Percutaneous coronary intervention in the setting of coronary bifurcation lesions is associated with increased risk for complications. The goal of this manuscript is to review the currently available classifications for coronary artery bifurcation lesions with a guide to the use of specific coronary bifurcation techniques based on lesion characteristics

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...
Background: Kawasaki disease (KD) is an acute vasculitis in children. Eosinophilia, a reflection of the host's immune response that can cause tissue damage, has been associated with KD, with eosinophils preferentially accumulating in the microvasculature. In early-stage Kawasaki disease (KD), lesions (perivasculitis and vasculitis) first form in the microvessels, which can then extend to the la...
Background and Objective: Thrombolysis in myocardial infarction (TIMI) frame count (TFC) is an objective and quantitative index of coronary flow, and myocardial fractional flow reserve (FFR) is a lesion-specific index for epicardial coronary stenosis. Currently, FFR is the most valid tool for decision making in coronary interventions. However, it incurs relatively high costs and it is not reimb...
In the past, coronary artery bypass grafting was the treatment of choice for patients with symptomatic multi vessel coronary artery disease, but in recent years per cutaneous transluminal coronary angioplasty (PTCA) accepted as an alternative approach to revascularization. To assess the initial success and in hospital results of coronary angioplasty of more than one lesion per procedure in pati...

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...
Introduction : Significant left main coronary artery stenosis jeopardizes the entire myocardium of the left ventricle and has the worst prognosis of any form of coronary artery disease. Coronary-artery bypass grafting (CABG) has been considered as the standard therapeutic approach for such patients. There are limited data on the safety and effectiveness of percutaneous coronary intervention (PC...
