The Impact of Advances in Atrial Fibrillation Ablation Devices on the Incidence and Prevention of Complications

Catheter ablation is an effective strategy to maintain sinus rhythm in patients with symptomatic atrial fibrillation (AF), which has evolved from a highly specialised technique to a first-line therapy.1–3 The cornerstone of ablation is pulmonary vein isolation (PVI).4 Over the last decade, ablation devices have undergone technical improvements, aiming for better lesion durability and ablation outcomes.

Source Determination in Atrial Fibrillation

Catheter ablation of AF has shown steady growth over the past two decades with a nearly 15 % annual increase in the US.1 This growth can be attributed in large part to four factors: an increase in operators and institutions performing the procedure;2 a steady rise in AF prevalence, which is predicted to reach 12 million in the US by 2030;3 a larger spectrum of AF patients with more complex atrial substrates being offered ablation;

Reduction of Fluoroscopy Time and Radiation Dosage During Catheter Ablation for Atrial Fibrillation

The number of catheter ablations for atrial fibrillation (AF) treatment has gradually increased over the last 15 years since the first report on the importance of pulmonary vein (PV) foci for triggering AF.1 Catheter ablation for AF is a complex procedure with multiple steps, such as transseptal puncture, mapping of the left atrium and PVs and extensive linear ablation around PV ostia.

Holter Monitoring and Loop Recorders: From Research to Clinical Practice

Since the 1960s, Holter monitoring has been a cornerstone for diagnosing suspected arrhythmias in patients of all ages.1 The most common monitoring systems allow the continuous registration of three or more leads for 24–48 hours; newer Holter monitors allow continuous electrocardiogram (ECG) registration for 2 weeks.1 Extending the time of ECG registration will increase the diagnostic yield of Holter monitoring, especially for those rhythm disturbances that are infrequent but recurrent.1,2 This need for a prolonged ECG monitoring has been a

Advances in Cardiovascular MRI using Quantitative Tissue Characterisation Techniques: Focus on Myocarditis

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 significant cause of heart failure and sudden cardiac death in young adults.3 DCM due to myocarditis is the major underlying reason for cardiac transplantation.
