Interventional- Coronary Angiography with multi slice computed tomography
Conventional X-ray coronary angiography is a method for the assessment of coronary
Vessel disease. It is an invasive and high risky procedure including a small risk of coro nary events such as arrhythmia, stroke, coronary artery dissection and death. Fur thermore, the coronary catheterisation procedure involves the risk of internal bleed ing,dissections,post procedural events during hospitalisation and discomfort to the patient. Multi-slice Coronary Computed Tomography (MSCCT) scanners are widely avail able diagnostic options in the field of intervention. These scanners are widely accepted by the technicians by helping them to follow the non-invasive coronary angiography

The new generation of CT scanners(Multi detecter) can operate in an increased ro tation rate and can produce up to four slices simultaneously. Partial scan-reconstruction techniques, which apply a 90180 reconstruction algorithm, improve the temporal res olution to 250 ms. These recent developments in the field of intervention allow high

Calcification Detection in Coronary Arteries using Image Processing speed scanning of large volumes with a high in-plane resolution, as well as an im proved Z-axis resolution with a substantial improvement in the inter-slice correlation and these algorithms reduce the effective slice thickness at an acceptable increase in noise and reduction in contrast [5]. The modifications in the reconstruction software have further reduced the virtual temporal resolution at Tachy Cardia by combining the data from several heart slices in one image, shortening the effective acquisition intervals to 125 ms. The in-plane spatial resolution of the MSCCT scanner is nine line pairs per cm.It used retrospective gating, which allows post-scan acquisition window selection and optimum result.This approach improves the image quality and decreases the sensitivity to arrhythmia and ECG
Angioplasty opens blocked arteries and restores normal blood flow to your heart muscle. It is not major surgery. It is done by threading a catheter (thin tube) through a small puncture in a leg or arm artery to the heart. The doctor threads the catheter through the arterial system until it gets into a coronary (heart) artery. The blocked artery is opened by inflating a tiny balloon on the end of the catheter. The doctor inflates the balloon to push the plaque outward against the wall of the artery. This widens the artery by stretching it and restores blood flow.
Hi, my name is LeAna. I am a student at Midlands Technical College hoping to someday be a professional in the field of cardiovascular technology. Because of my interest in cardiac imaging, I have decided to do some research on the Society of Invasive Cardiovascular Professionals, SICP. This professional organization works provide professionals in the cardiovascular health care field with educational opportunities for invasive specialist, high quality care for patients, and support for invasive cardiovascular leaders. Someday in the near future, I will be one of the healthcare professionals in the cardiovascular field. In this essay, I will discuss SICP’s purpose, design, interactivity, and its influence.
A 3D-TOF method would almost certainly be initially performed although its long imaging time (around 5 minutes) makes it susceptible to movement artefacts, requiring patient compliance (Burgess & Kidwell, 2010). 3D-TOF sequences can show reduced flow signal in areas of tortuous or stenotic vascular segments, or when a vessel runs in-plane with the imaging slab potentially causing exaggeration of stenoses and misdiagnosis (Essig & Tanenbaum,
This paper describes in detail considering one of the possible post- procedural complications of Mrs. Elizabeth Green, who has undergone the coronary angioplasty procedure to relieve chest pain caused due to blood vessel occlusion. Mrs. Green, a 78-year-old Caucasian woman, lives independently at home with her pet dog. She has a son and daughter, who occasionally visit her and provide some support (School of Nursing & Midwifery 2014). ). Mrs Green has a past medical history of gastro oesophageal reflux disease, hypertension, hypercholesterolemia, osteoarthritis and diet controlled type two diabetes mellitus (School of Nursing & Midwifery 2014). There are certain complication arises as a result of the procedure
Some lifestyle-related conditions and decisions increase the likelihood of a person having heart disease. Some examples are diabetes, overweight and obesity, poor diet, lack of physical activity and excessive consumption of alcohol. High blood pressure, low-density lipoprotein (BAD) cholesterol, and smoking are key risk factors for heart disease. LBD is considered to be "bad" cholesterol because having high levels can lead to accumulation in the arteries, which can cause heart disease and stroke. If you lower your blood pressure and cholesterol, and if you do not smoke, you will reduce your chances of having heart disease. Now, in case of emergency, angioplasty which is the best treatment needs to get done. In this case we need to kake in consideration that not all hospitals are capable to made the process, so we need to be aware of our options. After the angioplasty you should take a daily medication, which will help your heart adapt to the implanted stents and they will not close again, a phenomenon known as restenosis, his medication should not be forgotten any day in order to minimize future
Thank you for your post Rhea. You have identified key takeaways for emerging benefits and limitations of the three imaging modalities for diagnosing PAD. I would like to reverberate your thoughts on the disease process for emphasis. Patients with notable symptoms of peripheral arterial disease (PAD) with affectation of lower extremities are primarily assessed with an ankle-brachial index and segmental pressure measurements (Pollak, Norton, & Kramer, 2012). Classification of PAD can be accomplished with noninvasive angiography utilizing computed tomography (CTA) or magnetic resonance angiography (MRA), as well as with duplex ultrasonography (US) depending on patient’s specific needs and limitations (Pollak, Norton, & Kramer). In my further
Interventional radiologists treat and diagnose disease using imaging equipment. Interventional radiologists sometimes sub-specialise further so that they only treat abnormalities of the brain or spinal cord (neuro intervention) or of the blood vessels other places in the body (angiointervention). Interventional radiology is a minimally invasive procedures using X-ray, magnetic or ultrasound images to help guide the procedures, mainly done with small instruments and very thin plastic tubes called catheters inserted through an artery or vein.
Primary percutaneous coronary intervention (PCI) and PCI with fibrinolysis are current therapy options used for patients who have had an acute ST elevation myocardial infarction (STEMI). These six article discuss multiple elements involved in the discussion comparing the many factors that affect which forms of therapy is preferred to which patients. Concerns regarding the safety and effectiveness of primary PCI have risen. Factors include the optimal time for therapy, the important of hospital staff and volume, and the efficiency of PCI after fibrinolysis.
The purpose of the coronary artery bypass study was to analyze women’s experiences with surgery. Possible participants were chosen from a cardiac waiting list at two teaching hospitals in England and Wales between 2003 and 2006. The eligible criteria included, women who could read and understand English, and were eighteen years or older first-time coronary artery bypass graft surgery patients. Thirty Caucasian women were chosen to conduct the study over. Due to a lack in a diverse population, the study cannot be evidence for all women.
Acute coronary syndrome (ACS) refers to a spectrum of clinical presentations ranging from those for ST-segment elevation myocardial infarction (STEMI) to presentations found in non- ST-segment elevation myocardial infarction (NSTEMI) or in unstable angina. It is almost always associated with rupture of an atherosclerotic plaque and partial or complete thrombosis of the infarct-related artery; those two types of acute coronary syndrome are in regarding ECG changes.
There are many new technologies and advancements within the cardiovascular community. These technologies and advancements happen frequently and are to help better the equipment for better outcomes for patients treated. One of the new technologies that has made great strides is the orbital atherectomy. Orbital atherectomy is a technology created by a company called Cardiovascular Systems Inc. (CSI). What the new device does is make it easier and safer for balloon and stent administration within a heavily calcified vessel. The ORBIT is a new instrument used during a catheterization procedure that can break up calcified plaque. Patients that have a clogged coronary artery, that is restricting the blood flow to the heart would benefit from the
Angina pectoris is a clinical syndrome when the heart does not get enough oxygen from blood and can lead to ischemia.22 Angina is classified into three classes: stable, unstable, and printzmetal/variant.4,16,20
arteries totally blocked181. Damage is reversible for approximately 20-30 minutes after complete obstruction of blood flow; thereafter myocardial cell death ensues and progresses as time passes182-184. Therefore, complete and sustained restoration of blood flow must be as prompt as possible to ensure maximum salvage of functional myocardium, a principle expressed in the maxim “time is muscle”185. This is achieved with reperfusion therapy, which is based on invasive reopening of the afflicted coronary artery with primary PCI, or non-invasive breaking up of the responsible blood clot with a thrombolytic drug186. Patients without ST-elevation are said to suffer from NSTEMI and tend not to have full occlusion of a coronary artery187. If there is evidence of myocardial cell death they are considered to have a NSTEMI; otherwise they are classified as suffering from unstable angina188. Their management is based on the estimation of their risk for adverse events. Patients at low risk can be adequately treated with medical therapy, in many ways similar to the one used for STEMI189-190. Those at moderate to high-risk benefit from an early invasive strategy, which includes coronary angiography, and if necessary, revascularization with
CAAs finding has significantly increased after coronary angiography diffusion since previous studies were conducted only postmortem [2, 29]. The technological improvements of computed tomography have declared it as a powerful tool for coronary diseases detection such as CAAs. An appropriate imaging assessment should provide a correct identification of aneurysms, in particular number, location, shape, size, intraluminal thrombi, occlusions and associated stenoses [17]. Kanamaru and colleagues [22] demonstrated that CTCA has a 100% sensitivity in CAAs detection; a 87.5% sensitivity and a 92.5% specificity were found for significant coronary artery stenoses and occlusions detection. To date, no data are available about CAAs evaluated by CTCA from
Kevin has two blocked coronary arteries which means he has coronary artery disease and the best procedure to fix this would be to have coronary artery bypass surgery. He also has metabolic syndrome. First, he has high blood pressure of 145/90, second, his cholesterol levels are high - at a range of 155 mg/dL LDL and 38 mg/dL HDL, third he has high triglyceride level of 165 mg/dL, and last but not least he is overweight.
