OBJECTIVE The purpose of our study was to evaluate planimetry of the aortic valve area with 64-slice CT in comparison with transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in patients with aortic stenosis. MATERIALS AND METHODS Thirty-six patients with aortic valve disease referred for coronary 64-slice CT angiography were(More)
OBJECTIVES The purpose of this study was to evaluate whether multislice computed tomography (MSCT) provides a reliable, noninvasive imaging modality for identification of patients with degenerative aortic valve stenosis (AS) by quantifying the aortic valve area (AVA) in comparison to the accepted diagnostic standard transthoracic echocardiography (TTE).

OBJECTIVE In clinical practice, 64-MDCT coronary angiography is increasingly being used for exclusion of coronary artery disease. Therefore, the purpose of this study was to evaluate whether aortic valve regurgitation can be diagnosed with 64-MDCT in comparison with transthoracic echocardiography. MATERIALS AND METHODS Eighty-one consecutive patients were(More)
OBJECTIVES To prove whether intramyocardial transplantation of combined skeletal myoblasts (SM) and mononuclear bone marrow stem cells is superior to the isolated transplantation of these cell types after myocardial infarction in rats. METHODS In 67 male Fischer rats myocardial infarction was induced by direct ligature of the LAD. Seven days(More)
AIMS Despite the lower patency of venous compared with arterial coronary artery bypass grafts, approximately 50% of grafts used are saphenous vein conduits because of their easier accessibility. In a search for ways to increase venous graft patency, we applied the results of a previous pharmacological study screening for non-toxic compounds that inhibit(More)
BACKGROUND Cardiac surgery with cardiopulmonary bypass is associated with mechanical manipulation of the ascending aorta that occasionally leads to type A aortic dissection (AAD). METHODS AND RESULTS One hundred three patients with surgical repair for AAD following nonaortic cardiac surgery were identified. With the use of logistic regression modeling,(More)
OBJECTIVE The purpose of this study was to compare the diagnostic accuracy of 64-slice CT with that of invasive angiography in the detection of greater than 50% graft stenosis within 2 weeks of coronary artery bypass grafting and to investigate the clinical value of 64-slice CT. SUBJECTS AND METHODS Forty-one patients (70 grafts, 46 arterial and 24(More)
OBJECTIVE This study evaluates whether ECG-gated 16-MDCT coronary angiography provides a reliable imaging technique for detecting aortic regurgitation (AR). SUBJECTS AND METHODS We examined 71 patients prospectively with 16-MDCT angiography using retrospective ECG gating during the mid-to-end diastolic phase. A visible central valvular leakage area was(More)
OBJECTIVE The goal of this meta-analysis was to investigate the impact of cytomegalovirus hyperimmune globulin (CMVIG) on cytomegalovirus (CMV) infection, CMV disease, and mid-term survival in solid organ transplant recipients. METHODS Medline, EMBASE, and the Cochrane databases were searched since their inceptions until 2006. Inclusion criteria(More)
BACKGROUND Remote access perfusion and robotics have enabled totally endoscopic closure of atrial septal defect and patent foramen ovale. The aim of this study was to address learning curve issues of totally endoscopic atrial septal defect repair on the basis of a single-center experience and to investigate whether long cardiopulmonary bypass and aortic(More)
