BACKGROUND Previous pathological and clinical studies demonstrated an intimal defect in patients with acute aortic intramural hematoma (IMH). The purpose of this study was to investigate the prevalence and clinical outcome of intimal defect detected by multidetector computed tomography (MDCT) in patients with IMH. METHODS AND RESULTS We retrospectively(More)
BACKGROUND The purpose of this study was to investigate the clinical importance of newly developed ulcer-like projection (ULP) in patients with type B aortic dissection with closed and thrombosed false lumen (AD with CTFL), which is better known as aortic intramural hematoma. METHODS AND RESULTS A total of 170 patients with acute type B AD with CTFL were(More)
BACKGROUND Renal dysfunction is a common comorbidity in acute heart failure (AHF) patients. The prognostic significance of early treatment with tolvaptan in AHF patients complicated with renal dysfunction has not been elucidated. METHODS Post hoc analysis was performed on a randomized clinical study for prespecified prognostic endpoints and prespecified(More)
BACKGROUND  Limited data are available for sex-based differences in Japanese patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS  The study patients comprised 1,197 women and 3,182 men who underwent primary PCI for AMI in 2005-2007. Compared with the men, the women were(More)
BACKGROUND The management of aortic intramural hematoma (IMH) involving the ascending aorta (type A) has not been well-established. The purpose of this study was to clarify the long-term clinical outcomes of patients with type A IMH who were treated with medical therapy and timely operation. METHODS AND RESULTS Clinical data including operative mortality,(More)
OBJECTIVE The management of asymptomatic severe and very severe aortic stenosis (AS) remains unestablished. This study aimed to investigate the clinical outcomes of severe versus very severe AS patients. DESIGN A single centre, retrospective cohort study. PATIENTS AND METHODS The study retrospectively reviewed 108 conservatively treated patients with(More)
BACKGROUND More efficacious and/or safer decongestive therapy is clearly needed in acute heart failure (AHF) patients complicated by renal dysfunction. We tested the hypothesis that adding tolvaptan, an oral vasopressin-2 receptor antagonist, to conventional therapy with loop diuretics would be more effective treatment in this population. METHODS AND(More)
OBJECTIVES Surgical papillary muscle (PM) imbrication has been reported to be effective to relieve leaflet tethering in patients with functional mitral regurgitation (FMR). However, the mechanism that contributes to improvement of FMR by shortening the interpapillary muscle distance (IPMD) has not been well investigated. The purpose of the present study was(More)
AIMS To prospectively evaluate the relationship between left atrial volume (LAV) and the risk of clinical events in patients with hypertrophic cardiomyopathy (HCM). METHODS We enrolled a total of 141 HCM patients with sinus rhythm and normal pump function, and 102 patients (73 men; mean age, 61±13 years) who met inclusion criteria were followed for(More)
