In takotsubo cardiomyopathy, the clinical appearance is that of an acute myocardial infarction in the absence of obstructive coronary artery disease, with apical ballooning of the left ventricle. The condition is usually precipitated by a stressful physical or psychological experience. The mechanism is unknown but is thought to be related to catecholamine excess. We present the case of a 67-year-old woman who experienced cardiogenic shock caused by takotsubo cardiomyopathy, immediately after undergoing elective direct-current cardio-version for atrial fibrillation. After a course complicated by left ventricular failure, cardiogenic shock, and ventricular tachycardia, she made a complete clinical and echocardiographic recovery. In addition to this case, we discuss the possible direct effect of cardioversion in takotsubo cardiomyopathy.

<p>Stress cardiomyopathy (SCM), also called broken heart syndrome and Takotsubo cardiomyopathy is an increasingly reported syndrome generally characterized by transient systolic dysfunction of the apical and or mid segments of the left ventricle that mimics myocardial infarction, in the absence of obstructive coronary artery disease. Typically patients present within a few hours of exposure to physical or emotional stress. However, the mechanism by which these stressors result in myocardial dysfunction is unclear. Proposed factors include catecholamine excess and coronary vasospasm<sup>1</sup>. We present the case of a 61-year-old female who experienced acute pulmonary edema secondary to stress cardiomyopathy, on two occasions immediately after undergoing elective direct current cardioversion (DCCV) for atrial fibrillation (Afib). After an urgent hospitalization for management of acute left ventricular failure, she made a complete clinical and echocardiographic recovery.  The incidence, clinical implications and prognosis of DCCV induced SCM is unknown. Given DCCV for Afib is a common outpatient procedure and DCCV induced SCM can lead to acute clinical deterioration it is important that physicians are vigilant about this newly recognized electrical cardioversion complication.</p>

Takotsubo cardiomyopathy, or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction caused by transient wall-motion abnormalities of the left ventricular apex and mid ventricle in the absence of obstructive coronary artery disease. Recurrent episodes are rare but have been reported, and several cases of takotsubo cardiomyopathy have been described in the presence of hyperthyroidism. We report the case of a 55-year-old woman who had recurrent takotsubo cardiomyopathy, documented by repeat coronary angiography and evaluations of left ventricular function, in the presence of recurrent hyperthyroidism related to Graves disease. After both episodes, the patient's left ventricular function returned to normal when her thyroid function normalized. These findings suggest a possible role of thyroid-hormone excess in the pathophysiology of some patients who have takotsubo cardiomyopathy.

Recurrent Atrial Fibrillation

Objective. Direct-current electrical cardioversion is the main method for the conversion of atrial fibrillation. Its success depends on many factors. In several studies, biphasic shock waveforms have been demonstrated to be superior to monophasic shocks for termination of atrial fibrillation; however, information about impact of paddle position is controversial. Initial energy level is an object of discussions. The aim of the study was to compare a truncated exponential biphasic waveform with monophasic damped sine waveform and antero-lateral with antero-posterior paddle positions for cardioversion of atrial fibrillation, to determine its impact on early reinitiation of atrial fibrillation. Material and methods. A total of 224 consecutive patients with atrial fibrillation underwent electrical cardioversion with biphasic (Bi, n=112) or monophasic (Mo, n=112) shock waveform in a randomized fashion. The position of hand-held paddle electrodes was randomly selected in both groups to be anterior-lateral and anterior-posterior. Energies used were 100–150–200–300–360 J (Bi) or 100–200–300–360 J (Mo). If monophasic shock of 360 J was ineffective, we used biphasic shock of 360 J. Early recurrent atrial fibrillation (ERAF) was defined as a relapse of atrial fibrillation within 2 min after a successful cardioversion, acute recurrent – within 24 h. Results. Two study groups (Bi vs Mo) did not differ with regard to age, body mass index, duration of AF episode (mean 98±147 days for the Bi group and 80±93 days for the Mo group, P=0.26), underlying heart disease, left atrial diameter, left ventricular ejection fraction. In the Mo group, more patients used amiodarone (59.82% vs 41.97%, P=0.002), in the Bi group more patients used propafenone (16.07% vs 8.93%, P=0.033). Cardioversion success rate was 97.32% in the Bi group and 79.46% in the Mo group (P<0.001). After biphasic shock of 360 J in Mo group, the cumulative success rate was 99.11%. Mean delivered energy and mean number of shocks were significantly lower in the Bi group (198.5±204.4 J, 1.5±0.9 shocks vs 489.1±464.2 J, 2.4±1.5 shocks). The efficacy of first shock was 66.96% in the Bi group and 37.5% in the Mo group (P<0.0001). Incidence of ERAF was 4.46% in both groups. Paddle position had no impact on efficacy of cardioversion and ERAF. Conclusions. For the cardioversion of atrial fibrillation, biphasic shock waveform has a higher success rate than monophasic shock waveform. We did not observe the influence of paddle positions on efficacy of cardioversion. Shock waveform and paddle position had no impact on ERAF. We recommend starting with biphasic energy of 150 J and monophasic of not less than 200 J for cardioversion of atrial fibrillation.

Background: Takotsubo Cardiomyopathy (TTC) is an uncommon cause of acute reversible ventricular systolic dysfunction in the absence of obstructive Coronary Artery Disease (CAD). Typically manifesting as apical wall ballooning, TTC can rarely present atypically with apical wall sparing. Case report: A 62-year-old female presented with complaints of chest pain and features mimicking acute coronary syndrome. Coronary angiogram revealed no obstructive CAD and left ventriculogram showed reduced ejection fraction, normal left ventricular apex and hypokinetic mid-ventricles consistent with atypical TTC. The patient was discharged home on heart failure medications and a follow-up transthoracic echocardiogram demonstrated improved left ventricular function with no wall motion abnormality. Conclusion: This case report provides an insight into the diagnosis and management of TTC in the absence of pathognomic features.

Abstract Background A ‘catecholamine storm’ in a case of pheochromocytoma can lead to a transient left ventricular dysfunction similar to Takotsubo cardiomyopathy. A cardiogenic shock can thus develop, with high left ventricular end-diastolic pressure and a reduction in coronary perfusion pressure. This scenario can ultimately lead to a cardiac arrest, in which unloading the left ventricle with a peripheral left ventricular assist device (Impella®) could help in achieving the return of spontaneous circulation (ROSC). Case summary A patient affected by Takotsubo cardiomyopathy caused by a pheochromocytoma presented with cardiogenic shock that finally evolved into refractory cardiac arrest. Cardiopulmonary resuscitation was performed but ROSC was achieved only after Impella® placement. Discussion In the clinical scenario of Takotsubo cardiomyopathy due to pheochromocytoma, when cardiogenic shock develops treatment is difficult because exogenous catecholamines, required to maintain organ perfusion, could exacerbate hypertension and deteriorate the cardiomyopathy. Moreover, as the coronary perfusion pressure is critically reduced, refractory cardiac arrest could develop. Although veno-arterial extra-corporeal membrane oxygenation (va-ECMO) has been advocated as the treatment of choice for in-hospital refractory cardiac arrest, in the presence of left ventricular overload a device like Impella®, which carries fewer complications as compared to ECMO, could be effective in obtaining the ROSC by unloading the left ventricle.

Apical ballooning syndrome (ABS) is an under recognised clinical entity characterised by acute reversible left ventricular systolic dysfunction that mimics acute myocardial infarction in the absence of obstructive coronary artery disease; typically occurring in the setting of profound stress.1 ABS disproportionately affects older women and recurrences are infrequent. We, hereby, describe a rare phenomenon of recurrent ABS in an elderly male patient, 10 years apart, presenting with the same left ventricular morphological appearance following non-cardiac surgeries. The case illustrates the importance of considering ABS in the differential diagnosis of perioperative acute myocardial infarction in older men undergoing major surgery.
