The diagnostic and therapeutic challenge of atrial flutter in children: a case report.

Background: Palpitations represent a common cause for consultation in the pediatric Emergency Department (ED). Unlike adults, palpitations in children are less frequently dependent from the heart, recognizing other causes.

Case Presentation: A 11-year-old male came to our pediatric ED for epigastric pain, vomiting and palpitations.

Echocardiography in Advanced Heart Failure for Diagnosis, Management, and Prognosis.

Advanced heart failure, an end-stage disease characterized by high mortality and morbidity despite standard medical therapy, requires various therapeutic strategies like heart transplant and long-term mechanical circulatory support. Echocardiography is the main imaging technique to identify transitions to advanced stages of disease and guide risk stratification and therapeutic decision-making processes. Progressive development of advanced echocardiographic techniques allows more comprehensive assessment of the hemodynamic and structural profiles of patients with advanced heart failure, and its use in clinical practice continues to expand.

Left Ventricular Assist Device Implantation in a Thrombosed Apical Aneurysm.

Left ventricular assist device implantation is a challenging procedure in the presence of a giant thrombosed aneurysm, and no standard surgical techniques are currently recommended in this setting. In this case, we report the successful implantation of a left ventricular assist device (HeartMate III) in a patient with a massive thrombosed apical aneurysm. The patient presented with extended antero-apical necrosis as a result of a delay in hospital admission for acute coronary syndrome due to the patient's concerns about the COVID-19 pandemic outbreak.

Safety and feasibility of upper limb cardiopulmonary exercise test in Friedreich ataxia.

Aims: To explore the feasibility of upper limbs cardiopulmonary exercise test (CPET) in Friedreich ataxia (FRDA) patients and to compare the results with sex, age, and body mass index (BMI) matched cohort of healthy controls (HC).

Methods And Results: Cardiopulmonary exercise test was performed using an upper limbs cycle ergometer on fasting subjects. Peak oxygen uptake (peak VO2) was recorded as the mean value of VO2 during a 20 s period at the maximal effort of the test at an appropriate respiratory exchange rate.

Effects of Sacubitril/Valsartan on the Right Ventricular Arterial Coupling in Patients with Heart Failure with Reduced Ejection Fraction.

Background: right ventricle-pulmonary artery (RV-PA) coupling assessed by measuring the tricuspid anular plane systolic excursion (TAPSE)/pulmonary artery systolic pressure (PASP) ratio has been recently proposed as an early marker of right ventricular dysfunction in patients with heart failure with a reduced ejection fraction (HFrEF).

Methods: As the effects of sacubitril/valsartan therapy on RV-PA coupling remain unknown, this study aimed to analyse the effect of this drug on TAPSE/PASP in patients with HFrEF. We retrospectively analysed all outpatients with HFrEF referred to our unit between October 2016 and July 2018.

Beta-blocker therapy in heart transplant recipients: A review.

Beta-blockers are essential drugs for the treatment of many cardiovascular diseases, such as heart failure, acute and chronic ischemic heart disease, tachyarrhythmias, and hypertension. However, these drugs have not been used in cardiac transplant patients for many years owing to the fear that they could reduce cardiac output and functional capacity. In recent years, however, some evidence has shown that even in cardiac transplanted patients, β-blockers are useful and effective in the treatment of sinus tachycardia, supraventricular and ventricular tachyarrhythmias, left ventricular systolic dysfunction, and arterial hypertension.

Use of sacubitril/valsartan as 'bridge to transplant' in patients with end-stage hypertrophic cardiomyopathy.

The end stage or burned-out phase is an uncommon but challenging clinical evolution of hypertrophic cardiomyopathy (HCM). The management of end-stage HCM is empirically based on the use of drugs approved for heart failure with reduced ejection fraction; however, cardiac transplantation often represents the best option to improve survival. In our case, we describe the use of sacubitril/valsartan as a 'bridge to transplant' in a patient with end-stage HCM.

Beta Blockers Up-Titration in Patients with Heart Failure Reduced Ejection Fraction and Cardiac Resynchronization Therapy, a Single Center Study.

Clinical trials have shown the benefits of β-blockers therapy in patients with heart failure reduced ejection fraction. These benefits include improved survival and a reduced need for hospitalization. Cardiac resynchronization therapy has emerged as an essential device-based therapy for symptomatic patients with heart failure reduced ejection fraction despite optimal pharmacologic treatment.

A common polymorphism in the SCN5A gene is associated with dilated cardiomyopathy.

Aims: SCN5A is a disease-causing gene associated with familial dilated cardiomyopathy (FDC). We examined the possible association between a common polymorphism in the SCN5A gene (c.1673A>G-p.

Management of Arrhythmias in Heart Failure.

Heart failure patients are predisposed to develop arrhythmias. Supraventricular arrhythmias can exacerbate the heart failure symptoms by decreasing the effective cardiac output and their control require pharmacological, electrical, or catheter-based intervention. In the setting of atrial flutter or atrial fibrillation, anticoagulation becomes paramount to prevent systemic or cerebral embolism.

Pediatric Heart Failure: A Practical Guide to Diagnosis and Management.

Pediatric heart failure represents an important cause of morbidity and mortality in childhood. Currently, there are well-established guidelines for the management of heart failure in the adult population, but an equivalent consensus in children is lacking. In the clinical setting, ensuring an accurate diagnosis and defining etiology is essential to optimal treatment.

Exercise speckle-tracking strain imaging demonstrates impaired right ventricular contractile reserve in hypertrophic cardiomyopathy.

Aims: To analyse right ventricular (RV) systolic function in patients with hypertrophic cardiomyopathy (HCM) at rest and during exercise, and its possible correlation with left ventricular(LV) morphology and function.

Methods And Results: Standard echo, exercise stress echo, and RV 2D speckle-tracking strain (2DSE) were performed in 45 patients with HCM and in 45 age- and sex-comparable healthy controls. RV global longitudinal strain (GLS) was calculated by averaging local strains along the entire right ventricle.
