The Case of Isolated Double Atrial Septum with Persistent Interatrial Space.
Journal of Cardiovascular Ultrasound.2013;21(4):197-199. doi:10.4250/jcu.2013.21.4.197
Double atrial septum is very rare atrial septal malformation which has double layered atrial septum with persistent interatrial space between the two atria. Clinically, most cases of this anomaly are asymptomatic unless manifest as thromboembolic complications, such as stroke, or transient ischemic attack, that thrombus may be originated from this interatrial space. We report a case of a 69-year-old man who was diagnosed with isolated double atrial septum by transthoracic echocardiography.

Large Pleural Effusion Causing Right Atrial Collapse and Tachycardia.
Journal of Cardiovascular Ultrasound.2006;14(2):67-69.
We observed one patient with large pleural effusion causing severe dyspnea, tachycardia, and severe right atrial collapse, which findings were completely resolved after thoracentesis. Our report shows that massive pleural effusion also can make severe right atrial collapse and symptom like cardiac tamponade, and thoracentesis can improve this condition.

A Case of Aortic Root Abscess Causing Fatal Myocardial Infarction.
Journal of Cardiovascular Ultrasound.2006;14(2):63-66.
Despite the major advances in diagnostic technology and improvements in antimicrobial selection and monitoring accompanied by parallel advances in surgical techniques, the morbidity and mortality of infective endocarditis(IE) still remain high. Because of this high mortality rate, it is worthy of investigating the clinical features of IE and it's complications thoroughly. The main causes of mortality in IE are congestive heart failure and septic embolization. In 9% of active IE, acute myocardial infarction(AMI) developed. AMI caused by coronary artery obliteration by occlusion or embolization is a rare but recognized complication of aortic valve endocarditis with annular abscess. We reported a case of aortic valve endocarditis with aortic root abscess which was complicated by AMI and death.

A Case of Prosthetic Valve Dysfunction in the Aortic Position: Caused by Pannus Formation.
Journal of Cardiovascular Ultrasound.2006;14(2):60-62.
Prosthetic valve dysfunction caused by pannus formation is an infrequent but serious complication of heart valve replacement. Although the precise mechanisms of the pannus formation are not clearly understood, it is considered to be the result of a bioreaction to the mechanical prosthesis. Prosthetic valve design, surgical techniques, infection, and inadequate anticoagulation also contribute to the pannus formation. In this report, we present one patients who had undergone aortic valve replacement(AVR) with the 20-mm Medtronic Hall prosthetic valve and underwent repeated AVR due to pannus ingrowth in the late postoperative period.

BACKGROUND: Left ventricular(LV) adaptation to high blood pressure produces unique geometrical change, which is closely associated with the prognosis and quality of life in hypertensive patients irrespective of the presence of LV hypertrophy. Exercise capacity assessed by treadmill test(TMT) can provide prognostic information in these patients. We evaluated relationship between LV geometry and exercise capacity in hypertensive patients with isolated diastolic dysfunction. METHODS: According to the echocardiographic results, 109 patients with essential hypertension, who performed TMT for estimating exercise capacity, were classified as having normal LV geometry (NG, n=40) or concentric LV geometry (CG, n=69). Patients with concentric LV geometry were categorized into moderate (n=55) or marked (n=14) CG on the basis of the criteria previously reported. Conventional echocardiographic and tissue Doppler imaging indices were obtained with standard techniques. RESULTS: There were no differences in age, gender and resting heart rate between NG and CG. Maximal exercise time was longer in NG than in CG (617.3+/-131.5 vs. 566.0+/-155.0 seconds, p<0.05). Late diastolic mitral annular velocity (AO) exhibited a significant correlation with maximal exercise time in moderate and marked CG (r=0.30 and 0.56, both p<0.05), which remained significant after multivariate linear regression analysis with variables such as age, LV mass, early to late mitral inflow ratio, AO velocity, LV ejection fraction and left atrial size, whereas such a correlation could not be found in NG. CONCLUSION: Since exercise performance decreases when there is LV concentric remodeling, LV geometry needs to be considered in the assessment of exercise capacity in patients with essential hypertension and isolated diastolic dysfunction. Atrial systolic function plays a crucial role in maintaining exercise capacity in these patients, especially in those with increased LV concentricity.

BACKGROUND: Carotid intima media thickness (CIMT) and the presence of carotid plaque have been used for risk stratification of cardiovascular disease (CVD). To date, however, the association between multi-directional functional properties of carotid artery and CVD has not been fully elucidated. We sought to explore the multi-directional mechanics of the carotid artery in relation to cardiovascular risk. METHODS: Four hundred one patients who underwent carotid ultrasound were enrolled between January 2010 and April 2013. A high risk of CVD was defined as more than 20% of 10-year risk based on the Framingham risk score. Using a speckle-tracking technique, the longitudinal and radial movements were analyzed in the B-mode images. Peak longitudinal and radial displacements, strain and strain rate were also measured. Beta stiffness and elastic modulus index were calculated from the radial measurements. RESULTS: Of the overall sample, 13% (52) of patients comprised the high-risk group. In multivariate logistic regression, CIMT and elastic modulus index were independently associated with a high-risk of CVD {odds ratio (OR): 1.810 [95% confidence interval (CI) 1.249–2.622] and OR: 1.767 (95% CI: 1.177–2.652); p = 0.002, 0.006, respectively}. The combination of CIMT and elastic modulus index correlated with a high-risk of CVD more so than CIMT alone. CONCLUSION: The elastic modulus index of the carotid artery might serve as a novel surrogate marker of high-risk CVD. Measurement of the multi-directional mechanics of the carotid artery using the speckle tracking technique has potential for providing further information over conventional B-mode ultrasound for stratification of CVD risk.

BACKGROUND: Incidence of diastolic dyssynchrony (DD) and its impact on functional recovery of left ventricle (LV) after ST segment elevation myocardial infarction (STEMI) is not known. METHODS: Consecutive patients with STEMI who underwent successful revascularization were prospectively enrolled. Echocardiography with tissue Doppler imaging was performed within 48 hours of admission and at 6 months. LV end-diastolic volume index (EDVI), end-systolic volume index (ESVI), ejection fraction (EF), and left atrial volume index (LAVI) were calculated. Diastolic delay was calculated from onset of QRS complex to peak of E wave in tissue Doppler image and presented as maximal temporal difference between peak early diastolic velocity of 6 basal segments of LV (TeDiff). Study patients were compared with demographically matched control group. RESULTS: Forty eight consecutive patients (55 ± 10 years, 88% male) and 24 controls (56 ± 6 years, 88% male) were included. TeDiff was higher in STEMI than in controls (35.9 ± 19.9 ms vs. 26.3 ± 6.8 ms, p = 0.025). Presence of DD was higher in STEMI than controls (58% vs. 33%, p = 0.046) according to calculated cut-off value (≥ 29 ms). There was no correlation between TeDiff and change in EDVI, ESVI, and LAVI at 6 months, however TeDiff and change in EF at 6 months was positively correlated (r = 0.328, p = 0.023). Patients with baseline DD experienced remodeling less frequently compared to patients without baseline DD (11% vs. 38%, p = 0.040) during follow-up. CONCLUSION: STEMI disrupts diastolic synchronicity of LV. However, DD during acute phase of STEMI is associated with better recovery of LV thereafter. This suggests that DD is associated with peri-infarct stunned myocardium that is salvaged with primary intervention as well as infarct size.
