The technical aspects of the procedure include a thorough clinical history and examination prior to angiography and knowledge of both the variations of coronary anatomy and equipment and drugs needed to carry out the procedure. Analysis of the angiogram should be based on an understanding of coronary...
Because coronary angiograms are obtained with digital imaging, immediate reviewing is possible during the procedure,which allows the operator to be confident or prompts him or her to obtain additional views. Digital subtraction angiographyis useful in imaging the aortic arch, where the background frame...
Initial angiogram showed TIMI 0 flow Initial angiogram showed thrombus grade of 5 The left main and left anterior descending arteries had no significant lesions. The stents in the LAD and D1 were patent The circumflex had no significant lesions. The stent in the first OM had a 50% le...
The validity of the videodensitometric method was analyzed in a series of Lucite phantom studies, which suggested that when there is an irregular angiographic appearance, the densitometric method may be more accurate than standard edge detection methods. Digital acquisition of coronary angiograms ...
An angiogram is an x-ray of the arteries that helps to show any blockages. An ECG is a test that measures the electrical activity of the heart and can indicate if there is any damage to the heart muscle. A stress test involves walking on a treadmill while hooked up to an ECG machine...
The culprit lesion was defined as the site of PCI, the tightest lesion, or the lesion with evidence of recent plaque disruption on coronary angiogram. In cases of multivessel PCI, the lesions with the highest degree of stenosis as assessed on angiogram were chosen as the culprit lesion, and...
Open heart bypass graft surgery is the standard treatment for advanced cases of coronary heart disease. Optimal placement of the bypass graft anastomosis is very important for the success of the procedure. Therefore, detailed and precise knowledge about the path and morphology of the target vessel ...
There was also a severe stenosis in the distal right-posterior descending artery with evidence of SCAD (Figure 4B, Video 3B). There was otherwise no intracoronary atherosclerotic plaque seen.
