2024年2月6日 · In angiography and CTCA, the LCx is often described as having proximal and distal segments: Branches of the circumflex artery supply the lateral and posterolateral walls of the left ventricle. Most hearts are right dominant where the posterior descending artery (PDA) is supplied by the right coronary artery (RCA).

In the context of a Coronary Calcium Scan, which employs computed tomography (CT) to detect calcifications in the coronary arteries, the LCX is meticulously examined for signs of atherosclerotic plaque.

2015年12月26日 · FIGURE 3-8 Normal axial anatomy of the left main (LM) coronary artery, left anterior descending artery (LAD) and its branches, and left circumflex artery (LCX) and its branches on 64-slice CT coronary angiography at 0.625-mm collimation. Long thin arrowhead denotes the LAD, and short thick arrowhead denotes LCX.

2023年12月28日 · Left circumflex (LCx) arising from right coronary sinus (RCA) is a coronary arterial variant. It is considered the most common coronary anomaly with prevalence range of around 0.37-1.3 % of all patients. According to some publications, anomalous LCx is divided into 3 types 9. type II: common ostia in the right sinus.

We report two cases of rare left circumflex artery (LCX) anomalies: one case of absent LCX with super-dominant right coronary artery (RCA) and another of anomalous origin of LCX from right coronary sinus. Case 1: A 48-year-old woman presented with exertional dyspnoea. Echocardiography was normal.

2024年10月1日 · We aimed to evaluate coronary artery lesions (CALs) of the left circumflex artery (LCx) in KD on computed tomography coronary angiography (CTCA). Over a 9-year period (November 2013–December 2022), 225 children with KD underwent radiation-optimized CTCA on a 128-slice dual-source platform.

2011年5月26日 · The LCX gives off obtuse marginal branches (OM), which supply the lateralwall of the left ventricle. Occasionally, the left main artery can trifurcate into the LAD, the LCX, and a third vessel between the LAD and LCX termed the ramus intermedius artery.

2015年6月10日 · They are cardiac caths. They are not going to be in the same configuration as a CT. The one on the bottom right is showing a coronary anomoly where part of the left coronary artery comes from the right coronary cusp. It appears to be a LCx coming from the right but this could be the left main coming from the RCC.

We present a CTCA series on LCx involvement in KD highlighting novel anatomical findings. LCx CALs were detected on CTCA in 41/225 (18.2%) cases. TTE detected LCx CALs in only 15 of these 41 patients. CTCA emerges as an essential imaging modality for LCx evaluation.

2012年11月23日 · Electron beam CT image shows left main coronary artery (LMCA) dividing into left anterior descending artery (LAD) and left circumflex artery (LCx). Point of LMCA division is important anatomic landmark for delimitation of LMCA and LAD.
