A 16-month-old, healthy, asymptomatic male child presented with a diagnosis of dilated cardiomyopathy. Cardiovascular examination and chest radiograph were normal. ECG revealed sinus rhythm, and the augmented vector left lead showed raised ST segment, T wave inversion and q waves. Echocardiography showed a globular left ventricle with notched cardiac apex, abnormal echogenicity in the left ventricular apical myocardium, single papillary muscle and normal biventricular function. Cardiac MRI scan revealed a globular left ventricle with fibrofatty changes and retraction of the apex, the papillary muscles closely approximated, and the right ventricle wrapping around the apex of the left ventricle. This is described as isolated left ventricular apical hypoplasia. Diagnosis of this rare entity can be made by MRI, and it has been diagnosed largely in adults. The pathophysiology and long-term outcomes are unknown. We characterise the echocardiography findings of this rare anomaly in a child for the first time in the literature.

Negative Predictor

The article presents a clinical observation of myocardial infarction (MI) of the inferior wall of the left ventricle (LV) with ST-segment elevation in combination with damage to the right ventricle (RV). Unfortunately, there is often a delay in the timely diagnosis of RV involvement in the process. This is because, at the beginning of the symptoms, it may not differ clinically from the typical manifestations of MI of the inferior-diaphragmatic region of the LV. However, the combination of LV inferior wall MI with RV MI is an important, negative predictor of increased mortality in these patients. In this case, RV MI was diagnosed after stenting of the right coronary artery, only when signs of hypotension and increased pressure of the jugular veins appeared. Based on the analysis of this clinical case, the authors discuss the need to record an ECG of the right heart in most patients with inferior MI, especially in the presence of hypotension without signs of acute left ventricular failure.

The Mean

Objectives: We evaluated in-hospital and long-term outcomes of patients who underwent primary percutaneous coronary intervention (PCI) in a tertiary center. Patients and Methods: We examined 1550 patients (mean age: 58.5 years, 83.1% male) admitted with acute ST-segment elevation myocardial infarction (AMI) who underwent primary PCI and were followed-up prospectively. The primary outcomes were in-hospital death and major adverse cardiac events (MACE) at follow-up. Results: The mean duration of ischemia at admission was 2.85 ± 2.49 hours; and the mean door-to-device time was 43.2 ± 20.3 minutes. During hospitalization, all-cause mortality occurred in 73 patients (4.7%). Multivariate analysis revealed that advanced age, impaired left ventricular ejection function, high Killip functional class, hemoglobin level at admission, ventricular arrhythmias, and advanced atrioventricular block were independent predictors of poor prognosis (OR: 1.07, 0.93, 15.34, 1.44, 3.79, and 4.26, respectively). Among discharged patients with a median follow-up of 49.5 (25‒73) months, 12.4% experienced all-cause mortality, 12.5% had recurrent myocardial infarction (MI), and 2.3% had a cerebrovascular accident. The strongest independent MACE predictors were impaired left ventricular function, poor glomerular filtration rate, low albumin level, and a history of cerebrovascular disease (HR: 0.97, 0.99, 0.65, and 2.50, respectively). Secondary outcomes were contrast-induced acute kidney injury (16.7%), ventricular arrhythmias (6.1%), advanced atrioventricular block (3.7%), atrial fibrillation (7.6%), and major bleeding (1.6%). Conclusion: AMI still has a poor long-term prognosis. These results emphasize the advantages of rapid, non-delayed revascularization. Patients should be followed-up closely after discharge in both the short- and long-term.

Recently, there has been a tendency to increase the incidence of myocardial infarction without elevation of the ST segment, which, according to some data, accounts for about half of all registered MI. The main problem with this type of infarction is that the long-term prognosis in these patients remains unsatisfactory, and mortality one year after the catastrophe is equal to or even higher than mortality from ST-segment elevation myocardial infarction, which encourages continued predictors of unfavorable prognosis. Objective: to determine the gender characteristics of the structural and geometric remodeling of the left ventricle in patients with myocardial infarction without ST segment elevation. Materials and methods. We conducted a comprehensive study of 200 patients with acute myocardial infarction without ST-segment elevation (NSTEMI) aged 38 to 80 (mean 62.0 ± 0.71, median 62 and interquartile range 55 and 70). The structural and functional state of the myocardium and types of left ventricular remodeling according to transthoracic echocardiography were studied. Results. Analysis of the obtained data shows that echocardiographic parameters in patients with NSTEMI depending on gender did not reveal significant differences between different groups. The exception was the size of the right atrium, which was significantly higher in the group of men compared to women with comparable values of the size of the right ventricle and the ratio of the size of the left to the right atrium. Analysis of the nature of structural and geometric remodeling of the left ventricle in general by groups showed that almost half of the subjects registered concentric hypertrophy of the left ventricle. Concentric left ventricle remodeling was observed in one third of patients and in other patients - normal geometry and eccentric left ventricle hypertrophy. Thus, it was found that concentric models of left ventricle – concentric hypertrophy and concentric remodeling – were registered in the vast majority of patients with NSTEMI. The latter can be explained by a significant proportion of hypertension which was identified by us in most patients and, of course, contributed to the development of concentric models of left ventricle. Analysis of the nature of structural and geometric remodeling of the left ventricle depending on gender showed that in the group of men, compared with women, there was a significant increase in the incidence of concentric remodeling. At the same time, in women, compared with men, there was a significant increase in cases of more severe types of structural remodeling - concentric and eccentric hypertrophy. Thus, we found that gender differences in echocardiographic parameters in patients with NSTEMI relate exclusively to indicators of structural and geometric remodeling of the left ventricle. Signs of concentric and eccentric left ventricular hypertrophy predominate in women, and indicators of normal geometry and concentric left ventricular remodeling in men. This distribution of types of remodeling indicates a more severe course and unfavorable prognosis of NSTEMI in women.

Acute myocardial infarction (AMI) resulting in cardiogenic shock continues to be a substantial source of morbidity and mortality despite advances in recognition and treatment. Prior to the advent of percutaneous and more durable left ventricular support devices, prompt revascularization with the addition of vasopressors and inotropes were the standard of care in the management of this critical population. Recent published studies have shown that in addition to prompt revascularization, unloading of the left ventricle with the placement of the Impella percutaneous axillary flow pump can lead to improvement in mortality. Parameters such as the cardiac power output (CPO) and pulmonary artery pulsatility index (PAPi), obtained through pulmonary artery catheterization, can help ascertain the productivity of right and left ventricular function. Utilization of these parameters can provide the information necessary to escalate support to the right ventricle with the insertion of an Impella RP or the left ventricle with the insertion of larger devices, which provide more forward flow. Herein, we present a case of AMI complicated by cardiogenic shock resulting in biventricular failure treated with the percutaneous insertion of an Impella RP and Impella 5.0 utilizing invasive markers of left and right ventricular function to guide the management and escalation of care.

AbstractBoth acute myocardial infarction complicated by ventricular tachyarrhythmias (AMI–VTA) and electrical storm (ES) represent life-threatening clinical conditions. However, a direct comparison of both sub-groups regarding prognostic endpoints has never been investigated. All consecutive implantable cardioverter-defibrillator (ICD) recipients were included retrospectively from 2002 to 2016. Patients with ES apart from AMI (ES) were compared to patients with AMI accompanied by ventricular tachyarrhythmias (AMI–VTA). The primary endpoint was all-cause mortality at 3 years, secondary endpoints were in-hospital mortality, rehospitalization rates and major adverse cardiac event (MACE) at 3 years. A total of 198 consecutive ICD recipients were included (AMI–VTA: 56%; ST-segment elevation myocardial infarction (STEMI): 22%; non-ST-segment myocardial infarction (NSTEMI) 78%; ES: 44%). ES patients were older and had higher rates of severely reduced left ventricular ejection fraction (LVEF) < 35%. ES was associated with increased all-cause mortality at 3 years (37% vs. 19%; p = 0.001; hazard ratio [HR] = 2.242; 95% CI 2.291–3.894; p = 0.004) and with increased risk of first cardiac rehospitalization (44% vs. 12%; p = 0.001; HR = 4.694; 95% CI 2.498–8.823; p = 0.001). This worse prognosis of ES compared to AMI–VTA was still evident after multivariable adjustment (long-term all-cause mortality: HR = 2.504; 95% CI 1.093–5.739; p = 0.030; first cardiac rehospitalization: HR = 2.887; 95% CI 1.240–6.720; p = 0.014). In contrast, the rates of MACE (40% vs. 32%; p = 0.326) were comparable in both groups. At long-term follow-up of 3 years, ES was associated with higher rates of all-cause mortality and rehospitalization compared to patients with AMI–VTA.
