Computed tomography coronary angiography (CTCA) has entered the level of daily clinical practice in many institutions worldwide. All studies previously performed on the diagnostic accuracy of CTCA have shown a high negative predictive value, indicating a high ability of this method to exclude relevant coronary artery disease.1–3 However, CTCA is highly demanding not just of the technology, but… View more

Measuring Left Ventricular Ejection Fraction - Techniques and Potential Pitfalls
Author(s): Thomas A Foley , Sunil V Mankad , Nandan S Anavekar , et al Added: 12 years ago
Left ventricular ejection fraction (LVEF) is one of the most commonly reported measures of left ventricular (LV) systolic function. It is the ratio of blood ejected during systole (stroke volume) to blood in the ventricle at the end of diastole (end-diastolic volume). If the LV end-diastolic volume (EDV) and end-systolic volume (ESV) are known, LVEF can be determined using the following equation:… View more

Myocarditis is difficult to diagnose due to its heterogeneous clinical presentation. Patients often present with nonspecific symptoms and there is no easy-to-use and widely available diagnostic test. Although the clinical manifestations of myocarditis are heterogeneous, up to one-third of cases progress toward dilated cardiomyopathy (DCM).1,2 Myocarditis is a major cause of DCM, which is a… View more

Contemporary Techniques for TAVI in Complex Patients
Author(s): Didier Tchétché , Kendra J Grubb , Darren Mylotte , et al Added: 1 year ago
This symposium, part ofTranscatheter Interventions Online 2023, and chaired by Dr Didier Tchétché (Clinique Pasteur, Toulouse, FR),presented and discussed the importance of first valve selection. The faculty considered why the choice of the first valve matters in younger and lower-risk patients with longer life expectancy. They also showed how the technical refinements in implementation are going… View more

Atrial Fibrillation in the Post-AFFIRM Era
Author(s): Todd Rudo Added: 3 years ago
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice, with a prevalence that substantially increases with age. Both the loss of atrial mechanical function and a rapid, irregular ventricular response contribute to potentially significant symptoms, including palpitations, fatigue, chest discomfort, light headedness or syncope. Additionally, AF is associated with a… View more

Goals in Pulmonary Arterial Hypertension Treatment Pulmonary arterial hypertension (PAH) arises from pathological thickening, obstruction and constriction of the pulmonary arterioles.1 This leads to progressive elevation of pulmonary pressures initially on exertion, then at rest.2 Symptoms present late, often only when the pressures can rise little further and the cardiac output (CO) falls due… View more

Myocardial infarction (MI) is associated with acute risk of early malignant arrhythmias that can be easily treated during in-hospital intensive care by defibrillation, adjuvant antiarrhythmic therapy or even catheter ablation in resistant cases. Indeed, such management resulted in substantial improvement in MI survival rate. Despite the implementation of primary percutaneous coronary… View more

2D echocardiography (2DE) is a common diagnostic and treatment planning tool in clinical cardiology, especially for the assessment of left ventricular (LV) volume and function. However, traditional 2DE is severely limited by its dependence on geometrical assumptions, which can lead to inaccuracies in volume quantification.1 Because 3D echocardiographic (3DE) imaging eliminates geometrical… View more

Myocardial revascularisation in patients with stable chronic angina is performed with the aim of reducing cardiovascular death, reducing myocardial infarction (MI) and relieving angina symptoms. However, contrary to expectations, modern therapy with percutaneous coronary intervention (PCI) has not had a significant impact on hard outcomes.1–5 Indeed, as also summarised in a recently published… View more
