One hundred and eight patients with single and multiple vessel coronary artery disease confirmed by arteriography were evaluated by exercise thallium-201 (201Tl) myocardial scintigraphy to determine the scintigraphic appearances of specific coronary stenoses. In general proximal stenoses caused more widespread, but not necessarily more severe, myocardial tracer deficit than distal stenoses. In ...

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...

Multivessel or multisegment spasm in patients with known widespread coronary atherosclerotic disease is an infrequent occurrence. We describe a prolonged spasm of both the left main and the left anterior descending artery in a patient with chronic effort angina and multivessel coronary artery disease, who previously underwent percutaneous coronary intervention and drug eluting stents implantati...

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...

cor triatriatum   sinistrum is a rare congenital cardiac malformation, accounting for about 0.1-0.4% of all congenital heart diseases and characterized by the presence of a fibromuscular membrane that subdivides the left atrium into two chambers in the classical form. while classic cor triatriatum in most patients can be observed during the neonatal period or early infancy, it is very rare in a...

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...
