OBJECTIVES We evaluated the effects of statin treatments for each component of coronary plaques. BACKGROUND Effects of statin treatments on coronary plaques have not been sufficiently evaluated. METHODS One hundred patients without significant lesion stenosis underwent baseline and 12-month follow-up virtual histology (VH) intravascular ultrasound(More)
PURPOSES We sought to assess the frequency and clinical implications of left ventricular apical ballooning (LVAB) in patients who had been admitted to the medical ICU for noncardiac physical illnesses. METHODS Ninety-two consecutive patients who were admitted to the medical ICU from March to May 2003 were prospectively enrolled. Patients underwent(More)
BACKGROUND The proper treatment option for patients with type A intramural hematoma (IMH), a variant form of classic aortic dissection (AD), remains controversial. We assessed the outcome of our institutional policy of urgent surgery for unstable patients and initial medical treatment for stable patients with surgery in cases with complications. METHODS(More)
BACKGROUND Recent advances in three-dimensional (3D) echocardiography allow us to address uniquely 3D scientific questions, such as the mechanism of functional mitral regurgitation (MR) in patients with left ventricular (LV) dysfunction and its relation to the 3D geometry of mitral leaflet attachments. Competing hypotheses include global LV dysfunction with(More)
OBJECTIVES We sought to define the clinical importance of an integrated classification of bicuspid aortic valve (BAV) phenotypes and aortopathy using multidetector computed tomography (MDCT). BACKGROUND An association between BAV phenotypes and the pattern of valvular dysfunction or bicuspid aortopathy has yet to be definitely established. METHODS The(More)
BACKGROUND The timing and indications for surgical intervention to prevent systemic embolism in infective endocarditis remain controversial. We conducted a trial to compare clinical outcomes of early surgery and conventional treatment in patients with infective endocarditis. METHODS We randomly assigned patients with left-sided infective endocarditis,(More)
OBJECTIVES We sought to demonstrate the long-term natural course of descending aorta dilation after acute aortic dissection (AD) and identify early predictors for late aneurysmal change. BACKGROUND Aneurysmal dilation of the aorta is a critical late complication in AD patients. METHODS Contrast-enhanced computed tomography (CT) was performed during the(More)
OBJECTIVES We evaluated the axial location of plaque ruptures in native coronary arteries. BACKGROUND It is clinically important to understand the potential sites of plaque rupture. METHODS We performed three-vessel intravascular ultrasound (IVUS) examination in 392 patients; 231 had acute coronary syndrome (ACS) and 161 had stable angina pectoris(More)
OBJECTIVES The goal of this study was to test the hypothesis that the absence of direct flow communication through intimal tear in aortic intramural hematoma (AIH) involving the ascending aorta has different clinical impact on clinical course compared with typical aortic dissection (AD). BACKGROUND Although emergent surgical repair has been applied for(More)
Cerebral blood flow (CBF) is decreased and cognitive dysfunction develops in the advanced stages of heart failure. However, few data are available regarding the factors associated with decreased CBF. Fifty-two patients with advanced congestive heart failure (CHF) secondary to idiopathic dilated cardiomyopathy (ejection fraction <or=35%) and 10 healthy(More)
