All technetium isotopes are radioactive. Technetium 99m (m=metastable) which is the decay product of Molybdenum 99, has a half-life of about 6 hours and is used diagnostically as a radioactive imaging agent. Technetium 99 which is a decay product of technetium 99m, has a half-life of 210,000 years.
The measurement of visualization by radiation of any organ after a radionuclide has been injected into its blood supply. It is used to diagnose heart, liver, lung, and other diseases and to measure the function of those organs, except renography, for which RADIOISOTOPE RENOGRAPHY is available.
Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchronizer or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (VENTRICULOGRAPHY, FIRST-PASS).
Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over GATED BLOOD-POOL IMAGING for assessing right ventricular function.

An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.

Malfunction of Bjork-Shiley valve prosthesis in tricuspid position. (1/224)

Eight months after triple valve replacement with Bjork-Shiley tilting disc valves a patient developed symptoms and signs suggesting malfunction of the prosthesis in the tricuspid position. This was confirmed by echocardiography and angiocardiography, and at operation thedisc of the prosthesis was found to be stuck half-open by fibrin and clot. A further 11 patients with the same tupe of prosthesis in the triscupid position were then studied by phonocardiography and echocardiography. In one of these the prosthesis was found to be stuck and this was confirmed by angiocardiography and surgery. These 2 cases are reported in detail and the findings in the other 10 are discussed. The implications of this high incidence of malfunction of the Bjork-Shiley prosthesis in the tricuspid position are considered. Echocardiography appears to be essential in the follow-up of such patients.  (+info)

Pseudoaneurysm of the left ventricle progressing from a subepicardial aneurysm. (2/224)

A 56-year-old man presented with an inferior myocardial infarction and a huge pseudoaneurysm below the inferior surface of the left ventricle, which had progressed from a small subepicardial aneurysm over a 6-month period. Transthoracic echocardiography, Doppler color flow images, radionuclide angiocardiography, magnetic resonance imaging and contrast ventriculography all revealed an abrupt disruption of the myocardium at the neck of the pseudoaneurysm, where the diameter of the orifice was smaller than the aneurysm itself, and abnormal blood flows from the left ventricle to the cavity through the orifice with an expansion of the cavity in systole and from the cavity to the left ventricle with the deflation of the cavity in diastole. Coronary angiography revealed 99% stenosis at the atrioventricular nodal branch of the right coronary artery. At surgery the pericardium was adherent to the aneurysmal wall and a 1.5-cm orifice between the aneurysm and the left ventricle was seen. Pathological examination revealed no myocardial elements in the aneurysmal wall. The orifice was closed and the postoperative course was uneventful. Over-intense physical activity as a construction worker was considered to be the cause of the large pseudoaneurysm developing from the subepicardial aneurysm. These findings indicate that a subepicardial aneurysm may progress to a larger pseudoaneurysm, which has a propensity to rupture, however, it can be surgically repaired.  (+info)

Evolution of the ventricles. (3/224)

We studied the evolution of ventricles by macroscopic examination of the hearts of marine cartilaginous and bony fish, and by angiocardiography and gross examination of the hearts of air-breathing freshwater fish, frogs, turtles, snakes, and crocodiles. A right-sided, thin-walled ventricular lumen is seen in the fish, frog, turtle, and snake. In fish, there is external symmetry of the ventricle, internal asymmetry, and a thick-walled left ventricle with a small inlet chamber. In animals such as frogs, turtles, and snakes, the left ventricle exists as a small-cavitied contractile sponge. The high pressure generated by this spongy left ventricle, the direction of the jet, the ventriculoarterial orientation, and the bulbar spiral valve in the frog help to separate the systemic and pulmonary circulations. In the crocodile, the right aorta is connected to the left ventricle, and there is a complete interventricular septum and an improved left ventricular lumen when compared with turtles and snakes. The heart is housed in a rigid pericardial cavity in the shark, possibly to protect it from changing underwater pressure. The pericardial cavity in various species permits movements of the heart-which vary depending on the ventriculoarterial orientation and need for the ventricle to generate torque or spin on the ejected blood- that favor run-off into the appropriate arteries and their branches. In the lower species, it is not clear whether the spongy myocardium contributes to myocardial oxygenation. In human beings, spongy myocardium constitutes a rare form of congenital heart disease.  (+info)

Evaluation of portable radionuclide method for measurement of left ventricular ejection fraction and cardiac output. (4/224)

Seventeen patients with coronary artery, valvular, or myopathic heart disease were studied to determine correlations of the cardiac output and ejection fraction when comparing the results obtained with a portable probe technique using 113mIn with those obtained with standard methods (cineangiographic, Fick, and dye dilution). With ejection fractions ranging from o.10 to 0.85, the coefficient of correlation was 0.90 when comparing cineangiographic and radionuclide techniques. Cardiac output determinations by the radionuclide technique also correlated well with standard methods (r equals 0.88). The radionuclide method shows promise as an accurate, safe, and simple method in the evaluation of cardiac function at the bedside.  (+info)

Effect of propranolol on left ventricular function, segmental wall motion, and diastolic pressure-volume relation in man. (5/224)

Precise quantitation of the effects of the non-selective beta adrenergic blocking drug propranolol (3.15 mg/kg body weight) on left ventricular function, segmental wall motion, and diastolic pressure-volume relation in man has been performed. High fidelity left ventricular pressure measurements and simultaneous single-plane angiocardiograms were recorded on a video disc and volumes calculated by a light-pen computer system. Systolic segmental wall motion was computer analysed using the long axis-quadrasection method. Patients were transvenously atrially paced to maintain a constant heart rate. The haemodynamic effects of propranolol may vary depending upon the extent of pre-existing myocardial disease. In some patients ventricular function, as measured by ejection fraction, may be reduced. This reduction in ejection fraction appears to result from overall reduction in segmental wall motion, but also from accentuation of segmental wall abnormalities. These results are consistent with the thesis that beta adrenergic blocking drugs may inhibit compensatory sympathetic mechanisms. The diastolic effects of propranolol may include quite substantial increases in ventricular volumes in those patients with impaired cardiac function. With respect to the intact human ventricle, propranolol may increase diastolic volume for a given level of ventricular pressure. Thus, in a static sense, the ventricle in these patients could be viewed as being more compliant after propranolol administration. However, the fact that the length-tension relation, as measured by the slope of the logarithmic pressure versus volume plot is unaltered by propranolol, suggests that the muscle comprising the ventricle itself exhibits no alteration in its passive elastic properties.  (+info)

Non-invasive left ventricular volume determination by two-dimensional echocardiography. (6/224)

Twenty patients undergoing routine left ventricular single-plane angiography have been investigated by an ultrasonic triggered B-scan technique to provide a two-dimensional cross-sectional image of the left ventricle in end-systole end-diastole. An area-length method has been used to establish the correlation between the angiographic and the echocardiographic assessments of left ventricular chamber volume (r equals 0.88) and ejection fraction (r equals 0.81). Differences between the two techniques are discussed, and it is concluded that in approximately 80 per cent of patients triggered B-scanning may provide a safe, non-invasive, and convenient technique for the determination of volumes and certain functional parameters, especially in patients with dilated hearts and irregular left ventricular shape, where M-scanning is known to be less reliable.  (+info)

Localization of left ventricular ischaemia in angina pectoris by cineangiography during exercise. (7/224)

Cineangiography of the left ventricle during exercise has been used in an attempt to define the area of ischaemic myocardium in patients suffering from angina pectoris in whom coronary artery surgery was contemplated. A correlation was established between the site of coronary artery obstruction and the area of abnormal myocardial contraction. This method of localization of regional left ventricular ischaemia may furnish useful diagnostic information when coronary reconstructive surgery is contemplated in patients with exercise-induced angina pectoris.  (+info)

Ejection phase indices of left ventricular performance in infants, children, and adults. (8/224)

A validatory study of quantitative single plane left ventricular cineangiography is presented, using human left ventricular casts ranging in size from 1.6 to 135 ml. Good correlation was found between actual and calculated volumes (r=0.967). 62 patient studies were carried out and the value of the usually calculated indices of left ventricular performance were compared to one another. Ejection fraction and mean rate of circumferential fibre shortening (mean Vcf) were found to be the best discriminators of abnormal left ventricular function, and, on the basis of the presented data, it is suggested that mean Vcf is the more sensitive index of left ventricular performance.  (+info)

The exercise electrocardiographic ST segment/heart rate slope accurately identifies three vessel coronary disease in patients with stable angina, but the method is less accurate in predischarge testing after recent myocardial infarction. To assess the effect of both recent (,3 weeks) infarction and remote (,8 weeks) Q wave infarction on the ST segment/heart rate slope, the predictive value of a slope greater than 6.0 μV/beat per min for the identification of three vessel coronary artery disease was evaluated in 113 patients.. The 58 patients with stable angina, including 17 with remote Q wave myocardial infarction, were similar to the 55 patients with recent myocardial infarction with respect to age and peak exercise heart rate. In patients with stable angina and no prior Q wave myocardial infarction, an ST segment/heart rate slope greater than 6.0 had a sensitivity of 92% (11 of 12), a specificity of 97% (28 of 29) and a positive predictive value of 92% (11 of 12) for three vessel coronary ...
Angiocardiography is contrast radiography of the heart and great vessels. A liquid radiocontrast agent, typically containing iodine, is injected into the bloodstream, then the tissues are examined using X-rays. To avoid dilution, the radiopaque material is typically introduced with a catheter, a process known as selective angiocardiography. Normally, rather than just a single image, hundreds of X-ray images are rapidly captured on high-speed serial media, such as 35 mm film or a digital imaging counterpart, thus allowing the motion to be observed. The process requires fasting before the test, with a sedative and an antihistamine being administered before the test. A catheter is introduced in to the artery in either radial artery or in femoral artery then the catheter is guided in to the heart chamber by moving it across the artery. A contrast medium is then introduced to the specific part through the catheter and during which a series of images are produced. Angiocardiography can be used to ...

Maximum and minimum volumes of the left atrium (LA) were calculated from the biplane angiocardiograms of 18 men and four women without significant heart disease.. The mean LA maximum volume was 63 cc ± 16 cc; the mean LA minimum volume was 31 cc±10 cc, and their difference, LA cyclic volume change, was 33 cc±13 cc. Larger LA volumes were associated with greater cyclic volume changes. LA cyclic volume changes constituted 38% of LV stroke volume.. No significant correlation between LA volumes and age, sex, surface area, heart rate, LV end-diastolic volume, LV stroke volume, or cardiac output was found.. Volume data in normal subjects support the thesis that the LA serves mainly as a reservoir and conduit for blood destined for the left ventricle and that its contractile function is less important. The relation of LA volume change to LV stroke volume appears abnormal in chronic mitral regurgitation and constrictive pericarditis.. ...

Congenital heart disease (CHD) is generally thought to be a difficult and challenging subject. In this textbook authors have made an effort to make CHD comprehensive with a strong clinical bias so that physicians caring for the newborn, infant and the children can have an early diagnosis with accuracy so as to prevent high morbidity and mortality. Recent advances in percutaneous interventions and surgical techniques have made the outlook for CHD look brighter today. In this book all importance has been given to basic anatomy, embryology, pathophysiology and clinical features besides basic investigations starting from ECG, chest X-ray, echocardiography to invasive procedures like cardiac catheterization and angiocardiography keeping a link between pre-echo era and present day investigatory tools. For each disease a guideline is provided for management so as to initiate treatment with existing facilities and to make a decision for referral to appropriate cardiac center at the right time.

Double outlet right ventricle is a rare birth defect of the heart.. The heart has 2 upper collecting chambers (right and left atrium), 2 lower pumping chambers (right and left ventricle), 1 artery leaving the right ventricle (pulmonary artery) and 1 leaving the left ventricle (aorta).. In a normal heart, the aorta leaves the left ventricle, carrying oxygen-rich (red) blood to the body. The pulmonary artery leaves the right ventricle, carrying oxygen-poor (blue) blood to the lungs.. In double outlet right ventricle, both of the hearts outlets - the pulmonary artery and the aorta - exit abnormally from the right ventricle. This causes the oxygen-rich and oxygen-poor blood to mix together before leaving the heart.. Many kinds of heart defects fall into the category of double outlet right ventricle. They all share the feature that the aorta and pulmonary artery both exit from the right ventricle. In addition, other parts of the heart may be different.. In double outlet right ventricle, there is ...

Click picture to show/hide bloodflows). Pathophysiology. The hemodynamics involved with double outlet right ventricle are dependent on the anatomy of the great vessels and associated defects. Decreased arterial oxygen saturation is almost always present, but as a result of wide variation in anatomy, patients may or may not appear cyanotic and/or develop congestive heart failure. Patients may even be asymptomatic altogether. Transposition-like physiology occurs with inadequate circulatory mixing of oxygenated and deoxygenated blood.. Therapy. Management of double outlet right ventricle in early infancy depends on associated defects. When operative therapy is required, the type of surgical correction depends on the anatomic characteristics of the defect and amenability. The goal of the surgical treatment is complete anatomic repair, which means connecting the left ventricle to the aorta, the right ventricle to the pulmonary artery, and closure of the VSD.

Sixty-three patients of postinfarction left ventricular aneurysm (26 surgical cases and 37 medical cases) were analysed in the left ventricular performance, the survival rate, and the subjective complaints. In the surgical cases, the left ventricular performance improved significantly, but no significant changes were noted in the medical cases. The left ventricular function curves were inclined toward the upper left direction in the surgical cases. Whereas in the medical cases they were declined toward the lower right direction. No cardiac death occurred among the surgical cases, but it occurred in 8 patients, or 21.6% in the medical cases. Five year cumulative survival rate was 95.7% and adjusted survival rate was 100% in the surgical cases, but in the medical cases it was 80.7% and 86.8%, respectively.

GREAT points you raise on this case Steve! - including the need to put all pieces in the equation together in forming your clinical conclusion. That is, the initial ECG was not at all diagnostic - but, in context of the history of severe chest pain the entire previous night - with ongoing chest pain at the time of this tracing - with positivity (albeit slight) in the initial troponin value - the onus is on us to determine what is old vs subacute with indication for prompt cath (that in retrospect should have been done before the 2nd troponin came back). And although subtle - the 2nd ECG you show IS diagnostic (!) - because we see reversal of inferior and reciprocal changes in aVL. I would add Learning Points #7 ( = put all pieces together when forming your clinical impression) - and #8 (acute inferior MI sometimes manifest the most SUBTLE of changes - so be aware of this, and dont necessarily expect obvious ECG abnormalities).

The CA3 region expressed TRPV4 mRNA at higher levels than did other brain regions (Fig. 1). Aihara et al. (2001) reported that hypothermic treatment (from 35 to 25°C) of CA3 hippocampal pyramidal neurons reduced the EPSP slope in a temperature-dependent manner, and that neuronal activities including membrane properties fully recovered when the temperature was returned to 35°C even from as low as 15°C. Temperature-dependent reciprocal changes in hippocampal field activity were also reported (Karlsson and Blumberg, 2004). In that study, the authors recorded spontaneous hippocampal activity along the rat CA1-dentate gyrus axis using multisite silicon electrodes at brain temperatures of 27 and 37°C. Theta and gamma activities were detected at 37°C, but not at 27°C. This result might be partially explained by TRPV4-mediated depolarization and firing, which we observed in hippocampal neurons (Fig. 6), although oxygen consumption could be involved at this temperature as well. Together, TRPV4 ...

Double outlet right ventricle (DORV) is a rare congenital disorder where both of the great arteries, namely the aorta and the pulmonary artery, arise from the right ventricle.
All study subjects underwent gated equilibrium radionuclide angiocardiography at rest and during the last 5 min of a 15-min peripheral intravenous infusion of dobutamine (Dobutrex, Eli Lilly & Co., Indianapolis, Indiana) at a dose of 10 μg/kg/min. Right and left ventricular ejection fractions were measured after modified in vivo red blood cell labeling (25-30mCi Technetium-99m pertechnetate) according to standardized techniques (28). Data were acquired in electrocardiographic-synchronized frame mode (16 frames/RR cycle) in 64 × 64 computer matrix. Global LVEF was computed from the left anterior oblique image using validated and standardized software (29). A varying left ventricular region of interest and a cycle-dependent background region were used. The computer software automatically determines left ventricular edges and background, but also allows for operator interaction as may be necessary in patients with intense radiotracer accumulation adjacent to the left ventricle. Left ventricular ...

The patent ductus can be diagnosed with great accuracy entirely on clinical grounds. The clinical diagnosis can readily be confirmed by radiology and phonocardiography. Cardiac catheterization is used only in complicated cases and angiocardiography on very rare occasions. The long-term prognosis even of uncomplicated cases is poor, most having severe symptoms and incapacity in adult life when their responsibilities to their family are greatest. The pathology is remediable by fairly simple measures ca rrying a low mortality. Surgery should be employed in these cases whilst the patients' are young, at a time when intervention is safe and before irreversible pathological changes have occurred in the pulmonary arterial tree.

Over the 3-year study period, there was myopic progression in placebo-treated eyes of −1.57 D, which was associated with a reduction in K and increase in LT, VCD, and AL. The association between increasing VCD and AL with increasing myopia is well described.8,9 The changes in ACD and LT also have been explored in several studies.10-12 In the cross-sectional population-based Singapore Cohort of Risk Myopia study in which young myopic children were followed for 5 years, the ACD and LT demonstrate a U-shaped change, with ACD deepening until approximately age 10 years before shallowing, and with LT thinning until age 9 to 10 years before thickening.9 A Taiwanese study reported a similar decrease in LT from age 7 to 11 years and subsequent thickening with reciprocal changes in ACD.10 A similar U-shaped change in LT was noted by Twelker et al.11 in the Orinda Longitudinal Study of Myopia study, but change in LT was slower and change in ACD showed a slow and unidirectional increase over time. Van ...
The best way to classify and diagnose abnormal heart positions is by segmentary approaches, first identifying the position of the organs and the atria, then the ventricles, and finally the large vessels. The determination of visceroatrial situs can be made by radiographic determination of the position of the abdominal organs and tracheal bifurcation, to recognise the left and right bronchi, and by ultrasonography. The atria situs is related to visceral and pulmonary situs. In situs solitus, the organs are in their normal position (stomach and spleen to the left, liver to the right); the right tri-lobed lung is located on the right and the left bi-lobed on the left; and the right atrium is located on the right, while the left atrium is located on the left. When the abdominal organs and the lungs are inverted-a condition known as situs inversus-the left atrium is located on the right and the right atrium on the left. If the visceroatrial situs cannot be easily established, this is a condition ...

Ballistic photons are the light photons that travel through a scattering (turbid) medium in a straight line. Also known as ballistic light. If laser pulses are sent through a turbid medium such as fog or body tissue, most of the photons are either randomly scattered or absorbed. However, across short distances, a few photons pass through the scattering medium in straight lines. These coherent photons are referred to as ballistic photons. Photons that are slightly scattered, retaining some degree of coherence, are referred to as snake photons. If efficiently detected, there are many applications for ballistic photons especially in coherent high resolution medical imaging systems. Ballistic scanners (using ultrafast time gates) and optical coherence tomography (OCT) (using the interferometry principle) are just two of the popular imaging systems that rely on ballistic photon detection to create diffraction-limited images. Advantages over other existing imaging modalities (e.g., ultrasound and ...

Modifiers: Prior to this implementation, DMAS allowed claim lines with modifiers 24, 25, 57, 59 to bypass the CCI/ClaimCheck editing process. With this implementation, DMAS now only allows the Medicaid NCCI associated modifiers as identified by CMS for the Medicaid NCCI. The modifier indicator currently applies to the PTP edits. The application of this modifier is determined by the modifier indicator of "1"or "0" in the listing of the NCCI PTP column code. If the column one, column two code combination has a modifier indicator of "1", a modifier is allowed and both codes will pay. If the modifier indicator is "0", the modifier is not allowed and the column two code will be denied. The MUE edits do not contain a modifier indicator table on the edit table. Per CMS, modifiers may only be applied if the clinical circumstances justify the use of the modifier. A provider cannot use the modifier just to bypass the edit. The recipients medical record must contain documentation to support the use of the ...
