BACKGROUNDLeft atrial enlargement has been suggested as a more robust marker of diastolic dysfunction. We hypothesize that the ratio of left atrial volume to left ventricular volume (LAV/LVV) may be more reasonable to reflect left atrial enlargement in the patients with hypertension, because hypertensive patients have a characteristic of concentric remodeling of the left ventricle which is often accompanied with diastolic dysfunction. The aim of this study was to determine if the LAV/LVV can be used as a new parameter to assess left atrial size in hypertensive patients and the relationship between the LAV/LVV and diastolic dysfunction.
METHODSNinety-one patients with hypertension and forty-three normal controls were studied. The hypertensive patients were assigned to the normal wall (NW) and hypertrophic wall (HW) groups. The left atrial diameter (LAD), LAV, left atrial volume index (LAVi), LVV and LAV/LVV were measured and calculated by 2-dimensional echocardiography and real time 3-dimensional echocardiography. All of the above parameters were used to evaluate the size of the left atrium. The ratio of peak E velocity of mitral valve inflow to peak E' velocity of lateral mitral annulus (E/E') was measured by pulse Doppler and tissue Doppler. This parameter was used to evaluate diastolic function.
RESULTSThe LAD, LAV, LAVi, LAV/LVV and E/E' in hypertensive groups were significantly higher than those in the normal group (P < 0.05 or 0.01), and those in the HW group were significantly higher than those in the NW group (P < 0.05 or 0.01). The E/E' had a positive correlation with LAV, LAVi and LAV/LVV. The correlation coefficient between E/E' and LAV/LVV was relatively higher than that between E/E' and LAD or LAVi.
CONCLUSIONLAV/LVV may be used as a new index to evaluate left atrial size in hypertensive patients with diastolic dysfunction.

Endomyocardial biopsy (EMBx) is a useful tool for diagnosing various cardiac pathologies. However, the routine use of EMBx has not gained widespread acceptance due to the possible complications related to the EMBx. Thus, not much information is available on the complications related to the EMBx. We prospectively evaluated 90 consecutive patients who underwent 2-D echocardiography guided transfemoral right ventricular EMBx at Kyungpook National University Hospital between March 2002 and November 2005 to determine the incidence, nature and subsequent management of complications related to EMBx. The clinical diagnoses before the EMBx were arrhythmogenic right ventricular dysplasia in 54, dilated cardiomyopathy in 19, Brugada syndrome in 9, myocarditis in 6 and miscellaneous in 2 patients. The overall major complication rate was 5.6% and no procedure-related mortality occurred. Myocardial perforation (n=3), which was the most frequent complication, did not progress to cardiac tamponade requiring pericardiocentesis in any patient. Hemodynamically unstable ventricular tachycardia occurred in 1 patient. New and persistent right bundle branch block occurred in another. Our findings suggest that 2-D echocardiography guided transfemoral right ventricular EMBx is a relatively safe procedure.

A 32-yr-old man developed progressive exertional dyspnea 4 yr after blunt chest trauma due to an automobile accident. Two-dimensional echocardiography and computed-tomographic coronary angiography demonstrated a large pseudoaneurysm of the left ventricle and severe tricuspid regurgitation. The patient underwent successful surgical exclusion of the pseudoaneurysm by endoaneurysmal patch closure and repair of the tricuspid valve regurgitation. To the best of our knowledge, this is the first case of these 2 different pathologies presenting late simultaneously after blunt chest trauma and successful surgical repairs in the published literature.

OBJECTIVETo investigate the clinicopathologic manifestations of non-compaction of ventricular myocardium (NVM).
METHODSClinical data, electrocardiograms, echocardiography images and pathologic changes were studied in five cases of non-compaction of ventricular myocardium.
RESULTSThe patient's ages ranged from 29 to 57 years old, all were males. Abnormal electrocardiograms were obtained in all of the 5 cases. Among them, 3 were diagnosed using echocardiography. Histopathologic examination showed that there were abnormally coarse muscle trabeculation and deep recesses, interlacing in arrangement, over the inner wall of the heart chambers. The compacted myocardium became thinning down gradually from the base to the apex of the heart. The non-compacted myocardium bundles locating close to the endocardium were coarse and orderless in arrangement, nuclei were irregular and abnormal, nevertheless, the arrangement and appearance of the muscle bundles near by the pericardium part were essentially normal and the cell nuclei were evenly distributed.
CONCLUSIONThere are no specific clinical manifestations obtained in patients with non-compaction of ventricular myocardium, however, the pathologic changes are characteristic and a clinical diagnosis can be made by using echocardiography.

BACKGROUNDUmbilical cord around neck, a common obstetric complication, affects fetal hemodynamics. Does it influence fetal cardiac functions? The purpose of this study was to investigate the left and right ventricular systolic and diastolic functions of fetuses with umbilical cord around neck in the third trimester by applying velocity vector imaging (VVI).
METHODSThirty-five cases of fetuses with umbilical cord around neck whose gestational ages from 35 to 40 weeks were selected, including 20 cases of umbilical artery ratio of the highest systolic velocity (S) to the lowest diastolic velocity (D) (S/D) < 3.0 and 15 cases of umbilical artery S/D ≥ 3.0, while 20 cases of normal fetuses of 35 - 40 gestational weeks were selected as the control group. The changes in longitudinal velocity, strain, and strain rate of fetal left and right ventricle in systole and diastole in two groups, and the changes in fetal cardiac function under the situation of umbilical cord around neck were analyzed.
RESULTSLongitudinal strain and strain rate overall of fetal left and right ventricle in systole and diastole were less in fetuses with umbilical artery S/D (3)3.0 and umbilical cord around neck than those in fetuses with umbilical artery S/D < 3.0 and those in control group (P < 0.05); there was no significant difference (P > 0.05) in longitudinal strain and strain rate overall of fetal left and right ventricle in systole and diastole between fetuses with umbilical artery S/D < 3.0 and those in control group.
CONCLUSIONSLeft and right ventricular systolic and diastolic dysfunction was detected in fetuses with umbilical cord around neck and umbilical artery S/D (3)3.0. VVI could sensitively respond to cardiac function changes in fetuses with umbilical cord around neck, which provides another valuable method in the evaluation of fetal cardiac function.

Endomyocardial biopsy (EMB) is one of the reliable methods for the diagnosis of various cardiac diseases. However, EMB can cause various complications. The purpose of this study is to evaluate the complication of transfemoral EMB with both fluoroscopic and two-dimensional (2-D) echocardiographic guidance. A total of 228 patients (148 men; 46.0+/-14.6 yr-old) who underwent EMB at Kyungpook National University Hospital from January 2002 to June 2012 were included. EMB was performed via the right femoral approach with the guidance of both echocardiography and fluoroscopy. Overall, EMB-related complications occurred in 21 patients (9.2%) including one case (0.4%) with cardiac tamponade requiring emergent pericardiocentesis, four cases (1.8%) with small pericardial effusion without pericardiocentesis, two cases (0.9%) with hemodynamically unstable ventricular tachycardia (VT), one case (0.4%) with nonsustained VT, one case (0.4%) with tricuspid regurgitation, twelve cases (5.3%) with right bundle branch block. There was no occurrence of either EMB-related death or cardiac surgery. Left ventricular ejection fraction was significantly lower (32.0+/-18.7% vs 42.0+/-19.1%, P=0.023) and left ventricular end-diastolic dimension was larger (60.0+/-10.0 mm vs 54.2+/-10.2 mm, P=0.013) in patients with EMB related complications than in those without. It is concluded that transfemoral EMB with fluoroscopic and 2-D echocardiographic guidance is a safe procedure with low complication rate.
