We report a case of a distal seeding of invasive thymoma at descending abdominal aortic wall. It is relatively common that direct extension of invasive thymoma into the adjacent great arteries and veins. But distal seeding of invasive thymoma is extremely rare. We found abnormal mass at abdominal aortic wall incidentally during routine transthoracic echocardiography. Operation of aortic segment replacement and mass removal was carried out. Histological evaluation of mass found invasive thymoma.

Congenital right ventricular diverticulum is extremely rare and is associated with other congenital cardiac anomalies. It functionally behaves like an accessory ventricular chamber which contracts synchronously with the normal ventricles. Only dozens of patients with right ventricular diverticulum have been reported in literature worldwide and one case in Korea. An apical right ventricular diverticulum occurs in patients with thoracoabdominal midline defects or abnormalities of the cardiac position. However, an antero-superior diverticulum is usually associated with other congenital cardiac defects, such as a ventricular septal defect, tetralogy of Fallot, double outlet right ventricle, and pulmonary stenosis. We report a 69-year-old woman with a congenital right ventricular diverticulum without associated cardiac anomalies. The right ventricular diverticulum was diagnosed by echocardiography, right ventriculography, and cardiac MRI.

Rupture of the interventricular septum is a serious complication of acute myocardial infarction, accounting for 5% of death due to acute myocardial infarction. The mortality with medical therapy alone exceeds 90%. Accurate diagnosis, urgent management, and early operative correction are necessary for survival. We report cases of 3 patients with ventricular septal rupture after acute myocardial infarction.

Double-chambered right ventricle (DCRV) is a congenital cardiac anomaly in which the right ventricle is divided into two chambers by anomalous hypertrophied muscle bundles that cross the right ventricular cavity. DCRV may be associated with other congenital cardiac anomalies, most commonly with ventricular septal defect. We report two cases of DCRV without other congenital cardiac anomalies with review of literatures. We performed echocardiography, cardiac catheterization and right ventricular angiogram to confirm the diagnosis.

Myocardial calcification is usually classified as either dystrophic or metastatic. Dystrophic calcification is more common and usually occurs in the area of prior myocardial infarction. It is found in 8% of patients who have been survived longer than 6 years after myocardial infarction. The most common site of calcification is in the anterior wall of the left ventricle or apical and anterolateral aspect in the aneurysm of the left ventricle. We report the case of a 50-years old man with a typical dystrophic calcification of the endocardium in area of myocardial necrosis.

Intravenous leiomyomatosis is an uncommon benign tumor arising from either the uterine venous wall or uterine leiomyoma. Although this tumor is usually confined to the pelvic cavity, sometimes it can extend into the cardiac cavity and brings on sudden death. We report a case of intravenous leiomyomatosis extending into the right atrium, right ventricle and both pulmonary arteries by seeding. The tumor was detected with transthoracic echocardiography and appropriately diagnosed by transesophageal echocardiography and cardiac MRI. Entire tumor was successfully removed by one-stage radical surgery under cardiopulmonary bypass.

Fibrosing mediastinitis is a rare benign disorder caused by excessive proliferation of fibrous tissue within the mediastinum. Pulmonary artery stenosis is uncommon complication of fibrosing mediastinitis. We present a case of percutaneous stent deployment in a patient with severe pulmonary artery stenosis causing pulmonary hypertension secondary to fibrosing mediastinitis.

BACKGROUND: Recognition of ischemic right ventricular (RV) dysfunction in the course of inferior wall left ventricular (LV) acute myocardial infarction is important in clinical practice. The Doppler Tei index is useful for estimating global cardiac function. However, the clinical usefulness of RV Tei index to diagnose subclinical RV dysfunction has not been investigated. The purpose of this study was to assess the clinical value of RV Tei index for diagnosis of subclinical RV dysfunction associated with inferior wall acute myocardial infarction who did not have definite ECG changes at right precordial leads. METHODS: The study population consisted of 22 consecutive patients (male 10, average age 57+/-12) with acute inferior myocardial infarction who did not have specific ST segment changes at right precordial leads. RV Tei index was measured by Doppler echocardiography and RV ejection fraction (EF) was measured by multigated blood pool (MUGA) SPECT. We defined subclinical RV dysfuntion as estimated RA pressure was > or =10 mmHg (group 1) by right heart catheterization. RESULTS: In patients with RV dysfunction, RV Tei index was significantly increased compared with those who did not have RV dysfunction (0.51+/-0.22 vs 0.35+/-0.18, p<0.05). RVEF by MUGA blood pool SPECT was significantly decreased in patients with RV dysfunction (35+/-11% vs 47+/-12, p<0.05). CONCLUSION: RV Tei index is simple and useful non-invasive method for diagnosis of subclinical RV dysfunction associated with inferior wall acute myocardial infarction who did not have typical ECG changes at right precordial leads.

BACKGROUND: Aging is an important factor to determine transmitral inflow velocity pattern. Cardiac geometry such as left ventricular (LV) volume, mass and left ventricular outflow tract (LVOT) was also changed with age. The aim of this study was to assess the impact of geometric change of LVOT on transmitral inflow velocity pattern excluding a factor of age. METHODS: Healthy 115 (61 men, 37+/-15 years) individuals were enrolled. Echocardiography was performed to measure LV mass, thickness, left atrial (LA) size, aortoseptal angle (ASA), early (E) and late (A) transmitral inflow velocity, and deceleration time (DT). ASA was measured at mid-diastole in apical long-axis view according to a method as the open angle between the edge of the interventricular septum and axis perpendicular to the aortic annulus. The relation between transmitral inflow velocity pattern and LV geometric parameters was analyzed by regression analysis. RESULTS: Simple regression analysis demonstrated a significant correlation between transmitral inflow parameters with age and geometric parameters (ASA, LA size and LV mass index). Multiple regression analysis, taking into consideration age, ASA, LA size and LV mass index showed that only age was an independent predictor for E, A, DT, and E/A ratio (r2=0.210, Beta coefficient (beta)=0.459, p<0.001;r2=0.427, beta=0.654, p<0.001;r2=0.227, beta=-0.476, p<0.001;r2=0.436, beta=-0.661, p<0.001, respectively). But, excluding age, ASA was an independent predictor for E, A, DT, and E/A ratio (r2=0.151, beta=0.389, p<0.001;r2=0.294, beta=0.542, p<0.001;r2=0.227, beta=-0.476, p<0.001;r2=0.260, beta=0.509, p<0.001, respectively). CONCLUSION: ASA, a parameter of LVOT geometry, might be an important factor related to transmitral inflow velocity pattern excluding a factor of age.
