to study the newly mentioned significance of the obstructive lesion morphology in coronary artery disease (cad), a study has been designed to compare this feature between patients having stable angina (sa) or unstable angina (ua) who underwent coronary angiography in tehran heart institute. study objectives were detection of the angina producing artery (ap a) and its morphologic lesion type, de...

AD, anterior descending coronary artery; CTO, chronic total occlusion; CX, circumflex coronary artery; F, female; LMC, left main coronary artery; M, male; RC, right coronary artery. a Patient no. 4 had chronic renal failure requiring hemodialysis, as well as severe peripheral arterial disease. Patient no. 7 had advanced chronic obstructive pulmonary disease. b Patient no. 4 had total occlusion ...

Significant unprotected left main coronary artery (ULMCA) disease occurs in 5-7% of patients undergoing coronary angiography [1,2] and patients with ULMCA disease treated medically have a three years mortality rate of 50% [3,4]. Advances in percutaneous intervention techniques and stent technology have allowed evolution of the role of percutaneous coronary intervention (PCI) for left main disea...

Coronary artery bypass surgery is considered as the gold standard treatment of unprotected left main coronary artery (ULMCA) disease. Over the last 20 years, improvement in stent technology and operators experience explained the increased number of reports on the results of percutaneous coronary interventions (PCIs) for the treatment of left main (LM) coronary artery lesion. The recent data com...

Obstructive lesions of the main left coronary artery (LCA) were demonstrated angiographically in 73 patients, comprising 4.3% of the total population referred to us for diagnostic evaluation of chest pain. Although there were no specific historical or clinical features which could absolutely distinguish this subgroup from the larger population of coronary artery disease patients, 81% (34/42) of...

OBJECTIVE To compare the coronary anatomy and the location of coronary lesions in monozygotic and dizygotic twin pairs affected with coronary artery disease. DESIGN Coronary angiographic findings were compared with respect to the distribution of coronary blood supply and the location of coronary lesions. MAIN OUTCOME MEASURES Distribution of coronary blood supply, diameters and length of pr...
