Left anterior descending coronary artery LAD

The first phase I clinical trial of coronary angiogenesis demonstrated the safety of intramyocardial injection of 0.01 mg/kg of FGF-I (79), A total of 40 patients undergoing CABG of the internal mammary artery (IMA) to left anterior descending coronary artery (LAD) were randomized to receive intramyocardial injections of either 0,01 mg FGF-1 or placebo. All the patients had further stenoses of the LAD distal to the anastomosis, Coronary angiography 12 weeks after treatment showed increased capillary refill in patients... 

The myocardium and specific conduction system (SCS) are perfused by the right coronary artery (RCA), the left anterior descending coronary artery (LAD) and the circumflex coronary artery (LCX). Figure 1.1 shows the great correlation of coronary angiography and CMDCT in normal coronary tree and some pathologic cases. 

Figure 4.10 In an acute coronary syndrome with ST-segment elevation in V1-V2 to V4-V6 as the most striking pattern, the occluded artery is the left anterior descending coronary artery (LAD). The correlation of the ST-segment elevation in V1-V2 to V4-V5 with the ST morphology in II, III and VF allows us to know if it is an occlusion proximal or distal to D1 (see Figure 4.43). If it is proximal, the involved muscular mass in the anterior wall is large and the injury vector is directed not only forward but also upward, even though there can be a certain...

A segment of the left anterior descending coronary artery (LAD), approximately two-thirds the distance from apex to base, is isolated and a silk ligature is placed around the segment. 

RCA or the LCX, depending on which of them is dominant (the RCA in >80% of the cases). Segment 15 often receives blood from LAD. (E) Correspondence of ECG leads with the bull s-eye image.

Figure 7. Cardiovascular response of a typical anesthetized dog to monensin. A low dose (0.05 mg/kg) was first introduced iv (dissolved in ethanol), and after an interval of an hour to permit the animal to return to basal conditions, a higher dose (0.2 mg/kg) was administered. The lowest tracing (mean LAD C.F.) is the time-averaged flow measured by a magnetic flow probe encircling the left anterior descending coronary artery. The A P trace gives the diastolic-systolic pressure range recorded from a catheter in the aorta. LV dP/dt max, the index of cardiac contractility, was obtained from a manometer-tipped catheter inserted in the left ventricle. The measured pressure was converted to its derivative to record dP/dt...

Two-vessel coronary artery disease (60% right coronary artery [RCA] and 80% left anterior descending artery [LAD] occlusion) after intracoronary CYPHER stent placement to the mid-LAD artery lesion 10 months ago. 

In Fig. 2.2, the PET perfusion images show severe stenosis or occlusion of the left circumflex (LCx) and right (RCA) coronary arteries with a moderately severe stenosis of the left anterior descending (LAD) coronary artery proximal to its second diagonal branch. The ejection fraction (EF) and regional LV contraction were normal. Therefore, this example illustrates purely ischemic myocardium without scar and without injured or poorly contracting myocardium.

A EXPERIMENTAL FIGURE 18-21 Atherosclerosis narrows and blocks blood flow through coronary arteries. X-ray multislice computed tomographic image of a human heart reveals a major occlusion (black arrow) of the left anterior descending artery (LAD, arrow) and a narrowing of a nearby vessel (white arrow) as a block in the stream of blood (seen in the arteries as a white tube).
