[Tricuspid and mitral regurgitation due to congenital hypoplasia of atrioventricular valves in the aged: a case report].

A 76-year-old woman with a history of repeated right-sided cardiac failure during the past 2 years presented with tricuspid and mitral regurgitation due to congenital hypoplasia of atrioventricular valves. Two-dimensional echocardiography demonstrated enlarged right atrium and right ventricle, and discoaptation between the leaflets. Color Doppler echocardiography revealed severe tricuspid regurgitation through the gap between the leaflets.

A case of cardiac sarcoidosis with remarkable atrophy of the left ventricular septum on two-dimensional echocardiography.

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology which mainly affects the lungs, skin, the lymphoreticular system, and the heart. We report a case of cardiac sarcoidosis in which a remarkably thin ventricular septum was demonstrated on two-dimensional echocardiography.

[Effects of oral flecainide treatment of refractory tachyarrhythmias].

Oral flecainide treatment was given to five patients who were refractory to conventional antiarrhythmic agents. The five patients included one with atrioventricular reentrant tachycardia (AVRT), one with non-sustained ventricular tachycardia (nsVT) and three with sustained VT (sVT). Flecainide produced favorable responses in patients of AVRT, nsVT and sVT with arrhythmogenic right ventricular dysplasia (ARVD).

[Lassa fever associated with effusive constrictive pericarditis and bilateral atrioventricular annular constriction: a case report].

A case of Lassa fever associated with effusive constrictive pericarditis and bilateral atrioventricular annular constriction was reported. A 49-year-old man, who had been diagnosed by indirect fluorescent antibody test as the first case of Lassa fever in Japan, was referred to the Hiroo Hospital because of syncope, progressive hepatomegaly, ascites and pericardial effusion in spite of pericardiocentesis and corticosteroid therapy. On admission, his blood pressure was 92/60 mmHg and he had a paradoxical pulse.

Intracoronary urokinase in acute myocardial infarction: prevalence of total coronary occlusion during the early hours, effects on myocardial infarct size and left ventricular function, and outcome of residual coronary stenosis.

The effects of intracoronary thrombolysis (ICT) were studied in 88 acute myocardial infarction patients. Total coronary occlusion was observed in 67 of the 88 patients (76.1%) who were evaluated within 6 hours of the onset of symptoms.

[Aortic dissection presenting aortic regurgitation induced by diastolic prolapse of an intimal flap into the left ventricle: a case report].

A case of aortic dissection associated with aortic regurgitation which was induced by diastolic prolapse of an intimal flap into the left ventricular outflow tract was reported. This 57-year-old man, referred for evaluation of sudden onset of chest oppression and a heart murmur, was hypertensive for several years. His admission blood pressure was 184/44 mmHg, and a systolic ejection murmur and a diastolic decrescendo murmur were audible along the left sternal border.

[Transient obstruction of the left ventricular outflow tract induced by excessive alcohol intake: a case report].

A case of transient obstruction of the left ventricular outflow tract after excessive intake of alcohol was reported. This 41-year-old man was admitted to the Hiroo Hospital because of a syncopal attack experienced while walking. He had been drinking excessively for one week until the day before admission.
