<b>Background: </b> There is scant information on secular trends in the incidence and survival of ischemic stroke subtypes. <b>Methods: The authors established three cohorts Hisayama residents age ≥40 years 1961 (1,618 subjects), 1974 (2,038 1988 (2,637 subjects). They followed up with each cohort for 12 years, comparing rate Morphologic examinations by autopsy or brain imaging was performed most cases all cohorts. <b>Results: age-standardized lacunar infarction significantly declined 59%...
Basal interventricular septum (IVS) hypertrophy (BSH) is characterized by a reduced aortoseptal angle and thickened basal IVS. The BSH shape suggests compression the longitudinally elongated ascending aorta (pseudohypertrophy), further suggesting possibility of surgical aortic wall shortening to improve BSH. We report case 77-year-old woman with an asymptomatic dissecting thoracic aneurysm clear Surgical root replacement longitudinal clearly improved BSH, demonstrating beneficial effects on...
Background:The long-term results of aortic valve replacement (AVR; n=737) with bileaflet mechanical prosthesis (MP) or Carpentier-Edwards Perimount bioprostheses (BP) were evaluated in different age groups.Methods and Results:Since 1981, a total 737 prostheses (424 MP vs. 313 BP) implanted for AVR 278 patients aged ≥70 years (79 199 BP), 191 60–69 (128 63 268 <60 (217 51 BP). Follow-up was completed 6,523 patient-years 98.5% cases. Among the years, both actuarial survival rate (P=0.0434)...
The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II was developed to improve the overestimation of surgical risk associated with original (additive and logistic) EuroSCOREs. purpose this study evaluate significance EuroSCORE by comparing its performance that EuroSCOREs in Japanese patients undergoing surgery on thoracic aorta. We have calculated predicted mortalities according additive EuroSCORE, logistic algorithms 461 who underwent aorta during a period 20 years...
We analyzed the mid-term left ventricular (LV) performance after aortic valve replacement (AVR). measured LV contractility (end-systolic elastance: Ees), afterload (effective arterial Ea) and efficiency (ventriculoarterial coupling: Ea/Ees; ratio of stroke work pressure-volume area: SW/PVA) based on transthoracic echocardiography data obtained before, approximately 1 year isolated AVR in 263 patients with stenosis (AS group; n=116), regurgitation (AR n=93) or (ASR n=54). The volume was...
Although surgical outcomes of total arch replacement have improved, the strategy for extended aneurysms remains controversial. We applied L-incision approach (combination left anterior thoracotomy and upper half-median sternotomy) single-stage repair extensive aneurysms. retrospectively reviewed operative patients who underwent or degenerative from 1999 to 2010. Operations were performed via median sternotomy in 47 (M group) was used 38 (L group). Through approach, we able complete distal...
Background:The long-term results achieved with aortic St. Jude Medical (SJM) mechanical prostheses in various age groups of Japanese patients have not been previously compared or reported.Methods and Results:Since 1981, a total 240 SJM valves were implanted 79 using the Standard model, 58 Hemodynamic Plus 103 Regent model for valve replacement (AVR). Follow-up was completed 2,397 patient-years 97.5% patients, among whom effect compared, subjects divided into younger (<65 years) older (≥65...
Aortic endografting can cause aortic stiffening. We aimed to determine the chronic effect of thoracic on cardiac afterload, function and remodelling.Eleven dogs were included, all except 1 was successfully assessed [endograft, n = 5; sham operation (control), 5]. deployed a stent graft in descending aorta. The ascending pressure flow measured, input impedance obtained by frequency analysis characteristic arterial compliance. Left ventricular pressure-volume relations measured with an...
The mechanisms of cardiac dysfunction after brain death, which are thought to be mainly associated with massive catecholamine release, have not been fully elucidated, especially respect the coronary circulation. aim this study was investigate changes in function artery and its contribution hemodynamic deterioration a canine death model.Brain induced by rapid inflation subdurally placed balloon catheter. Hemodynamic measurements including assessment left ventricular contractility using...
A 76-year-old woman presented with multiple brain infarctions in the right middle cerebral artery and vertebral area. Carotid sonography revealed a large mobile pedunculated mass brachiocephalic artery, which showed rapid growth despite treatment heparin aspirin. Graft replacement of was performed under selective perfusion deep hypothermia. Histology resected specimen aortic atherosclerotic plaque.
