Coronavirus The normal heart lies within the pericardial sac in the middle of the thorax slightly to the left of the middle (Sokolow 1979). The low pressure right atrium and right ventricle occupy the anterior portion of the heart and the higher pressure left ventricle and atrium his posteriorly (Sokolow 1977). The long axis of the heart from the apex of the left ventricle to the root of the aorta runs upwards and backward at an angle of about 300 from the horizontal plane and 450 from the sagital plane of the body (Sokolow 1977). The resisting and position of the heart vary with the build of the patient and with respiration. It assumes a more vertical position during inspiration in tall thin persons and more horizontal position during respiration in persons with heavier body build. (Sokolow1977).

  1. LVRS is used widely in Europe, though its application in the United States is mostly experimental.[29]
  2. A prolonged air leak (PAL) can occur in 8-25% of people following lung cancer surgery.[35][36] This complication delays chest tube removal and is associated with an increased length of hospital stay following a lung resection (lung cancer surgery).[37][38] The use of surgical sealants may reduce the incidence of prolonged air leaks, however, this intervention alone has not been shown to results in a decreased length of hospital stay following lung cancer surgery.[39]
  3. The patent foramen Ovale remain open or potentially open in about 15% of normal subjects (Malcolm 1977) but since it is a flap value which only allows flow right or left, it is normally functionally closed (Malcolm 1977).

I recommend that any research on cardiothoracic ratio is best with chest radiographs. Females should always keep good hygiene because of their susceptibility to infections because of their large cardiothoracic ratio.            3. Evaluate the distribution of flow from central to peripheral Lung volume reduction surgery, or LVRS, can improve the quality of life for certain COPD and emphysema patients. Parts of the lung that are particularly damaged by emphysema are removed, allowing the remaining, relatively good lung to expand and work more efficiently. The beneficial effects are correlated with the achieved reduction in residual volume.[25] Conventional LVRS involves resection of the most severely affected areas of emphysematous, non-bullous lung (aim is for 20-30%). This is a surgical option involving a mini-thoracotomy for patients suffering end stage COPD due to underlying emphysema, and can improve lung elastic recoil as well as diaphragmatic function.

  7. Sometimes the heart can be smaller than 50% of the cardiothoracic ratio but still be an abnormal heart. This occurs when there is something obstructing the flow of blood from the ventricles since the ventricles respond at first by undergoing hypertrophy, which does not produce cardiomegaly.                         

In 1947 Thomas Holmes Sellors (1902–1987) of the Middlesex Hospital operated on a Fallot's Tetralogy patient with pulmonary stenosis and successfully divided the stenosed pulmonary valve. In 1948, Russell Brock, probably unaware of Sellor's work, used a specially designed dilator in three cases of pulmonary stenosis. Later in 1948 he designed a punch to resect the infundibular muscle stenosis which is often associated with Fallot's Tetralogy. Many thousands of these "blind" operations were performed until the introduction of heart bypass made direct surgery on valves possible.[10] Precision - Precision is the ratio of correctly predicted positive observations to the total predicted positive observations.

  4. Dilation of the azygos vein is a sign of increased right atrial pressure and is usually seen when there is also an increase in the width of the vascular pedicle. The diameter of the azygos vein varies according to the positioning. In the standing position a diameter > 7 mm is most likely abnormal and a diameter > 10 mm is definitely abnormal. In a supine patient > 15 mm is abnormal. An increase of 3 mm in comparison to previous films is suggestive of fluid overload. The difference of the azygos diameter on an inspiration film compared to an expiration film is only 1mm. This means that the diameter of the azygos is a valuable tool whether or not there is good inspiration.

Often times, when this ratio is larger than 0.50 -- this is a sign your heart is larger than normal. This could be a result of high blood pressure causing enlargement of the heart -- called hypertroph The American Board of Thoracic Surgery offers a special pathway certificate in congenital heart surgery which typically requires an additional year of fellowship. This formal certificate is unique because pediatric cardiac surgeons in other countries do not have formal evaluation and recognition of pediatric training by a licensing body. A heart can be greater than 50% of the cardiothoracic ratio and still be a normal heart (Herring, 2003). This can occur  if there is an ultra cardiac cause of cardiac enlargement which include;

Early approaches to heart malformationsedit

Congestive heart failure (CHF) is the result of insufficient output because of cardiac failure, high resistance in the circulation or fluid overload. Left ventricle (LV) failure is the most common and results in decreased cardiac output and increased pulmonary venous pressure. In the lungs LV failure will lead to dilatation of pulmonary vessels, leakage of fluid into the interstitium and the pleural space and finally into the alveoli resulting in pulmonary edema. In 1919, Danzer undertook one of the earliest studies of the cardiothoracic ratio. After investigation nearly 500 patients without the aid of hemodynamic parameters, He determined that any measurement over 0.5 or 50% was suspicious and over 0.52or 52% was definitely pathological.            VSD                                        Left atrium not always enlarged

Open heart surgery is a procedure in which the patient's heart is opened and surgery is performed on the internal structures of the heart. It was discovered by Wilfred G. Bigelow of the University of Toronto that the repair of intracardiac pathologies was better done with a bloodless and motionless environment, which means that the heart should be stopped and drained of blood. The first successful intracardiac correction of a congenital heart defect using hypothermia was performed by C. Walton Lillehei and F. John Lewis at the University of Minnesota on September 2, 1952. The following year, Soviet surgeon Aleksandr Aleksandrovich Vishnevskiy conducted the first cardiac surgery under local anesthesia. The cardiothoracic ratio (CTR) derived from CR is traditionally used to estimate LV size (11,12) and is associated with LV systolic dysfunction (13,14). A high CTR, estimated by CR, is a marker of.. Cardiac surgery changed significantly after World War II. In 1948 four surgeons carried out successful operations for mitral stenosis resulting from rheumatic fever. Horace Smithy (1914–1948) of Charlotte, revived an operation due to Dr Dwight Harken of the Peter Bent Brigham Hospital using a punch to remove a portion of the mitral valve. Charles Bailey (1910–1993) at the Hahnemann Hospital, Philadelphia, Dwight Harken in Boston and Russell Brock at Guy's Hospital all adopted Souttar's method. All these men started work independently of each other, within a few months. This time Souttar's technique was widely adopted although there were modifications.[10][11]

Open heart surgeryedit

The knob will be greater than 35 mm due to increased pressure, flow, or changes in the elasticity of the wall e.g. cystic medial necrosis, ASCVD, dissection of the aorta. In normal people the aortic knob measures less than 35mm when measured from the lateral border of the trachea to the lateral border of the aortic knob. Cardiac surgery training in the United States is combined with general thoracic surgery and called cardiothoracic surgery or thoracic surgery. A cardiothoracic surgeon in the U.S. is a physician (M.D. or D.O.) who first completes a general surgery residency (typically 5–7 years), followed by a cardiothoracic surgery fellowship (typically 2–3 years). The cardiothoracic surgery fellowship typically spans two or three years, but certification is based on the number of surgeries performed as the operating surgeon, not the time spent in the program, in addition to passing rigorous board certification tests. Recently, however, options for an integrated 6-year cardiothoracic residency (in place of the general surgery residency plus cardiothoracic residency) have been established at many programs (over 20).[2] Applicants match into these I-6 programs directly out of medical school, and the application process has been extremely competitive for these positions as there were approximately 160 applicants for 10 spots in the U.S. in 2010. As of May 2013, there are now 20 approved programs, which include the following: This can occur if there is an extracardiac cause of cardiac enlargement. Extracardiac causes of cardiac enlargement include:             Inability to take a deep breath because of Before we do that, it is important to know that the pulmonary vasculature will fall into one of the following four categories:

Stage II of CHF is characterized by fluid leakage into the interlobular and peribronchial interstitium as a result of the increased pressure in the capillaries. When fluid leaks into the peripheral interlobular septa it is seen as Kerley B or septal lines. Kerley-B lines are seen as peripheral short 1-2 cm horizontal lines near the costophrenic angles. These lines run perpendicular to the pleura.            Cardiomyopathy            Normal aorta

The National Emphysema Treatment Trial was a large multicentre study (N = 1218) comparing LVRS with non-surgical treatment. Results suggested that there was no overall survival advantage in the LVRS group, except for mainly upper-lobe emphysema + poor exercise capacity, and significant improvements were seen in exercise capacity in the LVRS group.[26] The higher cardiothoracic ratio in females may suggest the reason of their susceptibility to infections arising from the heart and this could be correlated to clinical data. Stage III - Alveolar edema This stage is characterized by continued fluid leakage into the interstitium, which cannot be compensated by lymphatic drainage. This eventually leads to fluid leakage in the alveoli (alveolar edema) and to leakage into the pleural space (pleural effusion). The distribution of the alveolar edema can be influenced by:             Pulmonic stenosis        Left pulmonary artery sometimes big

Surgery in great vessels (aortic coarctation repair, Blalock-Taussig shunt creation, closure of patent ductus arteriosus) became common after the turn of the century and falls in the domain of cardiac surgery, but technically cannot be considered heart surgery. One of the more commonly known cardiac surgery procedures is the coronary artery bypass graft (CABG), also known as "bypass surgery." In this procedure, vessels from elsewhere in the patient's body are harvested, and grafted to the coronary arteries to bypass blockages and improve the blood supply to the heart muscle.

Sometimes, the left atrial appendage may enlarge as well. A convexity at this contour means the left atrial appendage is enlarged and is seen in mitral valvular disease, usually mitral stenosis. A pleurectomy is a surgical procedure in which part of the pleura is removed. It is sometimes used in the treatment of pneumothorax and mesothelioma.[24]

The cardiothoracic ratio (CTR) is the ratio of the transverse diameter of the heart to the internal diameter of the chest at its widest point just above the dome of the diaphragm as measured on a PA chest film. An increased cardiac silhouette is almost always the result of cardiomegaly, but occasionally it is due to pericardial effusion or even fat deposition. The heart size is considered too large when the CTR is > 50% on a PA chest x-ray. A CTR of > 50% has a sensitivity of 50% for CHF and a specificity of 75-80%. An increase in left ventricular volume of at least 66% is necessary before it is noticeable on a chest x-ray. This is the smooth inner surface of the heart chamber, which consist of the simple squamous epithelium over a layer or connective tissue (Stephen 1988). Cardiothoracic ratio has been a useful index of cardiac dilatation, and a value of 50% is generally There was no relationship between left ventricular end-diastolic dimension and the cardiothoracic.. Pleural effusion is not always visible as a meniscus in the costophrenic angle. A subpulmonic effusion may follow the contour of the diaphragm making it tricky to discern. In these cases, the only way to detect pleural effusion, is when you notice that there is an increased distance between the stomach bubble and the lung. The stomach is normally located directly under the diaphragm, so, on an erect PA radiograph, the stomach bubble should always appear in close proximity to the diaphragm and the lung.

The cardiothoracic ratio is measured on a PA chest x-ray, and is the ratio of maximal horizontal cardiac diameter to maximal horizontal thoracic diameter (inner edge of ribs/edge of pleura) Pulmonary reserve is measured by spirometry. If there is no evidence of undue shortness of breath or diffuse parenchymal lung disease, and the FEV1 exceeds 2 litres or 80% of predicted, the person is fit for pneumonectomy. If the FEV1 exceeds 1.5 litres, the patient is fit for lobectomy.[33] On the left a patient with CHF. There is an increase in heart size compared to the old film. Other signs of CHF are visible, such as redistribution of pulmonary flow, interstitial edema and some pleural fluid.

Surgeons realized the limitations of hypothermia – complex intracardiac repairs take more time and the patient needs blood flow to the body, particularly to the brain. The patient needs the function of the heart and lungs provided by an artificial method, hence the term cardiopulmonary bypass. John Heysham Gibbon at Jefferson Medical School in Philadelphia reported in 1953 the first successful use of extracorporeal circulation by means of an oxygenator, but he abandoned the method, disappointed by subsequent failures. In 1954 Lillehei realized a successful series of operations with the controlled cross-circulation technique in which the patient's mother or father was used as a 'heart-lung machine'. John W. Kirklin at the Mayo Clinic in Rochester, Minnesota started using a Gibbon type pump-oxygenator in a series of successful operations, and was soon followed by surgeons in various parts of the world.             Aortic stenosis               Ascending aorta prominent 4.               Increased flow

Both on the chest x-ray and on the CT the edema is gravity dependent and differences in density can be measured.The only portion of the left atrium visible from the front is the left atrial appendages, which lies side of the origin of the pulmonary trunk. The lungs normally covers most of the anterior surface of the heart especially during inspiration having only a small area opposed to the back of the sternum and left ribs (Sokolow 1977).This is the thick middle layer of the heart, which composed of cardiac muscle cells and is responsible for the ability of the heart to contract, (Stephen 1988).

Under normal conditions dynamic ultrasound will demonstrate changes in caliber of the IVC. These changes in caliber can be attributed to variations in blood flow in the IVC in accordance with the respiratory and cardiac cycles. The advantage of a single measurement of that it can be held to be compared in serial films. At difference of 2cm is held to be a significant change. This applies only when the heart is originally normal (Sutton 1985). The cardiothoracic ratio (CTR) shows the relationship between the size of the heart and the size of the Showing page 1.

The heart wall is composed of the three layers of tissue, namely the; epicardium, myocardium and endocardium (Stephen 1988). The epicardium and the visceral pericardium are two names for the same structure. The sinus pericardium is called epicardium when considered a part of the heart and the visceral pericardium when considered a part of the pericardium (Stephen 1988).Pleural effusion is bilateral in 70% of cases of CHF. When unilateral, it is slightly more often on the right side than on the left side. There has to be at least 175 ml of pleural fluid, before it will be visible on a PA image as a meniscus in the costophrenic angle. On a lateral image effusion of > 75 ml can be visible. If pleural effusion is seen on a supine chest film, it means that there is at least 500 ml present.

by McHugh, T. J., Forrester, J. S., Adler, L., et al. Ann. Intern. Med., 1972; 76:29-33 On the left a patient with ARDS. There is alveolar edema in both lungs. Notice that the VPW is normal. The vessels in the upper lobes are not dilated and the cardiac silhouette is not enlarged.

            Can’t be                    Presupposes left atrial enlargement A latter report by comeau and white in 1942 found that 15 to 25% of normal patient had a cardiothoracic ratio greater than 0.5 or 50% and advised that using CT ratio prediction labels based upon six, image technique and phase of respiration.

Cardiothoracic ratio is the ratio between the transverse diameter of the cardiac silhouette and the Although CT ratio is more objective in assessing the heart size, subjective grading into borderline..

For many people, cardiomegaly is asymptomatic. For others, if the enlarged heart begins to affect the body's ability to pump blood effectively, then symptoms associated with congestive heart failure may arise, including:[13] In this article we will discuss the radiographic signs of congestive heart failure on the chest X-ray. Young females may normally have prominence of the MPA but rarely does the main pulmonary artery project beyond the tangent. If the answer to question A “Is the left atrium enlarged” is yes, then look at the pulmonary vasculature. A cardiothoracic surgeon is a specialist who operates on the heart, lungs and other thoracic (chest) organs. As well as performing surgery, they also diagnose and treat diseases of these organs

Maurice Sokolow (1997) Physiology of the circulatory system clinical cardiology first edition large medical publication carlifornia PP1-9 The cardiothoracic ratio (CTR) is the ratio of the transverse diameter of the heart to the internal diameter of the chest at its widest point just above the dome of the diaphragm as measured on a PA.. Artery-to-bronchus ratio Normally the vessels in the upper lobes are smaller than the accompanying bronchus with a ratio of 0.85 (3). At the level of the hilum they are equal and in the lower lobes the arteries are larger with a ratio of 1.35. When there is redistribution of pulmonary blood flow there will be an increased artery-to-bronchus ratio in the upper and middle lobes. This is best visible in the perihilar region. Experts at NYU Langone's Department of Cardiothoracic Surgery work together to advance research, education, and clinical practice

by M Pistolesi, E N Milne, M Miniati and C Giuntini July 1984 Radiology, 152, 9-17. In non-small cell lung cancer staging, stages IA, IB, IIA, and IIB are suitable for surgical resection.[32] The two main entities in the differential diagnosis for a dilated or delta-shaped heart are cardiomyopathy and pericardial effusion.

What is the abbreviation for Cardiothoracic ratio? Cardiothoracic ratio can be abbreviated as CTR. CTR - Cardiothoracic ratio in Medical by AcronymsAndSlang.com Cardiothoracic ratio (CTR), the ratio of cardiac diameter (CD) to thoracic diameter (TD), is a useful screening method to detect cardiomegaly, but is reliable only on posteroanterior chest radiography.. Notice that even within each lobe there is a gravity dependent difference in density. This is only seen when the consolidations are the result of transudate like in CHF. This is not seen when the consolidations are the result of exsudate due to infection, blood due to hemorrhage or when there is a capillary leak like in ARDS.

The Association of Cardiothoracic Anaesthetists and The Society for Cardiothoracic Surgery in 2012 annual meeting & cardiothoracic forum. 18-20 April 2012 Manchester Central.. * With grateful acknowledgement to Bernard J. Ostrum, MD, who along with his father Joseph Ostrum, MD, both radiologists and both teachers, developed this approach to the diagnosis of heart disease by chest x-ray. A retrospective study was carried out in the university of Maiduguri Teaching Hospital, Department of Radiology, and using normal chest radiograph of two hundred and ninety-one (291) patients. Cardiothoracic ratio: Related Topics. These medical condition or symptom topics may be relevant to medical information for Cardiothoracic ratio

In normal people, in the erect position, the blood flow to the bases is greater than the blood flow to the apices.  This is due to the effect of gravity. In normal people, the size of the vessels at the base will therefore be greater than the size of the vessels at the apex. Series of developmental processes later leads to formation of a horse-shoe shaped endothelial lined tube surrounded by myoblasts in the cardiogenic field. In addition to cardiogenic region, other clusters of angiogenic cells appear bilaterally, parallel and close to the midline of the embryonic shield. These   clusters acquire a lumen and form a pair of longitudinal vessel called dorsal aorta. These vessels later gained connections via the aortic arches with the horseshoe shaped region that form the heart tube. by Gamsu G,Kaufman K ,Swann S ,Brito A. Invest Radiol 1979 ; 14: 261-269 A straight line drawn near the rule meddled of the heart shadow. Another line as in “a” from the right heart border to order to the first line was drown. A third line was drown from the left heart co-order furthest from the in the middle of the heart shown as the “b”. The two were then added together, the cardiothoracic rube as the own of the line “a” and “b” divided by the largest transverse internal diameter of the thoracic cage as shown on the figure 3.1 below.On the left images of a patient with signs of CHF. At first glance you might get the impression that there is a high position of the diaphragm. However when you notice the increased distance of the stomach air bubble to the lung base, you realize that there is a large amount of pleural fluid on both sides (arrow).
