in apical and basal areas. Probably the total type of WMA exists byanalogy with intermediate one with sever local changes.Conclusion: The problem of EchoCG estimation of WMA probablycontains our interpretation of gotten data, not the method’s imperfec-tions. WMA does not complete depend on coronary artery occlusionsite and is not as absolute as it got used. Myocardium contraction is adynamic system explained by conception of infarction heart.

Diagnostic Value of the Main Electrocardiographic Criteria ofLeft Ventricular Hypertrophy Subject to EchocardiographicMethod for its DiagnosisIvan A Serafinovich, Grodno State Medical University, BelarusVolha E Nilitsina, Grodno State Medical University, Belarus

Background: The method of EchoCG estimation of left ventricularhypertrophy influences on the diagnostic value of electrocardiographiccriteria.The aim is to study sensitivity, specificity and correlation the main(Sokolow-Lyon, Cornell voltage, Cornell product) diagnostic criteria ofLVH subject to Echo-LVH criteria with LV wall thickness and LVMM.Design and Method: The transthoracic EchoCG and 12-lead ECGwere performed at 40 hypertensive patients.Analysis 1. All patients were subdivided on the basis of LV wallthickness on two groups: the 1st (n�16) - without LVH and the 2nd(n�24) with LVH.Analysis 2. LVMM All patients were subdivided according to recom-mendation of Penn-Convention on two groups: the 1st (n�10) - with-out LVH and the 2nd (n�30) with LVH.Mann-Whithney test and Spearman test were used.Results: There were not significant difference between all three in-dexes in examined groups (p�0.05). The Sokolow-Lyon indices had asensitivity of 3,33-4,16% and a specificity of 100%; Cornel voltageindices had a sensitivity of 3,33-4,16% and a specificity of 100%,Cornel product indices had a sensitivity of 3,33-8,33% and a specificityof 100%.Any reliable correlation between ECG indices and LV wall thicknesswere not found. Reliable correlation between Cornell voltage, Cornellproduct indices and LVMM was determined.Conclusions: These criteria have a low diagnostic value for LVH. Thecharacteristics of traditional ECG-LVH criteria are weakly depend onmethod for Echo-LVH estimation.The Cornell voltage and Cornell product indices are more preferably inLVH diagnosis than Sokolow-Lyon index.

Background: Transthoracic Doppler echocardiography(TTDE) exam-ination can detect coronary artery and can evaluate coronary circulation

by analyzing coronary flow pattern. While previous studies reported

use of TTDE in evaluating the distal coronary artery, few studies haveevaluated the proximal coronary artery. Then, we applied the TTDE forevaluation of the proximal portion of left coronary artery in patientswith angina pectoris(AP).Methods: Eighty patients with AP were enrolled in this study, and theyunderwent both coronary angiography(CAG)and TTDE. A modifiedshort-axis view was utilized to identify left main and proximal leftanterior descending artery(LAD). After searching for localized aliasingwith color Doppler echocardiography, coronary flow velocities weremeasured at the alias site or the normal site.Results: Visualization of the left main and the proximal LAD waspossible in 65(81%)of the 80 patients. Mean length 19mm of theproximal LAD could be recorded in 65 patients. Localized aliasing wasdetected in 14 patients. The diastolic peak flow velosity was signifi-cantly higher in the alias site than in the normal site(105�40 vs 35�15cm/sec,p�0.001). Localized aliasing by TTDE had a sensitivity of 92%and a specificity of 94% for the detection of significant coronary arterystenosis (�75%) by CAG.Conclusion: TTDE could detect and evaluate proximal left coronaryaretry stenosis directly. TTDE is a useful non-invasive tool for pre-dicting proximal left coronary artery stenosis in patients with AP.

Echocardiographic Features of Congenital VentricularDivertivula: 7 Case Reports and Review of LiteratureLin Sun, Beijing Anzhen Hospital, Capital Medical University, ChinaZhian Li, Beijing Anzhen Hospital, ChinaYihua He, Echocardiography, ChinaXiaoyan Gu, ChinaYe Zhang, Beijing Anzhen Hospital, Capital Medical University,ChinaJV Ian Nixon, Virginia Commonwealth University, Richmond, UnitedStates

Objective: To discuss the echocardiographic manifestations and clas-sification of congenital ventricular diverticula.Methods: Seven cases of congenital diverticula were retrospectivelysummarized in our database from 2000 to 2008. The morphologicalcharacteristics and other cardiac abnormalities were analyzed. Alsoclinical history, other accessory examinations and surgical findingswere reviewed.Results: 8 diverticula of all 7 cases were found by echocardiography.6 of 8 diverticula were fibrous types with thin wall, high echo intensity,akinesis and narrow apical connections to the ventricles, or wideconnections to the ventricles but near the atrioventricular rings. 2 of allthe 8 diverticula were accompanied with other cardiac abnormalities.All the 6 fibrous diverticula were complicated by ventricular arrhyth-mia. And among them, one apical diverticula was complicated by leftventricular insufficiency. Finally 5 cases underwent surgeries and sur-gical findings confirmed echocardiographic results.Conclusion: Congenital ventricular diverticula are rare. They can beclassified into different types such as apical or nonapical, and fibrous ormuscular. Maybe, the fibrous and muscular diverticula are just thedifferent stages of a diverticulum. Moreover, because of their compli-cations including heart failure, ventricular rupture, ventricular arrhyth-mia and sudden death, the treatments to diverticula are relatively active.Echocardiography may find out the characteristics of different ventric-ular diverticula, their complications, other cardiac or extracardiac ab-normalities and distinguish them from ventricular true or pseudo-aneurysms, hernias, and pericardiac cysts or diverticula. In view of

these, echocardiography can help the clinicians make decision.
