1/26. Multislice cardiac spiral CT evaluation of atypical hypertrophic cardiomyopathy with a calcified left ventricular thrombus.We report a case of a 43-year-old male patient with an atypical nonobstructive hypertrophic cardiomyopathy and a calcified left ventricular thrombus, and present results of multislice computed tomography (MSCT) using retrospective electrocardiograph gating, which is a new modality in cardiac imaging. Obtaining virtually motion-free images with a temporal resolution of 250 ms in an optimized heart scan MSCT allows functional imaging with evaluation of impaired systolic and diastolic left ventricular wall motion.- - - - - - - - - - ranking = 1keywords = motion (Clic here for more details about this article) |
2/26. Primer on cardiac magnetic resonance imaging: how to perform the examination.Cardiac magnetic resonance imaging is made possible by utilizing an external signal, the patient's own electrocardiogram, to time image acquisition. ECG gated cardiac magnetic resonance examination may be performed using spin-echo or gradient reversal techniques or their newer k-space segmented variants. Spin-echo techniques provide the highest contrast between rapidly moving blood and the cardiac chambers and arteries and veins containing the blood, but are of relatively low temporal resolution. Gradient reversal acquisition, however, provides higher temporal resolution ideal for evaluating changes in myocardial thickening, ventricular wall motion abnormalities, and changes in chamber volume through the cardiac cycle; gradient reversal technique has significantly lower contrast resolution. Careful attention to the details of image acquisition will provide high-quality images of the heart and great arteries from which important morphologic and physiological information may be obtained, aiding in the diagnosis and management of patients with cardiovascular disease.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
3/26. Paradoxical motion of the interventricular septum in a patient with normal right heart hemodynamics.A 32-year-old man with paradoxical motion of the interventricular septum at the level of the chordae tendineae and with normal right heart hemodynamics is presented. It appears that, in absence of severe left ventricular dysfunction or intraventricular conduction defect, paradoxical septal motion is not entirely specific for right ventricular volume overload and may represent a rare normal variant.- - - - - - - - - - ranking = 3keywords = motion (Clic here for more details about this article) |
4/26. Emotion and cardiac technology: an interpretive study.This paper presents a frequently overlooked aspect of advanced technological care--that of the human dimension and emotions. Emotionality is defined as the emotional ways that a client experiences their embodied experience as a recipient of a cardiac pacemaker. One individual's story from a larger interpretive study of clients who received pacemakers is presented and interpreted. Kev's story encapsulates the difficulties of dealing with and understanding cardiac technology. When Kev's heart malfunctions he confronts a new reality; an experience where the 'technological body' is linked confusingly with emotion. This complex interplay between technology, the body and emotionality is discussed to demonstrate the importance of the mediating role that nurses can and should play in clients' adaptation and recovery.- - - - - - - - - - ranking = 4.5keywords = motion (Clic here for more details about this article) |
5/26. Left ventricular apical thrombus formation in a patient with suspected tako-tsubo-like left ventricular dysfunction.A 74-year-old woman with hypertension and bronchial asthma had chest discomfort at rest and 4 days later was admitted to her nearby hospital because of the sudden onset of right hemiparesis. The hemiparesis had almost disappeared within 24 h of onset, but because an electrocardiogram showed sinus tachycardia and diffuse symmetrical T-wave inversion, she was referred for cardiac examination. coronary angiography did not reveal any significant coronary artery stenosis, but left ventriculography revealed severe hypokinesis of the left ventricular apical region, which contained a 4 x 4-mm solid thrombus moving freely with a wavy motion. Moreover, the activity of both protein c and protein s had decreased. The thrombus disappeared after 2 weeks of anticoagulant treatment with warfarin. Her clinical course suggested that the transient cerebral ischemic attack was caused by embolism of the left ventricular thrombus associated with 'tako-tsubo-like left ventricular dysfunction'.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
6/26. Right atrial thrombus migration during echocardiography: a case for urgent intervention.A 65-year-old woman presented with increasing shortness of breath, chest pain and ST-T wave abnormalities on the electrocardiogram suggestive of unstable angina. Cross-sectional echocardiography performed to assess wall-motion abnormality and left ventricular function revealed a pedunculated right atrial thrombus prolapsing into the right ventricle which suddenly dislodged and migrated into the pulmonary circulation during the examination. A diagnosis of recurrent pulmonary thromboembolism was made, necessitating urgent pulmonary angiography with infusion of streptokinase. The patient made an uneventful recovery.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |

This study was conducted to determine the frequency, magnitude, and duration of myocardial dysfunction in such persons. methods: We enrolled 30 previously healthy young adults without known cardiovascular disease who presented to the clinic- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
8/26. Echocardiographic findings in patients with wegener granulomatosis.OBJECTIVE: To describe the spectrum and clinical implications of echocardiographic findings associated with wegener granulomatosis. patients AND methods: We retrospectively reviewed the clinical records and echocardiographic data of consecutive patients with confirmed wegener granulomatosis referred to the echocardiography laboratory during the 21-year period from 1976 through 1997. RESULTS: Of the 85 patients Identified as having confirmed wegener granulomatosis, 73 (86%) were found to have echocardiographic abnormalities. In 26 (36%) of these 73 patients, lesions appeared directly related to wegener granulomatosis. We found regional wall motion abnormalities in 17 (65%) of these 26 patients. Left ventricular systolic dysfunction with decreased ejection fraction was found in 13 patients (50%) and pericardial effusion in 5 patients (19%). Other findings Included valvulitis, left ventricular aneurysm, and a large intracardlac mass. A significantly increased mortality rate was observed among patients who had cardiac involvement of wegener granulomatosis found by echocardiography. CONCLUSIONS: We found a high frequency of echocardiographic abnormalities that appear to be related to wegener granulomatosis and associated with Increased mortality. Because cardiac involvement in wegener granulomatosis often is silent and associated with Increased morbidity and worse prognosis, echocardlographic screening of patients with active wegener granulomatosis may be of clinical value.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
9/26. Surgical treatment for Loffler's endocarditis with left ventricular thrombus and severe mitral regurgitation: a case report.A 65-year-old female was admitted to our hospital because of dyspnea. Laboratory examinations revealed hypereosinophilia at a local hospital. Transthoracic and transesophageal echocardiography showed normal left ventricular dimension and function. The left ventricular apex was obliterated and the posterior and lateral walls were thickened by an abnormal mass. The posterior mitral leaflet was encapsulated by this abnormal mass. The limited motion of the posterior mitral leaflet caused mitral malcoaptation, resulting in severe mitral regurgitation. Hypereosinophilia was considered to be idiopathic, as no other disorders known to cause secondary eosinophilia were found. No other organ dysfunction was associated with the condition. Thus, the diagnosis was Loffler's endocarditis associated with hypereosinophilic syndrome. The patient was given conservative medical treatment immediately on admission. However, heart failure caused by mitral regurgitation would be difficult to treat with conservative medical treatment, so we chose a surgical strategy. The symptoms obviously improved after valve replacement and removal of the abnormal mass, and the patient was discharged. However, she died of cerebral infarction at a local hospital 3 months later.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
10/26. Left ventricular thrombus in a 2-year-old boy with cardiomyopathy: lysis with recombinant tissue-type plasminogen activator.A 2-year-old boy with cardiomyopathy and clinical signs of cardiac failure presented with an echodense structure in the left ventricle. This structure was seen from different echocardiographic views adjacent to a hypokinetic area of the apex and lateral free wall. It was different in texture and motion from the underlying myocardium and thus met the diagnostic criteria of a left ventricular thrombus. This thrombus protruded into the cavum and was partly mobile. In view of a high embolic risk, thrombolytic therapy with recombinant tissue plasminogen activator was started. The thrombus resolved within 72 h without any embolic or bleeding complications. No recurrence of the thrombus was observed during a 3-month follow up period.- - - - - - - - - - ranking = 0.5keywords = motion (Clic here for more details about this article) |
