Objective: Coronary angiography data included in the analysis of operative mortality after coronary artery surgery are generally limited to left main coronary artery stenosis and classi®cation into one-, twoor three-vessel disease, but the role of stenoses and quality of distal runoff on each main coronary artery have never been analysed. The aim of this study was to assess the in ̄uence of coro...

A patient who presented with severe angina was found to have an ectopic origin of the entire left coronary system, the left main coronary artery arising from the proximal third of the right coronary artery. Atherosclerotic obstructive lesions were present in the right coronary artery, the left anterior descending artery, and the obtuse marginal branch of the left circumflex coronary artery. The...

A single left coronary artery with right coronary artery arising from either left main stem (LMS) or left anterior descending artery (LAD) or circumflex artery (Cx) is an extremely rare coronary anomaly. This is the first report of separate origins of proximal and distal RCA from LAD and circumflex arteries respectively in a patient with a single left coronary artery. This 57 year old patient p...

The left coronary artery displays variations in pattern, number and distribution of its branches. These variations influence the manifestation and extent of the coronary artery disease affecting the left main branch. A total of 100 North Indian cadaveric hearts were dissected to observe the main trunk of the left coronary artery. The main trunk of left coronary artery bifurcated, trifurcated an...

Patients with unprotected left main coronary artery (ULMCA) disease are considered at highest-risk of adverse cardiovascular events and mortality within the broad range of risk for patients with obstructive coronary artery disease (CAD). On the basis of several clinical and anatomic characteristics and patient/physician preference, individual patients with ULMCA disease might be treated with pe...

coronary artery disease is one of the main causes of mortality in most developed countries. there is also an increasing rate of mortality in developing countries where in addition to coronary artery disease, infection diseases still not have been controlled. although, now a day coronary artery disease is responsible for half of deaths in developed countries, this regrettable event is increasing...

BACKGROUND Most coronary artery anomalies are congenital in origin. This study angiographically determined the prevalence of different forms of anomalous aortic origins of coronary anomalies and their anatomic variation in a selected adult Lebanese population. Correlation between these anomalies and stenotic coronary atherosclerotic disease was also investigated. METHODS 4650 coronary angiogr...

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...

Resting 12-lead electrocardiographic records from 849 patients who underwent coronary cineangiographic studies were reviewed for U wave negativity without knowledge of the clinical data or angiographic results. In order to evaluate U wave negativity as an independent electrocardiographic sign, patients with significant Q waves in the anterior leads were excluded from the final data analysis lea...

Background: Coronary heart disease is a rising cause of adult death in Nepal. Diagnostic and interventional facilities such as coronary angiography and angioplasty have also collaterally improved in Nepal over the last decade. This study explores the most common coronary vessels involved in the Nepalese population based on the coronary angiographic findings. Methods: This is a retrospective stu...
