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.

A recently reported cardiac syndrome of transient left ventricular dysfunction, clinically resembles acute myocardial infarction and presents with chest pain, ECG changes and minimal elevation of cardiac enzymes in absence of myocardial ischemia or injury. The clinical presentation includes a wide range of symptoms and left ventricular function is normalized completely within days to weeks. This syndrome is likely a non-ischemic, metabolic-dependent syndrome caused by stress-induced activation of the cardiac adrenoreceptors. We report three cases of stress-induced transient LV dysfuction.

Atrial aneurysms involving the free wall or atrial appendage are very rare intracardiac anomalies, less than 100 case reported worldwide. It is usually detected by chance and also could be associated with atrial arrhythmias or systemic embolism. Transthoracic echocardiography and cardiac MRI is the standard diagnostic modality. Aneurysmectomy is usually recommended especially in symptomatic cases. We review the literature and report a case of atrial appendiceal aneurysm, a 23 year-old young man whose diagnosis was established with transthoracic echocardiography and cardiac CT angiography.

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.

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.
