The risk factors of abdominal aortic aneurysm (AAA) are old age, atherosclerosis, hypertension, smoking and family history of AAA. And the risk factors of aortic dissection are old age, atherosclerosis, hypertension and other aortic diseases such as aortic aneurysm, coarctation of aorta, aortic arteritis and bicuspid aortic valve. Although AAA and aortic dissection shares common risk factors, combination of these two disease are very uncommon. We report a case of 69-year-old female presented with chronic ascending aortic dissection combined with infrarenal AAA with a diameter of 7 cm and a case of 73-year-old-male presented with intramural hematoma of descending thoracic aorta combined with infrarenal AAA with a diameter of 6 cm.

Primary tumors of the heart are rare, three-quarters of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, but, only 3 to 4 percent of myxoma are detected in the left ventricle. Cardiac myxoma is histologically benign, but may be lethal because of their position. We reported a case of 65-year-old man with left atrium myxoma associated with inferior vena caval thrombi and pulmonary embolism. After the operation of myxoma, the Budd-Chiari syndrome developed and the patient died due to hepatic failure.

Journal of the Korean Society of Echocardiography.2003;11(2):108-113.

Isolated noncompaction of the left ventricular myocardium is a rare cardiac disorder due to an arrest in myocardial morphogenesis. It is characterized by prominent and excessive trabeculation in a ventricular wall segment, with deep intertrabecular spaces perfused from the ventricular cavity. Echocardiographic findings are important clues for the diagnosis. Clinical symptoms include signs of left ventricular systolic dysfunction even to the point of heart failure, ventricular arrhythmias, and embolic events. We describe two cases of isolated noncompaction of the myocardium, with ventricular tachycardia in one, and chest pain due to microvascular dysfunction in the other.

Journal of the Korean Society of Echocardiography.2000;8(1):71-77.

BACKGROUND AND OBJECTIVES: Flow-mediated brachial artery vasoactivity has been proposed as a noninvasive means for assessing endothelial function. The present study is designed to assess the influence of aging on endothelial function and when vasoactivity developed initially, peaked. MATERIALS AND METHOD: We measured brachial artery diameter for 60 seconds continuously using 7.5 MHz ultrasound following 5 minutes of lower arm occlusion in 22 normal volun-teers (young group: 10 volunteers, 26.5+/-1.9 years; old group: 12 volunteers, 55.9+/-3.3 years). After sublingual administration of 0.6 mg nitroglycerine, 240 seconds continuously. And then we measure vasoactivity every 3 seconds. RESULTS: Flow-mediated vasodilation (FMD) was started earlier in young group (24.3+/-2.8 sec; old group 28.8+/-3.6 sec, p=0.017). After release of occlusion, peak vasoacitivity time was at 35.5+/-4.7 seconds and peak vasoactivity was 8.4+/-1.7% in young group (old group 6.9+/-1.5%, p=0.099). Endothelial independent vasodilation (EID) was started at 80.7+/-13.3 seconds after sublingual nitroglycerine in young group (vs 80.0+/-19.0 sec), peaked at 177.5+/-16.9 seconds (vs 171.3+/-13.8 sec). Peak vasoactivity was higher in young group (19.1+/-3.1%; old group 15.9+/-2.5%, p=0.033). CONCLUSION: We conclude that 1) Aging has influence on endothelial function about initiating time of vasoactivity as well as peak vaso- activity. 2) FMD can be measured around 50 seconds after release of brachial artery occlusion and EID at 180 seconds after application of sublingual nitroglycerine. 3) The initiating time of vasoactivity (under 30 seconds) can be used for evaluation of endothelial function.

Journal of the Korean Society of Echocardiography.2000;8(1):59-70.

BACKGROUND AND OBJECTIVES: Flow-mediated brachial artery vasoactivity has been recently proposed as a noninvasive means for assessing endotheial function. This endothelial function is impaired in certain cardiovascular conditions, including essential hypertension. METHODS: The study population included 50 healthy subjects aged 22 to 62 years (mean+/-SD, 42+/-12 years), all normotensive, nondiabetic with cholesterol level <220 mg/dL and no family history of premature vascular disease. Normal subjects were classified according to age into those younger than and those older than 40 years. Using high-resolution ultrasound, brachial artery diameter and flow were measured at rest, during reactive hyperemia (with flow increase causing flow-mediated dilation [FMD], which depends on normal endothelial function), and after sublingual nitroglycerin, an endothelium-independent vasodilation. To better characterize this technique, this study was an attempt to assess the flow-mediated vasodilation in two separate protocols (as follows); (1) the stimulus response to various duration of occlusion (using 1 and 5 min), and (2) the stimulus response to various pressure of occlusion (using low and high pressure). In 28 patients (mean+/-SD, 52+/-7 years) with essential hypertension, this study was additionally evaluated endothelial function. The measurements have been compared with those of 14 healthy control subjects. In all subjects, the intima-media thickness (IMT) of the common carotid artery was also measured. This study sought to 1) determine whether endothelial dysfunction was presented in patients with essential hypertension, and 2) examine IMT in these patients. RESULTS: 1) Both in the younger and the older groups, the basal diameter and flow of the brachial artery were significantly increased in men than women. The values were 4.4+/-0.1 mm and 186+/-16 ml/min in men and 3.6+/-0.09 mm and 125+/-13 ml/min in women (p<0.001; p<0.01). In subjects younger than 40 years, flow-mediated dilation (FMD) and the difference in flow response were similar between men and women. But, in subjects older than 40 years, FMD was decreased in men than women (6.6+/-1.6 vs. 14.7+/-1.6%. p<0.01) and the difference in flow response was also decreased in men than women (217+/-24.3 vs. 314+/-40.5%, p<0.05). In younger and older groups, there were no significant change in the nitroglyserin response in either gender. 2) Fifteen normal subjects underwent sequential evaluation following 1 and 5 min of upper arm blood pressure cuff occlusion. There were substantial increase in brachial artery diameter and flow immediately after release of 1 and 5 min of occlusion. The FMD and the difference in flow response following release of occlusion between 5 min duration (11.5+/-1.9%, 253+/-36%) and 1 min duration (6.6+/-1.2%, 53+/-11%) were statistically significant (p<0.05; p<0.001). But, the percent change of diameter following release of occlusion between 5 and 1 min was not statistically significant (p<0.05). 3) Fourteen normal subjects was evaluated the effects of various pressure on endothelial cell function. Inflation pressure was maintained at 30 mm Hg higher than systolic pressure for 5 min and 200 mm Hg (70-90 mm Hg higher than systolic pressure) for 5 min in a random fashion, and then the cuff was suddenly deflated. The diameter and flow response following release of occlusion between high and low pressure were not statistical significance (p>0.05). 4) Flow-mediated dilatation was significantly lower in patients with essential hypertension than in normotensive control subjects (4.2+/-0.8 vs. 7.3+/-1.3 %, p<0.05). Intima-media thickness was significantly higher in patients with hypertension than in normotensive control subjects (0.82+/-0.04 vs. 0.64+/-0.04 mm, p<0.05). Nitroglycerin-mediated vasodilation (9.5+/-1.4 %) in patients with essential hypertension did not differ significantly from those in normotensive control subjects (10.0+/-2.6%, p>0.05). CONCLUSIONS: The study demonstrated that 1) in men older than 40 years, flow-mediated, endothelium-dependent vasodilation of the brachial artery was declined, 2) longer brachial artery occlusion resulted in more vasodilation despite similar hyperemic responses, 3) using low (30 mm Hg higher than systolic pressure) and high (70-90 mm Hg higher than systolic pressure) pressure, each pressure of occlusion was similar hyperemic response, and 4) in patients with essential hypertension, flow-medeiated vasodilation was significantly impaired and IMT was increased than in normotensive control subjects.

Journal of the Korean Society of Echocardiography.2000;8(1):54-58.

BACKGROUND: It has been well recognized that exercise tolerance and angina threshold in patients with coronary artery disease (CAD) are reduced after a meal. But precise mechanism leading to the postprandial worsening of angina has yet to be adequately defined. This study was undertaken to determine the effect of a mixed meal on cardiac performance and heart rate variability (HRV) in patients with CAD. METHODS: 24 patients with angina or myocardial infarction were studied. Echocardiographic examination and heart rate variability test were performed in the fasting state and the other 40-60 minutes after a 600-800 kcal mixed meal. RESULTS: In the postprandial state, resting heart rate was significantly increased by 5.2% from 64.8+/-10.69 beats/min to 68.2+/-10.2 beats/min (p<0.01), stroke volume by 8.1% from 59.6+/-17.3 ml to 64.4+/-18.1 ml (p<0.01), cardiac output by 14.2% from 3.8+/-1.06 to 4.3+/-1.21 (p<0.01). E wave and A wave of mitral filling flow and E/A ratio were not significantly different in the fasting and postprandial tests. But DT and IVRT were significantly increased in the postprandial state (p<0.05, p<0.01 respectively). HRV was not different in the fasting and postprandial state. CONCLUSIONS: In patients with CAD, a 600-800 kcal mixed meal significantly increased resting heart rate, stroke volume, cardiac output, DT and IVRT.

Journal of the Korean Society of Echocardiography.2000;8(1):45-53.

BACKGROUND: Noninvasive measurements that relate to the extent and severity of coronary atherosclerosis have long been sought for clinical screening of patients with chest pain syndromes and for use in clinical trials. Intima-media thickeness (IMT) of the carotid artery has been suggested to be associated with coronary artery atherosclerosis. In this study, we tried to assess the relation of carotid artery atherosclerosis by B-mode ultrasonography with presence and severity of coronary artery disease. METHOD: We studied 57 patients (36 men, 21 women) with ischemic heart disease, mean age 65+/-8 yrs (48 to 83 yrs), who underwent both coronary angiography and carotid ultrasonography with 10 MHz transducer. The patients who had received revascularization procedure were excluded. We classified the patients into two groups, the control group without significant coronary stenosis (18 patients) and the coronary artery disease (CAD) group (39 patients) with significant luminal stenosis (> or =50%). The CAD group was divided into single vessel disease group (SVD, 19 patients) and multivessel disease group (MVD, 20 patients). IMT was measured in far wall of common carotid artery (CCA) at 10 mm proximal to carotid bulb and abnormal IMT was defined if the measurement was greater than mean IMT+2SD of control group. Serum total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), Lipoproteinp (a)(Lp(a)) were measured and history of hypertension, diabetes mellitus, and smoking were investigated. RESULTS: A significant difference in IMT of the CCA was found between control and CAD group (0.76+/-0.09 mm vs. 0.97+/-0.20 mm; p<0.0001). Also a significant difference in the number of atherosclerotic plaque was found between the two groups (control; 0.67+/-1.14 vs. CAD; 1.87+/-1.75; p<0.005). In the CAD group, both mean IMT and numbers of athero-sclerotic plaque tended to increase in MVD group compared with SVD group (1.03 mm vs. 0.91 mm; p=NS, 2.65 vs. 1.05; p<0.05). The sensitivity of IMT for prediction of significant CAD was 66.7%, the specificity 83.3%, the positive predictive value 89.7%, and the negative predictive value 53.6%. The sensitivity of plaque presence on the carotid artery for prediction of CAD was 71.8%, the specificity 61.3%, the positive predictive value 80.3% and the negative predictive value 50.5%. Among risk factor, diabetes mellitus and Lp (a) were correlated well with IMT of CCA, Hypertension was correlated with atherosclerotic plaque. History of smoking was correlated with coronary artery disease. CONCLUSION: Increases in IMT and plaque of the carotid artery, as measured noninvasively by ultrasonography, can be used as a predictor of significant coronary artery stenosis.

BACKGROUND: Pulmonary embolism is associated with varying degrees of pulmonary vascular obstruction. This study was undertaken to establish whether the extent of perfusion defect in lung scintigraphy can be predicted from analysis of echocardiographic measurements in patients with pulmonary embolism. METHODS: We retrospectively studied 28 patients who presented with clinical evidence of pulmonary embolism. In order to compare the extent of perfusion defect in lung scintigraphy, we devised a scoring system (echocardiographic severity index, ESI) for various echocardiographic parameters, which include right ventricle size, area, shape, systolic function, and pulmonary artery pressure. [ESI=sum of scores/number of parameters measured]. RESULTS: The mean values (+/-SD) of each parameter were as follow; right ventricular end-diastolic dimension (RVedD), 34.5+/-5.7 mm; LVedD, 40.9+/-5.2 mm; ratio of RVedD to LVedD, 0.87+/-0.2; right ventricular end-diastolic area (RVedA), 24.7+/-9.5 cm2; right ventricular end-systolic area (RVesA), 17.8+/-7.8 cm2; fractional area change, 28.8+/-9.7%; angle between IVS and RV, 96.0+/-14.8degrees; RV hypokinesia, absence or mild in 29%, moderate in 50%, severe in 21%; TR grade, absence or mild in 25%, moderate in 43%, severe in 32%; pulmonary artery systolic pressure, <30 mmHg in 21%, 30 to 50 mmHg in 68%, >50 mmHg 11% of patients. The echocardiographic severity index (ESI) in patients with pulmonary embolism was 0.52+/-0.24, and the perfusion defect score was 0.21+/-0.14. There was a close correlation between the ESI and the extent of perfusion defect (r=0.622, p<0.01). CONCLUSION: The echocardiographic severity index may reflect the extent of the perfusion defects in patients with pulmonary embolism, therefore it is potentially applicable in clinical practice for evaluating patients with pulmonary embolism and furthermore in their follow-up over a period of time.

Journal of the Korean Society of Echocardiography.2000;8(1):31-35.

BACKGROUND AND OBJECTIVES: Cardiovascular disease is a leading cause of death in patients on long-term dialysis and cardiac mortality decreases after renal transplantation. The aim of this study was to investigate the effects of successful renal transplantation on cardiac structure and function assessed by echocardiography. MATERIAL AND METHOD: Eighteen adult chronic renal failure patients who were taken renal transplantation in our hospital were included. They were submitted to two echocardiographic evaluations at preoperative time and postoperative time (mean: 23months). RESULTS: At the time of transplantation, 18 patients had undergone hemodialysis through a fistula (mean: 44months). At postoperative follow up, blood urea nitrogen/creatinine were decreased and mean hemoglobin level was increased. And systolic/diastolic blood pressure were decreased. Left ventricular mass index, left ventricular posterior wall thickness and septal wall thickness were decreased and ejection fraction was increased by echocardiography. Diastolic function did not improve. Hemodialysis duration and preoperative blood urea nitrogen/creatinine level affected ejection fraction change. CONCLUSION: We observed significantly decreased left ventricular mass index, increased ejection fraction after renal transplantation. We found that the patients who had been onlonger hemodialysis and higher preoperative blood urea nitrogen/creatinine level showed marked improvement of ejection fraction buy echocardiography.

Journal of the Korean Society of Echocardiography.2000;8(1):24-30.

BACKGROUND AND OBJECTIVES: Movement of mitral valve during diastole and blood flow velocity through the valve can be accurately measured using M-mode and pulsed wave Doppler technique, respectively. However, the relationship between mechanical excursion and flow phenomenon at the same cardiac cycle has not been seriously investigated. METHOD: The subjects of this study included twenty cases with normal mitral flow pattern in Doppler echocardiography (Group I, mean age:44+/-20.8years, mean ejection fraction (EF):52+/-20.9%), twenty three cases with relaxation abnormality (Group II, mean age:59+/-11.4years, mean EF:43+/-18.2%) and seventeen cases with restrictive physiology (Group III, mean age: 47+/-15.9years, mean EF: 24+/-11.0%). We measured excursion of mitral leaflets at early (DE) and late (DA) diastole, area of mitral valvular opening using two dimensional calibration on M mode images, and transmitral inflow velocity (E (early ventricular filling)-, A (atrial contraction)-velocity), TVI (time velocity integral) on Doppler echocardiography. RESULTS: DE-excursions (mm) in group I, II, III were 16.8+/-4.7, 14.2+/-3.5, 15.3+/-4.1, DA-excursions (mm) were 9.8+/-3.2, 10.7+/-3.0, 8.3+/-2.7, E-areas (cm2) were 2.8+/-1.3, 2.6+/-0.8, 2.5+/-1.0, A-areas (cm2) were 1.7+/-0.8, 1.7+/-0.7, 2.0+/-0.6, respectively. In E-, A-velocity, deceleration time, E-TVI and A-TVI, there were significant differences among three groups. However, in DE-, DA-excursion, E-, A-area, there were no significant differences among three groups. Between DE excursion and E velocity, DA excursion and A velocity, and total opening area and total TVI in total subjects, significant correlations were absent. CONCLUSION: The mitral excursions and mitral opening areas on M mode images did not show any significant correlations with the mitral inflow velocities and TVI by pulsed Doppler, which suggests that the excursion of mitral leaflets is independent of transmitral inflow.
