BACKGROUND: Left ventricular thrombus is a common complication after acute myocardial infarction. Methods and RESULTS: To Study the incidence of left ventricular thrombosis (LVT) after acute myocardial infarction, we performed serial two-dimensional echocardiography (2D-Echo) in 35 consecutive patients with acute myocardial infarction prospectively ; 10 patients had inferior wall myocardial infarction, 25 patients had anterior wall myocardial infarction. 2D-Echo was obtained within 3 days of acute myocardial infarction, at 4-10 days after symptom onset, and 2-4 weeks after symptom onset serially in each case. 19 out of 35 patients received thrombolytic therapy with urokinase. Left ventricular thrombi were identified in 9(25.7%) of the 35 study patients. The location of myocardial infarction was anterior and apical in all cases with left ventricular thrombi. The shape of thrombi was mural in 6 cases and protruding in 3 cases. The incidence of left ventricular thrombi in patients who received urokinase was not significantly different from that in patients who didn't(31.9% vs 18.8%,p=0.22). Wall motion score was significantly higher in patients who developed left ventricular thrombi than in patients who had no left ventricular thrombus(8.2+/-1.9 vs 5.8+/-2.6, p<0.005). All thrombi appeared within 10 days after myocardial infarction. CONCLUSIONS: Thus left ventricular thrombi develops within 10 days following myocardial infarction with large anterior and apical location. The thrombolysis therapy has no effect in the incidence of left ventricular thrombi in this study. But because of confounding effect of thrombolysis and location of myocardial infarction and extent of myocardial infarction, further investigation is needed.

The incidence of otogenic intracranial complication has decreased markedly following the advent of modern chemotherapy. Less is it a disease of children in association with acute otitis media. More often it is seen in the adult after a long history of chronic ear disease, especially cholesteatoma. In the modern literature on lateral sinus thrombosis, meningitis and cerebral abscess are listed as the most common concomitant complications and cerebellar abscess is poorer prognosis than any other complications. Recently we experienced a case of cerebellar abscess after treatment of lateral sinus thrombophlebitis associated with cholesteatoma, and reported this case along with literature survey.

To evaluate the feasibility and usefulness of transthoracic Doppler echocardiography (TTDE) as a non-invasive method in recording distal anterior descending (LAD) coronary flow velocity, we compared coronary flow reserve (CFR) measured by TTDE with measurements by intracoronary Doppler wire (ICDW). Twenty-one patients without LAD stenosis were studied. ICDW performed at baseline and after intracoronary injection of 18 microg adenosine. TTDE was performed at baseline and after intravenous adenosine (140 microg/kgmin for 2 min). Adequate Doppler recordings of coronary flow velocities during systole were obtained in 14 of 21 study patients (67%) and during diastole in 17 (81%) patients. Baseline and hyperemic peak diastolic flow velocities measured by TTDE were significantly smaller than those obtained by ICDW (p<0.05). However, diminishing trends of diastolic and systolic velocity ratio after hyperemia were similarly observed in both methods. CFR obtained by TTDE (3.0+/-0.5), was higher than the value calculated by ICDW (2.5+/-0.4). There were significant correlations between the values obtained by the two methods (r=0.72, p<0.01). It is concluded that TTDE is a feasible method in measuring coronary flow velocity and appears to be a promising non-invasive method in evaluating CFR.

BACKGROUND AND OBJECTIVES: Arrhythmia is known to be a major cause of death in acute myocardial infarction (AMI). Reperfusion arrhythmias (RA) may also occur during angioplasty or thrombolysis. As yet, the clinical significances of RA and angiographic characteristics of the patients who develop RA during primary angioplasty and stenting are not clearly defined. METHODS: The study group consisted of 60 patients treated with primary angioplasty or stenting for AMI (angioplasty 13, stenting 47 patients). The patients were classified into 2 groups according to RA [RA (-) N=36/RA(+) N=24]: demographic and angiographic characteristics including time to reperfusion and incidence of pre-infarct angina were analyzed. RESULTS: The RA occurred in 40% of patients undergoing primary angioplasty or stenting (24/60 patients). The minor arrhythmias were more common after reperfusion (transient bradycardia 14, accelerated idioventricular rhythm 11, premature ventricular contraction 4 cases): major arrhythmias were uncommon (ventricular tachycardia/fibrillation 5, asystole 1 case). In the two groups, baseline clinical characteristics were similar except for pain to reperfusion time [RA (-): RA (+)=490.8+/-291.7: 252.9+/-109.2 minutes, P=0.001]. There was a trend toward a greater incidence of RA in the right coronary infarct-related artery [RA (-): RA (+)=16.7: 41.7%, P=NS]. The RA occurred in totally occluded artery (TIMI 0) with a giant thrombus and first ballooning in 19/24 patients (79.2%). The RA disappeared with conservative managements including pacemaker insertion and cardiopulmonary resuscitation and there were no differences in major adverse cardiac events in the two groups during follow-up. CONCLUSIONS: These findings suggest that the RA are frequent events during primary angioplasty but unrelated to clinical and angiographic characteristics except for reperfusion time and do not influence short-term prognosis in AMI.

BACKGROUND AND PURPOSE: Left ventricular hypertrophy (LVH) is a well known cardiovascular risk factor, independent of hypertension, even in the absence of epicardial coronary artery disease. Possible mechanisms have been proposed, including increased LV mass, reduced coronary flow reserve (CFR) and diastolic filling abnormalities. However, the relations among LV hypertrophy, diastolic function, hypertension and coronary flow reserve (CFR) in patients with chest pain and normal coronary angiograms have not been well defined. SUBJECTS AND METHOD: Twenty-six patients with chest pain and normal coronary angiograms were included. LV mass, isovolumic relaxation time (IVRT), deceleration time (DT) and E/A ratio were assessed by 2-D echo-cardiography. Coronary blood flow velocity before and after intracoronary adenosine were measured using intracoronary Doppler wire (FIoWire). CFR was defined as ratio of peak flow velocity after adenosine to baseline flow velocity. Subjects were devided into 4 groups according to presence of LVH and hypertension and the parameters were compared among groups. RESULTS: FR was lower (p<0.01) in the groups with either hypertension or LVH or both than in the groups without them. The decrement in CFR was not linearly related to the degree of LVH (r=0.31, p=0.135). Although there were modest increment in IVRT and DT and decrement in E/A ratio in the groups with hypertension or LVH or both, there was no statistical significance. CONCLUSION: These findings suggest that the underlying mechanism of impaired CFR in patients with LVH or hypertension may be the consequence of primary coronary microvascular lesion rather than the process of left ventricular hypertrophy.

OBJECTIVE: Multiple typologies of alcoholics have been studied, such as Jellineck's disease concept classification, Cloninger's neurobiological learning model, Bucker's developmental model, DSM III-B and DSM IV classification, and Babor's multidimensional typology. To study if Babor's typology modification could be used to classify Korean alcoholics, we grouped 95 male inpatient alcoholics into Babor's typology modification. METHODS: This study employed cluster analysis of measures representing several dimensions premorbid risk and vulnerability dependence severity and alcohol-related problems, chronicity and alcohol-related consequences, and comorbid psychopathology. We compared demographic and clinical characteristics among Babor's type A and type B alcoholics and normal control group. RESULTS: Type B alcoholics showed more characteristic symptoms in family history, more childhood behavior problems, earlier onset, more drinking amount, and more dependence severity, more medical, social, physical problems, more life time severity, more depressive, anxiety, hostility, compared with type A alcoholics. The statistically significant variables differentiating three groups(type A, type B, normal control group) were drinking days, dependence severity, lifetime severity, medical, social consequence. Alcohol Use Inventory to Babor s typology of alcoholism was very useful scale differentiating three groups. CONCLUSION: Babor's typology of alcoholism was useful for classification of inpatient alcoholics of Korea. It can be helpful and applicable to clinical diagnosis and research in Korean alcoholic patients.

PURPOSE: To determine the usefulness of microbubble contrast enhanced power Doppler ultrasonography (PDUS)for the detection of residual tumor in hepatocellular carcinomas (HCCs) treated by transcatheter arterialchemoembolization (TACE). MATERIALS AND METHODS: Fourteen nodular HCCs (size range: 1 - 7.3 cm, mean: 3.5) intwelve patients treated by TACE, and on the basis of follow-up liver CT, thought to have a residual tumor, wereincluded in this study. Between July 1997 and April 1998, PDUS examinations were performed with a 2-4 MHz convextransducer before and after intravenous injection of a microbubble contrast agent (Levovist(, Schering AG, Berlin,Germany). Real-time power Doppler ultrasonographic images were recorded on videotape and representative imageswere color-printed. Tumor vascularity was analyzed on real-time images with regard to its presence or absence, andchanges, and two observers reached a consensus. The results were compared with those of other diagnostic tests(three-phase helical CT, conventional angiography, percutaneous biopsy, and/or surgical pathology). RESULTS: Contrast-enhanced PDUS revealed intratumoral vascularity in ten of 14 tumors, none of which showed vascularity onunenhanced PDUS. In the remaining four tumors, both unenhanced and enhanced PDUS showed intratumoral tumorvascularity, which in all cases was more pronounced on enhanced than on unenhanced PDUS. Other diagnostic testsrevealed residual tumors in eleven lesions. CONCLUSION: Microbubble contrast-enhanced PDUS was more sensitivethan non-enhanced PDUS in depicting vascularity within a residual tumor and could be a useful method for thedetection of residual tumor in HCCs treated by TACE.

BACKGROUND: The presence of diastolic mitral regurgitation has been described in patients with complete atrioventricular(AV) block, aortic valve regurgitation, hypertrophic and restrictive cardiomyopathy, and in patients with long diastolic filling period in atrial fibrillation. However, because of rare incidence and difficulty in making diagnosis of this phenomenon, the frequency and hemodynamic effects of diastolic AV valve regurgitation(DAVVR) and relationship of electrocardiographic(ECG) parameters with DAVVR in patients with complete heart block have not been reported in Korea. METHODS: To evaluate the frequency, hemodynamic effects of DAVVR and relation of ECG parameters with DAVVR in patients with complete AV block, we studied 14 consecutive patients with complete AV block by means of two dimensional and Doppper echocardiography. RESULTS: The DAVVR was observed in all cases of complete AV block except 3 cases on temporary pacemaker. The peak velocy of diastolic mitral and tricuspid valve regurgitaton were 105+/-23cm/sec and 98+/-30cm/sec, respectively. The peak and mean pressure gradient of diastolic mitral regurgitation were 4.7+/-1.7mmHg and 3.1+/-1.5mmHg respectively, and the peak and mean pressure gradient of diastolic tricuspid regurgitation were 4.1+/-2.6mmHg and 2.7+/-2.1mmHg, respectively. There was regular interval between p-wave of ECG and onset of diastolic AV valve regurgitation, which was 215+/-12msec, Diastolic AV valve regurgitation disappeared immediately after recovery of complete AV block to sinus rhythm or insertion of DDD-type permanent pacemaker in all cases. CONCLUSION: In Conclusion, the DAVVR was observed in all cases of complete AV block except cases on temporary pacemaker insertion and its hemodynamic effect was mild. There was regular interval between p-wave of ECG and the onset of diastolic AV valve regurgitation.

BACKGROUND: Although determination of Doppler echocardiographic transmitral inflow patterns(DETIP) is used as an indrect method assessing LV diastolic function. It is known that DETIP can be affected by certain hemodynamic variables. The aim of this investigation is to assess the serial changes of DETIP and to determine the relation of DETIP with clinical parameter such as initial left ventricular end-diastolic volume(LVEDV), ejection fraction(EF), Killip class and thrombolytic therapy in acute myocardial infarction (AMI) patients. METHOD: Four serial Doppler and 2-D echocardiographic studies were performed at 1 day, 1 week, 1mouth, and 3 months after development of AMI in 24 patients(M:F=19:5, aged 58+/-11 year , 15 anterior MI) and 13 normal adults (aged 47+/-9 years) as reference group. On admission 14 patients were in Killip class I and 10 patients in class II. Thrombolytic therapy with IV urokinase were done in 11 patients. E velocity, pressure half-time (PHT), and isovolumic relaxation time(IVRT) were analyzed and LV systolic function was determined in apical 4 chamber view. RESULTS: DETIP did not change until 1month after development of AMI. However, E/A ratio was decreased, and PHT and IVRT were increased at 3 months after AMI. Doppler transmitral flow parameters were not related with Killip class and LV systolic function. Patiens who recieved urokinase intravenously and who had greater intial LVEDV(>118cm3) showed higher E/A ratio and shorter PHTand IVRT than those who did not. These findings indicate that changes in Doppler transmitral inflow pattern in AMI patients are not uniform over a period of 3 months and thrombolytic therapy causes favorable effect on Doppler transmitral flow parameters. CONCLUSION: Changes in Doppler trasmitral inflow pattern may be variable over post-AMI period and this should be taken into account in evaluating LV diastolic function after AMI. Thrombolytic therapy may improve LV diastolic function in AMI patients.
