What is LCX in heart disease?

Background: Ostial disease of the left anterior descending (LAD) or circumflex (LCX) coronary artery is a challenge for the interventionalist. Focal ostial stenting may result in incomplete lesion coverage or plaque shift into the adjacent vessel, creating left main equivalent disease.

What is LCX in ECG?

The LMCA is short and branches into the two arteries supplying the anterior and left side of the heart, as follows: The left anterior descending coronary artery (LAD). The left circumflex coronary artery (LCX).

Is a blocked circumflex artery serious?

In less than half of people, it may also supply blood to the sinoatrial nodal artery. With anomalous coronary arteries, the circumflex artery or others may be deformed at birth. Such a defect can present a great danger to the child (especially if taking part in aerobic sports) as it can increase risk for heart failure.

Which artery is LCx?

Left Circumflex
The Left Coronary Artery has two major branches; they are called the Left Anterior Descending (LAD) and the Left Circumflex (LCx) coronary arteries. The LAD supplies blood and oxygen to the anterior portion of the left ventricle. The LCx supplies blood and oxygen to the lateral portion of the left ventricle.

Where is the LCx artery?

Description. The LCX follows the left part of the coronary sulcus, running first to the left and then to the right, reaching nearly as far as the posterior longitudinal sulcus. There have been multiple anomalies described, for example the left circumflex having an aberrant course from the right coronary artery.

Is the circumflex artery important?

The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.
