However, despite the frequency of its usage, research has found that the main limitation of this procedure is restenosis which has been defined as renarrowing of the original arterial lesion at the site of dilatation. Most of the data indicate that around 35% of the patients have restenosis and within six months following the angioplasty procedure (Savage et al., 1998). To improve this statistic and to improve the life-threatening complications following angioplasty or to back up and improve the outcomes of results from balloon angioplasty, the use of stents came into vogue which essentially was balloon angioplasty with introduction of an implant into the arterial area of narrowing that would prevent the renarrowing of the arterial segment (Sculpher et al., 2002).
The results of failure of angioplasty are many. The first important ones are unacceptable short and long-term clinical and angiographic outcomes. Next are the high rates of restenosis, high incidence of abrupt closure of the target vessels leading to life-threatening complications, and low incidence of target vessel revascularization, which happened to be the intended objective and indication of angioplasty as a procedure. Although there are numerous studies researching the implications of a failed angioplasty in the clinical scenario, despite having quite a number of studies, investigating the economic issues related to angioplasty as a procedure has been inadequate (Hannan et al., 1997).
A second procedure during the same hospital stay, a failed procedure needing another, associated morbidities of a failed procedure all have negative implications for the patient or the providers, although all these scenarios adds to ...Download file to see next pagesRead More

Nursing care during Primary Angioplasty

...?Nursing Care and Primary Angioplasty Vs. Thrombolysis The case of a 45 years old male who was brought to the hospital with severe central chest painis considered. ECG showed massive ST elevation in the antero-lateral leads. On arrival at the hospital, the patient’s signs and symptoms such as TPR (temperature, pulse and respiratory rate), blood pressure and blood glucose levels were recorded. Considering all the reports, he was advised to undergo emergency Primary Percutaneous Coronary Intervention (PPCI), also commonly known as Coronary Angioplasty, for left anterior descendent artery. Usually in such cases, as a first step once the patient is brought in, detailed history of the patient is taken by the...

Cardiovascular Disease

...treatment plan. Treatment options: The traditional approach is medication and surgery, but several published studies indicate that a second and even third opinion should be obtained before proceeding with surgery. There are three basic ways to treat atherosclerotic disease: medication, surgery, and minimally invasive interventional procedures such as stent implantation, percutaneous transluminal coronary angioplasty (PTCA), atherectomy, and excimer laser therapy. The purpose of these treatments is to eliminate or reduce the symptoms and, in the case of coronary artery disease, decrease the risk of heart attack. Medications can be used by themselves or in combination with one of the treatments. While medications do...

Nursing Assessment

...a single therapy (Bell, 1996). Nevertheless, most authors agree that clipping the aneurysm or using an endovascular intervention such as coiling, stenting, or angioplasty within 48 hours of the initial haemorrhage is imperative to minimize the occurrence of both vasospasm and rebleeding (Bell, 1996). Early surgical clot removal also limits the amount of oxyhemoglobin released, reducing the incidence of vasospasm (Bell, 1996) Recommendations include administration of calcium channel blockers and use of triple H therapy as these are both widely accepted interventions after clipping or coiling (Chiappetta, 1998). These measures were found to be most effective when used prophy-lactically (Rusy, 1996). But once vasospasm is...

...with weakened heart muscles. [2] Calcium channel blockers: These medications relax the smooth muscle layer that surrounds a coronary artery and cause the vessels to open, increasing blood flow to the heart they also control high blood pressure. [1] Invasive Procedures Percutaneous coronary interventions Angioplasty: This technique opens narrowed arteries. It is performed by interventional cardiologists. They use a long, thin tube called a catheter that has a small balloon on its tip. They inflate the balloon at the blockage site in the artery to flatten the plaque against the artery wall. Angioplasty is also called percutaneous transluminal coronary angioplasty (PTCA) [6] The procedure:...

...of the patient. In addition, the results of the results of the diagnostic tests also showed indications of the angina. In addition, the working diagnosis is based on the consideration of the pathogenesis of the different types of heart diseases such as the ischemic heart disease, myocardial infarction and even death (Yasue, Nakagawa, Itoh, Harada and Mizuno, 2008). Treatments and Interventions There are different types of treatments and interventions that can be used to respond to cases of coronary heart disease on the basis of the level and severity of the ailment. Medical procedures include angioplasty and CABG. Angioplasty is the process that leads to the opening of the arteries that had been...

Myocardial Infarction

...patients (Montalescot 2001). Yet, the specific effects and safety of antithrombin drugs and antiplatelet treatments are yet to be discovered (Boden & Mackay 2001). Despite the relative effectiveness of thrombolytic drugs, they can hardly compare to the benefits of coronary angioplasty. Angioplasty results in 95% improved vessel patency, compared with 80% improvements for thrombolytic drugs (Stone, Grines & O’Neill 1997). Unfortunately, only a few patients have a chance to use the benefits of angioplasty, as far as most hospitals that admit myocardial infarction patients do not have necessary interventional facilities (Gerschlick & More 1998). Angioplasty should serve a...

Heart attack

...that the heart muscle receives a continuous flow of oxygenated blood. The heart muscle requires a continuous nourishment of oxygenated blood in order to function. Lack of this results in the death of its muscle cells which brings about heart attack. This disorder is also referred to as a myocardial infarction as it results in a permanent death of the heart muscle. ‘Myo’ means muscle, ‘cardial’ is the heart while ‘infaction’ refers to the death of a tissue due to lack of blood supply. Recommendation of appropriate solutions A possible remedy for this disorder is angioplasty. This refers to a surgical unblocking or repair of the coronary artery. This surgical procedure is often done to open up blocked or narrow...

Potential sheath removal issues

...Potential Sheath Removal Issues Potential Sheath Removal Issues Introduction Angioplasty relates to a procedure done to improve blood flow in the arteries and veins. This procedure is minimally invasive. The procedure involves insertion of a balloon-tipped catheter into the blood vessel to the narrowed or blocked section where the balloon is then inflated to open the vessel. A bare stent or stent graft may be placed in the blood vessel to keep it open. They are usually placed and expanded inside the artery or vein to prop the walls open. Angioplasty and stenting are used to treat narrowing or blockage of arteries or veins in the body. The blockage may be attributable to conditions including atherosclerosis, coronary artery disease... or...

Grossman's Cardiac Catheterization, Angiography, and Intervention

...Post Angiogram done on a patient The patient (Popliteral Femoralie) had complications before he was admitted in the cardiac ward and got readmitted again. Readmission to the ward was after the failure of the radial angiogram followed by femoral angiogram that involved angioplasty. The stent was also placed in the left frontal descending artery of the patient. It shows that the post angiogram was to be carried out to the patient in order for the cardiologists to examine what was the problem. Popliteral was placed unique position such as lying on the table in order to promote appropriate inhalation. The cardiologists later started cardiac telemetry. Cardiac telemetry helps in diagnosing the yield of arrhythmia and manages...

...from acquiring sufficient oxygen. The other reasons why cardiogenic shock results include heart valve infection, heart muscle inflammation, weak heart, poisoning, and drug overdose (Lee Linda, Bates, Pitt, & Walton, 2010). Question 3: The coronary angioplasty process is realized when a catheter that is tipped in the form of a balloon is inserted to an artery in the arm or groin when enlarge a contracted coronary artery. This mostly occurs when cholesterol accumulates in the arteries’ that direct heart to the wall. With this process, it is possible for an individual to improve survival chances in the event of cardiogenic shock. This is because with the removal of the material accumulating in the arteries, the blood gets...
