosis. We present a narrative review of the most recent evidence for underlying pathophysiologic mechanisms of the variable ballooning patterns and highlight important anaesthetic considerations in the diagnosis and management of these patients.

Head Rules Over the Heart: Cardiac Manifestations of Cerebral Disorders

The Brain-Heart interaction is becoming increasingly important as the underlying pathophysiological mechanisms become better understood. "Neurocardiology" is a new field which explores the pathophysiological interplay of the brain and cardiovascular systems. Brain-heart cross-talk presents as a result of direct stimulation of some areas of the brain, leading to a sympathetic or parasympathetic response or it may present as a result of a neuroendocrine response attributing to a clinical picture of a sympathetic storm. It manifests as cardiac rhythm disturbances, hemodynamic perturbations and in the worst scenarios as cardiac failure and death. Brain-Heart interaction (BHI) is most commonly encountered in traumatic brain injury and subarachnoid hemorrhage presenting as dramatic electrocardiographic changes, neurogenic stunned myocardium or even as ventricular fibrillation. A well-known example of BHI is the panic disorders and emotional stress resulting in Tako-tsubo syndrome giving rise to supraventricular and ventricular tachycardias and transient left ventricular dysfunction. In this review article, we will discuss cardiovascular changes caused due to the disorders of specific brain regions such as the insular cortex, brainstem, prefrontal cortex, hippocampus and the hypothalamus; neuro-cardiac reflexes namely the Cushing's reflex, the Trigemino-cardiac reflex and the Vagal reflex; and other pathological states such as neurogenic stunned myocardium /Takotsubo cardiomyopathy. There is a growing interest among intensivists and anesthesiologists in brain heart interactions as there are an increasing number of cases being reported and there is a need to address unanswered questions, such as the incidence of these interactions, the multifactorial pathogenesis, individual susceptibility, the role of medications, and optimal management.

KEY MESSAGES

BHI contribute in a significant way to the morbidity and mortality of neurological conditions such as traumatic brain injury, subarachnoid hemorrhage, cerebral infarction and status epilepticus. Constant vigilance and a high index of suspicion have to be exercised by clinicians to avoid misdiagnosis or delayed recognition. The entire clinical team involved in patient care should be aware of brain heart interaction to recognize these potentially life-threatening scenarios.

A Case of Takotsubo Cardiomyopathy After Local Anesthetic and Epinephrine Infiltration

Takotsubo cardiomyopathy (TC) is a non-ischemic cardiomyopathy that is accompanied by sudden left ventricular myocardial stunning, dilation and dysfunction. It often results from severe emotional or physical stress. We present the case of a 41-year-old female patient who had general anesthesia induced uneventfully for an elective bladder sling procedure. After an intravaginal injection of local anesthesia (lidocaine 2%; epinephrine 1:100,000) just prior to the surgical incision, the patient had cardiovascular collapse for which cardiopulmonary resuscitation (CPR) was performed. The patient was eventually stabilized but transesophageal echocardiography showed impairment in cardiac motion and remarkably reduced ejection fraction. Troponin levels were elevated but coronary angiography was unremarkable. The ejection fraction returned to normal the next day. Local anesthetic with epinephrine administration can lead to TC, and with optimal management, long-term cardiac sequela can be avoided.

Takotsubo Cardiomyopathy after Spinal Anesthesia for a Minimally Invasive Urologic Procedure

We present the case of a patient who suffered from Takotsubo cardiomyopathy (TCM) immediately after the initiation of subarachnoid anesthesia for a minimally invasive urologic procedure (tension-free vaginal tape (TVT) surgery for stress urine incontinence). TCM mimics acute coronary syndrome and is caused by an exaggerated sympathetic reaction to significant emotional or physical stress. Our patient suffered from chest pain, palpitations, dyspnea, and hemodynamic instability immediately following subarachnoid anesthesia and later in the postanesthesia care unit. Blood troponin was elevated and new electrocardiographic changes appeared indicative of cardiac ischemia. Cardiac ultrasound indicated left ventricular apical akinesia and ballooning with severely affected contractility. The patient was admitted to coronary intensive care for the proper care and finally was discharged. TCM was attributed to high emotional preoperative stress for which no premedication had been administered to the patient. In conclusion, adequate premedication and anxiety management are not only a measure to alleviate psychological stress of surgical patients, but, more importantly, an imperative mean to suppress sympathetic nerve system response and its cardiovascular consequences.

Perioperative Takotsubo Cardiomyopathy: A Systematic Review of Published Cases

Takotsubo cardiomyopathy (TCM) is a condition that is characterized as a transient ventricular dysfunction in the absence of obstructive coronary artery disease (CAD) and is usually triggered by an acute medical illness or intense physical or emotional stress. Multiple cases of perioperative TCM (pTCM) have been reported from around the world, but a qualitative analysis of these cases has not yet been done. For this systematic review, we searched PubMed for case reports and case series of pTCM published from 1966 to April 2015 with the objective being to evaluate whether differences in demographics, clinical features and outcomes exist between pTCM and nonperioperative (npTCM), as well as to attempt to identify any predictors of the severe form of pTCM, which requires mechanical circulatory support (MCS) devices or leads to death. A total of 93 articles describing 102 cases were retrieved and reviewed. The findings were compared with the analysis of the International Takotsubo Registry by Templin et al and a systematic review of mainly non-perioperative TCM (npTCM) by Gianni et al. Although we were unable to identify definitive risk factors for pTCM, our review suggests that pTCM appears to occur in younger patients and with a lower likelihood of ST segment elevations and T-wave abnormalities than in npTCM. No demographic or clinical factors were identified that were predictive of more severe outcomes. As TCM in general can be a life-threatening event, it would therefore be prudent to consider pTCM within a differential diagnosis in any patient who decompensates in the perioperative period.

Subsequent Safe Pregnancy with Cesarean Delivery in a Patient with a History of Peripartum Takotsubo Syndrome Complicated by Cardiogenic Shock

Takotsubo syndrome (TTS) is an acute and reversible heart failure syndrome, usually occurring in females but rarely in the peripartum period. In women with a history of peripartum TTS, it is unclear how to manage subsequent pregnancies. A 39-year-old female with a history of peripartum TTS complicated by cardiogenic shock became pregnant again. She underwent close cardiological follow-up for monitoring left ventricular systolic function and hemodynamic conditions. Epidural anesthesia was preferred to avoid catecholamine surge during cesarean delivery. After a few days of hospitalization, the patient and the newborn were discharged in good health. In our patient with a history of complicated peripartum TTS, close cardiological follow-up, appropriate management therapy, and anesthesia modality allow us to guide safely a new pregnancy.

Cardiomyopathies and anaesthesia

Cardiomyopathy is considered as a heart muscle disease of multiple aetiologies, unlike other cardiac diseases related to a definitive pathophysiology. With more and more research and with the advent of genetic analysis pin pointing the disease causing mutations, causative factors have been defined and classifications and definitions have changed over time. Patients with these conditions present to anaesthesiologists in elective and emergency situations, placement of automated internal cardioverter defibrillator (AICD) devices or biventricular pacing but may also be diagnosed at anaesthetic pre-assessment. We describe cardiomyopathies such as dilated cardiomyopathy, hypertrophic cardiomyopathy, post-partum cardiomyopathy and Takotsubo cardiomyopathy in brief and their anaesthetic management.

[Perioperative approach of patient with takotsubo syndrome]

INTRODUCTION

Takotsubo cardiomyopathy (TCM) is a stress-induced cardiomyopathy. It is characterized by an acute onset of symptoms and electrocardiographic abnormalities mimicking an acute coronary syndrome in the absence of obstructive coronary artery disease. Any anesthetic-surgical event corresponds to a stressful situation, so the anesthetic management of patients with TCM requires special care throughout the perioperative period. We describe the anesthetic management of a patient with a confirmed diagnosis of TCM undergoing segmental colectomy.

CASE REPORT

Female patient, 55 years old, ASA III, with history of takotsubo syndrome diagnosed 2 years ago, scheduled for segmental colectomy. The patient, without other changes in preoperative evaluation, underwent general anesthesia associated with lumbar epidural and remained hemodynamically stable during the 2hours of surgery. After a brief stay in the Post-Anesthesia Care Unit, she was transferred to the Intermediate Care Unit (IMCU), with epidural analgesia for postoperative period.

CONCLUSION

TCM is a rare disease which true pathophysiology remains unclear, as well as the most appropriate anesthetic-surgical strategy. In this case, through a preventive approach, with close monitoring and the lowest possible stimulus, all the perioperative period was uneventful. Because it is a rare disease, this report could help to raise awareness about TCM.

Case report of Tako-Tsubo cardiomyopathy associated with repetitive anaesthesia in a female patient with Tako-Tsubo cardiomyopathy

Background

Tako-Tsubo cardiomyopathy (TTC) is a rare disorder with high relevance for anaesthesia. It is an acute cardiac syndrome characterized by an acute onset of reversible left ventricular dysfunction associated with emotional and physical stress. This is the only case published of a patient having five severe Tako-Tsubo incidents in five consecutive general anaesthesia procedures within one year.

Case presentation

A 61 years old female patient (height 1.65 m; weight 70 kg) presented with a haemorrhagic pituitary adenoma with compression of the optic chiasm and was scheduled for transnasal endoscopic tumour resection. We report a case series with five consecutive anaesthesia procedures in the same patient for neurosurgery.

This case series is remarkable since the severe symptoms occurred during every anaesthesia procedure. The female patient was resuscitated two times including therapeutic hypothermia, but fortunately no neurological or cognitive deficit was detectable.

Conclusions

TTC may initially present in the perioperative period with pulmonary oedema, electrocardiographic (ECG) changes, elevation of cardiac enzymes, and cardiogenic shock or cardiac arrest.

Since the risk of recurrence is considered to be low in TTC, this case report is of high interest. In each procedure similar clinical signs were found which resulted in severe haemodynamic derangements in every manifestation and cardiac arrest in two of the manifestations. Despite cardiopulmonary resuscitation twice, the patient survived without any neurological deficiency.

Brain-heart crosstalk: the many faces of stress-related cardiomyopathy syndromes in anaesthesia and intensive care

Neurogenic stress cardiomyopathy (NSC) is a well-known syndrome complicating the early phase after an acute brain injury, potentially affecting outcomes. This article is a review of recent data on the putative role of localization and lateralization of brain lesions in NSC, cardiac innervation abnormalities, and new polymorphisms and other genetic causes of the sympathetic nervous system over-activity. Concerns regarding the management of stress-related cardiomyopathy syndromes during the perioperative period are also discussed. Future clinical research should explore whether specific factors explain different patient susceptibilities to the disease and should be directed towards early identification and stratification of patients at risk, so that such patients can be more carefully monitored and appropriately managed in critical care and during the perioperative period.

Unusual perioperative cardiac emergency in a healthy young woman

Serious cardiac complications occurring during noncardiac surgery in a young and otherwise normal person can be quite alarming for the anesthesiologist. We report here the case of a young, healthy woman who immediately after an uncomplicated spinal surgery developed a clinical picture suggestive of an acute myocardial infarction (MI) with positive relevant investigations. However, she had an abrupt and full clinical recovery and complete normalization of her cardiac investigations within a few days of this event and thereafter continued to lead a normal, symptom-free life unlike the usual course in an MI; her coronary angiography was also normal. A diagnosis of perioperative stress-induced cardiomyopathy or Takotsubo cardiomyopathy was subsequently made. This condition is characterized by a rapid, severe, but reversible, cardiac dysfunction triggered by physical or mental stress. Awareness of this entity should help anesthesiologists manage better this infrequent, but potentially life-threatening, perioperative complication.
