Congenital absence of left circumflex artery
associated with constrictive pericarditis and thoracostomach.
Diagnostic coronary angiography revealed distal left main trifurcation disease including significant stenosis in the distal left main trunk (LMT), ostial left anterior descending artery (LAD), and ostial left circumflex artery
(LCX) (modified Medina classification 1-1-1-0) (Figure 1) .
CAG findings [Figure 1]c,[Figure 1]d,[Figure 1]e showed a 30% stenosis in the proximal left anterior descending artery, a 30-40% stenosis in the proximal left circumflex artery
, and one patent stent in mid-RCA with mild in-stent neointimal hyperplasia.
The advocates of the posterior approach believe that most femoral head dislocation fall into the category of the posterior dislocation, in which the simultaneous posterior capsular lancinate usually occurred and the blood supply for the femoral head from the medial femoral circumflex artery
would be destroyed.
Conclusion: This study shows that patients of acute inferior wall MI undergoing primary percutaneous coronary intervention (PCI) who have left circumflex artery
as culprit vessel have a poor prognostic outcome as compared to patients having right coronary artery as culprit vessel.
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
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.
However, axillary artery branching patterns are extremely variable and mostly subscapular artery and posterior circumflex artery
are involved in the variations (Hattori et al, 2013).
On MSCTA (320-sclice), a completely total occlusion of the left circumflex artery
proximal segment and critical stenosis (98%) at the middle segment of LAD were detected and invasive coronary angiography was performed on the same day.
Patients with pacemakers had decreases in stenosis of 10%-15% in the left anterior descending artery, the circumflex artery
, and the right coronary artery.
Patients with pacemakers had 10%-15% decreases in stenosis in the left anterior descending artery, the circumflex artery
, and the right coronary artery, Patients in the control group had increases of about 15% in stenosis in the three arteries.
A 71-year-old man with progressive angina was found to have severe stenosis in the circumflex artery
and complex CTO of the left anterior descending artery (Figure 1, Supplementary Video 1).
