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.

BACKGROUND: Cardiac involvement in Duchenne muscular dystrophy (DMD) is common, but usually latent without symptoms or signs in the initial period of disease. This study investigated the incidence and predictor of cardiac involvement in DMD patients. METHOD: From January 2000 to June 2005, we enrolled 45 patients with DMD (aged 20.2+/-3.0 years) who admitted to the Yongdong Severance Hospital. Electrocardiography and transthoracic echocardiography was done to evaluate the cardiac function. RESULT: Electrocardiographic abnormalities were present in 80.1% of patients. Sinus tachycardia was most common (50%). LVEF was decreased (46.7+/-13.8%), and 56% of the patients had diastolic dysfunction. Patients with pulmonary involvement were older (20.7+/-3.8 vs 17.6+/-2.8 years, p=0.028), and patients with reduced LVEF (<50%) had longer duration of disease (11.4+/-4.4 vs 14.3+/-2.4 years, p=0.04). However, on multivariate analysis, age, duration of disease, pulmonary involvement, dyspnea symptom, electrocardiographic abnormality was not an independent predictor for LV systolic dysfunction in adolescent and adult patients with DMD. CONCLUSION: Cardiac involvement in adolescent and adult patients with DMD was frequently observed independent of age, duration of disease, pulmonary involvement, and dyspnea symptom. Therefore, more active cardiac investigation is required in patients with DMD, even without clinical suspicion.

Stroke, a sudden development of a focal neurologic deficit, remains as a frequent leading cause of death even in Korea. Five to 13% of strokes occur in patients with younger than 45 years of age; up to 40% of strokes occur in patients without occlusive cerebrovascular disease; and it is estimated that the source is cardiac origin in 15 to 20%. Another 30n to 40% are in the category of stroke of undetermined cause, also known as cryptogenic stroke. An increasing number of echocardiographic findings have been found in this group of cryptogenic stroke patients and in patients with embolic stroke. Cardiac tumors can be a source of emboli, but the most commonly implicated sources are thrombi from the left atrial appeadage or left ventricle, left atrial spontaneous contrast, atrial septal aneurysm associated with a patent foramen ovale (PFO), thrombi traversing a PFO, valve vegetations, protruding aortic atheroma of aortic arch, and emboli associated with mitral and aortic prostheses. Echocardiography is most helpful in defining the cause of cerebrovascular ischemia in patients without occlusive cerebrovascular disease. For complete evaluation of potential source of cardiac embolic sources, transesophageal echocardiography (TEE) is required because many of the entities such as left atrial appendage thrombus can be detected only with this technique.

Left ventricular thrombus (LVT) is a frequent complication in patients with acute large anterior myocardial infarction or dilated cardiomyopathy. The clinical importance of LVT lies in its potential for systemic embolization. We experienced a case of surgically treated LVT in a patient with acute myocarditis with embolic splenorenal infarction.

Lipomatous hypertrophy of interartiral septum (LHIS) is a rare entity that is characterized by the excessive deposition of fat in the interatrial septum. The appearance of LHIS on echocardiogram is a bilobed or dumbbell-shaped in interatrial septum. We report a case of 56-years man with frequent premature ventricular contraction on holter monitoring which may related to his sudden cardiac death diagnosed lipomatous hypertrophy of interatrial septum by echocardiography.

2D echocardiography (2DE) is a well established tool for the diagnosis of the mechanical complications after acute myocardial infarction (AMI) such as free wall and ventricular septal rupture. However, the extension of the rupture and the relationship with contiguous anatomic structures may not be clearly defined by 2DE. Real-time 3D echocardiography (RT3DE) is known to provide surgical enface view allowing complete visualization of the cardiac structures and comprehension of their spatial orientations to other anatomic structures. Obtaining such information with RT3DE before operation in AMI patient with mechanical complication may be essential for the optimal surgical treatment. We report a case of extensive ventricular wall rupture from the posterior wall to the ventricular septum after AMI demonstrated by RT3DE.

Midventricular obstructive hypertrophic cardiomyopathy (MOHCM) is a rare variant of hypertrophic cardiomyopathy. Apical dilatation and myocardial infarction can be complicated without significant coronary artery disease. We report a case of apical dilatation in a patient with MOHCM without atherosclerotic coronary artery disease. A 76-year-old woman was admitted for recent cerebral infarction and consulted to cardiologist for abnormal electrocardiographic findings. She had been suffering from exertional dyspnea (NYHA II) for about four years. Two dimentional-echocardiography revealed midventricular obstructive hypertrophy with an apical dilatation and paradoxical jet flow from the apical aneurysm to the left ventricular outflow tract during early diastole. Cardiac catheterization demonstrated dyskinesia in the apical wall with midventricular obstruction and a peak-to-peak intraventricular pressure gradient of 110 mmHg during pull-back from the apical high-pressure chamber to the subaortic low-pressure chamber in the left ventricle. Coronary angiograms showed no significant stenotic lesion of the coronary arteries. She was prescribed oral beta-adrenergic antagonist to decrease the intraventricular pressure gradient.

BACKGROUND: Severe tricuspid regurgitation (TR) may develop later after mitral valve replacement (MVR) in the absence of prosthetic mitral valve (MV) dysfunction and other causes of left heart failure. The aim of this study was to investigate the incidence and predictors of severe TR late after MVR for rheumatic MV disease. METHODS: From 309 patients who underwent MVR between 1995 and 1997 at Yonsei Cardiovascular Hospital, we selected 193 patients (M:F=52:141; mean age 48.5+/-11.3) who underwent MVR for rheumatic valvular disease [concomitant TAP (Tricuspid annuloplasty) group: 56, No TAP group: 137]. The mean follow up duration was 83.2+/-26.4 months. Primary end point was time to clinical events, such as death, reoperation for tricuspid valve, admission due to right heart failure and the development of severe TR without left side heart failure. Patients were classified into 3 groups based on the degree of TR at the time of MVR: Group I; patients with coexisting mild TR (Grade 0, trivial), Group II; mild to moderate TR (Grade I-II), Group III; severe TR (Grade III-IV). RESULTS: Twenty-one patients (10.9%) developed clinical events [Group I: 2/78 (2.6%), Group II: 8/76 (10.5%), Group III: 11/39 (28.2%)]. Event free survival rate was different during the follow-up period between groups. By Cox regression analysis, initial severe TR (Hazard Ratio: 5.2, 95%CI 2.2-12.3), old age (Hazard Ratio: 4.3, 95%CI 1.4-12.8), and TAP (Hazard Ratio: 4.3, 95%CI 1.8-10.5) were the risk factors for the development of late severe TR. CONCLUSION: The incidence of severe TR or right heart failure in the absence of prosthetic MV dysfunction was 10.9% in MVR patients. Despite of successful TAP, the severity of TR at the time of MVR was the most important factor for prediction of late severe TR. It can be suggested that initial TR grade and RV function rather than TAP, is the important factor for the recurrence of severe TR after MV surgery.
