Single and multiple valve surgery in native valve infective endocarditis.

Background: Surgical treatment of infective endocarditis (IE) remains a challenge, especially in cases of multiple valve surgery. We evaluated the clinical outcomes of native valve IE and compared the outcomes of single valve surgery with those of multiple valve surgery.

Materials And Methods: From 1997 to 2011, 90 patients underwent surgery for native valve IE; 67 patients with single valve surgery (single valve group) and 23 patients with multiple valve surgery (multiple valve group).

Emergency one-stage hybrid surgery for ruptured aneurysm of the distal aortic arch.

Rupture of an aortic arch aneurysm is a life-threatening condition that requires emergency operation. For rupture of a distal arch aneurysm, we performed--with the patient under total circulatory arrest--an emergency total arch replacement with an elephant-trunk procedure, followed by one-stage antegrade stent-grafting. Prompt institution of cardiopulmonary bypass and total circulatory arrest has the advantage of lessening the risk of overt aortic rupture in this emergency situation.

Eleven years of experience with the neurologic complications in Korean patients with acute aortic dissection: a retrospective study.

Background: This study attempts to explore the clinical features, possible mechanisms and prognosis of the neurologic complications in patients with acute aortic dissection (AD).

Methods: Medical records of 278 consecutive patients with AD (165 with type A and 113 with type B dissection) over 11.5 years were retrospectively analyzed for clinical history, CT findings, neurologic complications and outcome.

Long-term mortality and morbidity after button Bentall operation.

Background And Aim Of The Study: The purpose of this study is to evaluate the long-term outcomes of the button Bentall procedure for the correction of aortic root disease.

Methods: A total of 195 patients who underwent the button Bentall procedure between 1997 and 2010 were studied. The main pathology was annuloaortic ectasia.

Circumferential left atrium resection for treating a giant left atrium.

Background: An enlarged left atrium (LA) is a major risk factor for atrial fibrillation (AF) recurrence after a maze operation.

Methods: Between 2000 and 2009, 35 patients underwent circumferential left atrium resection (CLAR), during mitral valve surgery. All patients had continuous AF.

Eleven years' experience with Korean cardiac myxoma patients: focus on embolic complications.

Background: Cardiac myxomas are rare but are the most common cardiac tumors. This study is based on our clinical experience with cardiac myxomas over a period of 11 years at Sejong General Hospital. We focused on the embolic complications of patients with cardiac myxoma.

Preoperative Extracorporeal Membrane Oxygenation for Severe Ischemic Mitral Regurgitation - 2 case reports -.

Indication for extracorporeal membrane oxygenation (ECMO) has been extended as the experience of ECMO in various clinical settings accumulates and the outcome after ECMO installation improves. We report two cases of successful mitral valve surgery for severe ischemic mitral regurgitation in patients on ECMO support for cardiogenic shock which developed upon coronary angiography.

The detection of pulmonary embolisms after a coronary artery bypass graft surgery by the use of 64-slice multidetector CT.

The purpose of this study was to examine the incidence of pulmonary embolism (PE) after a coronary artery bypass graft (CABG) using 64-slice multidetector CT (MDCT), and to determine the correlations between the occurrence of a PE and the clinical or surgical parameters. Three hundred and twenty-six consecutive patients, who underwent coronary CT angiography using 64-slice MDCT to assess the graft patency after CABG, were enrolled in this study. Additional axial CT images, which were reconstructed by adopting a large field of view and thinner image slices, were reviewed for the presence of PE.
