Myxoma is the most common primary tumor of the heart. The common symptoms of myxoma can be similar to those of infective endocarditis, which include fever, weight loss, fatigue and arthralgia, but it is very rare for a myxoma to become infected. We report on a case of a 76-year-old male patient with fever and loss of conscious-ness, and he underwent an emergency operation after suffering shock state due to the infected myxoma.

Streptococcus gordonii is a Gram-positive, facultative anaerobic and non-motile cocci. S. gordonii is a member of oral flora and a pioneer species that initiate the dental biofilm formation. S. gordonii has also been implicated in the pulpitis of primary teeth as well as systemic diseases such as infective endocarditis and septic arthritis. S. gordonii is associated with oral, respiratory, and gastrointestinal tract infections. S. gordonii KCOM 1506 (= ChDC B679) was isolated from a human acute pulpitis lesion. Here, we present the complete genome sequence of S. gordonii KCOM 1506.

Streptococcus mitis is a Gram-positive, facultative anaerobic, alpha-hemolytic, and nonmotile cocci. S. mitis is a viridans streptococci and a normal commensal of throat, nasopharynx, and mouse and is associated with infective endocarditis, septicemia, and meningitis. S. mitis KCOM 1350 (= ChDC B183) was isolated from a human mandibular osteomyelitis lesion. Here, we present the complete genome sequence of S. mitis KCOM 1350.

Cutibacterium acnes (formerly Propionibacterium acnes) is an anaerobic, Gram-positive rod and that is a normal flora of human skin and mucosal surface as well as an opportunistic pathogen related to acnes vulgaris, sarcoidosis, brain abscess, endocarditis, periodontitis, and endodontic infections. C. acnes KCOM 1861 (= ChDC B594) was isolated from a human jaw osteomyelitis lesion. Here, we present the complete genome sequence of C. acnes KCOM 1861.

Quadricuspid aortic valve is a rare congenital abnormality but it is well recognized as the cause of significant aortic regurgitation. We describe 5 patients who underwent surgery for severe aortic regurgitation associated with quadricuspid valve. In all patients, this abnormality had been incidentally detected during surgery. Two of the patients had infective endocarditis. In accordance with the Hurwitz and Roberts classification, two valves were type d, two were type a, and one was type c.

We experienced a case of infective endocarditis of aortic valve and tricuspid valve associated with a fistula between aorta and right ventricle. The patient was 35 years old woman and showed severe congestive heart failure. Large and multiple vagetations were found on the valvular surfaces and a fistula was present between aorta and right ventricle. Probably infective endocarditis of aortic valve resulted in annular abscess and as it healed, a fistula was formed and tricuspid valve endocarditis followed. We replaced the aortic valve and tricuspid valve with St. Jude mechanical prostheses, and closed the fistula opening with suture. The postoperative course was smooth and the patient has no problems till now 4 months after operation.

A 42 year old male was operated with aortic root abscess and pseudoaneurysm. Aortic valve vegetations which measured $8\times5$ cm and root abscess were removed and debrided. We reconstructed root and noncoronary sinus with autopericardium. Antibiotics were administered for 4 weeks. In general, Aortic root abscess recurs frequently and mortality is high. It is usually requires early surgical eradication with antibiotics medication.

Cutibacterium acnes is a member of normal flora of human skin, conjunctiva, intestinal tract, the external auditory canal as well as oral cavity. It has been identified as an opportunistic pathogen related to acne vulagris, endocarditis infections, sarcoidosis, brain abscess, periodontitis, and osteomyelitis of the humerus. C. acnes KCOM 1315 (= ChDC KB81) was isolated from a human jaw osteomyelitis lesion. Here, we present the complete genome sequence of C. acnes KCOM 1315.

Between October 1991 and May 1995, 256 "New Duromedics Valve"(Edward TEKNA Bileaflet Valve) were implanted in 208 adult patients(171 mitral, 82 aortic and 3 tricuspid) with age ranging from 18 years to 70 years(mean 48.2$\pm$ 11.6 years). Postoperative complication rates were 12.2%, but there was none valve related one. Overall early mortality rate were 1.4%(1.6% for MVR, 2.1% for DVR, and none for AVR or TVR) respectively. Follow-up was 99% completed ranging in duration from 2 months to 46 months. There were 6 valve-related late complications(2.9%) with 2 patients with upper gastrointestinal bleeding, 2 with cerebral thxomtioembolism, 1 with valve thrombosis and 1 with valve endocarditis. Freedom from these valve-related major complications were 89.9% at 40 months. There were 5 late deaths(2.4%). one of these late deaths was considered valve-related. Overall actuarial survival rates at 40 months were 95.5%, 96.8% for mitral, 97.1% for aortic, 100% for tricuspid, and 92.0% for double valve replacement respectively. Preoperative New York Heart Association functional class were 2.9, and 1.3 in post-operative state. We have been trying to keep the international normalized ratio(INR) with range of 2.5 to 3.0. The INR of 4 patients of 5 with anticoagulant ralated complications was beyond the range. To reduce the rate of anticoagulant related complications, we felt very strongly that the INR should be kept between 2.5 and 3.0. In our cases, there was no structural failure or significant hemolysis in the absence of periprosthetic leak. This experience encourages us to continue using the "New Duromedics Valve".omedics Valve".uot;.

Purpose : This study was performed to find the chief clinical problems associated with the ages of adult patients of tetralogy of Fallot(TOF) who had undergone total correction. Methods : Of the 30 patients who were registered at the Grown-Up Congenital Heart Disease (GUCH) Clinic of Samsung Medical Center for TOF, a retrospective investigation was carried out on 28 patients who underwent total correction. Results : Mean age at retrospective study was 30.8(range : 16-53) years old. Age at total correction was 15.8(range : 2-49) years old. Problems after corrective surgery were assessed. They were arrhythmia, pulmonary valve regurgitation, left pulmonary artery stenosis, residual ventricular septal defect, mitral valve regurgitation, tricuspid valve regurgitation, right ventricle outflow tract obstruction, aortic valve regurgitation, infective endocarditis and protein losing enteropathy. After repair of TOF, such arrhythmias as atrial arrhythmia and AV conduction disturbances were observed in some patients. Cardiomegaly was found significantly in the subjects with arrhythmia(P<0.05), and arrhythmia was less observed in patients who underwent surgery at a young age. Eight patients required a reoperation; the main indications were residual ventricular septal defect, right ventricle outflow tract obstruction and peripheral pulmonary artery stenosis. Conclusion : The majority of the patients seemed to live normal lives after Tetralogy of Fallot repair. However, as residual anatomic and functional abnormalities exist postoperatively, continued careful follow-up is needed to detect and correct structural and functional abnormalities.
