A case of a previously fit young woman admitted with chest pain, who was found at coronary angiography to have dissection of the left main stem which extended to the left anterior descending and circumflex coronary arteries, is presented. Emergency coronary artery bypass grafting was performed (vein grafts to the left anterior descending, the diagonal, and circumflex arteries). The patient made...

Coronary artery bypass grafting has not been previously reported in the Nigeria medical literature. We report the case performed in our institution of a 56 year old Nigerian female who underwent off pump coronary artery bypass surgery (OPCAB) for an ostial lesion of the left anterior descending coronary artery. The left internal mammary artery was successfully anastomosed to the left anterior d...

Myocardial bridging (MB) is defined as a coronary artery that tunnels through the myocardium, under overlying muscle bridge. It almost exclusively affects left anterior descending (LAD), especially middle part (midLAD).

The size of the perfusion defect was assessed from a quantitative analysis of exercise thallium201 images. Quantitative analysis was determined by measuring the area and the perimeter of the perfusion defect and expressing it as a percentage of the total left ventricular area or perimeter in three projections. Using this technique, we studied 50 patients with one-vessel disease of50% or greater...

A 64-slice computed tomography (CT)—coronary angio-graphy depicted a saccular aneurysm of the left coronary artery located at the bifurcation of the left main into the left anterior descending artery and the left circumflex artery (Fig. 1A). Coronary angiography confirmed the diagnosis (Fig. 1B). The LAD and CX themselves originated directly from the neck of the aneurysm (Fig. 2A and B). Fig. 1...
