To assess the usefulness of cone-beam CT (CBCT) during pulmonary angiography for the evaluation of organized thrombus at segmental or subsegmental arteries in patients with chronic thromboembolic pulmonary hypertension (CTEPH). The segmental and/or subsegmental pulmonary arteries of 13 patients with CTEPH were evaluated by CBCT. We classified representative(More)
Balloon pulmonary angioplasty (BPA) has been reported to improve haemodynamics and functional capacity, with an acceptable risk, in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are not candidates for pulmonary endarterectomy. However, right ventricular (RV) function, an important predictor in CTEPH, remains to be elucidated. We(More)
BACKGROUND The aim of this study was to clarify the incidence and clinical predictors of deep vein thrombosis (DVT) in patients with congestive heart failure (CHF) in Japan. METHODS AND RESULTS Between January 2003 and January 2008, 161 patients were admitted to Mie University Hospital with a diagnosis of CHF and underwent venous compression(More)
BACKGROUND The purpose of this study was to assess the use of the Günther Tulip Filter (GTF) for the management of venous thromboembolism (VTE). METHODS AND RESULTS Between December 2000 and April 2005, 118 patients (42 males, 76 females; mean age 60.5 years) diagnosed with VTE, underwent treatment with a GTF. The filter was left permanently in 52(More)
BACKGROUND The aim of this study was to evaluate the effects of acute right ventricular (RV) pressure overload (RVPO) on RV systolic function and its regional uniformity using speckle-tracking strain analysis in patients with acute pulmonary thromboembolism (APTE). METHODS Twenty-three patients with APTE (mean age, 59 +/- 16 years) and 23 age-matched and(More)
A 67-year-old woman with rheumatic aortic stenosis for 20 years was admitted to our hospital. Although she had no overt symptoms, she had severe aortic valve stenosis with a transvalvular pressure gradient of more than 150 mmHg. She had also been suffering from anemia and mild chronic renal failure. A peripheral blood smear showed numerous fragmented(More)
BACKGROUND Elevated levels of factor VIII (FVIII) have been suggested as important for the pathogenesis of venous thromboembolism (VTE). The objective of this study was to explore the association between elevated FVIII level and VTE in Japan. METHODS AND RESULTS 68 patients with objectively documented VTE and 40 controls were included. In the patients,(More)
Deep vein thrombosis (DVT) is a multifactorial disease caused by acquired risk factors such as a bed rest, surgery and malignancies. Although the factor V Leiden and the prothrombin-20210G>A mutation do not exist in Japanese populations, a mutation in protein S (PS) Tokushima (K196E) has been attracting attention in Japan. In this study, the genetic(More)
BACKGROUND The aim of this study was to investigate the impact of acute right ventricular pressure overload (RVPO) on left ventricular (LV) function and regional uniformity using speckle-tracking displacement and strain analyses in patients with acute pulmonary embolism (PE). METHODS Twenty-five patients with acute PE (mean age, 59 ± 16 years) and 25(More)
