OBJECTIVE Recent studies indicated that successful maze procedure for atrial fibrillation (AF) adjunct to mitral valve surgery provided a lower incidence of stroke and recurrence of AF. The purpose of this study is to review the 13-year experience of these combined procedures and to identify the risk factors and late outcomes of successful maze procedures(More)
Two children, aged 1 and 14 years with methicillin-resistant Staphylococcus aureus mediastinitis after pediatric open-heart surgery, were fitted with a vacuum-assisted closure system. Complete healing was achieved in both cases, and primary wound closure could be carried out without an omental flap after 6 and 16 days.
A 67-year-old man who underwent total aortic arch graft replacement with coronary artery bypass grafting developed postoperative Serratia mediastinitis. Re-operative debridement and irrigation were carried out. An infected aortic arch prosthesis was successfully treated by in situ disinfection followed by complete omental wrapping.
A 71-year-old patient with systemic lupus erythematosus, scleroderma and secondary antiphospholipid syndrome underwent coronary artery bypass grafting using cardiopulmonary bypass for angina pectoris. Postoperatively, new onset of thrombotic complications including neurological deficits was not recognized. She was discharged without any complications.
Thirteen cases of functional single ventricle who had undergone bidirectional Glenn procedure were divided into 2 groups according to presence (5) or absence (8) of additional pulmonary blood flow. Additional flow was preserved in cases with relatively small pulmonary artery index (PA index), and their sources were antegrade pulmonary blood flow (2), and(More)
We experienced a successful pediatric surgical case of partial anomalous pulmonary venous connection to the superior vena cava with cor triatriatum. Echocardiography and multidetector-row computed tomography showed partial anomalous pulmonary venous connection (right upper pulmonary vein connected to the high superior vena cava) and atypical cor triatriatum(More)
A 2-year-old girl with isolated unilateral absence of right pulmonary artery is described. Catheterization at 5 months demonstrated hypoplastic right pulmonary artery by pulmonary venous wedge angiography, and the patient underwent right Blalock-Taussig shunt and angioplasty of right pulmonary artery with autologous pericardial roll as an initial step.
