The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.Cardiopulmonary Bypass: Diversion of the flow of blood from the entrance of the right atrium directly to the aorta (or femoral artery) via an oxygenator thus bypassing both the heart and lungs.Heart Auscultation: Act of listening for sounds within the heart.Cohort Studies: Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.Magnetic Resonance Imaging, Cine: A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo MRI sequence with retrospective ECG-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualized.Cardiac Output, Low: A state of subnormal or depressed cardiac output at rest or during stress. It is a characteristic of CARDIOVASCULAR DISEASES, including congenital, valvular, rheumatic, hypertensive, coronary, and cardiomyopathic. The serious form of low cardiac output is characterized by marked reduction in STROKE VOLUME, and systemic vasoconstriction resulting in cold, pale, and sometimes cyanotic extremities.Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Ultrasonography, Interventional: The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.Chi-Square Distribution: A distribution in which a variable is distributed like the sum of the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another.Myoblasts, Cardiac: Precursor cells destined to differentiate into cardiac myocytes (MYOCYTES, CARDIAC).Pericardiectomy: Surgical excision (total or partial) of a portion of the pericardium. Pericardiotomy refers to incision of the pericardium.Carcinoid Heart Disease: Cardiac manifestation of gastrointestinal CARCINOID TUMOR that metastasizes to the liver. Substances secreted by the tumor cells, including SEROTONIN, promote fibrous plaque formation in ENDOCARDIUM and its underlying layers. These deposits cause distortion of the TRICUSPID VALVE and the PULMONARY VALVE eventually leading to STENOSIS and valve regurgitation.Aorta: The main trunk of the systemic arteries.Phonocardiography: Graphic registration of the heart sounds picked up as vibrations and transformed by a piezoelectric crystal microphone into a varying electrical output according to the stresses imposed by the sound waves. The electrical output is amplified by a stethograph amplifier and recorded by a device incorporated into the electrocardiograph or by a multichannel recording machine.Thrombolytic Therapy: Use of infusions of FIBRINOLYTIC AGENTS to destroy or dissolve thrombi in blood vessels or bypass grafts.United StatesOut-of-Hospital Cardiac Arrest: Occurrence of heart arrest in an individual when there is no immediate access to medical personnel or equipment.Incidence: The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.Dogs: The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065)Heparin: A highly acidic mucopolysaccharide formed of equal parts of sulfated D-glucosamine and D-glucuronic acid with sulfaminic bridges. The molecular weight ranges from six to twenty thousand. Heparin occurs in and is obtained from liver, lung, mast cells, etc., of vertebrates. Its function is unknown, but it is used to prevent blood clotting in vivo and vitro, in the form of many different salts.

Transcatheter closure of patent foramen ovale using the Amplatzer septal occluder to prevent recurrence of neurological decompression illness in divers. (1/3859)

OBJECTIVE: Large flap valve patent foramens may cause paradoxical thromboembolism and neurological decompression illness in divers. The ability of a self expanding Nitinol wire mesh device (Amplatzer septal occluder) to produce complete closure of the patent foramen ovale was assessed. PATIENTS: Seven adults, aged 18-60 years, who had experienced neurological decompression illness related to diving. Six appeared to have a normal atrial septum on transthoracic echocardiography, while one was found to have an aneurysm of the interatrial septum. METHODS: Right atrial angiography was performed to delineate the morphology of the right to left shunt. The defects were sized bidirectionally with a precalibrated balloon filled with dilute contrast. The largest balloon diameter that could be repeatedly passed across the septum was used to select the occlusion device diameter. Devices were introduced through 7 F long sheaths. All patients underwent transthoracic contrast echocardiography one month after the implant. RESULTS: Device placement was successful in all patients. Device sizes ranged from 9-14 mm. The patient with an aneurysm of the interatrial septum had three defects, which were closed with two devices. Right atrial angiography showed complete immediate closure in all patients. Median (range) fluoroscopy time was 13.7 (6-35) minutes. Follow up contrast echocardiography showed no right to left shunting in six of seven patients and the passage of a few bubbles in one patient. All patients have been allowed to return to diving. CONCLUSION: The Amplatzer septal occluder can close the large flap valve patent foramen ovale in divers who have experienced neurological decompression illness. Interatrial septal aneurysms with multiple defects may require more than one device.  (+info)

Chronic radiodermatitis following cardiac catheterisation: a report of two cases and a brief review of the literature. (2/3859)

Cardiac angiography produces one of the highest radiation exposures of any commonly used diagnostic x ray procedure. Recently, serious radiation induced skin injuries have been reported after repeated therapeutic interventional procedures using prolonged fluoroscopic imaging. Two male patients, aged 62 and 71 years, in whom chronic radiodermatitis developed one to two years after two consecutive cardiac catheterisation procedures are reported. Both patients had undergone lengthy procedures using prolonged fluoroscopic guidance in a limited number of projections. The resulting skin lesions were preceded, in one case, by an acute erythema and took the form of a delayed pigmented telangiectatic, indurated, or ulcerated plaque in the upper back or below the axilla whose site corresponded to the location of the x ray tube during cardiac catheterisation. Cutaneous side effects of radiation exposure result from direct damage to the irradiated tissue and have known thresholds. The diagnosis of radiation induced skin injury relies essentially on clinical and histopathological findings, location of skin lesions, and careful medical history. Interventional cardiologists should be aware of this complication, because chronic radiodermatitis may result in painful and resistant ulceration and eventually in squamous cell carcinoma.  (+info)

The effect of race and sex on physicians' recommendations for cardiac catheterization. (3/3859)

BACKGROUND: Epidemiologic studies have reported differences in the use of cardiovascular procedures according to the race and sex of the patient. Whether the differences stem from differences in the recommendations of physicians remains uncertain. METHODS: We developed a computerized survey instrument to assess physicians' recommendations for managing chest pain. Actors portrayed patients with particular characteristics in scripted interviews about their symptoms. A total of 720 physicians at two national meetings of organizations of primary care physicians participated in the survey. Each physician viewed a recorded interview and was given other data about a hypothetical patient. He or she then made recommendations about that patient's care. We used multivariate logistic-regression analysis to assess the effects of the race and sex of the patients on treatment recommendations, while controlling for the physicians' assessment of the probability of coronary artery disease as well as for the age of the patient, the level of coronary risk, the type of chest pain, and the results of an exercise stress test. RESULTS: The physicians' mean (+/-SD) estimates of the probability of coronary artery disease were lower for women (probability, 64.1+/-19.3 percent, vs. 69.2+/-18.2 percent for men; P<0.001), younger patients (63.8+/-19.5 percent for patients who were 55 years old, vs. 69.5+/-17.9 percent for patients who were 70 years old; P<0.001), and patients with nonanginal pain (58.3+/-19.0 percent, vs. 64.4+/-18.3 percent for patients with possible angina and 77.1+/-14.0 percent for those with definite angina; P=0.001). Logistic-regression analysis indicated that women (odds ratio, 0.60; 95 percent confidence interval, 0.4 to 0.9; P=0.02) and blacks (odds ratio, 0.60; 95 percent confidence interval, 0.4 to 0.9; P=0.02) were less likely to be referred for cardiac catheterization than men and whites, respectively. Analysis of race-sex interactions showed that black women were significantly less likely to be referred for catheterization than white men (odds ratio, 0.4; 95 percent confidence interval, 0.2 to 0.7; P=0.004). CONCLUSIONS: Our findings suggest that the race and sex of a patient independently influence how physicians manage chest pain.  (+info)

Prediction of life expectancy in patients with primary pulmonary hypertension. A retrospective nationwide survey from 1980-1990. (4/3859)

Primary pulmonary hypertension (PPH) is a progressive disease of unknown etiology usually followed by death within 5 years after diagnosis. Although heart-lung or lung transplantation is now offered to patients with advanced PPH, adequate criteria assessing an accurate prediction of life expectancy in PPH has been difficult to establish. The aims of this study were to identify the characteristic features associated with a poor prognosis in patients with PPH, and to attempt to establish an individual prognostic index that predicts with great accuracy survival or death of PPH after one year, thereby helping to define criteria for patient selection for transplantation. In 1991, a retrospective nation-wide survey on PPH was conducted in Japan, and the clinical and cardiorespiratory variables of 223 PPH cases (female; 144, male; 79) in the period from 1980-1990 were obtained. The mean pulmonary arterial pressure (PPA) was 57.5+/-17.2 mm Hg (mean+/-SD), and the overall median survival time was 32.5 months since the first diagnostic catheterization. The characteristic features of 61 patients who died within one year of catheterization (Nonsurvivors group) were compared to 141 patients who survived one year or more from the time of catheterization (Survivors group). Among several clinical and cardiorespiratory variables, heart rate, PPA, right atrial pressure (PRA), stroke volume index (SI), pulmonary vascular resistance, and partial pressure of carbon dioxide (PaCO2) were significantly different between the two groups. As the independent factors, PPA, PRA, SI, and PaCO2 were selected for the multiple logistic analysis. Using a 0.7 probability cut-point to separate Nonsurvivors from Survivors, 84.6% of Nonsurvivors and Survivors could be correctly predicted from this logistic regression equation. Predictive equations like the present preliminary one can be used in the future to better assess life expectancy in patients with PPH in whom transplantation will be considered.  (+info)

LocaLisa: new technique for real-time 3-dimensional localization of regular intracardiac electrodes. (5/3859)

BACKGROUND: Estimation of the 3-dimensional (3D) position of ablation electrodes from fluoroscopic images is inadequate if a systematic lesion pattern is required in the treatment of complex arrhythmogenic substrates. METHODS AND RESULTS: We developed a new technique for online 3D localization of intracardiac electrodes. Regular catheter electrodes are used as sensors for a high-frequency transthoracic electrical field, which is applied via standard skin electrodes. We investigated localization accuracy within the right atrium, right ventricle, and left ventricle by comparing measured and true interelectrode distances of a decapolar catheter. Long-term stability was analyzed by localization of the most proximal His bundle before and after slow pathway ablation. Electrogram recordings were unaffected by the applied electrical field. Localization data from 3 catheter positions, widely distributed within the right atrium, right ventricle, or left ventricle, were analyzed in 10 patients per group. The relationship between measured and true electrode positions was highly linear, with an average correlation coefficient of 0.996, 0.997, and 0.999 for the right atrium, right ventricle, and left ventricle, respectively. Localization accuracy was better than 2 mm, with an additional scaling error of 8% to 14%. After 2 hours, localization of the proximal His bundle was reproducible within 1.4+/-1.1 mm. CONCLUSIONS: This new technique enables accurate and reproducible real-time localization of electrode positions in cardiac mapping and ablation procedures. Its application does not distort the quality of electrograms and can be applied to any electrode catheter.  (+info)

Detection of adenoviral genome in the myocardium of adult patients with idiopathic left ventricular dysfunction. (6/3859)

BACKGROUND: The use of molecular biological techniques has demonstrated the importance of enteroviral infection of the myocardium in the pathogenesis of myocarditis and dilated cardiomyopathy in adults and adenovirus and enterovirus infection in children. The aim of this study was to determine the frequency of adenoviral infection of the myocardium of adults with impaired left ventricular function of unknown origin. METHODS AND RESULTS: Nested polymerase chain reaction (nPCR) was used to determine the frequency of detection of adenoviral DNA and enteroviral RNA in myocardial tissue samples from 94 adult patients with idiopathic left ventricular dysfunction and 14 control patients. Histological and immunohistological analyses were performed to detect myocardial inflammation. Adenoviral genomic DNA was detected by nPCR in 12 of the 94 patients with left ventricular dysfunction (in each case, adenovirus type 2), whereas enteroviral RNA was detected in another 12 patients. All control samples were negative for both viruses. In all patients, active myocarditis was excluded according to the Dallas criteria. However, there was significantly decreased CD2, CD3, and CD45RO T lymphocyte counts in the adenovirus-positive group compared with the adenovirus-negative group (P<0.05), whereas no differences were associated with enterovirus infection. CONCLUSIONS: Although enteroviruses are an important causative agent in the pathogenesis of myocarditis and dilated cardiomyopathy, this study shows that adenovirus infection is also important in the pathogenesis of left ventricular failure in adults. However, the pathogenetic basis of disease associated with adenovirus infection may be different than that after infection with other agents, particularly with respect to activation of the host immune response.  (+info)

Transcatheter occlusion of a post-Fontan residual hepatic vein to pulmonary venous atrium communication using the Amplatzer septal occluder. (7/3859)

A residual hepatic vein to left atrial communication may result in progressive cyanosis after the Fontan procedure. This problem has usually been treated surgically by ligation or re-inclusion of the residual hepatic vein in the Fontan circulation. Previous attempts at transcatheter closure of such veins have been unsuccessful. An Amplatzer septal occluder was successfully used for transcatheter closure of a post-Fontan hepatic vein to pulmonary venous atrium fistula in an 8 year old boy.  (+info)

Primary angioplasty versus systemic thrombolysis in anterior myocardial infarction. (8/3859)

OBJECTIVES: This study compares the efficacy of primary angioplasty and systemic thrombolysis with t-PA in reducing the in-hospital mortality of patients with anterior AMI. BACKGROUND: Controversy still exists about the relative benefit of primary angioplasty over thrombolysis as treatment for AMI. METHODS: Two-hundred and twenty patients with anterior AMI were randomly assigned in our institution to primary angioplasty (109 patients) or systemic thrombolysis with accelerated t-PA (111 patients) within the first five hours from the onset of symptoms. RESULTS: Baseline characteristics were similar in both groups. Primary angioplasty was independently associated with a lower in-hospital mortality (2.8% vs. 10.8%, p = 0.02, adjusted odds ratio 0.23, 95% confidence interval 0.06 to 0.85). During hospitalization, patients treated by angioplasty had a lower frequency of postinfarction angina or positive stress test (11.9% vs. 25.2%, p = 0.01) and less frequently underwent percutaneous or surgical revascularization after the initial treatment (22.0% vs. 47.7%, p < 0.001) than did patients treated by t-PA. At six month follow-up, patients treated by angioplasty had a lower cumulative rate of death (4.6% vs. 11.7%, p = 0.05) and revascularization (31.2% vs. 55.9%, p < 0.001) than those treated by t-PA. CONCLUSIONS: In centers with an experienced and readily available interventional team, primary angioplasty is superior to t-PA for the treatment of anterior AMI.  (+info)

Diagnostic cardiac catheterization and coronary angiography are considered the gold standard in the assessment of the anatomy and physiology of the heart and its associated vasculature. In 1929, Forssmann demonstrated the feasibility of cardiac catheterization in humans when he passed a urological catheter from a vein in his arm to his right atrium and documented the catheters position in the heart by x-ray. In the 1940s, Cournand and Richards applied this technique to patients with cardiovascular disease to evaluate cardiac function. These three physicians were awarded the Nobel Prize in 1956. In 1958, Sones inadvertently performed the first selective coronary angiography when a catheter in the left ventricle slipped back across the aortic valve, engaged the right coronary artery, and power-injected 40 mL of contrast down the vessel. The resulting angiogram provided superb anatomic detail of the artery, and the patient suffered no adverse effects. Sones went on to develop selective coronary ...

The working staff, particularly cardiologists who perform these procedures, have the highest potential risk of receiving high radiation doses due to close contact with patients. The purpose of this study was to measure and evaluate the accumulated radiation dosage of the cardiologists while they were performing clinical procedures in the cardiac catheterization laboratory. The working environment of the catheterization laboratory was also monitored for radiation. Methods. Thermoluminescent dosimeters (TLDs) with very high sensitivity were employed for dose evaluations. They were taped to various parts of the body ...

To avoid venous puncture, a new concept for standby cardiac pacing during percutaneous transluminal coronary angioplasty (PTCA) and diagnostic cardiac catheterization was developed. It uses an arterial guidewire as a unipolar pacing electrode with the second electrode attached to the skin. The system was tested in 25 coronary arteries of 22 patients undergoing PTCA and in the left ventricles of 10 patients undergoing diagnostic cardiac catheterization. Coronary pacing via the guidewire used for directing the balloon catheter was possible in all patients and in 24 of the 25 coronary arteries attempted. Maximum duration of pacing was 8 min. Threshold currents ranged from 1 to 15 mA (mean 5.7). Left ventricular pacing via the same wires or standard wires used for introduction of diagnostic or guiding catheters was possible in all patients and was maintained for up to 10 min. Threshold currents ranged from 1 to 7 mA (mean 3.9). Neither method for pacing produced adverse effects during these short ...
The risk of major complications during diagnostic cardiac catheterization procedure is usually less than 1%, and the risk and the risk of mortality of 0.05% for diagnostic procedure. For any patient, the complication rate is dependent on multiple factors and is dependent on the demographics of the patient, vascular anatomy, co-morbid conditions, clinical presentation, the procedure being performed, and the experience of the operator. The complications can be minor as discomfort at the site of catheterization to major ones like death.. But there are very serious complications of the procedure that can result in death or serious disability.. From a recently updated review of cath complications. Local Vascular Complications.

The concept of diastolic heart failure has generated a fair amount of controversy, with some authorities questioning whether specific evidence of diastolic dysfunction has been found in patients diagnosed with this condition. Zile and colleagues described findings from diagnostic studies performed on a series of patients diagnosed with diastolic heart failure.. The study authors enrolled 47 patients scheduled for diagnostic cardiac catheterizations who had heart failure and normal left ventricular ejection fractions. These patients were compared with 10 control patients who had no evidence of heart failure but underwent catheterization for the evaluation of chest pain and were found to have normal coronary arteries and systolic function. During cardiac catheterization, a micromanometer was inserted into the left ventricle to measure precisely left ventricular pressures during diastole. Echocardiography was performed on all patients, measuring left ventricular volumes at the beginning and end of ...

Diagnostic cardiac catheterization was performed within 2 h after echocardiography. Before contrast material was injected into the LV or coronary artery, LV pressure was obtained using a catheter-tipped micromanometer (SPC-454D, Millar Instrument Co., Houston, Texas) and recorded on a polygraph system (RMC-2000, Nihon Kohden Inc., Tokyo, Japan) and also on a digital data recorder (NR-2000, Keyence, Osaka, Japan). The offset of pressure waves obtained using a catheter-tipped micromanometer was adjusted to that obtained using a fluid-filled system. From the recorded pressure waves, the peak negative first derivative of left ventricular pressure (dP/dt) was determined, and then Tw was calculated using the method proposed by Weiss et al. (18). In the calculation of Tw, the following assumption is applied: a monoexponential curve fitting with LV pressure decay after the phase of peak negative dP/dt has a zero asymptote. This assumption may bring a possibility that Tw is dependent on LV contraction ...
Background: In assessing left ventricular (LV) end-diastolic pressure (EDP) noninvasively, not only left atrial (LA) function but also LV compliance should be considered. Recently developed tissue strain imaging (TSI) enables us to evaluate myocardial extensibility during diastole. Accordingly, we investigated whether LVEDP could be predicted using a new parameter, ie, LA dimension at LV end-systole (LADs) corrected by LV diastolic myocardial strain (%thinning from end systole).. Methods: Study subjects consisted of 112 patients collected from our data base of 322 patients underwent TSI and diagnostic cardiac catheterization on the same day. In all patients, leftventriculography and LVEDP measurement were performed. Fifty-six had prior myocardial infarction (MI). Thirty-nine were anterior MI, 11 inferior and 6 were anterior plus inferior wall MI. Fourteen of those had a LV apical aneurysm. The remaining 56 had no localized LV wall motion abnormality. Peak radial strain during early diastole ...

Non-pharmacological interventions to reduce psychological distress in patients undergoing diagnostic cardiac catheterization: a rapid review
The cardiac catheterization procedure takes between 30 minutes to an hour. You will not be completely asleep during the procedure, because it will be necessary to talk to you during the test. There will be several staff members in the lab that will assist the physician. A Coronary angiography is usually done along with cardiac catheterization. A Coronary Angiogram is a test that uses X-rays to help your doctor find narrowing or blockage in one or more of your coronary arteries. To perform an angiogram, your physician will numb your groin with medicine, The medicine may burn as it begins to work but then you should have no pain for the rest of the exam. A small thin tube called a catheter will be threaded through a large vessel in your leg known as the femoral artery. It will follow that artery to your heart. Some physicians have been specially trained to use the wrist (radial) artery, which is possible in certain patients and has an advantage of speedier recovery. Because catheters and devices ...

Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. This is done both for diagnostic and interventional purposes. Subsets of this technique are mainly coronary catheterization, involving the catheterization of the coronary arteries, and catheterization of cardiac chambers and valves of the cardiac system. "Cardiac catheterization" is a general term for a group of procedures that are performed using this method, such as coronary angiography and left ventricle angiography. Once the catheter is in place, it can be used to perform a number of procedures including, coronary angioplasty, balloon septostomy, electrophysiology study or catheter ablation. Procedures can be diagnostic or therapeutic. For example, coronary angiography is a diagnostic procedure that allows the interventional cardiologist to visualize the coronary vessels. Percutaneous coronary intervention, however, involves the use of mechanical stents to increase blood flow to ...
Cardiac Catheterization is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart.

Blockages prevent your heart from getting oxygen and important nutrients. This procedure is used to diagnose coronary heart disease and coronary microvascular disease after chest pain, sudden cardiac arrest, or abnormal results from tests such as an electrocardiogram (EKG) of the heart or an exercise stress test. It is important to detect blockages because over time they can cause chest pain, especially with physical activity or stress, or a heart attack. If you are having a heart attack, coronary angiography can help your doctors plan your treatment.. Cardiologists, or doctors who specialize in the heart, will perform coronary angiography in a hospital or specialized laboratory. You will stay awake so you can follow your doctors instructions, but you will get medicine to relax you during the procedure. You will lie on your back on a movable table. Often, coronary angiography is done with a cardiac catheterization procedure. For this, your doctor will clean and numb an area on the arm, groin or ...

There are ,400,000 percutaneous transluminal coronary angioplasty (PTCA) procedures performed each year in the United States, at an estimated cost of 6 billion dollars ([1]). Health care providers are under intense pressure from third-party payers to reduce the cost associated with PTCA ([2]). One proposed cost reduction strategy is to perform PTCA at the time of the initial diagnostic catheterization ("combined," "ad hoc" or "add-on" procedures [[3, 4]]). Along with the potential for decreasing length of hospital stay and costs ([3]), these "combined" PTCAs may also reduce the risk of peripheral vascular complications and patient exposure to radiation and contrast agents ([3]).. However, the potential benefits of performing combined procedures must be weighed against their possible risks. Performing PTCA immediately after a diagnostic procedure involves prolongation of the catheterization procedure and may not allow for as careful an assessment of the indications for or technical difficulty of ...

Invasive cardiology. Cardiovascular technologists specializing in invasive procedures are called cardiology technologists. They assist physicians with cardiac catheterization procedures in which a small tube, or catheter, is threaded through a patients artery from a spot on the patients groin to the heart. The procedure can determine whether a blockage exists in the blood vessels that supply the heart muscle or help to diagnose other problems. Some of these procedures may involve balloon angioplasty, which can be used to treat blockages of blood vessels or heart valves without the need for heart surgery. Cardiology technologists assist physicians as they insert a catheter with a balloon on the end to the point of the obstruction. Catheters are also used in electrophysiology tests, which help locate the specific areas of heart tissue that give rise to the abnormal electrical impulses that cause arrhythmias ...

How is Right Heart Catheterization abbreviated? RHC stands for Right Heart Catheterization. RHC is defined as Right Heart Catheterization frequently.
The first long-lasting, widely used application of diagnostic cardiac ultrasound was the detection of pericardial effusion. Although cardiac ultrasound already had been around for at least 10 years, one can make a strong case that this use of cardiac ultrasound was the real origin of todays practice of echocardiography (echo). This particular application all came about because of an erroneous advertisement.. In 1963, I was in charge of our cardiac catheterization laboratory. From an investigational point of view, I was interested in left ventricular function. I was specifically interested in the status of the left ventricle in patients with mitral stenosis (1). Although the left ventricle was thought to be totally normal with mitral stenosis, we had data indicating that the diastolic function was abnormal. As a result, we were studying the left ventricular pressure volume relationship during diastole at rest and with exercise. There were definite limitations to the techniques we were using. I ...
Susanne Ohlhorst, educated as a Master in Nursing science from the University Hospital in Zürich, Switzerland, gave an excellent overview on the problems encountered with the use of an indwelling catheter. One of her main messages in case of indications for indwelling catheters was to use intermittent catheterisation, postoperative, instead of indwelling catheterisation, whenever possible!. She underscored the complications of catheterisation and said that around 30% of all patients with short-term catheters have urinary tract infections (UTI). UTIs account for 30% of all hospital-acquired infections. Leakage occurs in 11% and urethral strictures and erosions between 3% and 17% (Hollingsworth, 2013).. The complications of long-term catheterisation are described as follows: One UTI per 100 catheter days.. Patients with indwelling catheters are three times more likely to die, to be hospitalised or to require antibiotics. Urosepsis often follows on a traumatic manipulation of the indwelling ...

Approach and Results-We performed a cross-sectional study using 2124 individuals residing in North Carolina, United States, who received a cardiac catheterization at the Duke University Medical Center. Traffic-related exposure was assessed via 2 metrics: (1) the distance between the primary residence and the nearest major roadway; and (2) location of the primary residence in regions defined based on local traffic patterns. We examined 4 cardiovascular disease outcomes: hypertension, peripheral arterial disease, the number of diseased coronary vessels, and recent myocardial infarction. Statistical models were adjusted for race, sex, smoking, type 2 diabetes mellitus, body mass index, hyperlipidemia, and home value. Results are expressed in terms of the odds ratio (OR). A 23% decrease in residential distance to major roadways was associated with higher prevalence of peripheral arterial disease (OR=1.29; 95% confidence interval, 1.08-1.55) and hypertension (OR=1.15; 95% confidence interval, ...

In cardiac catheterization (often called cardiac cath), a very small hollow tube, or catheter, is advanced from a blood vessel in the groin or arm through the aorta and into the heart. Once the catheter is in place, several diagnostic techniques may be used. The tip of the catheter can be placed into various parts of the heart to measure the pressures within the chambers and how much oxygen is in the blood. Its also used to get information about the pumping ability of the heart muscle. The catheter can be advanced into the coronary arteries where a contrast dye can injected into the arteries. The use of fluoroscopy (a special type of X-ray, similar to an X-ray "movie") assists our physicians in the location of blockages in the coronary arteries as the contrast dye moves through the arteries.. Cardiac catheterization is a medical procedure used to diagnose and treat some heart conditions, including:. ...
X-ray catheterization is used to guide minimally invasive procedures including percutaneous coronary interventions (PCIs), involving diffuse and multiple vessel disease and total chronic occlusion as well as electrophysiology (EP) procedures. While the medical benefit to patients outweighs the procedural risk, long fluoroscopy times associated with complex interventions have resulted in acute radiation injuries to patients. Radiation induced cancers have also become a concern in younger patient populations. With the increased number, diversity and complexity of the interventions performed, there has been a growing interest in reducing the long-term exposure risk to medical personnel (interventionists).. Conventional methods to reduce in radiation exposure, however, impact and often degrade diagnostic image quality. Catheterization procedures focus on a small portion of the anatomy forming the central region of the image with the periphery providing contextual information. Thus, decreasing the ...
The medical record review for Patient # 9 was completed on 09/20/12. This patient sent a letter of complaint to the hospital, initially on 03/29/12. The complainants letter alleged that a cardiac catheterization and stent insertion was done, on 10/20/11, without the patients consent. The hospital first received the complaint letter from the complainant on 04/03/12. One of the nine hospital ombudsmen was assigned the case, and the investigation began. The ombudsman interviewed the four physicians involved, the physician who obtained the consent and the three involved in the catheterization procedure directly. The ombudsman also interviewed one of the two nurses in the room during the patients catheterization. In accordance with hospital procedure, the ombudsman made two attempts to call the complainant and left voice messages due to inability to reach the complainant. Because the ombudsman could not reach the complainant by phone, a letter was sent on 04/11/12 asking the complainant to call ...
Left heart catheterization allows for direct intervention in cases of coronary artery occlusion. This technique is also used to assess the amount of occlusion (or blockage) in a coronary artery, often described as a percentage of occlusion. A thin, flexible wire is inserted into either the femoral artery or the radial artery and threaded toward the heart until it is in the ascending aorta. Radial access is not associated with an increased risk of stroke over femoral access.[7] At this point, a catheter is guided over the wire into the ascending aorta, where it can be maneuvered into the coronary arteries through the coronary ostia.[5] In this position, the interventional cardiologist can inject contrast and visualize the flow through the vessel. If necessary, the physician can utilize percutaneous coronary intervention techniques, including the use of a stent (either bare-metal or drug-eluting) to open the blocked vessel and restore appropriate blood flow. In general, occlusions greater than 70% ...

Cardiac catheterization, also known as a coronary angiogram, allows cardiologists to see how well the heart is functioning. The insertion of a catheter into the chamber or vessel of the heart can be done for both investigational and interventional purposes. The clinical application of this procedure dates back to the early 1930s and, to this day, has continued to provide doctors the insight needed to save or improve the lives of their patients.. This invasive imaging procedure tests for heart disease and other related complications that otherwise could not have been examined in such detail. A long, thin, flexible tube is inserted into a blood vessel in your groin, arm, or neck. For a more detailed diagnosis, the doctor will then put a special dye into the catheter which will travel through the bloodstream, into your heart and allow for a clear, detailed x-ray to be taken of the arteries.

Intravascular ultrasound (IVUS) is the most favorable imaging modality that often used in coronary artery catheterization procedures and provides cross-sectional images of arterial wall structures and extend of atherosclerosis disease. Although several techniques have been developed to classify atherosclerotic tissues, deploying IVUS radiofrequency (RF) backscattered signals and/or grayscale images their clinical applications have seen limited success. In this paper, we propose a unified methodological framework from data collection, histology preparation, registration, feature extraction, and classification to achieve a reliable in vitro trained tissue characterization classifier for in vivo applications. Finally, the results from proposed algorithm is compared with state of the art virtual histology (VH) technique ...

Created exclusively for patients recovering after the radial catheterization procedure, the radial lounge differs from traditional recovery rooms in that it is intentionally designed to depart from a clinical environment by offering the patient a less stressful atmosphere. Here, they can relax in recliners, have something to eat, or watch television. Patients are not restricted to complete bed rest.. Thats where Neutze recovered after his second procedure. "The radial lounge was great. It has recliner chairs and a refrigerator stocked with food and drinks, which was nice because I had to fast before the procedure. My wife was able to join me and there is a large seating area for visitors in front of a big-screen TV," he notes. "Once they took my IV out, I could get up and walk around. The nurse who cared for me was wonderful and I felt much more relaxed. It was very comfortable.". Transradial access is slowly gaining ground in the United States. Currently, about 30 to 40 percent of ...

The importance of displaying and recording multiple superimposed channels of physiologic signals was rapidly recognized. Thus, the first major development was the move from ink-writing oscillographs to multichannel oscilloscopic recorders. These instruments could display multiple channels of physiologic signals in real time on an oscilloscopic screen. The physician operator could view the screen in order to monitor in real time both the data being obtained and the patients condition. These instruments also added an important adjunct-the ability to superimpose multiple analog signals in a time-based display. This capability enhanced signal interpretation by displaying the nuances of relationships between different signals. (eg, superimposing pressure signals from adjacent cardiac chambers facilitates the recognition and measurement of pressure gradients.) This capability required incorporating photo-optical recorders that could record the individual superimposed oscilloscopic beams on ...

Transradial catheterization is an endovascular procedure or catherization procedure performed to diagnose and treat arterial disease (e.g., coronary artery disease, peripheral artery disease, etc.). Endovascular procedure can be performed achieving access in to bodys arterial system from either femoral artery (in groin), brachial artery (in elbow) or radial artery in the wrist. The transfemoral (through groin) approach to perform cardiac catheterization has typically been more prevalent in invasive cardiology. But, radial access has gained in popularity due to technical advances with catheters and lower complication rates than transfemoral access. In 1948, Radner published one of the first descriptions of transradial central arterial catheterization and attempts at coronary artery imaging using radial artery cut-down. Transradial access to perform diagnostic cardiac catheterization procedures was introduced by Campeau and was later adapted for therapeutic procedures of coronary angioplasty by ...
Cardiac catheterisation in patients on extracorporeal membrane oxygenation (ECMO) may reveal new information leading to modification of a therapeutic plan and correction of newly recognised or residual lesions. Complications associated with cardiac catheterisation during ECMO are not uncommon and often related to the access site. We report a straightforward technique for accessing the ECMO circuit to perform an emergent cardiac catheterisation in two patients with hypoplastic left heart syndrome decompensated after Norwood I, due to presumed systemic-to-pulmonary artery shunt obstruction ...
BACKGROUND New generation transcatheter heart valves (THV) may improve clinical outcomes of transcatheter aortic valve implantation. METHODS AND RESULTS In a nationwide, prospective, multicenter cohort study (Swiss Transcatheter Aortic Valve Implantation Registry, NCT01368250), outcomes of consecutive transfemoral transcatheter aortic valve implantation patients treated with the Sapien 3 THV (S3) versus the Sapien XT THV (XT) were investigated. An overall of 153 consecutive S3 patients were compared with 445 consecutive XT patients. Postprocedural mean transprosthetic gradient (6.5±3.0 versus 7.8±6.3 mm Hg, P=0.17) did not differ between S3 and XT patients, respectively. The rate of more than mild paravalvular regurgitation (1.3% versus 5.3%, P=0.04) and of vascular (5.3% versus 16.9%, P,0.01) complications were significantly lower in S3 patients. A higher rate of new permanent pacemaker implantations was observed in patients receiving the S3 valve (17.0% versus 11.0%, P=0.01). There were no ...
Degenerative aortic stenosis is the most prevalent aortic valve disease in western countries. Ageing processes and increased life expectancy of the population increase the prevalence of this valvular heart disease.w1 Surgical aortic valve replacement is the first therapeutic option for patients with severe symptomatic aortic stenosis. However, in selected subgroups of patients, the operative risk may outweigh the clinical benefits of surgery. Older age, severe left ventricular systolic dysfunction, and associated comorbidities such as neurological diseases are the main determinants of non-referral for surgery in almost 30% of patients with severe symptomatic aortic stenosis.w2. Technological advances in the field of percutaneous cardiovascular interventions have favoured the development of less invasive therapeutic strategies. The emerging transcatheter aortic valve implantation (TAVI) techniques have been shown to be a feasible alternative to surgical aortic valve replacement.w3 To date, ,40 ...
A 78-year-old woman with chest discomfort and progressive exertional dyspnea was admitted to our center. Transthoracic echocardiography (TTE) suggested severe aortic stenosis (AS) (mean pressure gradient 70 mm Hg; peak jet velocity 5.4 m/s) and moderate aortic regurgitation (AR). Left ventricular ejection fraction was 64%. Bicuspidy of the aortic valve and aneurysmal dilation of the ascending aorta (56 mm in diameter) were noted on TTE. She was declined for surgery on account of high operative risk (logistic EuroSCORE 31.67%) after consultations by the heart team, thus she was evaluated for transcatheter aortic valve implantation (TAVI). Coronary angiogram showed the absence of significant coronary lesions. Three-dimensional computed tomographic angiography (CTA) confirmed the bicuspidy (Fig. 1A) and measured the diameter of the ascending aorta at 53 mm (Fig. 1B); the annulus was elliptical with a long-axis diameter of 25.6 mm and a short-axis diameter of 19.5 mm. TAVI was conducted in a hybrid ...
New conduction defects develop in as many as one-third of patients undergoing surgical replacement of the aortic valve, with LBBB being the most common abnormality (18-20). After TAVI, new conduction defects have been described in an even significantly higher number of patients, with new LBBB being the predominant new conduction defect (7-11,21-24). The anatomic neighborhood of the aortic valve to the atrioventricular bundle; degeneration of the conduction system; trauma by guidewires, catheters, and pre-implantation balloon valvuloplasty; and direct constant pressure of the implanted valve on the left bundle branch at the base of the interleaflet triangle between the right and noncoronary triangle are the potential causes (25). The frequency of new LBBB has been reported to be higher after implantation of the CoreValve prosthesis as compared with the Edwards SAPIEN prosthesis (24). This has been explained by the larger size of the CoreValve prosthesis and, in particular, the greater depth of ...
Repair of the Transcatheter aortic valve is a minimally invasive procedure. This technique is used without removing it to treat or restore old and damaged aortic valve. The technique used to insert a new valve to the place of the old aortic valve is called the Transcatheter aortic valve replacement system. Between the left atrium and the left ventricle is the mitral valve. Mitral valve disorder is a condition in which the valve ceases working properly, leading to abnormal blood flow. This abnormal blood flow can lead to diseases such as prolapse of the mitral valve and regurgitation of the mitral valve.. Renub Research latest study report "Transcatheter Heart Valve Replacement Market, Volume, Share by Materials (Mechanical and Tissue) Position (Transcather Mitral Valve Replacement and Transcatheter Aortic Valve Replacement), Region (United States, Germany, China, France, Italy, Japan, Spain, United Kingdom, India and Brazil), Company Analysis" provides a detailed and comprehensive insight of the ...
The left ventricular apex has excellent accessibility to the aortic valve, mitral valve, left ventricular outflow tract and thoracic aorta. Although the number of transapical approach in transcatheter aortic valve replacement has been decreasing in recent years, it is still a useful option for patients with very poor peripheral vascular access. The apex has been chosen as a primary access site for many devices of transcatheter mitral valve repair/replacement and mitral valve-in-valve procedures. Additionally, the transapical approach has been used for other transcatheter cardiovascular interventions such as paravalvular leak repair after mitral or aortic valve replacement, pseudoaneurysm repair of the left ventricular outflow tract, and thoracic endovascular aortic repair ...
