Perioperative management of Takotsubo cardiomyopathy: an overview.

Resembling the morphology of Japanese polyp vessels, the classic form of Takotsubo cardiomyopathy is characterized by the presence of systolic dysfunction of the mid-apical portion of the left ventricle associated with basal hyperkinesia. It is believed that this may be due to a higher density of β-adrenergic receptors in the context of the apical myocardium, which could explain the greater sensitivity of the apex to fluctuations in catecholamine levels.The syndrome is precipitated by significant emotional stress or acute severe pathologies, and it is increasingly diagnosed during the perioperative period.

Introduction And Importance: Takotsubo syndrome (TTS) is a reversible form of acute heart failure often triggered by physical or emotional stressors. Minimally invasive mitral valve surgery (MIMVS) has become a prevalent approach for treating mitral valve pathologies, yet its association with TTS remains underexplored.
Case Presentation: We present the case of a female patient undergoing MIMVS with concomitant Maze ablation, who developed TTS postoperatively.

Background: Differentiating Takotsubo cardiomyopathy (TTC) from acute coronary syndrome involving the left anterior descending coronary artery (LAD-ACS) is difficult due to left ventricular apical wall motion abnormality pattern in both and typically requires an invasive coronary angiography (ICA) study for diagnostic confirmation.
Objectives: To identify differences in the regional wall motion abnormality (RWMA) pattern using a comprehensive comparative analysis of the transthoracic echocardiographic (TTE) findings in patients with TTC versus LAD-ACS.
Methods: This was a retrospective, randomized, blinded comparison study including a derivation cohort of 105 patients with TTC (N=52) or LAD-ACS (N=53) with concomitant TTE and ICA identified from our institutional database.
Myasthenic Crisis and Concomitant Takotsubo Syndrome Complicated by Shock.
Intern Med
December 2024
Department of Cardiology, Tokyo Metropolitan Tama Medical Center, Japan.
A man in his 80s with myasthenia gravis (MG) developed dysmobility and chest discomfort. An electrocardiogram revealed ST-segment elevation, and coronary angiography revealed Takotsubo syndrome (TTS). He experienced myasthenic crisis that required ventilation and shock that was refractory to vasopressors and required intra-aortic balloon pump (IABP) insertion.

Since the first description of takotsubo syndrome 30 years ago, only a little is known on the underlying physiopathology leading to peculiar left ventricular function alteration and myocardial damage related to acute emotional or physical stress. In the present case, we used continuous invasive thermodilution to evaluate coronary microvascular function at the acute phase of takotsubo and after recovery. The acute phase of takotsubo was characterized by a reduced coronary output and altered reserved flow with persistently high resistance during hyperaemia.
