Branches from the first segment of
circumflex arteryA leison leading to 80% stenosis in
circumflex artery was observed and found to be suitable for concomittant bypass surgery on beating heart.
RESULTS ST-segment elevation in the posterior leads was twice as frequent during occlusion of the
circumflex artery as during right coronary occlusion (P < .
Smith said physicians tried to perform angioplasty Tuesday on Anderson's
circumflex artery, but ``it didn't work well'' because the blockage was ``too hard to penetrate.
Myocardial infarction due to left
circumflex artery LCx occlusion has been less studied in trials regarding ST elevation MI; this is mainly due to the absence of significant ST segment elevation on ECG.
Coronary angiography showed a chronic occlusion of the right coronary artery (RCA), and significant stenosis ([greater than or equal to] 75%) of the left anterior descending artery (LAD) and
circumflex artery (Cx).
Left main coronary artery stenosis area larger than 50% and left anterior descending branch, left
circumflex artery and right coronary artery stenosis area larger than 75% were taken as the evaluation criteria; large branches such as diagonal branch, obtuse marginal branch and right ventricular branch were attributed to left anterior descending branch, left
circumflex artery and right coronary artery.
The Left Main Coronary Artery (LMCA), Left Anterior Descending (LAD) and Left
Circumflex Artery (LCX) were found to be of normal origins with no signs of pre atherosclerotic lesions.
Of the total 7 cases with coronary artery anomalies of origin and course, 2 patients had origin of the
circumflex artery from the right coronary sinus, 2 patients had separate origin of the left anterior descending artery and
circumflex artery from the left coronary sinus, one patient had left coronary artery originating from right sinus of valsalva and one patient had left coronary artery originating from pulmonary artery (ALCAPA) and one patient had congenitally absent left
circumflex artery.
Tanigawa et al (14) reported the case of a patient with myocardial infarction who was found to have a periarterial mass with luminal narrowing of the left
circumflex artery and increased serum IgG4 level.
Coronary angiography revealed a small fistulous communication between the proximal
circumflex artery and the pulmonary artery (Fig.
Angiography revealed significant left anterior descending artery stenosis with neovascularization of the myxoma by both left
circumflex artery and right coronary artery (Fig.
