Dual left anterior descending (LAD) artery is a rare anomaly conventionally classified into 4 types. We present a case of dual LAD artery in which the long LAD artery has arisen from the left circumflex (LCx) artery, a condition not previously included in the 4 defined types. Moreover, the long LAD artery specified here is associated with an intramyocardial coronary aneurysm. To our best knowledge, it is the first time such a coronary artery anomaly has been reported. This case suggests the important role of coronary computed tomography angiography (CTTA) for diagnosis and therapeutic planning for such an anomaly.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

Myocardial ischaemia is a decompensation of the oxygen supply and demand ratio, often caused by coronary atherosclerosis. During the initial stage of ischaemia, the electrical activity of the heart is disrupted, increasing the risk of malignant arrhythmias. The aim of this study is to understand the differential behaviour of the ECG during occlusion of both the left anterior descending (LAD) and right anterior coronary artery (RCA), respectively, using spatio-temporal quantifiers from information theory.

Both de Winter syndrome and Wellens syndrome mainly indicate severe stenosis in the proximal segment of the anterior descending coronary artery. However, as research deepens, the accuracy and specificity of diagnosing proximal left anterior descending coronary artery (LAD) culprit lesions separately by de Winter syndrome or Wellens syndrome are challenged. The patient in this case developed both syndromes in a short period of time, and imaging showed significant stenosis of the proximal LAD, indicating a culprit lesion.

Spontaneous coronary artery dissection (SCAD) is a rare condition that frequently goes undiagnosed. Still, it is becoming an increasingly recognized cause of acute coronary syndrome (ACS), predominantly in middle-aged women with few or no cardiovascular risk factors. We present a case of a 53-year-old female with traditional cardiovascular risk factors, who presented with typical anginal symptoms and was diagnosed with SCAD in the mid to distal left anterior descending artery (LAD).
