Acute Pulmonary Thromboembolism: 14 Years of Surgical Experience.

Background: Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and to clarify the sustained long-term effects of surgery by comparing preoperative, postoperative, and long-term follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for a mean (median) period of 6.

Vanishing Venous Coronary Artery Bypass Grafts after Sepsis.

The dehiscence of saphenous vein grafts (SVGs) is a rare, often fatal, complication of coronary artery bypass grafting (CABG). We present the case of a 57-year-old man who underwent hemiarch graft interposition and CABG for a Stanford type A aortic dissection. Five months after discharge, the patient developed streptococcal sepsis caused by a hemodialysis catheter.

Use of a valved-conduit for exclusion of the infected portion in the prosthetic pulmonary valve endocarditis.

A 51-year-old male was admitted to the hospital with complaints of fever and hemoptysis. After evaluation of the fever focus, he was diagnosed with pulmonary valve infective endocarditis. Thus pulmonary valve replacement and antibiotics therapy were performed and discharged.

Successful surgical treatment of a right atrial myxoma complicated by pulmonary embolism.

A 76-year-old woman with hypertension was admitted to the hospital with complaints of chest pain and dyspnea. An echocardiogram and pulmonary computed tomography angiography showed right atrial myxoma complicated with pulmonary thromboembolism. An operation to resect the right atrial myxoma and pulmonary embolism was recommended; however, the patient refused and was discharged with anticoagulation therapy.

Efficacy of veno-arterial extracorporeal membrane oxygenation in acute myocardial infarction with cardiogenic shock.

Aim: We analyzed the results of acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) necessitating extracorporeal membrane oxygenation (ECMO), and investigated for the associated risk factors for poor clinical outcomes.

Methods: We retrospectively reviewed the medical records of 27 patients who required ECMO for AMI associated with CS between April 2006 and July 2010. Mean age was 63.

The effects of barrier materials on reduction of pericardial adhesion formation in rabbits: a comparative study of a hyaluronan-based solution and a temperature sensitive poloxamer solution/gel material.

Objective: This study was performed to examine the efficacy and safety of a hyaluronan solution (Guardix-SL) and a temperature sensitive poloxamer solution/gel material (Guardix-SG) on the prevention of pericardial adhesion in rabbits.

Methods: A total of 60 rabbits were divided into three groups according to material applied after epicardial abrasion: the control group (group CO), the Guardix SL group (group SL), and the Guardix SG group (group SG). The ejection fraction and the presence of pericardial effusion were evaluated by echocardiograms at the immediate postoperative period and 2 wk after the surgery.

Characterization of human monoclonal autoantibody Fab fragments against oxidized LDL.

Oxidized low-density lipoprotein (oxLDL) is a key autoantigen in atherosclerosis. The genetic structures and pathogenic roles of autoantibodies against this protein remain to be established. In this study, we cloned several monoclonal IgG autoantibody Fab fragments specific for oxLDL from peripheral blood lymphocytes of atherosclerosis patients, using phage display technology.

Molecular properties of excitation-contraction coupling proteins in infant and adult human heart tissues.

Excitation-contraction coupling (ECC) proteins in the human heart were characterized using human atrial tissues from different age groups. The samples were classified into one infant group (Group A: 0.2-7 years old) and three adult groups (Group B: 21-30; Group C: 41-49; Group D: 60-66).
