Takotsubo cardiomyopathy – an unexpected complication in spine surgery

Hammer, Niels, Kühne, Christian, Meixensberger, Jürgen, Hänsel, Bernd, Winkler, Dirk 16 December 2014 (has links) (PDF)
Introduction: Takotsubo cardiomyopathy is an apical ballooning syndrome, which can be triggeredby stress. Only few case reports describe the onset of Takotsubo as a complication of neurosurgery procedures. Clinical presentation: A case of a 53 year-old female with a spinal neurinoma and surgery-associated Takotsubo cardiomyopathy is demonstrated. The patient developed typical signs of a myocardial infarction with circulation depression and ST elevation, but normal cardiac enzymes at the end of surgery. Cardiac catheterization and levocardiography confirmed the absence of any critical coronary disease but the presence of a typical apical ballooning and midventricular hypokinesis. The patient recovered completely under supportive conservative and cardiological therapy, showing regular left ventricular pumpfunction. Conclusion: Interventions in neurosurgery and perioperative care should be kept as stress free as possible. Due to the possibility of neurogenic mechanisms related to cardiomyopathy, Takotsubo cardiomyopathy as an entity of stress-induced complications should be taken into consideration.

Takotsubo Cardiomyopathy Mimicking Stent Thrombosis After Percutaneous Coronary Intervention

Khattak, Furqan, Khalid, Muhammad, Murtaza, Ghulam, Paul, Timir K. 30 April 2018 (has links)
Takotsubo cardiomyopathy, also known as “broken heart syndrome,” is a transient left ventricular dysfunction associated with stress (usually emotional) induced myocardial injury and stunning. It often presents as myocardial infarction on surface electrocardiogram (EKG). Diagnosis is made by coronary angiography, which rules out coronary artery disease and shows pathognomonic apical ballooning. In this article, we present a case of a 72-year-old woman who initially presented with an ST segment elevation myocardial infarction on EKG. Coronary angiography showed severe left anterior descending artery and diagonal lesions requiring percutaneous coronary intervention. Post–percutaneous coronary intervention, EKG changes resolved. The next day, the patient developed recurrent chest pain and her EKG showed diffuse T-wave inversion in precordial leads with reemerging ST segment elevations concerning for stent thrombosis. The patient underwent repeat emergent coronary angiography, which showed patent stents and findings consistent with takotsubo cardiomyopathy.

Tako-Tsubo Syndrome as a Consequence of Transient Ischemic Attack

Abi-Saleh, Bernard, Iskandar, Said B., Schoondyke, Jeffrey W., Fahrig, Stephen 01 December 2006 (has links) (PDF)
An 82-year-old woman presented to the emergency department with chest pain after sustaining a transient ischemic attack 1 week prior to presentation. Electrocardiography revealed ST-segment elevation in leads I, II, aVF, and V3 through V6. Coronary angiography demonstrated nearly normal coronaries but left ventriculography showed apical akinesis and basal hyperkinesis. One month later her follow-up echocardiography showed no wall motion abnormalities. Several reports of tako-tsubo syndrome or transient left ventricular apical ballooning have been described, especially in Japan. We present a case with the typical features of the syndrome after a cerebrovascular accident.
