Percutaneous Coronary Intervention Paper

Improved Essays
Percutaneous coronary intervention (PCI) with stent implantation has been widely used for the treatment of coronary artery narrowing. Despite progress in stenting technique and stent itself, in some PCI cases, bifurcation lesions still remain challenging for cardiologists as they are more difficult to manage than simpler lesions. Clinically, stenting with bifurcation lesions is found to be associated with poorer post-PCI outcomes, which increases the need to evaluate side branches prior to PCI.
One of the poorer post-PCI outcomes is side branch occlusion. It is found that the patency rate of main vessel after implantation of drug eluting stent (DES) is satisfactory while side branch ostium still needs revascularization. When side branch occlusion occurs, it is found to be associated with intrinsic ostial disease, including stenosis and diffused plaque around ostium. In recent years, researchers continuously developed devices and stenting strategy to optimize PCI

The drive for automatic side branch analysis motivated many researchers to develop new methods. Wang et al. have presented a fully automated method for side branch detection, which has been proved effective to help decide optimal stenting strategy, select stent and evaluate PCI results at follow-up. It is noted by Karanasos et al. that in bifurcation assessment, the evaluation of side branch ostium could speed up lesion analysis and reduce contrast volume which could possibly improve patients’ comfort. Despite the critical role the evaluation of side branch ostium may play in the treatment of bifurcation lesions, to the best of our knowledge, no method has been presented to precisely identify not only the side branch, but also its ostium. Thus the aim of this study was to provide a novel method which identifies the side branch as well as its ostium and conducts vessel measurements

    The medical perfusionist field requires you to first complete perfusion training programs,which takes around four years to complete, then a four year Bachelor's degree, then trying to get accepted into the (PCP), or the Perfusion Certificate Program. Many perfusionists' goals are to pursue a certain certificate Medical Perfusionist program that best suits their needs. Nevertheless, many perfusion educational programs can also require candidates to complete a few mandatory courses in: college-level science, English, math and may also prefer other candidates with the following majors: physiology, biology, chemistry and/or anatomy versus those who do not have the experience. Some other major programs will prefer qualifying candidates to have…

    These substances created blockages and narrow the coronary vessels in a way that reduces blood flow. Atherosclerosis involves a repetitious inflammatory response to injury to the artery wall. Atherosclerosis begins as fatty streaks of lipids that are deposited in the intima of the arterial wall. These lesions commonly begin early in life. Not all fatty streaks later develop into more advance lesions.…

    Preoperative evaluation Cardiac surgery, including coronary artery bypass grafting and surgery for valvular disease, represents one of the most common classes of surgical procedures performed worldwide. Advances in the percutaneous management of coronary artery disease as well as in cardiac surgical techniques have led to improved outcomes with consequent longer life expectancy for patients. Greater numbers of patients with depressed left ventricular function, multiple comorbidities, failed interventional procedures, and prior revascularization operations are now referred for cardiac surgery. As a result, preoperative risk assessment is even more critical to ensure the safe performance of cardiac surgical procedures and the achievement…

    The flow ratios with adenosine challenge were 0.6 and, prior to that, in the range of 0.7. With the above noted, a 2.75 Penta stent was deployed, 13 mm in length. The lesion was hard; there was calcium. I had to take the stent up to 12 atmospheres in order to fully expand the balloon, and ensure good deployment. The stent was deployed without complication, and there was good flow established. The distal left main was assessed closely in view of passing a stent by the left main lesion, and there was no disruption of this area.…

    INTRODUCTION The aim of this review is to employ relevant primary literature resources to discuss the potentials of multidisciplinary cardiopulmonary care teams in cardiovascular life support and resuscitation towards patient mortality reduction and achievement of positive neurological outcomes after a cardiopulmonary arrest. Cardiovascular disease is the leading cause of more than 17.3 million annual deaths, representing 31% of global mortality rate, with nearly 801000 American deaths resulting from cardiac arrest in 2013 (WHO, 2016 & Mozaffarian et al., 2016). Similar trend exists in Ireland with 10000 reported cases of cardiovascular related deaths and associated 5000 annual cardiac arrest mortality (IHF, 2016).…

    People more than likely to endure elevated anxiety and all the other effects tide to anxiety when they decide to go through with cardiac catheterization. This anxiety usually occurs before, during and after but most likely before the procedure begins. It can negatively impact the individual psychologically when their anxiety has sky rocketed to unhealthy or nearly inconsolable heights. This behavior may potentially influence the subsequent procedure in a negative way. Research and study evaluated that the use of music therapy, emphasizing specifically on emotional-coping approach, immediately before the cardiac catheterization can lead to a to a more positive impact regarding periprocedural outcomes.…

    Coronary Bypass surgery is necessary when blood vessels that supply the heart with blood, to make it pump blood to the rest of the body are damaged. A couple of ways that the blood vessels become damaged by narrowing of the artery or veins. The narrowing occurs when fatty deposits, cholesterol or plaque clog the inside of the vessel causing poor blood supply to the heart. This type of illness may cause the heart to infarct, which means the heart muscle itself begins to die. Depending on the number of damaged blood vessels determines what type of surgery will be done, if you need one vessel repaired its called a single coronary bypass if it’s called a quadruple coronary bypass, the you need for vessels repaired.…
