Limbic bone or persistant epiphysis seen roentgenographically on the anterosuperior aspects of the vertebral bodies represents another form of discal extrusion, seperating a small fragment of bone from the body of the involved vertebra. Lindblom, in 1951, demonstrated the pathophysiology with discography. Anterior herniation of the nucleus pulposus was also revealed by discography by Cloword and Buzaid in 1952. The authors reviewed 3 cases of limbic bone of the vertebrae.

BACKGROUND: To evaluate the efficacy of transesophageal echocardiography(TEE) to detect left atrial thrombi(LAT) and to investigate the clinical and echocardiography parameters which related with LAT. METHOD: We performed TEE and TTE simultaneously to 98 consecutive patients who had native mital valve disease or mital prosthesis as usual method. We examined the presence and location of LAT and spontaneous contrast(SC) in TEE and measured left atrial dimension(LAD), ejection fraction(EF), mital valve area(MVA) in TTE. Cardiac rhythm, history of anticoagulation and systemic embolization were also reviewed. We compared such parameters in LAT positive/negative groups and SC positive/negative groups. RESULTS: 1) In TEE, we detected 26 cases of LAT, among them seventeen cases : left atrial appendage(LAA) thrombi, 3 cases : combined LA and LAA thrombi, 6 cases : LA thrombi. In TTE, six cases showed LAT but we couldn't detect LAA thrombi. The difference between two methods was statistically significant(p<0.05). 2) LAT positive group showed larger LAD, lower EF, and higher prevalence of AF, systemic embolization, and LAT than negative groups(p<0.01). 3) SC positive group showed larger LAD, lower EF, higher prevalence of AF, systemic embolization LAT than SC negative groups(p<0.05). 4) In multiple discriminant analysis, the history of systemic embolization was most important factor which can suspect LAT(Wilk's Lambda:0.77152. p<0.0001). SC, EF, presence of AF, LAD, anticoagulation therapy. MVR were also statistically valuable factors in order. The hit ratio of this analysis was 86.84%. CONCLUSION: We can suggest that TEE is very useful method to detect LAT than TTE, and the spontaneous contrast was very important factor which can suggest LAT and systemic embolization in mitral valve disease.

BACKGROUND: Patients with sinus rhythm, the left atrial appendage(LAA) appeared as a vigorously contracting structure and the blood flow patterns of LAA showed biphasic configuration. However, patients with AF rhythm the blood flow showed irregular or no configuration in doppler echocardiographic study. The purpose of this study is to evaluate relationship between the blood flow patterns of LAA with the presence of spontaneous contrast(SC) and thrombi in LAA. METHODS: We performed TEE and TTE simultaneously to 58 consecutive patients who had native mitral valve disease or mitral prosthesis. Spontaneous contrast(SC) and the presence and location of LAA thrombi were evaluated during TEE and left atrial dimension(LAD) & ejection fraction(EF) were evaluated during TTE. We divided the whole subjects into three groups according to the blood flow patterns ; regular pattern(Group 1), irregular pattern(Group 2), no flow pattern(Group 3). RESULTS: 1) Blood flow within the left atrial appendage is divided with three groups among of them, atrial fibrillation have two blood flow patterns. 2) Peak prositive & negative flow velocity within LAA in AF rhythm groups were slower than normal sinus rhythm group.(p<0.01) 3) Left atrial dimension in group 3 is significantly larger than others groups.(p<0.01) 4) Spontaneous contrast(SC) with LAA could be detected in 2(6.8%) of the 29 patients of group 1, 6(31.5%) of the 19 patients of group 2, 10(100%) of the 10 patients of group 3. Incidence of SC within LAA in group 3 is significantly higher than others groups. 5) LAA thrombi could be detected in 1(3.4%) of the 29 patients of group 1, 1(5.2%) of the 19 patients of group 2, 3(30%) of the 10 patients of group 3. Incidence of LAA thrombi is significangly higher than other groups. CONCLUSIONS: We can suggest that blood flow within LAA is divided into three groups according to the blood flow patterns, and spontaneous contrast and thrombi in LAA were closely related with the blood flow pattern.

BACKGROUND: Although a number of indices of diastolic function based on transmitral flow have been proposed, no single factor seems to be adequate for seperating patients with normal from with abnormal diastolic functions. Pulsed Doppler echocardiography of pulmonary venous flow(PVF) is another non-invasive method to evaluate left ventricular diastolic performance. The purpose of this study is to evaluate the normal PVF pattern by TEE. METHOD: We performed pulsed-wave Doppler studies of the PVF and of the mitral flow by transesophageal-(TEE) and transthoracic echocardiography(TTE) in a healthy young adults. RESULTS: In TEE, all sublects showed four phases of the PVE pattern ; two antewgrade systolic phase(early and late : SE and SL), one antewgrade diastolic phase(D) and one retrograde diastolic phase(A). In TTE, there were three phases of the PVF pattern ; two antewgrade phase(systolic, diastolic) and one retrograde diastolic phase but we couldn't find out early systolic phase flow. Peak velocity of each phase of PVF was as follows:SE was 48.9+/-14.1cm/sec, SL was 56.3+/-16.1cm/sec, D was 52.6+/-14.9cm/sec. The timing of SL flow was correlated significantly with that of peak aortic flow(r=0.42, p=<0.01), while the timing of D flow and that of A flow were correlated significntly with timing of mitral E peak and A peak, respectively(r=0.84, p<0.01 ; r=0.80, p<0.01). CONCLUSIONS: In the young normal subject, PVF showed four phase of flow pattern and could be easily obtained by TEE. Furthermore it may be used for evaluation of left ventricular function.

This study was carried out to determine the accuracy of Doppler echocardiography for predicting the pulmonary arterial pressure from right ventricular systolic time intervals in 52 patients with ventricular septal defect. The diagnosis of ventricular septal defect was made by cardiac catheterization and angiocardiography at Dong San hospital, Keimyung University during the period of one year from jan. 1988 to Dec. 1988. Doppler measurements of acceleration time (AT), right ventricular ejection time (RVET), right ventricular preejection period (RPEP), AT/RVET, and RPEP/AT were compared with pulmonary arterial pressure (PAP), measured by cardiac catheterization. The patients were divided into 3 groups : PAP< or =30mm Hg, PAP 31-59mm Hg, PAP??0mm Hg. The following results were obtained. 1) In the groups of PAP< or =30mm Hg, AT was 0.12+/-0.01sec, AT/RVET was 0.47+/-0.07 and RPEP/AT was 0.50+/-0.05. 2) In the groups of PAP> or =60mm HG, AT was 0.06+/-0.01sec. AT/RVET was 0.28+/-0.05. RPEP/AR was 1.51+/-0.21. As the level of PAP increased, Doppler AT, AT/RVET and RPEP/AT showed significant change(P<0.001). 3) The Doppler AT showed relative high correlation(r=-0.76) with PAP measured by cardiac catheterization in all group. 4) The Doppler AT/RVET showed correlation(r=-0.70) with PAP. 5) The Doppler RPEP/AT showed high correlation(r=0.91) with PAP. The Doppler echocardiography was easy to apply in all age groups, and was found useful for detecting pulmonary hypertension in ventricular septal defect and for the follow-up check of the patients. It may help to determine the optimal time for surgery and evaluation of the treatment.
