Branches from the second segment of circumflex artery
1) Furthermore, differentiation of occlusion of the circumflex artery
from occlusion of the right coronary artery (RCA) is often difficult because either may be associated with an ECG pattern of inferior AMI.
Unfortunately, the dissection seen in the circumflex artery
was unchanged and was thought to be the cause of the patient's symptoms.
In this study of five pigs, test animals underwent ameroid constriction placement on the circumflex artery
and were tested for intramyocardial effects of nicotine after induced ischemia was demonstrated in the target zone of the myocardium.
2a) and from the proximal left circumflex artery
(LCx) in 35 to 45% of the population (Fig.
The contribution from the posterior circumflex artery
was more variable, though a group of vessels was consistently found penetrating the bone-cartilage interface medially.
With no user input, the application automatically segments the Left Anterior Descending artery, the Circumflex artery
, and the Right Coronary artery.
Considering a high pre-test probability for coronary artery disease, he was scheduled for cardiac catheterization, which showed diffuse ectasia of his left circumflex artery
(10 mm in diameter) and left anterior descending artery (6 mm in diameter).
The distal left circumflex artery
was filled by collaterals from the distal right coronary artery (Figure).
Selective coronary artery angiography was performed to rule out ischemic heart disease and demonstrated a large, tortuous vessel arising from the circumflex artery
and bifid (Y) origin of the right coronary artery (Fig.
Furthermore, a lateral approach avoids potential injury to the ascending circumflex artery
, thereby preventing further loss of blood supply to the humeral head.
The perforation occurred in the context of multiple attempts to cross the totally occluded circumflex artery
, as the wire most likely dissected the circumflex artery
and penetrated the left atrial appendage.
