Prominent crista terminalis is a variant of normal heart anatomy mimicking right atrial mass-like tumour, thrombus, or vegetation. The case report depicts a rare kind of this structure that constitutes a thick muscular bridge in the right atrium. Detection by 2D and 3D echocardiography can avoid further useless investigation.

Article Synopsis
  • The exact causes of common atrial flutter are not fully understood, particularly regarding arrhythmia triggers and the impact of slow-conducting heart tissue.
  • A detailed electrophysiological study was conducted on a patient to investigate how this arrhythmia starts and is maintained, utilizing techniques like electro-anatomical mapping.
  • The study found that common atrial flutter begins with a unidirectional conduction block at the septal cavo-tricuspid isthmus, resulting in a counter-clockwise activation pattern and stabilization near specific heart regions, without any slowing of conduction.

Atrial flutter and sick sinus syndrome.

Article Synopsis
  • Sick sinus syndrome (SSS) can lead to serious health issues like fainting and the need for pacemakers, and researchers wanted to see if atrial flutter (AFL) could predict SSS better than other factors.
  • The study analyzed data from over 29 million adults in California from 2005 to 2019, focusing on those diagnosed with AFL and atrial fibrillation (AF) while adjusting for various demographics.
  • Results showed that both AFL and AF significantly increased the risk of developing SSS, with AFL notably heightening the risks of syncope and needing a pacemaker in patients already diagnosed with AF.

Article Synopsis
  • Crista terminalis is a fibromuscular ridge in the right atrium that separates smooth and muscular regions, and when prominent, it can be mistaken for thrombus or tumors.
  • Accurate differentiation between crista terminalis and other masses is essential to avoid misdiagnosis and unnecessary anxiety for patients.
  • The case highlights the use of two-dimensional and three-dimensional transesophageal echocardiography to identify the unique features of a prominent crista terminalis.

Atrial tachycardia originating from a right atrial free wall diverticulum: case report.

Eur Heart J Case Rep

October 2024

Department of Cardiovascular Medicine, The Second Xiangya Hospital of Central South University, 139 Renmin Road, Changsha City, Hunan Province 410000, China.

Background: Atrial tachycardia (AT) is an arrhythmic disorder originating from the atrium, independent of the atrioventricular node, and includes various types based on different mechanisms such as abnormal automaticity, triggered activity, and re-entry. These mechanisms are often related to specific anatomical structures. Focal AT, though relatively rare, typically arises from well-known locations in the left and right atria, such as the pulmonary veins, mitral valve annulus, crista terminalis, and coronary sinus ostium.

Aim: To quantitatively evaluate the relationship between the anatomical parameters of the right atrium and the recurrence of atrial fibrillation (AF) after radiofrequency ablation, considering different types of AF, utilizing 256-slice spiral computed tomography (CT).

Materials And Methods: A total of 297 patients with AF who underwent initial radiofrequency ablation were enrolled, divided into the paroxysmal atrial fibrillation (PaAF) group (n=230) and the persistent atrial fibrillation (PeAF) group (n=67). Subsequently, patients in each group were further stratified into recurrent and non-recurrent subgroups.
