Functional Coronary Angiography Ischemia with No Obstructive Coronary Artery disease (INOCA) refers to patients with signs and symptoms (chest pain, chest tightness, neck/shoulder/arm/back pain, shortness of breath, fatigue or other related symptoms) caused by blood supply problems to the heart muscle without significant blockage of the large arteries of the heart. INOCA is more common in women but also affects men. Many patients with INOCA have coronary microvascular disease, which is a disease of the small arteries of the heart. Functional coronary angiography (FCA) also referred to as coronary reactivity test (CRT) is an angiography procedure done in the catheterization laboratory. It evaluates the coronary artery microcirculation and how the blood vessels respond to different medications. Cardiologists use this information to diagnose coronary microvascular disease. The results of this test enhance a cardiologist’s ability to diagnose and treat patients with coronary microvascular disease or vasospastic disease and provide more specific treatment for symptoms of patients with INOCA. FCA/CRT test consists of: 1. Administration of the drug adenosine, which normally causes the small vessels of the heart to dilate, is injected into one of the coronary arteries and the amount of blood flow is measured. 2. Next, the drug acetylcholine, which normally causes dilation in the large arteries, is injected and the amount of blood flow is again measured. 3. Next, the drug nitroglycerin If any of the tests show decreased blood flow to the heart muscle, a diagnosis of endothelial dysfunction and coronary microvascular dysfunction can be made.

Equilibrium Radionuclide Angiography/ Multigated Acquisition
EQUILIBRIUM RADIONUCLIDE ANGIOGRAPHY/ MULTIGATED ACQUISITION Equilibrium Radionuclide Angiography/ Multigated Acquisition S van Eeckhoudt, Bravis ziekenhuis, Roosendaal VJR Schelfhout, Rijnstate, Arnhem 1. Introduction Equilibrium radionuclide angiography (ERNA), also known as radionuclide ventriculography (ERNV), gated synchronized angiography (GSA), blood pool scintigraphy or multi gated acquisition (MUGA), is a well-validated technique to accurately determine cardiac function. In oncology its high reproducibility and low inter observer variability allow for surveillance of cardiac function in patients receiving potentially cardiotoxic anti-cancer treatment. In cardiology it is mostly used for diagnosis and prognosis of patients with heart failure and other heart diseases. 2. Methodology This guideline is based on available scientifi c literature on the subject, the previous guideline (Aanbevelingen Nucleaire Geneeskunde 2007), international guidelines from EANM and/or SNMMI if available and applicable to the Dutch situation. 3. Indications Several Class I (conditions for which there is evidence and/or general agreement that a given procedure or treatment is useful and effective) indications exist: • Evaluation of left ventricular function in cardiac disease: - Coronary artery disease - Valvular heart disease - Congenital heart disease - Congestive heart failure • Evaluation of left ventricular function in non-cardiac disease: - Monitoring potential cardiotoxic side effects of (chemo)therapy - Pre-operative risk stratifi cation in high risk surgery • Evaluation of right ventricular function: - Congenital heart disease - Mitral valve insuffi ciency - Heart-lung transplantation 4. Contraindications None 5.

Downloaded from Br Heart J 1984; 51: 36-45 Comparison of echocardiography and angiography in determining the cause of severe aortic regurgitation NICHOLAS L DEPACE, PASQUALE F NESTICO, MORRIS N KOTLER, GARY S MINTZ, DEMETRIOS KIMBIRIS, INDER P GOEL, E ELAINE GLAZIER-LASKEY, JOHN ROSS From the LikoffCardiovascular Institute, Hahnemann University, Philadelphia, Pennsylvania, USA SUMMARY To assess the accuracy of echocardiography in determining the cause of aortic regurgita- tion M mode and cross sectional echocardiography were compared with angiography in 43 patients with predominant aortic regurgitation. Each patient had all three investigations performed during the same admission to hospital. In each instance, the cause of aortic regurgitation was confirmed at surgery or necropsy. Seventeen patients had rheumatic aortic valve disease, 13 bacterial endocarditis with a perforated or partially destroyed cusp, five a biscuspid aortic valve (four with a history of endocarditis), and eight aortic regurgitation secondary to aortic root dilatation or aneurysm. Overall sensitivity of echocardiography and aortography was 84% in determining the cause of aortic regurgi- tation. Thus, rheumatic valve disease and endocarditis appear to be the most common causes of severe aortic regurgitation in this hospital based population. Furthermore, echocardiography is a sensitive non-invasive technique for determining the cause of aortic regurgitation and allows differentiation of valvular from root causes of aortic regurgitation. Aortic regurgitation may be caused by valvular dis- ment for predominant aortic regurgitation were http://heart.bmj.com/ ease, aortic root disease, or a combination of both. reviewed.

Downloaded from Measurement of peak rates of left ventricular wall movement in man Comparison of echocardiography with angiography D. G. Gibson and D. J. Brown From the Cardiac Department, Brompton Hospital, London, and the Medical Computer Centre, Westminster Hospital, London Estimates ofpeak systolic and diastolic rates of left ventricular wall movement were made in 23 patients by echocardiography and angiocardiography. Echocardiographic measurements were calculated as the rate of change of the transverse left ventricular dimension, derived continuously throughout the cardiac cycle. These were compared with similar plots of transverse left ventricular diameter, in the same patients, derived from digitized cineangiograms taken within IO minutes of echocardiograms. The results indicate close correlation between the two methods, and suggest that either can be used to measure peak rates of left ventricular wall movements in patients with heart disease.

IVUS of the coronary arteries (consistent with the 2011 ACCF/AHA Guidelines for Percutaneous Coronary Intervention (PCI) 5.4.2) is indicated for any of the following medical reasons: a. To confirm clinical suspicion of a significant left main coronary artery stenosis when standard angiography is indeterminate; b. To detect rapidly progressive cardiac allograft vasculopathy following heart transplant; c. To determine the mechanism of stent thrombosis or restenosis; d. To assess non-left main coronary arteries with angiographic intermediate stenosis (50-70%) to aid the decision whether or not to place a stent; or, e. To assist in guidance of complex coronary stent implementation, especially involving the L main coronary artery. 2. In lieu of coronary angiography when performed to minimize use of iodinated contrast material in an individual with compromised renal function, congestive heart failure or known contrast allergy. Limitations Coronary IVUS is not covered for any of the following (this is not an all-inclusive list): 1. Screening for coronary artery disease in asymptomatic individuals; 2. Routine lesion assessment is not recommended when revascularization with PCI or Coronary Artery Bypass Grafting (CABG) is not being considered; 3. Carotid stent placement; 4. Follow-up monitoring of medical therapies for atherosclerosis; 5. Peripheral vascular intervention; or, 6. Evaluation of chronic venous obstruction or to guide venous stenting.

A Practical Guide to Virtual Autopsy: Why, When And
A Practical Guide to Virtual Autopsy: Why, When and How Laura Filograna, MD, PhD,* Luca Pugliese, MD,* Massimo Muto, MD,* Doriana Tatulli, MD,* Giuseppe Guglielmi, MD,† Michael John Thali, MD,z and Roberto Floris, MD, PhD* Postmortem imaging is considered a routine investigative modality in many forensic institu- tions worldwide. Because of its ability to provide a quick and complete documentation of skeletal system and major parenchymal alterations, postmortem computed tomography (PMCT) is the imaging technique most frequently applied in postmortem forensic investiga- tions. Also postmortem magnetic resonance has been implemented in postmortem setting, but its use is mostly limited to focused analysis (eg, study of the heart and brain). PMCT presents some limits in investigating “natural” deaths, particularly related to its poor ability in differentiating soft tissue interfaces and in depicting vascular lesions. For this reason, PMCT angiography has been introduced. A major limitation of these postmortem imaging techniques is the absence of body samples for histopathologic, toxicologic, or microbiolog- ical analysis. This limit has been overcome by the introduction of postmortem percutaneous biopsies. The aim of this review is to provide a practical guide for virtual autopsy, with the intent of facilitating standardization and augmenting its quality. In particular, the indications of virtual autopsy as well protocols in PMCT examinations and its ancillary techniques will be discussed. Finally, the workﬂow of a typical virtual autopsy and its main steps will be described. Semin Ultrasound CT MRI 40:56-66 © 2018 Elsevier Inc. All rights reserved.

Development of the ICD-10 Procedure Coding System (ICD-10-PCS)
Development of the ICD-10 Procedure Coding System (ICD-10-PCS) Richard F. Averill, M.S., Robert L. Mullin, M.D., Barbara A. Steinbeck, RHIT, Norbert I. Goldfield, M.D, Thelma M. Grant, RHIA, Rhonda R. Butler, CCS, CCS-P The International Classification of Diseases 10th Revision Procedure Coding System (ICD-10-PCS) has been developed as a replacement for Volume 3 of the International Classification of Diseases 9th Revision (ICD-9-CM). The development of ICD-10-PCS was funded by the U.S. Centers for Medicare and Medicaid Services (CMS).1 ICD-10- PCS has a multiaxial seven character alphanumeric code structure that provides a unique code for all substantially different procedures, and allows new procedures to be easily incorporated as new codes. ICD10-PCS was under development for over five years. The initial draft was formally tested and evaluated by an independent contractor; the final version was released in the Spring of 1998, with annual updates since the final release. The design, development and testing of ICD-10-PCS are discussed. Introduction Volume 3 of the International Classification of Diseases 9th Revision Clinical Modification (ICD-9-CM) has been used in the U.S. for the reporting of inpatient pro- cedures since 1979. The structure of Volume 3 of ICD-9-CM has not allowed new procedures associated with rapidly changing technology to be effectively incorporated as new codes. As a result, in 1992 the U.S. Centers for Medicare and Medicaid Services (CMS) funded a project to design a replacement for Volume 3 of ICD-9-CM.

Cardiac Catheterization and Angiogram ______
Cardiac Catheterization and Angiogram __________________________________________ A cardiac catheterization is a procedure that allows the cardiologist to get direct information about the blood pressures and patterns of blood flow within your heart. An angiogram is an X- ray movie that’s taken while special fluid (called contrast) that’s visible by X-ray is injected into a cardiac chamber or major blood vessel. Your cardiologist or nurse will explain the reason for this procedure and how it will help in your care. They will also explain the test’s possible risks, which fortunately are rare. After you’ve heard about the test and have had a chance to ask questions, you’ll be asked to sign a consent form to have the test. Since a catheterization and angiogram require special X-ray equipment that’s only found in hospitals or large medical facilities, the test must usually be scheduled in advance. Patients may be admitted to the hospital on the day of the catheterization or the day before. For several hours before the catheterization, you’ll be told not to eat or drink anything. Before the test is done, you may be given a sleeping medicine by mouth or in a small shot under the skin. An intravenous line (IV) is sometimes placed in one of the veins. During the catheterization you’ll be cared for by a team of nurses, doctors and technicians. The catheterization test usually causes little discomfort. The catheterization involves placing small IV tubes in the vein and artery of a leg, arm or the neck. Through the special IV tubes the cardiologist can pass thinner tubes (called catheters) into the circulation.
