Cardiac computed tomography (CT) images sometimes show a donut-like oval structure on the antero-superior wall of the left atrium (LA). What is a donut? Left atrium diverticula (LADs) are common, but there are many unknown features of LADs. The direct effects of pulmonary vein thrombi (PVTs) on the heart are poorly understood. Herein, we report a case report in which we describe the different effects of edoxaban on LA thrombi, the LAD, coronary artery collaterals, early repolarizations, and end-QRS notches using cardiac CT and transesophageal echocardiography (TEE). First, we showed that there was a LAD on the anterior wall of the LA where the LA thrombi from the right lower pulmonary vein (RLPV) thrombi were connected. To our knowledge, this is the first report to reveal LAD's annular transformation and the beneficial effect of edoxaban on the end-QRS notch.

The electrocardiographic pattern of early repolarization (ER) is relatively common in the general population. In patients presenting to the emergency room with chest pain, it can be particularly challenging to distinguish ER from life-threatening subtle ST-segment elevation myocardial infarction (STEMI). A 37-year-old male presented to the emergency department with sudden-onset, severe, non-radiating, central chest pain.

Background: Early repolarization (ER) pattern on ECG is associated with an increased mortality in Caucasians. This study analyzed the association between ER pattern and all-cause mortality in a population of multiple ethnicities.
Methods: A total of 20 000 individuals were randomly selected and their ECGs were analyzed for ER pattern using the 2015 consensus: end-QRS notching or slurring with a J-point (Jp) ≥0.

Early repolarization pattern (ERP) is a frequent finding in asymptomatic subjects with controversial implications regarding to its prognosis. This study aims to estimate the prevalence of ERP and its association with sociodemographic characteristics and cardiovascular risk factors among the adult population in the Southern Cone of Latin America. A sub-sample of 5398 participants of the CESCAS I study was included in the present analysis.

Six ECG patterns are found more frequently in healthy black adults than in whites. These patterns are presumably benign, but also may resemble those of malignant disease. 1) Healthy black adults show higher QRS voltage, and more often meet ECG criteria for left ventricular hypertrophy (LVH).
