Angioplasty

These advancements include an implantable cardioverter-defibrillator, an intra articular arthroscopic shaver system, and an angioplasty balloon catheter. The implantable cardioverter-defibrillator is a small generator powered by a battery and it works by sending electrical impulses when it detects cardiac arrhythmias. The implantable cardioverter-defibrillator was made in 1969, but was not used until 1980 by Levi Watkins Jr., M.D. at the John Hopkins Hospital. The intra articular arthroscopic shaver system includes “a rotating burr housed within a rigid insertion tube.” The shaver system removes tissue and cartilage from patient’s joints and was an “essential development for minimally invasive orthopedic surgery.” The intra articular arthroscopic shaver system is used by orthopedic surgeons during arthroscopic surgeries. An angioplasty balloon catheter uses an inflatable balloon on a double-lumen catheter and it works to repair blocked vessels; however, this device has many risks to consider. A major risk is the chance of developing restenosis. The angioplasty balloon catheter was made in the 1970s by Andreas Gruentzig, but was not used until 1980 (Mddi Admin). Surgeries that happened for the first time in this decade were an open fetal operation and the first robot-assisted surgery. The first fetal operation was performed…

here is the most recent of nine studies comparing angioplasty and bypass surgery in a scientifically rigorous way. They all produced similar results. But patients facing a choice between the two procedures need to consider more than recovery time and the prospect of a return trip to the hospital. When weighing the two options, the most important thing to ponder in light of all these comparative studies is whether the study results apply to you. These studies calculate average outcomes over…

Primary Angioplasty – A Life-saving Procedure Primary angioplasty is a term used to describe an angioplasty done as a life-saving emergency procedure in a patient with an on-going heart attack [PAMI - Primary Angioplasty in acute Myocardial Infarction]. The international accepted door to balloon time intervention is within 90 minutes and 3 to 6 hours from the onset of heart attack for PAMI. Doing angioplasty in a critical patient of heart attack is in itself challenging and doing so in the…

CORONARY STENTS Before stents were used, balloon angioplasty was used to treat narrowed coronary arteries. This involved inserting a very thin, long, balloon-tipped tube into an artery where there was a blockage. The balloon at the tip of the catheter was inflated to compress the blockage and restore blood flow. It was then deflated to remove the catheter and balloon but because no support was left at the site of the blockage, in some cases, the artery collapsed. This is why small stents were…

Coronary angioplasty is a medical procedure which opens up blocked blood vessels thereby restoring blood flow to the heart muscle.38 Angioplasty procedures take place at the area of thigh or the arm which is shaved to prevent the bacterial infection. The area is then cleaned with the special antibacterial agent and covered with sterile drapes to prevent infection. A numbing medication, local anesthetic drug lidocaine is injected into the skin over the blood vessel of the thigh or an arm, keeping…

Demonstrate the role of stents in Percutaneous Coronary Intervention (coronary angioplasty) Introduction The heart is a pump that circulates blood to the rest of the human body. It is positioned at the centre of the chest, just between the lungs. The network of blood vessels that branch over the surface of the heart are the coronary arteries. Figure 1 outlines the coronary arteries on the heart which supply the cardiac muscles with nutrients such as oxygen and glucose needed to survive [1].…

Introduction The client is MK, a 50 year old female who is status post 3 hours of a percutaneous transluminal coronary angioplasty (PTCA). The PTCA was performed because MK failed a cardiac stress test and was found to have significant coronary disease with a 90% blocked mid-left anterior descending artery and a 90% blocked proximal circumflex artery, which required the placement of two stents. MK is currently employed as a daycare owner, and she is married, but the couple does not have children…

It is a procedure in which a balloon catheter is inserted into vessels that have been damaged due to atherosclerosis, or build up of plaque and cholesterol in a certain part of a vessel, causing it to be narrower than normal. Atherosclerosis has to be treated immediately because it elevates blood pressure and prevents proper circulation of blood to all parts of the body. Specifically angioplasty can be divided into percutaneous coronary intervention, peripheral angioplasty, and renal artery…

delay the advancement of atherosclerosis in their arteries.12:All 2. Angioplasty- Patients with severe atherosclerosis have an artery that has a greater than 70% reduction in diameter due to cholesterol buildup. The mission of the procedure is to increase the amount of space available for blood flow in a mostly blocked artery. The surgeon will insert a balloon to open up the space and then insert a stent to ensure the artery stays open.12:All 3. Coronary Artery Bypass Grafting- This treatment…

From the case, the total number of angioplasty patients is 700,000 patients. Since Medicines Company only investigates 92% of all angioplasty procedures, we need to multiply by 0.92. And since Angiomax will be positioned to be used by high and very high risk patients we must also take that into account. From the case, we know on average 50% of angioplasty patients are considered “high risk” and 10% are considered “very-high risk .” Therefore Angiomax has the possibility to affect 60% of all…
