The distinction between cardiac aneurysms and diverticula can be very difficult by angiography. Left ventricular (LV) aneurysms usually occur following transmural myocardial infarction. On the other hand, cardiac diverticula are most commonly congenital. They are commonly detected by cardiac CT with a prevalence of 2.2%. Here we present a case of a 60-year-old male with the incidental finding of multiple LV aneurysms masquerading as diverticula in the setting of myocardial infarction with near normal coronary arteries. Moreover, this case highlights the limitation of coronary angiography in the diagnosis of myocardial infarction with no obstructive atherosclerosis (MINOCA).

Objective: We present the case of possible reverse type of TCM in a female patient presented with progressive left ventricular dysfunction and its rupture in pericardium. Methods: The detailed history, physical examination, laboratory tests, electrocardiography, serial echocardiography, coronary angiography with left ventriculography were performed to diagnose possible Takotsubo cardiomyopathy in 63-year old woman admitted to our center with complaints of dyspnea, lightheadedness, weakness and signs of hypotension and history of inferior myocardial infarction, acute left ventricular aneurysm, and effusive pericarditis and pleuritis, developed after emotional stress 5 months ago. Results: Clinical evaluation revealed unremarkable laboratory tests, normal troponin values, signs of old inferior myocardial infarction on electrocardiogram, and left ventricular (LV) dilatation and dysfunction, akinesia of LV infero-lateral wall with thinning and its rupture and blood shunting in pericardium. Her coronary angiography revealed normal coronary arteries. The diagnosis of pheochromocytoma was excluded. The patient underwent surgery under cardiopulmonary bypass with removal of LV pseudoaneurysm. The patient was discharged from hospital with improvement in NYHA class and LV function. Conclusion: Thus, in female postmenopausal patients presenting with acute myocardial infarction signs complicated by pericarditis, intact coronary arteries and LV dysfunction with emotional stress as triggering factor, reverse type of TCM should be considered and proper management applied to prevent development of life-threatening complications like LV rupture.

Normal Coronary Arteries

Myocardial infarction with normal coronary arteries is a syndrome resulting from numerous conditions but the exact cause in a majority of the patients remains unknown. Cigarette smokers and cocaine users are more prone to develop this condition. The possible mechanisms causing myocardial infarction with normal coronary arteries are hypercoagulable states, coronary embolism, an imbalance between oxygen demand and supply, intense sympathetic stimulation, non-atherosclerotic coronary diseases, coronary trauma, coronary vasospasm, coronary thrombosis, and endothelial dysfunction. It primarily affects younger individuals, and the clinical presentation is similar to that of myocardial infarction with coronary atherosclerosis. Thrombolytics, aspirin, nitrates, and beta blockers should be instituted as a standard therapy for acute myocardial infarction. Once normal coronary arteries are identified on subsequent angiography, the calcium channel blockers could be added since coronary vasospasm appears to play a major role in the pathophysiology of this condition. The beta blockers should be avoided in cocaine-induced myocardial infarction because the coronary spasm may worsen. In myocardial infarction with normal coronary arteries, complications such as malignant arrhythmia, heart failure, and hypotension are generally less common, and prognosis is usually good. Recurrent infarction, postinfarction angina, heart failure, and sudden cardiac death are rare. Stress electrocardiography and imaging studies are not useful prognostic tests and long- term survival mainly depends on the residual left ventricular function, which is usually good.

Background and Aims: It is well known that ST segment elevation myocardial infarction results from complete occlusion of a coronary artery supplying that area. However, in up to 15% of patients with clinical diagnosis of myocardial infarction, early angiography reveal either non-obstructive or normal coronary artery. This subgroup of disease, myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA), represent a diagnostic and therapeutic challenge to clinicians. We aimed to determine prevalence and clinical profile of patients with MINOCA in current study. Methods: This is a retrospective, observational study conducted in cardiology department of Manipal Teaching Hospital, Pokhara, Nepal from 6th April 2014 to 5th April 2019. Patients with age ≥18 years and clinically diagnosed acute myocardial infarction who underwent coronary angiography without prior use of thrombolytic agents were selected. Data were analyzed using the software SPSS for windows version 18. Results: A total of 177 patients’ underwent early coronary angiography without prior use of thrombolytic agent. The prevalence of MINOCA was 13.5% (n=24) in our study population. MINOCA patients were younger (p<0.001) compared to non-MINOCA. Smoking, systemic hypertension, access through femoral route and depressed left ventricular ejection fraction were significantly lower in MINOCA patients (p<0.05, for all). Conclusion: The prevalence of MINOCA was high (13.5%) in our study. Prospective studies are needed to conclude its high prevalence and to look for other associated factors and etiology.

Abstract Background Patients with suspected ST-elevation myocardial infarction (STEMI) and normal coronary arteries comprise a heterogeneous group with various underlying causes of disease. Purpose To study pathophysiology and underlying diagnoses in patients with suspected STEMI and normal coronary arteries using multimodal cardiac imaging. Methods We consecutively included patients with suspected STEMI, normal coronary arteries on acute coronary angiography, and elevated troponin T levels at a tertiary heart center (2012–14). Patients were examined with echocardiography, cardiac magnetic resonance imaging, and 13NH3/82Rb and 18F-FDG positron emission tomography within one week from symptom onset. Results We included 42 patients (60% male, median age 58 (IQR 50–65) years. Median troponin T levels were 783 (IQR 566–1208) ng/l. Multimodal cardiac imaging findings are presented in Table 1. Multimodal cardiac imaging showed signs of cardiac involvement in all but one patient (98%). Underlying diagnoses were acute myocardial infarction (36%), Takotsubo cardiomyopathy (29%), perimyocarditis (10%), and cardiomyopathy (7%). The diagnosis was unclear in 19% of patients.

Annotation. In Ukraine, one of the most pressing medical and social problems is coronary heart disease, in particular, such a form as myocardial infarction. Also, as in most countries, coronary heart disease plays a leading role in morbidity and mortality. In Ukraine, coronary heart disease accounts for 65% of the mortality from diseases of the circulatory system of the working population and is the main cause of disability. The aim of the work is to determine the features of the structural and functional state of the myocardium in patients with myocardial infarction without ST segment elevation depending on the nature of the anatomical lesion of the coronary arteries. We conducted a comprehensive study of 200 patients with acute myocardial infarction without ST-segment elevation (NSTEMI) aged 38 to 80 years. According to coronary angiography, the degree of damage to the coronary arteries was determined, and according to echocardiography – the structural and functional state of the myocardium. Comparison of percentages between groups was performed by the criterion χ2, absolute values – by Mann-Whitney U test. The structural condition of the left ventricular myocardium in NSTEMI patients deteriorated significantly. The total severity of coronary artery disease, calculated from coronary angiography, was> 3, indicating a more severe anatomical lesion of the coronary arteries in these patients. This pathology was associated primarily with an increase in the incidence of eccentric left ventricular hypertrophy. A similar association has been established with regard to the development of left ventricular diastolic dysfunction.

Abstract Aims Tachycardiomyopathy (TCM) is a reversible cause of left ventricular dysfunction, secondary to rapid and/or asynchronous, irregular myocardial contraction. The disease can be divided in two main subgroups: arrhythmia-induced TCM also known as pure TCM, where the arrhythmia is the sole reason for the dysfunction, and impure TCM also known as arrhythmia mediated TCM, where the arrhythmia can exacerbate or worsen heart failure (HF) or an underlying heart disease. Pure TCM has already been described as affecting almost 1 out of 10 patients admitted for de novo acute HF. The aim of our study was to compare pure TCM and de novo acute HF and structural heart disease patients in terms of mortality and cardiovascular (CV)-related hospitalizations. Methods and results Prospective, observational study enrolling all consecutive patients with a confirmed diagnosis of TCM and all patients admitted for de novo acute HF. The TCM diagnosis was suspected in all patients admitted for HF-related symptoms, an ejection fraction &lt;50% with concomitant persistent atrial or ventricular arrhythmia, and confirmed after clinical and echocardiographic recovery. Acute HF diagnosis was made in all patients with an ejection fraction &lt;50%, new HF-like symptoms, diagnosis of structural heart disease and no evidence of clinical or echocardiographic recovery. For each patient, all-cause death and CV-related hospitalizations were recorded. One-hundred-and-ten patients with TCM (61.8% males, 68 ± 13 years old) were propensity matched with a control population of patients with HF and structural heart disease (76.6% males, 71 ± 15 years old, 75% ischaemic heart disease). After a median follow-up of 5.1 years (1st–3rd quartile 2.6–7.0 years) TCM patients showed an overall higher estimate of survival when compared to HF patients (78% vs. 58%; P = 0.031; Figure 1A) but a lower estimate of time free from CV-related hospitalization (31% vs. 57%, P = 0.014; Figure 1B). TCM patients got most often readmitted for AF-related elective procedures (60.8% of all hospitalizations) such ablation procedures or elective cardioversion, TCM recurrence (13.7%), and elective coronary angiography (5.9%). On the other hand, HF patients got readmitted for HF worsening (40.9%), cardiac or vascular surgery (22.7%), and elective coronary angiography (9.1%). Propensity-score matched analysis confirmed the results for all-cause death (81% vs. 49%; P = 0.006) and CV-related hospitalizations (29% vs. 54%; P = 0.007). Conclusions TCM is associated with higher rate of survival when compared to de novo acute HF, even after propensity score adjustment. On the other hand, patients with TCM got readmitted more frequently, requiring more often elective procedures in order to control the triggering arrhythmia.

Abstract Background Takotsubo cardiomyopathy is a transient left ventricular dysfunction with an established recurrence rate in populations, however, recurrences in the same individual have not been well described. Case summary We present a 76-year-old woman who had likely a total of six recurrent takotsubo cardiomyopathy episodes spanning over 33 years. Her diagnosis of takotsubo cardiomyopathy was first made in 2014 when she presented with chest pain, raised cardiac enzymes, and the presence of normal coronary arteries. Cardiac magnetic resonance was performed, ruling out any current or previous myocardial infarction. Subsequently, she had two further recurrences in 2015 and 2018. Stressors were identified on three occasions. She was diagnosed with ‘myocardial infarction’ in 1986, 1988, and 1998 when she presented with chest pain and electrocardiogram changes, despite demonstrating normal coronary arteries on each occasion. Discussion This case demonstrates three confirmed recurrent episodes of takotsubo in the same individual, showing three different left ventricular phenotypic morphologies on the background of three previous episodes of ‘myocardial infarction with normal coronary arteries’, which most likely might have been takotsubo episodes as well. Any myocardial infarction-type injury was definitely ruled out in the 2014 admission instigating a potential change in this patient’s past medical history and implicitly requirement for lifelong secondary prevention. It is notably difficult to make a confirmed diagnosis of takotsubo cardiomyopathy back in 1986, 1988, and 1998 due to the lack of awareness in this novel topic.
