Abstract PDF: The common causes of organic mitral regurgitation (MR) include mitral valve prolapse (MVP) syndrome, rheumatic heart disease, and endocarditis. MR also occurs secondary to dilated cardiomyopathy and coronary artery disease. In acute severe MR, the hemodynamic overload often cannot be tolerated, and mitral valve repair or replacement must be performed immediately. We report herein a case of severe MR due to coronary vasospasm that was confirmed via ergonovine echocardiography in a 70-year-old man. He was scheduled to undergo mitral valve surgery, but it did not push through and he was put on medical therapy.

Abstract PDF: The incidence and importance of tricuspid valve regurgitation after a blunt chest injury has risen with the increase in the number of automobile accidents and steering wheel traumas. This kind of injury has been reported more frequently in the last decade because of the better diagnostic procedures and understanding of the pathology. However, tricuspid valve regurgitation following a blunt chest injury can still be easily missed because most patients do not show symptoms at the time of the trauma. A 55-year-old male patient presented himself at our facility after suffering a chest injury from an automobile accident. His transthoracic echocardiography (TTE) revealed severe tricuspid valve regurgitation due to the prolapse of his anterior valve leaflet. We report a case of asymptomatic tricuspid regurgitation that developed after a blunt chest injury.

Abstract PDF: Loeffler's endocarditis involves progressive eosinophilic infiltration of the endocardium, which leads to apical thrombotic obliteration of the ventricle and endomyocardial fibrosis, that may finally represent a characteristic feature of restrictive cardiomyopathy. This paper presents a case of a 44-year-old male with symptoms of dyspnea and peripheral hypereosinophilia, who was diagnosed with early stage Loeffler's endocarditis via multicardiac imaging modalities.

Abstract PDF: Apical hypertrophic cardiomyopathy is rare disease and a variant of hypertrophic cardiomyopathy with prevalence of 1 in 500 in the general population. Apical hypertrophic cardiomyopathy with apical aneurysm and intramural thrombus is extremely rare. We report a case of apical hypertrophic cardiomyopathy progressing to left ventricular apical aneurysm with intramural thrombus diagnosed by contrast echocardiography.

Abstract PDF

BACKGROUND
Echocardiography is rapidly established itself as the primary diagnostic technique for investigation of children with heart disease, and referrals are increasing to the pediatric cardiology clinic for investigation. However, because there is a lack of analysis data on the patients referred to pediatric cardiology clinics, we have proceeded to compare and analyze their characteristics to provide basic data base. METHODS: From Oct. 1, 1998 to Jul. 10, 1999, total 443 cases referred to the pediatric cardiology clinic of Yeungnam University Hospital were studied retrospectively by medical records, chest X-ray, EKG and echocardiography, etc. RESULTS: The results were as follows. 1. The proportion of male was 61.0%(261 cases) and that of female was 39.0%(167 cases). The ratio of male to female was 1.6:1. The proportion infants less than 1 year-old was 62.6%(268 cases) of all patients. 2. Cardiac murmur was present in 248 cases(57.9%), which was the most common case of referral to the pediatric cardiology clinic. The impression at referral was more congenital heart disease(70.6%) than acquired heart disease(17.8%) and arrhythmia(11.6%). 3. The final diagnosis was as follows : congenital heart disease was present in 212 cases(49.5%), acquired heart disease, 59 cases(13.9%); arrhythmia, 13 cases(3.0%); normal heart, 144 cases(33.6%). CONCLUSION: Among the patients referred to pediatric cardiology clinic, 33.6%(144 cases) had normal hearts and why these patient were referred may be possibly due to more dependence on echocardiography than on auscultation instruction. Threfore, clinical and auscultatory skill should be emphasized to minimize dependence on expensive echocardiography for evaluation of pediatric heart disease.

Abstract PDF: BACKGROUND
Left ventricular diastolic filling is an important determinant for maintenance of cardiac output during hemodialysis. Few investigators have studied the influence of hemodialysis on diastolic function. To evaluate the change of left ventricular systolic and diastolic function, we performed M-mode and Doppler echocardiopraphic studies before and after hemodialysis. METHODS: The study population consisted of 30 patients(15 patients were male, mean age 45+/-10 years) with CRF on maintenance henodialysis. They have normal left ventricular systolic function(Fractional shortening > 30%) and no evidence of valvular heart disease or regional wall motion abnormalities. The ejection fraction(EF) was measured using M-mode echocardiography and Doppler indices such as peak E velocity, peak A velocity, isovolumetric relaxaion time(IVRT), deceleration time(DT), and left ventricular ejection time(LVET) obtained from Doppler echocardiography. The index of myocardial performance(IMP) was calculated from each of the Doppler velocity indices. RESULTS: The weight reduction after hemodialysis was 2.1+/-1.0kg(p<0.0001). After hemodialysiss, there was some decrease in blood pressure(p<0.05), but no significant change in heart rate, EF and fractional shortening, mean VCF, peak A velocity, and DT. And significant in IVRT and IMP(p<0.05, p<0.0001) were noted. CONCLUSTION: In conclusion, preload reduction is the main mechanism that accounts for changes in Doppler diastolic indices after hemodialysis. And and increased IMP suggests that diastolic function may be aggravated after gemodialysis, and that implies impaired left ventricular filling and disturbed left ventricular compliance.
