The Importance Of Ultrasound In Cardiology

Pages 8
The role of interventional radiology has played a significant part in the diagnosis and treatment of patients. There have been many advances with instrumentation, and equipment, promoting excellent care to patients in the cardiac catheterization laboratory. Ultrasound has been an exceptional tool in assisting physicians with selection of coronary balloons, and stents for percutaneous coronary interventions. As a critical piece of data collection, ultrasound measurements have emerged as a frontrunner in evaluating vessel diameter and intra-lumen irregularities. This measurement and visualization has become paramount in the cardiac arena, when choosing proper sizing for stent selection. The influence of ultrasound in cardiology has shown …show more content…
What constitutes the terminology? PCI is a medical terminology which defines managing the occlusion of a coronary artery by means of balloons, stent, atherectomy or laser to open and reestablish blood flow to the heart (Farlex). What is the difference between POBA verses stents? Plain Old Balloon Angioplasty(POBA) is one of the first acronyms used in cardiac cath-labs to describe intervention of an artery. During the early 70’s there were really no cardiac stents, biliary stents were cut and crimped onto coronary balloons and implanted directly into the intima of a vessel wall. Often- times these were used off label, and quite dangerous due to bulkiness and fear of losing the stent in patient. But in the mid 80’s, the advent and creation of coronary stents were marketed using smaller profile balloons, where the stents were mounted and heat sealed to ensure safe deployment. As stents began to grow in popularity, there were assorted designs from various vendors claiming to have the best in radial strength, strut thickness and side wall …show more content…
What is IVUS? IVUS is an acronym for Intravascular Ultrasound, it is commonly used to measure blood vessels and correct proper selection of coronary stents during angioplasty. (NIH, 2018) This ultrasound wand is attached to a thin catheter, this catheter is inserted into an artery, imaging the lumen of the vessel. At first glance IVUS looks like a bad weather map, but it’s information is invaluable to the cardiologist, displaying luminal irregularities, intimal dissections and the formation of cholesterol build up and calcified plaque. The healthcare provider gets to look at your arteries from the inside out. It is like looking down the middle of a straw, all you see is a round circle. Looking at the intima of a blood vessel resembles walking on the surface of the moon. On the inner surface of a vessel there are craters of deposits, surrounded by peaks of calcium debris. The IVUS allow the clinician to visualize the lumen of the vessel, and properly choose the correct diameter of the circular structure. IVUS has helped clinicians see how stents become clogged with debris, or fatty deposits. These fatty deposits aid to the beginning of stent restenosis. One of the special features IVUS offers is color flow. Color flow allows the clinician to visualize venous and

BSN III-C Submitted to: Mrs. Miraluna Echavez, RN, MN March 2013 UTERINE LEIOMYOMA/ UTERINE FIBROIDS Uterine fibroids are noncancerous growths of the uterus that often appear during your childbearing years. Also called fibromyomas, leiomyomas or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer. As many as 3 out of 4 women have uterine fibroids sometime during their lives, but most are unaware of them because they often cause no symptoms. Your doctor may discover fibroids incidentally during a pelvic exam or prenatal ultrasound. In general, uterine fibroids seldom require treatment. Medical therapy and surgical procedures can shrink or remove fibroids if you have discomfort or troublesome symptoms. Rarely, fibroids can require emergency treatment if they cause sudden, sharp pelvic pain or profuse menstrual bleeding. Symptoms In women who have symptoms, the most common symptoms of uterine fibroids include: * Heavy menstrual bleeding * Prolonged menstrual periods — seven days or more of menstrual bleeding * Pelvic pressure or pain * Frequent urination * Difficulty emptying your bladder * Constipation * Backache or leg pains Rarely, a fibroid can cause acute pain when it outgrows its blood supply.

Robotic surgery is an emerging technology that began its experimental phase in 1985 with the introduction of the PUMA 560 robotic arm. The first use of a robot for a surgical procedure was a neurosurgical biopsy, recorded in 1985. Following this successful surgery was the first laparoscopic surgery using the same kind of robot; the robotic arm. In 1987, a successful cholecystectomy was performed. In 1988, doctors decided to use the PUMA 560 robotic arm for a transurethral resection procedure. Finally, in 1990, the Automated Endoscopic System for Optimal Positioning (AESOP) became known as the first system to be approved by the Food and...

Ben Kibler TENNIS RECOVERY A Comprehensive Review of the Research A United States Tennis Association Sport Science Committee Project Editors: Mark S. Kovacs, PhD Todd S. Ellenbecker, DPT W. Ben Kibler, MD Introduction In the last two decades, physical training and competitive opportunities have increased dramatically in junior, collegiate and professional tennis. This arose due to a multitude of factors, but much of it has stemmed from an increase in knowledge and understanding of scientifically based training programs focused on improving performance. As this focus on performance has increased, the area of recovery has received relatively limited focus. Recovery is a multi-faceted paradigm focusing on recovery from training—session to session, day to day and week to week. Recovery is also vitally important during training as well as in competition between matches and between days during multi-day tournaments. As more information is needed in the area of tennis specific recovery, the Sport Science Committee of the United States Tennis Association (USTA) sponsored an extensive evidence-based...
