BACKGROUND Clopidogrel and aspirin are the most popular antiplatelet agents for anticoagulation management after coronary artery bypass grafting (CABG) in clinical practice, but there is neither a standard antiplatelet therapy for patients undergoing CABG, nor an exact conclusion about its effects on graft patency until now. METHODS One-hundred and(More)
BACKGROUND AND OBJECTIVES Although low-level laser therapy (LLLT) has been demonstrated to have a biomodulatory effect on periodontal tissue, no systematic review has exclusively addressed its effectiveness as an adjunct to non-surgical periodontal treatment. This study aimed to evaluate whether an additional benefit exists for the application of LLLT(More)
OBJECTIVE Congenital mitral valve regurgitation (MVR) is a rare disease found in adults. We report on our 5-year surgical experience with congenital MVR in adults. METHODS We reviewed the data for 48 consecutive patients (26 men), aged >18 years (median, 42 years; range, 18-78 years) who underwent operations for severe congenital MVR between June 2005 and(More)
OBJECTIVE The 3-dimensional arrangement of the ventricular mass remains controversial. In this study, we used magnetic resonance diffusion tensor imaging (MRDTI) in an attempt to determine whether the ventricular mass is arranged in the form of a helical ventricular myocardial band (HVMB) and what the geometrical features of the HVMB are in postmortem pig(More)
Patients with Ehlers-Danlos syndrome (EDS) type IV, an inherited connective tissue disorder, are predisposed to vascular and digestive ruptures, and arterial ruptures account for the majority of deaths. A 31-year-old man with EDS presented with an intramural aortoatrial fistula, severe aortic regurgitation, mitral valve prolapse, and severe tricuspid valve(More)
BACKGROUND Long-term warfarin therapy has been used to decrease thromboembolic events in patients with atrial fibrillation (AF) following bioprosthetic mitral valve replacement (BMVR) and left atrial appendage obliteration (LAAO). A retrospective study was conducted to investigate the efficacy of long-term warfarin or aspirin therapy in patients with AF(More)
OBJECTIVE To summarize the experience with emergency coronary artery bypass grafting (ECABG) for management of acute coronary syndrome and analyze the mid-term follow-up results. METHODS Forty-five ECABG surgeries were performed in 34 male and 11 female patients (aged 65.6∓5.8 years) for cardiogenic shock (5 cases), acute heart failure (6 cases) and(More)
Prosthetic valve thrombosis is a rare but life threatening complication of mechanical heart valve prosthesis. A 44-year-old woman diagnosed with rheumatic heart disease with severe mitral valve stenosis, moderate tricuspid valve insufficiency, and atrial fibrillation underwent transseptal mitral valve replacement and tricuspid valvuloplasty in our(More)
OBJECTIVE To analysis the influence of surgical revascularization on different timing after ST-elevation myocardial infarction (STEMI) on patients with coronary artery disease and left ventricular dysfunction. METHODS Clinical data of 225 patients admitted from January 2003 to July 2012 with history of STEMI and left ventricular dysfunction (ejection(More)
BACKGROUND The purpose of this study was to summarize our experience of extended ventricular septal myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM). METHODS Thirty-eight patients (26 men, 12 women) with HOCM underwent extended ventricular septal myectomy. The mean age was 36.3 years (range, 18-64 years). Diagnosis was made by(More)
